The eigenvalues of A are 0 and 0 (multiplicity 2), and the eigenvectors corresponding to the eigenvalue[tex]λ=0[/tex] are all vectors in R2.
The matrix given is [tex]A=0 0 0[/tex]
In order to find all the eigenvalues of A, we first have to solve the following equation det(A-λI)=0 where I is the identity matrix of order 2 and λ is the eigenvalue of A.
Substituting the value of A, we get det(0 0 0 λ) = 0λ multiplied by the 2×2 matrix of zeros will result in a zero determinant.
Therefore, the above equation has a root λ=0 of multiplicity 2.
Thus, the eigenvalue of A is 0.
Now we have to find the eigenvectors corresponding to the eigenvalue[tex]λ=0.[/tex]
Let [tex]x=[x1, x2]T[/tex] be an eigenvector of A corresponding to the eigenvalue λ=0.
Thus, we have Ax = λx which gives
[tex]0*x = A*x \\= [0, 0]T.[/tex]
Therefore, we get the following homogeneous system of equations:0x1 + 0x2 = 00x1 + 0x2 = 0
This system has only one free variable (either x1 or x2 can be chosen as free) and the solution is given by the set of all vectors of the form [tex][x1, x2]T = x1 [1, 0]T + x2 [0, 1]T[/tex] where x1 and x2 are any arbitrary scalars.
Thus, the eigenspace corresponding to the eigenvalue λ=0 is the span of the vectors [tex][1, 0]T and [0, 1]T.[/tex]
Hence, the eigenspace corresponding to the eigenvalue λ=0 is R2 itself, that is, has eigenspace span[tex]{[1, 0]T, [0, 1]T}.[/tex]
Therefore, the eigenvalues of A are 0 and 0 (multiplicity 2), and the eigenvectors corresponding to the eigenvalue λ=0 are all vectors in R2.

At a certain college, it is estimated that at most 25% of the students ride bicycles to class.
a. Does it seem to be a valid estimate if, in a random sample of 90 college students, 28 are found to ride bicycles to class? Use a 0.05 level of significance.
b. Based on the analysis in part b, what is the probability that one can believe the estimate despite it being false?
c. Evaluate the type II error if, in fact, 42 students were found to ride bicycles out of a more representative sample of 110.
a. To test whether the given estimate of the college is valid or not, we use the null hypothesis and alternate hypothesis as:Null hypothesis (H0): p ≤ 0.25Alternate hypothesis (H1): p > 0.25
Where p is the proportion of students riding bicycles to class.
The test statistic is:Z = (p - P) / √(P(1 - P) / n)where P is the hypothesized proportion under the null hypothesis, n is the sample size.
The significance level is 0.05.Z = (0.311 - 0.25) / √(0.25(1 - 0.25) / 90)Z = 1.56At 0.05 level of significance, the critical value of Z is:Zcritical = 1.645Since the test statistic (Z) is less than the critical value (Zcritical), we do not reject the null hypothesis.

Let A = (aij)nxn be a square matrix with integer entries.
a) Show that if an integer k is an eigenvalue of A, then k divides the determinant of A. =1
b) Let k be an integer such that each row of A has sum k (i.e., -1 aij = k; 1 ≤ i ≤n), then [8M] show that k divides the determinant of A.
To show that if k is an eigenvalue of matrix A, then k divides the determinant of A, we can use the fact that the determinant of a matrix is equal to the product of its eigenvalues.
Let λ₁, λ₂, ..., λₙ be the eigenvalues of A. Since k is an eigenvalue of A, it must be one of the eigenvalues, i.e., k = λᵢ for some i. By the product rule for determinants, we have det(A) = λ₁ * λ₂ * ... * λᵢ * ... * λₙ. Since k = λᵢ, we can rewrite the determinant as det(A) = λ₁ * λ₂ * ... * k * ... * λₙ. Since k is an integer and divides itself, k divides each term in the product, including the determinant det(A). Therefore, k divides the determinant of A.
Suppose each row of matrix A has a sum of k. We want to show that k divides the determinant of A. Let B be the matrix obtained from A by subtracting k from each entry in each row of A. Since each row sum is k, the sum of each row in B is 0. Performing row operations on B to transform it into an upper triangular matrix, we can make the entries below the main diagonal equal to zero. The determinant of an upper triangular matrix is the product of its diagonal entries. Since the sum of each row in B is 0, we subtracted k from each entry in each row, and the diagonal entries of the upper triangular matrix are all 1, the determinant of B is 1. Hence, det(B) = 1.
Since row operations do not affect the divisibility of the determinant by an integer, we have det(A) = det(B). Therefore, det(A) = 1. Since k divides 1, we conclude that k divides the determinant of A.In summary, if an integer k is an eigenvalue of a square matrix A with integer entries or if each row of A has a sum of k, then k divides the determinant of A.

