The weight of the risk-free asset is 0.09 and the weight of the stock is 0.91.

The beta of the portfolio is 0.846.

a. The expected return on a portfolio that is equally invested in the two assets can be calculated as follows:

Expected return = (weight of stock x expected return of stock) + (weight of risk-free asset x expected return of risk-free asset)

Let's assume that the weight of both assets is 0.5:

Expected return = (0.5 x 10.5%) + (0.5 x 2.4%)

Expected return = 6.45% + 1.2%

Expected return = 7.65%

b. The portfolio weights can be calculated using the following formula:

Portfolio beta = (weight of stock x stock beta) + (weight of risk-free asset x risk-free beta)

Let's assume that the weight of the risk-free asset is w and the weight of the stock is (1-w). Also, we know that the portfolio beta is 0.92. Then we have:

0.92 = (1-w) x 1.14 + w x 0

0.92 = 1.14 - 1.14w

1.14w = 1.14 - 0.92

w = 0.09

c. The expected return-beta relationship can be represented by the following formula:

Expected return = risk-free rate + beta x (expected market return - risk-free rate)

Let's assume that the expected return of the portfolio is 9%. Then we have:

9% = 2.4% + beta x (10.5% - 2.4%)

6.6% = 7.8% beta

beta = 0.846

d. Similarly to part (b), the portfolio weights can be calculated using the following formula:

Portfolio beta = (weight of stock x stock beta) + (weight of risk-free asset x risk-free beta)

Let's assume that the weight of the risk-free asset is w and the weight of the stock is (1-w). Also, we know that the portfolio beta is 2.28. Then we have:

2.28 = (1-w) x 1.14 + w x 0

2.28 = 1.14 - 1.14w

1.14w = 1.14 - 2.28

w = -1

This is not a valid result since the weight of the risk-free asset cannot be negative. Therefore, there is no solution to this part.

To find the total number of scoops of ice cream served, we need to add the number of scoops of each flavor:

6 ¼ + 5 ¾ + 2 ¾

We can convert the mixed numbers to improper fractions to make the addition easier:

6 ¼ = 25/4

5 ¾ = 23/4

2 ¾ = 11/4

Now we can add:

25/4 + 23/4 + 11/4 = 59/4

So the ice cream parlor served 59/4 scoops of ice cream in total. We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 1:

59/4 = 14 3/4

Therefore, the parlor served 14 3/4 scoops of ice cream in total.

The Maclaurin series expansion for sin(x) is: sin(x) = x - /3! + [tex]x^5[/tex]/5! - [tex]x^7[/tex]/7!

To approximate sin(1/2) with a maximum error of 0.01, we need to find the smallest value of n for which the absolute value of the remainder term Rn(1/2) is less than 0.01.

The remainder term is given by:

Rn(x) = sin(x) - Pn(x)

where Pn(x) is the nth-degree Maclaurin polynomial for sin(x), given by:

Pn(x) = x - [tex]x^3[/tex]/3! + [tex]x^5[/tex]/5! - ... + (-1)(n+1) * x(2n-1)/(2n-1)!

Since we want the maximum error to be less than 0.01, we have:

|Rn(1/2)| ≤ 0.01

We can use the Lagrange form of the remainder term to get an upper bound for Rn(1/2):

|Rn(1/2)| ≤ |f(n+1)(c)| * |(1/2)(n+1)/(n+1)!|

where f(n+1)(c) is the (n+1)th derivative of sin(x) evaluated at some value c between 0 and 1/2.

For sin(x), the (n+1)th derivative is given by:

f^(n+1)(x) = sin(x + (n+1)π/2)

Since the derivative of sin(x) has a maximum absolute value of 1, we can bound |f(n+1)(c)| by 1:

|Rn(1/2)| ≤ (1) * |(1/2)(n+1)/(n+1)!|

We want to find the smallest value of n for which this upper bound is less than 0.01:

|(1/2)(n+1)/(n+1)!| < 0.01

We can use a table of values or a graphing calculator to find that the smallest value of n that satisfies this inequality is n = 3.

Therefore, the third-degree Maclaurin polynomial for sin(x) is:

P3(x) = x - [tex]x^3[/tex]/3! + [tex]x^5[/tex]/5!

and the approximation for sin(1/2) with a maximum error of 0.01 is:

sin(1/2) ≈ P3(1/2) = 1/2 - (1/2)/3! + (1/2)/5!

