If f is a one-to-one function such that f(2)=-6 , what is f^{-1}(-6) ?

P{X ≤ x} = P{B ≥ 3} where B has a Binom (5, x) distribution. An explicit polynomial expression for the cumulative distribution function F X(x) is given by FX(x) = 10x3(1 − x)2 + 5x4(1 − x) + x5 .The probability density function fX(x) is given by

fX(x) = 30x2(1 − x)2 − 20x3(1 − x) + 5x4. P{0.25 ≤ X ≤ 0.75} = 0.324.

(a) P{X ≤ x} = P{B ≥ 3} where B has a Binom (5, x) distribution is given as follows: For x between 0 and 1, let B = number of U's that are less than or equal to x. Then, B has a Binom (5, x) distribution. Hence, P{B ≥ 3} can be calculated from the Binomial tables (or from R with p binom (2, 5, x, lower.tail = FALSE)). Also, X ≤ x if and only if at least three of the U's are less than or equal to x.

Therefore, [tex]P{X ≤ x} = P{B ≥ 3}.[/tex]Hence, [tex]P{X ≤ x} = P{B ≥ 3}[/tex]where B has a Binom (5, x) distribution(b) To write down an explicit polynomial expression for the cumulative distribution function FX(x), we have to use the relationship [tex]P{X ≤ x} = P{B ≥ 3}.[/tex]

For this, we use the fact that if B has a Binom (n,p) distribution, then  P{B = k} = (nCk)(p^k)(1-p)^(n-k), where nCk is the number of combinations of n things taken k at a time.

We see that

P{B = 0} = (5C0)(x^0)(1-x)^(5-0) = (1-x)^5,P{B = 1} = (5C1)(x^1)(1-x)^(5-1) = 5x(1-x)^4,P{B = 2} = (5C2)(x^2)(1-x)^(5-2) = 10x^2(1-x)^3,

P{B = 3} = (5C3)(x^3)(1-x)^(5-3) = 10x^3(1-x)^2,P{B = 4} = (5C4)(x^4)(1-x)^(5-4) = 5x^4(1-x),P{B = 5} = (5C5)(x^5)(1-x)^(5-5) = x^5

Hence, using the relationship  P{X ≤ x} = P{B ≥ 3},

we have For x between 0 and 1,

FX(x) = P{X ≤ x} = P{B ≥ 3} = P{B = 3} + P{B = 4} + P{B = 5} = 10x^3(1-x)^2 + 5x^4(1-x) + x^5 .

To find the probability  P{0.25 ≤ X ≤ 0.75},

we will use the relationship P{X ≤ x} = P{B ≥ 3} and the expression for the cumulative distribution function that we have derived in part .

Then, P{0.25 ≤ X ≤ 0.75} can be calculated as follows:

P{0.25 ≤ X ≤ 0.75} = FX(0.75) − FX(0.25) = [10(0.75)^3(1 − 0.75)^2 + 5(0.75)^4(1 − 0.75) + (0.75)^5] − [10(0.25)^3(1 − 0.25)^2 + 5(0.25)^4(1 − 0.25) + (0.25)^5] = 0.324.

To find the probability density function fX(x), we differentiate the cumulative distribution function derived in part .

We get fX(x) = FX'(x) = d/dx[10x^3(1-x)^2 + 5x^4(1-x) + x^5] = 30x^2(1-x)^2 − 20x^3(1-x) + 5x^4 .The  answer is given as follows:

P{X ≤ x} = P{B ≥ 3} where B has a Binom (5, x) distribution. An explicit polynomial expression for the cumulative distribution function F X(x) is given by FX(x) = 10x3(1 − x)2 + 5x4(1 − x) + x5 . P{0.25 ≤ X ≤ 0.75} = 0.324.

The probability density function fX(x) is given by

fX(x) = 30x2(1 − x)2 − 20x3(1 − x) + 5x4.

