To determine the value of k in the function f(x) = [tex]x^4[/tex] + k[tex]x^3[/tex] - 3x - 5, we can consider the remainders when f(x) is divided by (x-3) and (x+3).

a) When f(x) is divided by (x-3), the remainder is -10. To find the remainder, we can use the Remainder Theorem, which states that if a polynomial f(x) is divided by (x - a), the remainder is equal to f(a). Plugging in x = 3 into f(x), we get:

f(3) = [tex]3^4[/tex] + k([tex]3^3[/tex]) - 3(3) - 5

     = 81 + 27k - 9 - 5

     = 27k + 67

Since the remainder is -10, we can set up the equation:

27k + 67 = -10

Solving this equation, we find:

27k = -77

k = -77/27

b) To determine the remainder when f(x) is divided by (x+3), we can follow a similar process. Plugging in x = -3 into f(x), we get:

f(-3) =[tex](-3)^4[/tex] + k[tex](-3)^3[/tex] - 3(-3) - 5

       = 81 - 27k + 9 - 5

       = -27k + 85

The remainder is given by f(-3), so we can set up the equation:

-27k + 85 = remainder

Hence, the remainder when f(x) is divided by (x+3) is -27k + 85.

In summary, the value of k such that the remainder when f(x) is divided by (x-3) is -10 is k = -77/27. Additionally, the remainder when f(x) is divided by (x+3) is -27k + 85.

The probability that sample A will have mean of 90.7 more than sample B is 0.0475. Therefore the correct answer is (D)

Given:

- Population A: meanA = 100, sigmaA = 45

- Population B: meanB = 30, sigmaB = 14

- Sample sizes for both samples: n = 15

We want to find the probability that the sample mean of sample A will be 90.7 or more than the sample mean of sample B.

To find this probability, we need to calculate the standard deviation of the sampling distribution of the difference in sample means. The standard deviation of the difference in sample means (denoted as sigma difference) is calculated as follows:

sigma difference = [tex]\sqrt{(\frac{sigmaA^2}{nA}) + (\frac{sigmaB^2}{nB})}[/tex]

Where:

- sigmaA = standard deviation of population A

- sigmaB = standard deviation of population B

- nA = sample size for sample A

- nB = sample size for sample B

In this case, both samples have the same size, nA = nB = 15.

sigma difference = [tex]\sqrt{(\frac{45^2}{15}) + (\frac{14^2}{15})}[/tex]

sigma difference = [tex]\sqrt{(\frac{2025}{15}) + (\frac{196}{15})}[/tex]

sigma difference = [tex]\sqrt{(135+ 13.07)}[/tex]

sigma difference = [tex]\sqrt{(148.7)}[/tex]

sigma difference = 12.16

Now, we can calculate the z-score, which is the difference between the desired sample mean difference and the population mean difference (mu difference = meanA - meanB), divided by the standard deviation of the sampling distribution (sigma difference).

z = (90.7 - (meanA - meanB)) / sigma difference

z = (90.7 - (100 - 30)) / 12.16

z = (90.7 - 70) / 12.16

z ≈ 1.69

To find the probability that the sample mean difference is 90.7 or more, we need to calculate the area under the standard normal curve to the right of the z-score (1.69).

Using a standard normal distribution table or a calculator, we find that the probability is approximately 0.9525.

However, we want the probability that the sample mean of sample A is 90.7 or more than the sample mean of sample B, which means we need to find the probability to the left of the z-score (-1.69) and then subtract it from 1.

P(z < -1.69) = 1 - P(z > -1.69)

Using a standard normal distribution table or a calculator, we find that P(z > -1.69) is approximately 0.9525.

Therefore, the probability that the sample mean of sample A will be 90.7 or more than the sample mean of sample B is:

P(z < -1.69) = 1 - P(z > -1.69) = 1 - 0.9525 ≈ 0.0475

The closest option is D. 0.0445, but the calculated probability is approximately 0.0475.

One distinction between a population parameter and a sample statistic is that the former describes a characteristic of an entire population, while the latter is characteristic of a subset of the population, called a sample.

In statistics, a population parameter is a numerical value that describes a characteristic of an entire population. It is a fixed value and is usually unknown or difficult to determine precisely. Population parameters are typically denoted by Greek letters (e.g., [tex]\mu[/tex] for the population means, σ for the population standard deviation).

On the other hand, a sample statistic is a numerical value that represents a characteristic of a sample, which is a subset of the population. Sample statistics are used to estimate population parameters. Since a sample is a smaller portion of the entire population, sample statistics can vary from one sample to another. Sample statistics are typically denoted by Latin letters (e.g., [tex]\bar{x}[/tex]  for the sample mean, s for the sample standard deviation).

The distinction lies in the scope of the information they provide. Population parameters aim to describe the overall characteristics of a population, while sample statistics provide information about a specific subset of the population, which can be used to infer or estimate the population parameters.

An increase in the real interest rate will most likely lower the reward to savings. The correct answer is D.