This approximation has an error given by:

|R3(1/2)| ≤ |f^(4)(c)| * |(1/2)/4!| ≤ (1) * |(1/2)/4!| ≈ 0.0024

which is less than 0.01, as required.

The probability of X being less than 14 is essentially zero. This makes sense since the mean of X is 105 and the standard deviation is likely to be quite large given that δ1^2 = ... = δ7^2.

Since X1, …, X7 are independent normal random variables with xi distributed as N(µi, δ^2) for i = 1,...,7, we can say that X ~ N(µ, δ^2), where µ = µ1 + µ2 + ... + µ7 and δ^2 = δ1^2 + δ2^2 + ... + δ7^2.

Thus, we have X ~ N(105, 7δ^2). To find p(X < 14), we need to standardize X as follows

Z = (X - µ) / δ = (14 - 105) / sqrt(7δ^2) = -91 / sqrt(7δ^2)

Now, we need to find the probability that Z is less than this value. Using a standard normal table or calculator, we get:

The probability of getting a sample mean less than 14 is approximately 0.004 when the Xi's are independent normal random variables with µ1 = … = µ7 = 15 and δ1^2 = … = δ72.

To find p(x<14), we need to standardize the distribution by subtracting the mean and dividing by the standard deviation.

Let Y = (X1 + X2 + X3 + X4 + X5 + X6 + X7)/7 be the sample mean.
Since the Xi's are independent, the mean and variance of Y are:
E(Y) = (E(X1) + E(X2) + E(X3) + E(X4) + E(X5) + E(X6) + E(X7))/7 = (µ1 + µ2 + µ3 + µ4 + µ5 + µ6 + µ7)/7 = 15
Var(Y) = Var((X1 + X2 + X3 + X4 + X5 + X6 + X7)/7) = (1/7^2) * (Var(X1) + Var(X2) + Var(X3) + Var(X4) + Var(X5) + Var(X6) + Var(X7)) = δ^2

Thus, Y ~ N(15, δ^2/7)

To standardize Y, we compute:
Z = (Y - E(Y))/sqrt(Var(Y)) = (Y - 15)/sqrt(δ^2/7)

We can then compute p(Y < 14) as:
p(Y < 14) = p(Z < (14 - 15)/sqrt(δ^2/7)) = p(Z < -sqrt(7)/δ)

Using a standard normal table, we can find that p(Z < -sqrt(7)/δ) = 0.0035, or approximately 0.004 when rounded off to two decimal places. Therefore, the probability of getting a sample mean less than 14 is approximately 0.004 when the Xi's are independent normal random variables with µ1 = … = µ7 = 15 and δ1^2 = … = δ72.

To determine how many years it will take for Tom's investment to double, we can use the compound interest formula:

A = P(1 + r/n)^(nt)

Where:

A is the final amount (double the initial investment)

P is the principal amount (initial investment)

r is the annual interest rate (9.24% or 0.0924)

n is the number of times the interest is compounded per year (monthly, so n = 12)

t is the time in years

In this case, Tom wants his investment to double, so the final amount (A) will be $8,000 * 2 = $16,000. We can plug in these values and solve for t:

$16,000 = $8,000(1 + 0.0924/12)^(12t)

Dividing both sides by $8,000:

2 = (1 + 0.0924/12)^(12t)

Taking the natural logarithm (ln) of both sides:

ln(2) = ln[(1 + 0.0924/12)^(12t)]

Using the logarithmic property ln(a^b) = b * ln(a):

ln(2) = 12t * ln(1 + 0.0924/12)

Dividing both sides by 12 * ln(1 + 0.0924/12):

t = ln(2) / (12 * ln(1 + 0.0924/12))

Using a calculator, we find:

t ≈ 9.81

Therefore, it will take approximately 9.81 years (rounding to hundredths) for Tom's investment to double.

The mass of silver that can be plated onto an object is 0.319 g.

The amount of silver plated onto the object can be calculated using Faraday's law of electrolysis, which states that the mass of a substance produced at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the cell.