1400 + 400(x-3), if x > 3

The function C(x) is a piecewise function because it is defined differently for x <= 3 and x > 3. For the first three days, the cost is a flat rate of Php 1,000.

The joint PDF of X2 and X3 is constant within the region 0 < X2 < 1 and 0 < X3 < 1, and zero elsewhere.

To compute the sampling distribution of X2 and X3, we need to find the joint probability density function (PDF) of these two random variables.

Since X1, X2, and Xn are uniformly distributed on the interval (0, 1), their joint PDF is given by:

f(x1, x2, ..., xn) = 1, if 0 < xi < 1 for all i, and 0 otherwise

To find the joint PDF of X2 and X3, we need to integrate this joint PDF over all possible values of X1 and X4 through Xn. Since X1 does not appear in the joint PDF of X2 and X3, we can integrate it out as follows:

f(x2, x3) = ∫∫ f(x1, x2, x3, x4, ..., xn) dx1dx4...dxn

= ∫∫ 1 dx1dx4...dxn

= ∫0¹ ∫0¹ 1 dx1dx4

= 1

Therefore, the joint PDF of X2 and X3 is constant within the region 0 < X2 < 1 and 0 < X3 < 1, and zero elsewhere. This implies that X2 and X3 are independent and identically distributed (i.i.d.) random variables with a uniform distribution on (0, 1).

In other words, the sampling distribution of X2 and X3 is also a uniform distribution on the interval (0, 1).

(b) The solution to the differential equation is y = ((x^2 - 2x + 2)e^x + C)/x^3, where C is a constant.

(a) To solve the differential equation y' + (1/x)y = 3cos(2x), we can use the method of integrating factors. The integrating factor is given by μ(x) = e^(∫(1/x)dx) = e^(ln|x|) = |x|. Multiplying both sides of the equation by |x|, we have |x|y' + y = 3xcos(2x). Now, we can rewrite the left side as (|x|y)' = 3xcos(2x). Integrating both sides with respect to x, we get |x|y = ∫(3xcos(2x))dx. Evaluating the integral and simplifying, we obtain |x|y = (3/2)sin(2x) + C, where C is the constant of integration. Dividing both sides by |x|, we finally have y = (3/2)(sin(2x)/|x|) + C/|x|.

(b) To solve the differential equation xy' + 2y = e^x, we can use the method of integrating factors. The integrating factor is given by μ(x) = e^(∫(2/x)dx) = e^(2ln|x|) = |x|^2. Multiplying both sides of the equation by |x|^2, we have x^3y' + 2x^2y = x^2e^x. Now, we can rewrite the left side as (x^3y)' = x^2e^x. Integrating both sides with respect to x, we get x^3y = ∫(x^2e^x)dx. Evaluating the integral and simplifying, we obtain x^3y = (x^2 - 2x + 2)e^x + C, where C is the constant of integration. Dividing both sides by x^3, we finally have y = ((x^2 - 2x + 2)e^x + C)/x^3.

The quotient is 3x^2 - x - 2.

To use synthetic division to find the quotient of (3x^3 - 7x^2 + 2x + 1) divided by (x - 2), we set up the synthetic division table as follows:

Copy code

  |   3    -7     2     1

2 |_____________________

First, we write down the coefficients of the dividend (3x^3 - 7x^2 + 2x + 1) in descending order: 3, -7, 2, 1. Then, we bring down the first coefficient, 3, as the first value in the second row.

Next, we multiply the divisor, 2, by the number in the second row and write the result below the next coefficient. Multiply: 2 * 3 = 6.

Copy code

  |   3    -7     2     1

2 | 6

Add the result, 6, to the next coefficient in the first row: -7 + 6 = -1. Write this value in the second row.

Copy code

  |   3    -7     2     1

2 | 6 -1

Again, multiply the divisor, 2, by the number in the second row and write the result below the next coefficient: 2 * (-1) = -2.