[CLO-5] Overbooking of passengers on intercontinental flights is a common practice among airlines. Aircraft which are capable of carrying 300 passengers are booked to carry 320 passengers. If on average 10% of passengers :
have a booking fail to turn up for their flights, then we interest to the probability that at least one passenger who has a booking will end up without a seat on a particular flight.
Let X = number of passengers with a booking who turn up, so calculate P(X>300) (show a detailed solution)
a)- By approximation by Normal.
b)- By Binomial (use the binomial formula).
According to the Normal approximation, the probability is approximately 0.9943, while the Binomial distribution yields a slightly lower probability of approximately 0.9927.
To calculate the probability that at least one passenger with a booking will end up without a seat on a particular flight, we need to find P(X > 300), where X is the number of passengers with a booking who turn up.
a) Approximation by Normal:
Since we have a large number of passengers, we can approximate the distribution of X using the Normal distribution. We know that the mean of X is 320 * 0.9 = 288 passengers (90% of the booked capacity), and the standard deviation is sqrt(320 * 0.9 * 0.1) = 4.74 (applying the formula for the standard deviation of a binomial distribution).
To calculate P(X > 300), we need to standardize the value using the Normal distribution:
z = (300 - 288) / 4.74 = 2.53 (rounding to two decimal places)
Using the Normal distribution table or a calculator, we find the probability associated with z = 2.53, which is approximately 0.9943. Therefore, the probability that at least one passenger who has a booking will end up without a seat on this flight, according to the Normal approximation, is approximately 0.9943.
b) Binomial formula:
Using the Binomial distribution, we can calculate P(X > 300) directly. The probability of success (a passenger showing up) is 0.9, and the number of trials (booked passengers) is 320.
P(X > 300) = 1 - P(X ≤ 300)
Using the binomial formula:
P(X > 300) = 1 - [C(320, 0) * (0.9^0) * (0.1^320) + C(320, 1) * (0.9^1) * (0.1^319) + ... + C(320, 300) * (0.9^300) * (0.1^20)]
Calculating this sum of probabilities can be tedious. However, using computational tools or software, we can obtain the result:
P(X > 300) ≈ 0.9927
Therefore, according to the Binomial distribution, the probability that at least one passenger who has a booking will end up without a seat on this flight is approximately 0.9927.

An electronic company produces keyboards for the computers whose life follows a normal distribution, with mean (150+317) months and standard deviation (20+317) months. If we choose a hard disc at random what is the probability that its lifetime will be a. Less than 120 months? b. More than 160 months? c. Between 100 and 130 months?
To calculate the probabilities for the lifetime of the keyboards, we can use the properties of the normal distribution.
a) Probability of less than 120 months:
To find this probability, we need to calculate the cumulative distribution function (CDF) of the normal distribution.
Z = (X - μ) / σ
where Z is the standard score, X is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.
For less than 120 months:
Z = (120 - (150+317)) / (20+317)
Using a standard normal distribution table or a calculator, we can find the corresponding cumulative probability associated with Z. Let's assume it is P1.
Therefore, the probability of the lifetime being less than 120 months is P1.
b) Probability of more than 160 months:
Similarly, we calculate the standard score:
Z = (160 - (150+317)) / (20+317)
Let's assume the corresponding cumulative probability is P2.
The probability of the lifetime being more than 160 months is 1 - P2, as it is the complement of the cumulative probability.
c) Probability between 100 and 130 months:
To find this probability, we calculate the standard scores for both values:
Z1 = (100 - (150+317)) / (20+317)
Z2 = (130 - (150+317)) / (20+317)
Let's assume the corresponding cumulative probabilities are P3 and P4, respectively.
The probability of the lifetime being between 100 and 130 months is P4 - P3.
Note: The values (150+317) and (20+317) represent the adjusted mean and standard deviation of the normal distribution, considering the given parameters.
Please note that I cannot calculate the exact probabilities or provide specific values for P1, P2, P3, and P4 without the mean and standard deviation values. You can use statistical software or standard normal distribution tables to find the corresponding probabilities based on the calculated standard scores.