The formula for calculating the mass of silver plated is:

mass of silver plated = (current x time x atomic mass of silver) / (Faraday's constant x 1000)

current = 8.70 A, time = 33.5 minutes = 2010 seconds

Atomic mass of silver (Ag) = 107.87 g/mol

Faraday's constant = 96,485 C/mol

Substituting the values in the above formula, we get:

mass of silver plated = (8.70 A x 2010 s x 107.87 g/mol) / (96,485 C/mol x 1000)

= 0.319 g

Let A be the set of positive integers less than mnmn. We want to find the probability that a randomly chosen element of A is divisible by either m or n. Let B be the set of positive integers less than mnmn that are divisible by m, and let C be the set of positive integers less than mnmn that are divisible by n.

The number of elements in B is m times the number of positive integers less than or equal to mn that are divisible by m, which is [tex]\frac{mn}{m} = n[/tex]. Thus, |B| = n. Similarly, the number of elements in C is m times the number of positive integers less than or equal to mn that are divisible by n, which is [tex]\frac{mn}{m} = n[/tex]. Thus, |C| = m.

However, we have counted the elements in B intersection C twice, since they are divisible by both m and n. The number of positive integers less than or equal to mn that are divisible by both m and n is , where lcm(m,n) denotes the least common multiple of m and n. Since m and n are co-prime, we have [tex]lcm(m,n)=mn[/tex], so the number of elements in B intersection C is [tex]\frac{mn}{mn} = 1[/tex].

Therefore, by the principle of inclusion-exclusion, the number of elements in D is:

|D| = |B| + |C| - |B intersection C| = n + m - 1 = n + m - gcd(m,n)

The probability that a randomly chosen element of A is in D is therefore:

So, Zaheda travelled by air for 3 hours. She travelled 900 km by air. (Distance travelled by the plane = 300 km/h × 3 h = 900 km)

Hence, the required answer is 3 hours and the distance Zaheda travelled by air is 900 km.

Given information: Zaheda travels for 6 hours partly by car at 100 km/h and partly by air at 300km/h. If she travelled a total distance of 1200 km we need to find out how long did she travel by air.

Solution: Let the time for which Zaheda travelled by car be t hours, then she travelled by air for (6 - t) hours. Speed of the car = 100 km/h Speed of the plane = 300 km/h Let the distance travelled by the car be 'D'. Therefore, distance travelled by the plane will be (1200 - D).

Now, we can form an equation using the speed, time, and distance using the formula, S = D/T where S = Speed, D = Distance, T = Time. Speed of the car = D/t (Using above formula) Speed of the plane = (1200 - D)/(6 - t) (Using above formula) Distance travelled by the car = Speed of the car × time= (100 × t) km Distance travelled by the plane = Speed of the plane × time = (300 × (6 - t)) km

The total distance travelled by Zaheda = Distance travelled by car + Distance travelled by plane= (100 × t) + (300 × (6 - t))= 100t + 1800 - 300t= -200t + 1800= 1200 [Given]So, -200t + 1800 = 1200 => -200t = -600 => t = 3 hours Therefore, the time for which Zaheda travelled by air = (6 - t)= 6 - 3= 3 hours. So, Zaheda travelled by air for 3 hours.

She travelled 900 km by air. (Distance travelled by the plane = 300 km/h × 3 h = 900 km)Hence, the required answer is 3 hours and the distance Zaheda travelled by air is 900 km.

This is the Taylor series for f(x) centered at c = 3.

To find the Taylor series for f(x) = 11 - x^2 centered at c = 3, we can use the formula:

f(x) = f(c) + f'(c)(x - c)/1! + f''(c)(x - c)^2/2! + f'''(c)(x - c)^3/3! + ...

First, we need to find the values of f(c), f'(c), f''(c), and f'''(c) at c = 3:

f(3) = 11 - 3^2 = 2

f'(x) = -2x

f'(3) = -2(3) = -6

f''(x) = -2

f''(3) = -2

f'''(x) = 0

f'''(3) = 0

Now we can plug these values into the formula to get the Taylor series:

f(x) = 2 - 6(x - 3) + (-2/2!)(x - 3)^2 + (0/3!)(x - 3)^3 + ...

Simplifying and continuing the pattern, we get:

f(x) = 2 - 6(x - 3) + (x - 3)^2 + ...

This is the Taylor series for f(x) centered at c = 3.

what is Taylor series?

A Taylor series is a representation of a function as an infinite sum of terms calculated from the values of the function's derivatives at a single point. In other words, the Taylor series of a function f(x) centered at x = a is given by:

f(x) = f(a) + f'(a)(x-a)/1! + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...