Copy code

  |   3    -7     2     1

2 | 6 -1 -2

Add the result, -2, to the next coefficient in the first row: 2 + (-2) = 0. Write this value in the second row.

Copy code

  |   3    -7     2     1

2 | 6 -1 -2 0

The bottom row represents the coefficients of the resulting polynomial after the synthetic division. The first value, 6, is the coefficient of x^2, the second value, -1, is the coefficient of x, and the third value, -2, is the constant term.

Thus, the quotient of (3x^3 - 7x^2 + 2x + 1) divided by (x - 2) is:

3x^2 - x - 2

a) This estimator estimates the slope of the linear relationship between x and y, even if β₀ is known.

(a) In the given scenario where β₀ is known and does not need to be estimated, the least squares estimator for β₁ remains the same as in the standard simple linear regression model. The least squares estimator for β₁ is calculated using the formula:

beta₁ = Σ((xᵢ - x(bar))(yᵢ - y(bar))) / Σ((xᵢ - x(bar))²)

where xᵢ is the observed value of the independent variable, x(bar) is the mean of the independent variable, yᵢ is the observed value of the dependent variable, and y(bar) is the mean of the dependent variable.

(b) The variance of the least squares estimator beta₁ can be calculated using the formula:

Var(beta₁) = σ² / Σ((xᵢ - x(bar))²)

where σ² is the variance of the error term ε.

(c) To find a 100(1−α)% confidence interval for β₁, we can use the standard formula:

beta₁ ± tₐ/₂ * SE(beta₁)

where tₐ/₂ is the critical value from the t-distribution with (n-2) degrees of freedom, and SE(beta₁) is the standard error of the estimator beta₁.

The confidence interval obtained in this scenario, where β₀ is known, should have the same width as the confidence interval when both β₀ and β₁ are unknown and need to be estimated. The only difference is that the point estimate for β₁ will be the same as the true value of β₁, which is known in this case.

Given that Y has a lognormal distribution with mean μ = 71.2 and variance σ² = 158.40.

The mean and variance of lognormal distribution are given by: E(Y) = exp(μ + σ²/2) and V(Y) = [exp(σ²) - 1]exp(2μ + σ²)

If you perform a test and get a p-value = 0.051 you should not reject the null hypothesis. The statement given in the question is False.

A p-value is a measure of statistical significance, and it is used to evaluate the likelihood of a null hypothesis being true. If the p-value is less than or equal to the significance level, the null hypothesis is rejected. However, if the p-value is greater than the significance level, the null hypothesis is accepted, which means that the results are not statistically significant and can occur due to chance alone. A p-value is a measure of the evidence against the null hypothesis. The smaller the p-value, the stronger the evidence against the null hypothesis. On the other hand, a larger p-value indicates that the evidence against the null hypothesis is weaker. A p-value less than 0.05 is considered statistically significant.

There were 38 heavy equipment operators and 2 general laborers employed.

To calculate the number of heavy equipment operators, let's assume the number of heavy equipment operators as "x" and the number of general laborers as "y."

The cost of hiring a heavy equipment operator per day is $120, and the cost of hiring a general laborer per day is $93.

We can set up two equations based on the given information:

Equation 1: x + y = 40 (since a total of 40 people were hired)

Equation 2: 120x + 93y = 4746 (since the total payroll was $4746)

To solve these equations, we can use the substitution method.

From Equation 1, we can solve for y:

y = 40 - x

Substituting this into Equation 2:

120x + 93(40 - x) = 4746

120x + 3720 - 93x = 4746

27x = 1026

x = 38

Substituting the value of x back into Equation 1, we can find y:

(a) The number of workers in the sample who are union members can be estimated by taking the expected value of the relevant random variable. In this case, the random variable represents the number of union members in a sample of 20 workers.

Since 96% of all workers belong to the union, we can expect that 96% of the workers in the sample will also be union members. Therefore, the expected value of the random variable is given by:

E(X) = np

where n is the sample size (20) and p is the probability of success (0.96).