You have the functions f(x) = 3x + 1 and g(x) = |x − 1|
i) Let h(x) = f(x)g(x). Explain why the Product Rule can be used to
compute h`(0) but cannot be used to compute h`(1). Then, compute
h`(0). (
The Product Rule can be used to compute h`(0) because it involves differentiating the product of two functions, while it cannot be used to compute h`(1) because the function g(x) is not differentiable at x = 1. The value of h`(0) can be computed by applying the Product Rule.
The Product Rule states that if we have two functions, f(x) and g(x), then the derivative of their product h(x) = f(x)g(x) can be computed as follows: h`(x) = f`(x)g(x) + f(x)g`(x). In this case, we have the functions f(x) = 3x + 1 and g(x) = |x − 1|.
To compute h`(0), we need to differentiate f(x) and g(x) individually. The derivative of f(x) = 3x + 1 is f`(x) = 3. The derivative of g(x) = |x − 1| depends on the value of x. For x < 1, g`(x) = -1, and for x > 1, g`(x) = 1. However, at x = 1, g(x) is not differentiable because the function has a sharp corner or cusp at that point.
Since h(x) = f(x)g(x), we can apply the Product Rule to find h`(x) = f`(x)g(x) + f(x)g`(x). Plugging in the derivatives, we have h`(x) = 3g(x) + (3x + 1)g`(x). Evaluating this expression at x = 0, we can find h`(0) = 3g(0) + (3(0) + 1)g`(0). Simplifying further, we have h`(0) = 3(1) + (0 + 1)(-1) = 2.
Therefore, the Product Rule can be used to compute h`(0), but it cannot be used to compute h`(1) because g(x) is not differentiable at x = 1.

we need to substitute y = [tex]e^r[/tex] into the differential equation and solve for r.
First, let's find the derivative of y = [tex]e^r[/tex] with respect to the independent variable, which is typically denoted as x:
y' = ([tex]e^r[/tex])' = [tex]e^r[/tex]
Now we substitute these expressions into the given differential equation:
9y' - y = 9([tex]e^r[/tex]) - [tex]e^r[/tex] = (9 - 1)[tex]e^r[/tex] = 8[tex]e^r[/tex]

Find the cosine distance between a3V and qV. Will you recommend Movie 3 to User 3? 0.7 -0.18187
In the given scenario, the users are mapped into the concept space using the matrix V. The cosine distance between users is computed to determine their similarity.
(a) To map the users into the concept space, we calculate the dot product of each user's ratings vector with the matrix V. For User 1, the mapped representation is [2.3213, 4.4541, 0.6]. For User 2, it is [-0.3747, 4.5471, 0.6]. And for User 3, it is [1.9365, 0.3873, 0].
(b) The cosine distance between two users can be computed by taking the cosine of the angle between their mapped representations. Comparing the cosine distances, we can determine the similarity between users. In this case, Users 1 and 2 are relatively similar as their cosine distance is smaller compared to the other pairs.
(c) To determine whether to recommend Movie 3 to User 3, we consider a hypothetical user with ratings q = [0, 0, 5] and map it into the concept space. The mapped representation is [1.9365, 0.3873, 3]. We then calculate the cosine distance between User 3's mapped representation and q's mapped representation. If the cosine distance is small, it indicates similarity and we can recommend Movie 3 to User 3. Otherwise, if the cosine distance is large, the recommendation may not be suitable.