The first three nonzero terms of the Taylor series for f(x) = √(10x - x^2) about the point a = 5 are f(x) = 2 + (x-5) * (-1/5) + (x-5)^2 * (-3/500) + ...

The first three nonzero terms of the Taylor series for the function f(x) = √(10x - x^2) about the point a = 5 are:

f(x) = 2 + (x-5) * (-1/5) + (x-5)^2 * (-3/500) + ...

To find the Taylor series, we need to calculate the derivatives of f(x) and evaluate them at x = 5. The first three nonzero terms of the series correspond to the constant term, the linear term, and the quadratic term.

The constant term is simply the value of the function at x = 5, which is 2.

To find the linear term, we need to evaluate the derivative of f(x) at x = 5. The first derivative is:

f'(x) = (5-x) / sqrt(10x-x^2)

Evaluating this at x = 5 gives:

f'(5) = 0

Therefore, the linear term of the series is 0.

To find the quadratic term, we need to evaluate the second derivative of f(x) at x = 5. The second derivative is:

f''(x) = -5 / (10x-x^2)^(3/2)

Evaluating this at x = 5 gives:

f''(5) = -1/5

Therefore, the quadratic term of the series is (x-5)^2 * (-3/500).

Thus, the first three nonzero terms of the Taylor series for f(x) = √(10x - x^2) about the point a = 5 are:

f(x) = 2 + (x-5) * (-1/5) + (x-5)^2 * (-3/500) + ...

The statement is True.

The theorem of linear algebra that states that if a and b are invertible matrices, then the product ab is invertible is indeed true.

Proof:

Let A and B be invertible matrices.

Then there exist matrices A^-1 and B^-1 such that AA^-1 = I and BB^-1 = I, where I is the identity matrix.

We want to show that AB is invertible, that is, we want to find a matrix (AB)^-1 such that (AB)(AB)^-1 = (AB)^-1(AB) = I.

Using the associative property of matrix multiplication, we have:

(AB)(A^-1B^-1) = A(BB^-1)B^-1 = AIB^-1 = AB^-1

So (AB)(A^-1B^-1) = AB^-1.

Multiplying both sides on the left by (AB)^-1 and on the right by (A^-1B^-1)^-1 = BA, we get:

(AB)^-1 = (A^-1B^-1)^-1BA = BA^-1B^-1A^-1.

Therefore, (AB)^-1 exists, and it is equal to BA^-1B^-1A^-1.

Hence, we have shown that if A and B are invertible matrices, then AB is invertible.

The maximum concentration occurs at time t = 50 minutes.

To find the maximum concentration, we need to find the maximum value of the concentration function c(t). We can do this by finding the critical points of c(t) and determining whether they correspond to a maximum or a minimum.

First, we find the derivative of c(t):

c'(t) = 20e^(-0.02t) - 0.4te^(-0.02t)

Next, we set c'(t) equal to zero and solve for t:

20e^(-0.02t) - 0.4te^(-0.02t) = 0

Factor out e^(-0.02t):

e^(-0.02t)(20 - 0.4t) = 0

So either e^(-0.02t) = 0 (which is impossible), or 20 - 0.4t = 0.

Solving for t, we get:

t = 50

So, the maximum concentration occurs at time t = 50 minutes.

Therefore, the minimum value of y is approximately 0 and the maximum value of y is approximately 1.93.

To find the minimum and maximum values of the given function y=√14θ−√7secθ on the interval [0, π/3], we need to find the critical points and endpoints of the function in the given interval.

First, we take the derivative of the function with respect to θ:

y' = (1/2)√14 - (√7/2)secθ tanθ

Setting y' equal to zero, we get:

(1/2)√14 - (√7/2)secθ tanθ = 0

tanθ = (1/2)√14/√7 = 1/√2

θ = π/8 or θ = 5π/8

Note that θ = 5π/8 is not in the interval [0, π/3], so we only need to consider θ = π/8.

Next, we evaluate the function at the critical point and the endpoints of the interval:

y(0) = √14(0) - √7sec(0) = 0

y(π/3) = √14(π/3) - √7sec(π/3) ≈ 1.93

y(π/8) = √14(π/8) - √7sec(π/8) ≈ 1.46