E(X) = 20 * 0.96 = 19.2

Therefore, the mean of the relevant distribution is 19.2.

(b) To quantify the uncertainty of the estimate, we can calculate the standard deviation of the distribution. For a binomial distribution, the standard deviation is given by:

σ = sqrt(np(1-p))

Using the same values as above, we can calculate the standard deviation:

σ = sqrt(20 * 0.96 * (1 - 0.96))

The function that maps each polynomial in S to its derivative is not one-to-one.

To show that it is not one-to-one, we need to demonstrate that there exist two different polynomials in S that map to the same derivative. Consider two polynomials in S: f(x) = x^2 and g(x) = x^2 + 1. The derivatives of both f(x) and g(x) are equal to 2x. Therefore, the function maps both f(x) and g(x) to the same derivative, indicating that it is not one-to-one.

On the other hand, the function is onto. This means that for any polynomial in T (which is a set of polynomials with real coefficients), there exists at least one polynomial in S that maps to it. In this case, for any polynomial g(x) in T, we can find a polynomial f(x) in S such that f'(x) = g(x). We can choose f(x) to be the antiderivative of g(x), which exists since g(x) is a polynomial.

a. The function for Above the Bored's monthly profit is P(x) = $226x.

b. Above the Bored will have a net profit of $39,098.

c. Above the Bored needs to sell a minimum of 1 wakeboard in a month to break even.

(a) To find the function P(x) for Above the Bored's monthly profit, we need to subtract the cost of producing x wakeboards from the revenue generated by selling x wakeboards.

Revenue = Selling price per wakeboard * Number of wakeboards sold

Revenue = $480 * x

Cost = Cost per wakeboard * Number of wakeboards produced

Cost = $254 * x

Profit = Revenue - Cost

P(x) = $480x - $254x

P(x) = $226x

Therefore, the function for Above the Bored's monthly profit is P(x) = $226x.

(b) If Above the Bored produces and sells 173 wakeboards in a month, we can substitute x = 173 into the profit function to find the net profit:

P(173) = $226 * 173

P(173) = $39,098

Therefore, for that month, Above the Bored will have a net profit of $39,098.

(c) To break even, Above the Bored needs to have a profit of $0. In other words, the revenue generated must equal the cost incurred.

Setting P(x) = 0, we can solve for x:

$226x = 0

x = 0

Since the number of wakeboards cannot be zero (as it is not possible to sell no wakeboards), the minimum number of wakeboards Above the Bored needs to sell in a month to break even is 1.

Therefore, Above the Bored needs to sell a minimum of 1 wakeboard in a month to break even.

x + y = 350 (equation 1, since the vendor has a total of 350 shirts)

12x + 16y = 5000 (equation 2, since the total revenue from selling x short sleeve shirts and y long sleeve shirts is $5000)

We can use equation 1 to solve for y in terms of x:

y = 350 - x

Substituting this into equation 2, we get:

12x + 16(350 - x) = 5000

Simplifying and solving for x, we get:

The probability that the machine will function between 50 and 150 hours without a major breakdown is 0.3736.

The probability that it will work another extra 20 hours properly is 0.0648.

To solve these questions, we can use the properties of the exponential distribution. The exponential distribution is often used to model the time between events in a Poisson process, such as the time between major breakdowns of a machine in this case.

For an exponential distribution with a mean value of λ, the probability density function (PDF) is given by:

f(x) = λ * e^(-λx)

where x is the time, and e is the base of the natural logarithm.

The cumulative distribution function (CDF) for the exponential distribution is:

F(x) = 1 - e^(-λx)

Q7) To find this probability, we need to calculate the difference between the CDF values at 150 hours and 50 hours.

Let λ be the rate parameter, which is equal to 1/mean. In this case, λ = 1/100 = 0.01.