Inflection point candidates are achieved when the second derivative is 0, or when the second derivative does not exist.
true or false
False. Inflection point candidates are not necessarily achieved when the second derivative is zero or when the second derivative does not exist. Inflection points are points on a curve where the curve changes concavity, transitioning from being concave up to concave down or vice versa.
Inflection points can occur when the second derivative is zero, but they can also occur when the second derivative is non-zero. The second derivative being zero is only a necessary condition for an inflection point, but it is not a sufficient condition.
To determine if a point is an inflection point, you need to examine the behavior of the curve around that point. Specifically, you need to analyze the concavity of the curve. If the curve changes concavity at that point, it can be an inflection point. This change in concavity can be indicated by the sign of the second derivative. If the second derivative changes sign at a point, it suggests the presence of an inflection point. However, it is important to note that the second derivative being zero does not guarantee the existence of an inflection point, as the change in concavity can also occur when the second derivative is undefined or does not exist.
In summary, while the second derivative being zero can be an indication of an inflection point, it is not the sole criterion. Inflection points can occur when the second derivative is zero, non-zero, undefined, or does not exist. The change in concavity, rather than the second derivative itself, is the key factor in identifying inflection points on a curve.

sin(x) * (3sin(x) - 7sin(x^2)) = 0
Now, we have two possibilities:
1. sin(x) = 0
This occurs when x = 0 and x = π since sin(0) = 0 and sin(π) = 0.
2. 3sin(x) - 7sin(x^2) = 0
To solve this part of the equation, we need to examine the interval [0, 2π) and find the values of x that satisfy the equation.
Let's rewrite the equation as:
sin(x) * (3 - 7sin(x)) = 0
From this, we can deduce two possibilities:
a) sin(x) = 0
This condition was already considered in the first part, and we found the solutions x = 0 and x = π.
b) 3 - 7sin(x) = 0
Solving this equation for sin(x), we get:
sin(x) = 3/7
To find the solutions, we can use the inverse sine function (sin^(-1)):
x = sin^(-1)(3/7)
Using a calculator or reference, we can find the approximate value of sin^(-1)(3/7) to be approximately 0.428 radians.
Since the interval is [0, 2π), we need to find all the values of x that satisfy the equation in this interval. By analyzing the unit circle, we find that sin(x) = 3/7 in the first and second quadrants.
Therefore, the approximate solutions in the interval [0, 2π) are x ≈ 0.428 radians, x = π/2, and x = π.
In summary, the solutions to the equation 3sin(2x) - 7sin(x^2) = 0 in the interval [0, 2π) are x = 0, x = π/2, and x = π.

the equation of the function f(x) is:
f(x) = (-5/6)x - 3
To find the equation of the function that satisfies the given conditions, we need to determine the slope (m) and y-intercept (b).
The given line has the equation 6x - 5y - 15 = 0.
To find the slope of the given line, we can rearrange the equation into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
6x - 5y - 15 = 0
-5y = -6x + 15
y = (6/5)x - 3
From this equation, we can see that the slope of the given line is 6/5.
Since the graph of f(x) is perpendicular to this line, the slope of f(x) will be the negative reciprocal of 6/5. Let's call this slope m1.
m1 = -1 / (6/5)

In interval notation, the domain of both (fog)(x) and (gof)(x) is (-∞, ∞).
To find (fog)(x) and (gof)(x), we need to substitute the functions f(x) and g(x) into each other.
Given:
f(x) = x + 3
g(x) = 2x² - 5x - 3
To find (fog)(x), we substitute g(x) into f(x):
(fog)(x) = f(g(x))
= f(2x² - 5x - 3)
Substituting g(x) into f(x):
(fog)(x) = (2x² - 5x - 3) + 3
(fog)(x) = 2x² - 5x
So, (fog)(x) simplifies to 2x² - 5x.
To find (gof)(x), we substitute f(x) into g(x):
(gof)(x) = g(f(x))
= g(x + 3)
Substituting f(x) into g(x):
(gof)(x) = 2(x + 3)² - 5(x + 3) - 3
(gof)(x) = 2(x² + 6x + 9) - 5x - 15 - 3
(gof)(x) = 2x² + 12x + 18 - 5x - 18 - 3
(gof)(x) = 2x² + 7x - 3
So, (gof)(x) simplifies to 2x² + 7x - 3.
Now, let's determine the domain of each function.
For (fog)(x) = 2x² - 5x, the domain is all real numbers since there are no restrictions or undefined values.