When the real interest rate increases, it means that the return on savings and investments is higher in real terms, adjusted for inflation. As a result, individuals are incentivized to save more as they can earn a higher return on their savings.

When the reward to savings is lower, it becomes less attractive for individuals to save. Higher interest rates can discourage borrowing and encourage saving, which reduces consumer spending on durable goods and other discretionary purchases.

Option A is incorrect because an increase in the real interest rate would likely lead to a decrease in consumer's purchases of durable goods, as higher interest rates increase the cost of borrowing, making it more expensive to finance large purchases.

Option B is incorrect because an increase in the real interest rate generally makes borrowing more expensive, as it increases the cost of borrowing for individuals and businesses.

Option C is incorrect because an increase in the real interest rate usually encourages individuals to save more and spend less, as the potential return on savings is higher.

The correct answer is D.

The equation h(x) = 2x - 0 = x - 10 is satisfied by the value x = -10; the omitted integer is 10.

A function is a mathematical formula that illustrates the relationship between the dependent and independent variables. The independent variable's value and the dependent variable's value both change in the function.

Determine x in terms of f(x) in order to determine the inverse of the function f(x) = x + 10:

f(x) = x + 10

f(x) - 10 = x

x = f(x) - 10

Since h(x) is the opposite of f(x), replace x with h(x):

h(x) = f⁻¹(x) = x - 10

Since h(x) is the opposite of f(x), replace x with h(x):

To identify the missing value, compare the expression for h(x) to the supplied function, h(x) = 2x-0. We can see that the appropriate expression for h(x) is:

h(x) = 2x - 0 = x - 10

Find the value of x that allows this equation to be solved:

2x - 0 = x - 10

Simplifying and solving for x,

x = -10

Therefore, the missing value is O 10, since x = -10 satisfies the equation h(x) = 2x - 0 = x - 10

The data set represent a population.

The range for this data set is 9.

The variance for this data set is 14.05.

The standard deviation for this data set is 3.748.

In Statistics, a population simply refers to a set of similar items or events that comprises every member of a group i.e the total number of elements.

Based on the given data set, we would calculate the range by using the following formula:

Range = Highest number - Lowest number

Range = 24 - 15

Range = 9.

Next, we would determine the mean as follows;

Mean = ∑fx/n

Mean = (24 + 16 +23+22+17+15+24+24+24+16)/10

Mean = 205/10 = 20.5

Now, we can calculate the standard deviation and variance by using this formula:

Standard deviation, δ = √(1/n × ∑(xi - μ)²)

Standard deviation, δ = √[1/10 × (24 - 20.5)² + (16 - 20.5)² + (23 - 20.5)² + (22 - 20.5)² + (17 - 20.5)² + (15 - 20.5)² + (24 - 20.5)² + (24 - 20.5)² + (24 - 20.5)² + (16 - 20.5)²]

Standard deviation, δ = √140.5/10

Standard deviation, δ = 3.748.

For the variance, we have:

Variance = δ²

Variance = 3.75²

Variance = 14.05

For every divisor d of the order n of a cyclic group G=⟨a⟩, there exists a subgroup of G whose order is d.

To approach this, we can consider the properties of cyclic groups. A cyclic group G generated by a single element "a" has elements that are powers of "a" in the form of [tex]a^k[/tex], where k takes values from 0 to n-1. The order of an element "a" in G is the smallest positive integer k such that [tex]a^k[/tex] equals the identity element.

Now, let's focus on the divisors of n. Each divisor d divides n evenly, meaning n/d is an integer. We can consider the element "[tex]a^(^n^/^d^)[/tex]" in G. The order of "[tex]a^(^n^/^d^)[/tex]" is d because [tex](a^(^n^/^d^))^d = a^n = e[/tex], where e is the identity element of G.

Hence, the subgroup generated by "[tex]a^(^n^/^d^)[/tex]" has an order of d, since it consists of elements of the form [tex](a^(^n^/^d^))^k[/tex], where k takes values from 0 to d-1. Therefore, for every divisor d of n, there exists a subgroup of G whose order is d.

This demonstrates the relationship between the divisors of n and the order of the subgroups in the cyclic group G.

Step-by-step explanation:

The amount in the account after 26 years is approximately $37,120.06.

To calculate the amount of money in an account after a given number of years, you can use the formula for compound interest.

The formula for compound interest is given as follows:

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

A is the amount of money in the account after t years.

P is the principal amount.

r is the annual interest rate.

n is the number of times the interest is compounded per year.

t is the number of years 6900 dollars is placed in an account with an annual interest rate of 8.25%.

To find out how much will be in the account after 26 years, we will use the formula for compound interest by applying the given values:

P = 6900 dollars

r = 8.25%n = 1 (as the interest is compounded annually)

t = 26 years

Substituting the values in the formula, we get:

A = 6900(1 + 0.0825/1)^(1*26)

Using a calculator, we get:

A ≈ $37,120.06

Therefore, the amount in the account after 26 years is approximately $37,120.06.