P(50 ≤ X ≤ 150) = F(150) - F(50)

= (1 - e^(-0.01 * 150)) - (1 - e^(-0.01 * 50))

= e^(-0.01 * 50) - e^(-0.01 * 150)

≈ 0.3935 - 0.0199

Q8) In this case, we need to calculate the probability that the machine functions between 100 and 120 hours without a major breakdown.

P(100 ≤ X ≤ 120) = F(120) - F(100)

= (1 - e^(-0.01 * 120)) - (1 - e^(-0.01 * 100))

To find the area between the x-axis and the function f(x) as x goes from 0 to 3, we can integrate the absolute value of f(x) over that interval. The absolute value of f(x) is |[tex]e^x + 1[/tex]|. To find the area, we can integrate |[tex]e^x + 1[/tex]| from x = 0 to x = 3:

Area = ∫[0, 3] |[tex]e^x + 1[/tex]| dx

Since [tex]e^x + 1[/tex] is positive for all x, we can simplify the absolute value:

Area = ∫[0, 3] [tex](e^x + 1) dx[/tex]

Integrating this function over the interval [0, 3], we have:

Area = [tex][e^x + x][/tex] evaluated from 0 to 3

[tex]= (e^3 + 3) - (e^0 + 0)\\= e^3 + 3 - 1\\= e^3 + 2\\[/tex]

The algorithm progresses and the K values decrease, the sublists become more sorted, leading to a final sorted list.

To sort the list {4, 9, 2, 5, 3, 10, 8, 1, 6, 7} using Shell sort, we will use the K values as N/2, N/4, ..., 1, where N is the size of the list.

Here are the steps and contents after each round of K:

Initial list: {4, 9, 2, 5, 3, 10, 8, 1, 6, 7}

Step 1 (K = N/2 = 10/2 = 5):

Splitting the list into 5 sublists:

Sublist 1: {4, 10}

Sublist 2: {9}

Sublist 3: {2, 8}

Sublist 4: {5, 1}

Sublist 5: {3, 6, 7}

Sorting each sublist:

Sublist 1: {4, 10}

Sublist 2: {9}

Sublist 3: {2, 8}

Sublist 4: {1, 5}

Sublist 5: {3, 6, 7}

Contents after K = 5: {4, 10, 9, 2, 8, 1, 5, 3, 6, 7}

Step 2 (K = N/4 = 10/4 = 2):

Splitting the list into 2 sublists:

Sublist 1: {4, 9, 8, 5, 6}

Sublist 2: {10, 2, 1, 3, 7}

Sorting each sublist:

Sublist 1: {4, 5, 6, 8, 9}

Sublist 2: {1, 2, 3, 7, 10}

Contents after K = 2: {4, 5, 6, 8, 9, 1, 2, 3, 7, 10}

Step 3 (K = N/8 = 10/8 = 1):

Splitting the list into 1 sublist:

Sublist: {4, 5, 6, 8, 9, 1, 2, 3, 7, 10}

Sorting the sublist:

Sublist: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Contents after K = 1: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

After the final step, the list is sorted in increasing order: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

Note: Shell sort is an in-place comparison-based sorting algorithm that uses a diminishing increment sequence (in this case, K values) to sort the elements. The algorithm repeatedly divides the list into smaller sublists and sorts them using an insertion sort. As the algorithm progresses and the K values decrease, the sublists become more sorted, leading to a final sorted list.

The required corresponding formula for the measure of the union

of n sets is μ(A₁ ∪ A₂ ∪ ... ∪ Aₙ) = ∑ μ(Aᵢ) - ∑ μ(Aᵢ ∩ Aⱼ) + ∑ μ(Aᵢ ∩ Aⱼ ∩ Aₖ) - ... + (-1)^(n+1) μ(A₁ ∩ A₂ ∩ ... ∩ Aₙ)

The measure of the union of n sets, denoted as μ(A₁ ∪ A₂ ∪ ... ∪ Aₙ), can be computed using the inclusion-exclusion principle. The formula for the measure of the union of n sets is given by:

μ(A₁ ∪ A₂ ∪ ... ∪ Aₙ) = ∑ μ(Aᵢ) - ∑ μ(Aᵢ ∩ Aⱼ) + ∑ μ(Aᵢ ∩ Aⱼ ∩ Aₖ) - ... + (-1)^(n+1) μ(A₁ ∩ A₂ ∩ ... ∩ Aₙ)

This formula accounts for the overlapping regions between the sets to avoid double-counting and ensures that the measure is computed correctly.