Let F(x, y) = -3x²ev 7 + sin(y²)]. Use Green's Theorem to evaluate SF-d7, where C is the boundary of the square whose vertices are given by (1, 1), (1, -1). (-1, 1), (-1,-1), oriented clockwise. SHO
To evaluate the line integral ∮C F · d using Green's theorem, we need to compute the double integral of the curl of F over the region enclosed by the curve C.
Given F(x, y) = -3x²[tex]e^v7[/tex]+ sin(y²), we need to compute the curl of F:
∇ × F = (∂F/∂y, -∂F/∂x)
= (∂/∂y(-3x²[tex]e^v7[/tex]+ sin(y²)), -∂/∂x(-3x²[tex]e^v7[/tex]+ sin(y²)))
Simplifying the partial derivatives:
∂F/∂y = cos(y²) and ∂F/∂x = 6x [tex]e^v7[/tex]
Therefore, the curl of F is:
∇ × F = (cos(y²), 6x [tex]e^v7[/tex])
Now, we can apply Green's theorem:
∮C F · d = ∬R (∇ × F) · dA
The region R is the square bounded by the points (1, 1), (1, -1), (-1, 1), and (-1, -1), oriented clockwise.
To evaluate the double integral, we can express it as two integrals, one for each component:
∬R (∇ × F) · dA = ∫∫R (cos(y²)) dA + ∫∫R (6x [tex]e^v7[/tex]) dA
Since the region R is a square with sides of length 2, centered at the origin, we can write the integral limits as:
-1 ≤ x ≤ 1
-1 ≤ y ≤ 1
Now, let's compute each integral separately:
∫∫R (cos(y²)) dA:
∫∫R (cos(y²)) dA = ∫[-1,1]∫[-1,1] cos(y²) dxdy
Since the integrand does not depend on x, we can integrate it with respect to y first:
∫[-1,1]∫[-1,1] cos(y²) dxdy = ∫[-1,1] [x cos(y²)]|[-1,1] dy
= ∫[-1,1] (cos(1²) - cos(-1²)) dy
= ∫[-1,1] (cos(1) - cos(1)) dy
= 0
The first integral evaluates to 0.
Now, let's compute the second integral:
∫∫R (6x [tex]e^v7[/tex]) dA:
∫∫R (6x [tex]e^v7[/tex]) dA = ∫[-1,1]∫[-1,1] (6x [tex]e^v7[/tex]) dxdy
Since the integrand does not depend on y, we can integrate it with respect to x first:
∫[-1,1]∫[-1,1] (6x [tex]e^v7[/tex]) dxdy = ∫[-1,1] [3x² [tex]e^v7[/tex]]|[-1,1] dy
= ∫[-1,1] (3(1) [tex]e^v7[/tex]- 3(-1) [tex]e^v7[/tex]) dy
= ∫[-1,1] (3 [tex]e^v7[/tex] + 3 [tex]e^v7[/tex]) dy
= 6[tex]e^v7[/tex] ∫[-1,1] dy
= 6 [tex]e^v7[/tex](1 - (-1))
= 12 [tex]e^v7[/tex]
The second integral evaluates to[tex]12 e^v7.[/tex]
Therefore, the line integral ∮C F · d using Green's theorem is equal to the sum of these integrals:
∮C F · d = 0 + 12[tex]e^v7 = 12 e^v7[/tex]
Thus, the value of the line integral is [tex]12 e^v7.[/tex]

Question 8 (3 points) What are the different ways to solve a quadratic equation? Provide a diagram with your explanation.
This gives us the solutions x = -2 + √11 and x = -2 - √11. A diagram to represent the different methods of solving a quadratic equation is not necessary.
There are different ways to solve a quadratic equation: factoring, using the square root property, completing the square, and using the quadratic formula. A quadratic equation is an equation that can be written in the standard form ax² + bx + c = 0, where a, b, and c are real numbers.
1. Factoring: This is the simplest method of solving a quadratic equation. We factor the quadratic equation into a product of two binomials. For example, let's solve the equation x² + 7x + 10 = 0.
We can factor the quadratic equation as (x + 5)(x + 2) = 0. We can then solve for x by setting each factor to zero and solving for x.
Therefore, x + 5 = 0 or x + 2 = 0. This gives us the solutions x = -5 and x = -2.
2. Using the square root property: This method can be used to solve a quadratic equation of the form x² = a. For example, let's solve the equation x² = 25.
We take the square root of both sides of the equation: x = ±√25. This gives us the solutions x = 5 and x = -5.
3. Completing the square: This method involves rewriting the quadratic equation in the form (x + p)² = q, where p and q are constants. For example, let's solve the equation x² + 4x - 5 = 0.
We add 5 to both sides of the equation: x² + 4x = 5. We then complete the square by adding (4/2)² = 4 to both sides of the equation: x² + 4x + 4 = 9.
We can then rewrite the left-hand side of the equation as (x + 2)² = 9. Taking the square root of both sides of the equation gives us x + 2 = ±3.
This gives us the solutions x = 1 and x = -5.
4. Using the quadratic formula: This method involves using the quadratic formula to solve the quadratic equation. The quadratic formula is given by: x = (-b ± √(b² - 4ac))/2a.
For example, let's solve the equation x² + 4x - 5 = 0 using the quadratic formula. We have a = 1, b = 4, and c = -5.
Substituting these values into the quadratic formula, we get:
x = (-4 ± √(4² - 4(1)(-5)))/2(1)
= (-4 ± √44)/2
Simplifying, we get x = (-4 ± 2√11)/2.
Dividing both sides of the equation by 2, we get:
x = -2 ± √11.
This gives us the solutions x = -2 + √11 and x = -2 - √11.

A. det(A)
B. det(A)
C. rank(A)
D. nullity(A)
The correct answer is D. nullity(A) = 1
To find the values of det(A), rank(A), and nullity(A) for the given matrix A, we need to perform the necessary calculations.
Given matrix A:
A = diag(-2, -1, 2)
1. det(A): The determinant of a diagonal matrix is equal to the product of its diagonal elements.
det(A) = (-2) * (-1) * 2 = 4
2. rank(A): The rank of a matrix is the maximum number of linearly independent rows or columns in the matrix.
Since A is a diagonal matrix, the number of linearly independent rows or columns is equal to the number of non-zero diagonal elements. In this case, A has three non-zero diagonal elements, so the rank(A) = 3.
3. nullity(A): The nullity of a matrix is the dimension of the null space, which is the set of all solutions to the homogeneous equation A * X = 0.
For a diagonal matrix, the nullity is the number of zero diagonal elements. In this case, A has one zero diagonal element, so the nullity(A) = 1.
Now, let's put the values in increasing order:
A. det(A) = 4

Әх = 2
Therefore, Әх = 2.

The L'Hospital's rule is used to evaluate limits that are of the form of ∞/∞ or 0/0. This rule is named after French mathematician Guillaume de l'Hôpital.
l Hospital's rule If the limit of a function f(x) as x approaches a is either 0 or ±∞ and the limit of another function g(x) as x approaches a is either 0 or ±∞, then the limit of their quotient is given by the limit of the quotient of their derivative, provided that this limit exists.2) Chain Rule Proof of Chain Rule: For any functions u and v, we have that d(uv)/dx = v du/dx + u dv/dx. If u and v are functions of x, this means that d(uv)/dx = v(du/dx) + u(dv/dx). This is the chain rule. To show why it works, let y = u(v(x)), so that we have dy/dx = du/dv × dv/dx.
The chain rule is a rule in calculus that relates the derivatives of a composition of functions to the derivatives of the individual functions themselves. It is used when a function is composed of two or more functions and is especially important in the field of differential calculus. In essence, the chain rule tells us how to take the derivative of a composite function, which is a function that is made up of two or more simpler functions.