To prove the formula, we can use mathematical induction. The base case for n = 2 can be established using the definition of the measure. For the inductive step, assume the formula holds for n sets, and consider the union of n+1 sets:

μ(A₁ ∪ A₂ ∪ ... ∪ Aₙ₊₁)

Using the formula for the union of two sets, we can rewrite this as:

μ((A₁ ∪ A₂ ∪ ... ∪ Aₙ) ∪ Aₙ₊₁)

By the induction hypothesis, we know that:

μ(A₁ ∪ A₂ ∪ ... ∪ Aₙ) = ∑ μ(Aᵢ) - ∑ μ(Aᵢ ∩ Aⱼ) + ∑ μ(Aᵢ ∩ Aⱼ ∩ Aₖ) - ... + (-1)^(n+1) μ(A₁ ∩ A₂ ∩ ... ∩ Aₙ)

Using the inclusion-exclusion principle, we can expand the above expression to include the measure of the intersection of each set with Aₙ₊₁:

∑ μ(Aᵢ) - ∑ μ(Aᵢ ∩ Aⱼ) + ∑ μ(Aᵢ ∩ Aⱼ ∩ Aₖ) - ... + (-1)^(n+1) μ(A₁ ∩ A₂ ∩ ... ∩ Aₙ) + μ(A₁ ∩ Aₙ₊₁) - μ(A₂ ∩ Aₙ₊₁) + μ(A₁ ∩ A₂ ∩ Aₙ₊₁) - ...

Simplifying this expression, we obtain the formula for the measure of the union of n+1 sets. Thus, by mathematical induction, we have proven the corresponding formula for the measure of the union of n sets.

Calculating this expression will give us the probability that a person's Badger 5 lottery ticket will have exactly two winning numbers.

To find the probability of a person's Badger 5 lottery ticket having exactly two winning numbers, we need to determine the total number of possible outcomes and the number of favorable outcomes.

The total number of possible outcomes in the Badger 5 game is given by the number of ways to choose 5 numbers out of 31 without repetition and in numerical order.

The number of favorable outcomes is the number of ways to choose exactly two winning numbers out of the 5 numbers drawn in the lottery drawing.

To calculate these values, we can use the binomial coefficient formula:

nCr = n! / (r! * (n-r)!)

where n is the total number of available numbers (31 in this case) and r is the number of numbers to be chosen (5 in this case).

The probability of exactly two winning numbers can be calculated as:

P(exactly two winning numbers) = (number of favorable outcomes) / (total number of possible outcomes)

Substituting the values into the formula, we can calculate the probability:

P(exactly two winning numbers) = (5C2 * 26C3) / (31C5)

Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100%

To determine the system capacity and the bottleneck stage and utilization of Stage 3:

The system capacity is calculated by the product of the processing capacity of each stage:

1 x 1 x 2 = 2 units per minute

The bottleneck stage is the stage with the lowest capacity and it is Stage A. Therefore, Stage A has the lowest capacity and determines the system capacity.The utilization of Stage 3 can be calculated as the processing time per unit divided by the available time per unit:

Process time per unit = 1 + 2 + 3 = 6 minutes per unit

Available time per unit = 90% x 100% x 100% = 0.9 x 1 x 1 = 0.9 minutes per unit

The utilization of Stage 3 is, therefore, (6/0.9) x 100% = 666.67%.

However, utilization cannot be greater than 100%, so the actual utilization of Stage 3 is 100%.