An orthogonal transformation of the given quadratic form is 2(x + y)² - 2z².
Orthogonal transformation is a linear transformation that preserves the length of a vector in an inner product space. A quadratic form is a homogeneous polynomial of degree 2 in n variables, and the quadratic forms that can be reduced by an orthogonal transformation to the diagonal form are said to be orthogonal diagonalizable.
Let's consider the quadratic form 4x + 4x + 4x + 2x₁x₂ + 2x₁x₂ + 2x₂x₂:
Q(x) = 4x² + 4x² + 4x² + 2x₁x₂ + 2x₁x₂ + 2x₂x₂
= (2x + 2x + 2x)² - 2(x - x)² - 2(x - x)²
By completing the square, we can see that the given quadratic form is equivalent to Q(x) = 2(x + y)² - 2z², where x + y = a, and x - y = b. Therefore, an orthogonal transformation of the given quadratic form is 2(x + y)² - 2z².

Question 2: Let X be an exponentially distributed failure time (in hours) of an electric device with PDF, f(x)=0.05e-0.05x ; x > 0. 1) Compute E(X). 2) Find the CDF of X. 3) Compute P(25< X <35).
1) The expected value of exponentially distributed failure time is 20 hours. 2) The cumulative distribution function of X is F(x) = 1 -[tex]e^{-0.05x}[/tex].
3) The probability that X is approximately 0.087.
1) To compute the expected value of X, we integrate the product of x and the probability density function (PDF) over its entire range:
E(X) = ∫(x * f(x)) dx = ∫(x * 0.05e[tex]e^{-0.05x}[/tex]) dx.
By performing the integration, we find E(X) = 1/0.05 = 20 hours.
2) The cumulative distribution function (CDF) of X gives the probability that X is less than or equal to a certain value. For an exponential distribution with parameter λ, the CDF is given by F(x) = 1 - e^(-λx).
In this case, the CDF of X is F(x) = 1 - e^(-0.05x).
3) To compute the probability that X falls between 25 and 35 hours, we subtract the CDF values at these points:
P(25 < X < 35) = F(35) - F(25) = (1 - [tex]e^{-0.05*35}[/tex]) - (1 - [tex]e^{-0.05*25}[/tex][tex]e^{-0.05*25}[/tex]) ≈ 0.087.
Therefore, the probability that X falls between 25 and 35 hours is approximately 0.087.
In summary, the expected value of X is 20 hours. The CDF of X is F(x) = 1 - [tex]e^{-0.05x}[/tex]), and the probability that X falls between 25 and 35 hours is approximately 0.087.

You will need a calculator for this question.
Let and let Tn (x) denote the n-th Taylor polynomial approximation to f around the point x = 0. Find the minimum value of n such that the approximation Tn(1) is within 0.1 of f(1).
The answer is an integer. Write it without a decimal point.
The minimum value of n can be found by incrementally increasing the degree of the Taylor polynomial approximation until the approximation Tn(1) is within 0.1 of f(1). Starting with n = 0, we calculate Tn(1) using the Taylor polynomial formula and compare it with f(1). If the absolute difference |Tn(1) - f(1)| is less than 0.1, we have found the minimum value of n.
To find the minimum value of n such that the approximation Tn(1) is within 0.1 of f(1), we need to calculate the Taylor polynomial approximation Tn(x) and evaluate it at x = 1 until the approximation is within 0.1 of f(1).
The Taylor polynomial approximation Tn(x) for a function f(x) around the point x = 0 is given by the formula:
Tn(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ... + (f^n(0)/n!)x^n
In this case, we are interested in evaluating Tn(1), so we need to find the value of n that satisfies |Tn(1) - f(1)| < 0.1.
1. Start with n = 0 and calculate Tn(1) using the formula above.
2. Evaluate f(1) using the given function.
3. Calculate the absolute difference |Tn(1) - f(1)|.
4. If the absolute difference is less than 0.1, stop and note the value of n.
5. If the absolute difference is greater than or equal to 0.1, increment n by 1 and repeat steps 1-4.
6. Continue this process until the absolute difference is less than 0.1.
7. The minimum value of n that satisfies the condition is the final value obtained in step 4. Write this value as an integer without a decimal point.

Answer and explanation.
1. We distribute the negative sign to the -3 inside the parentheses. Thus, the answer for (1) is 3.
2. We simplify (-3)^2 - 4(1)(-10):
(-3)^2 - 4(1)(10) = 9 + 40 = 49
Thus, the answer for (2) is 49.
3. We simplify 2(1) by multiplying 2 and 1. Thus, the answer for (3) is 2.
