The local company conducted a sample survey to assess the borrowing behavior of their employees who have a 401(k) retirement plan. The national proportion of employees who borrowed against their 401(k) in the last year was 20%.

In order to determine if the local company's proportion of employees who borrowed against their 401(k) plan differs significantly from the national proportion of 20%, a hypothesis test can be performed.

The null hypothesis (H0) assumes that the local proportion is equal to the national proportion, while the alternative hypothesis (Ha) suggests that they are not equal. Using the sample data, the proportion of employees in the local company who borrowed is calculated as 24/130 ≈ 0.1846 or 18.46%.

A two-proportion z-test can be employed to compare the proportions. By comparing the test statistic (z-score) obtained from the sample data to the critical value(s) associated with the desired level of significance (e.g., 0.05), the decision can be made to either reject or fail to reject the null hypothesis.

Performing the hypothesis test will determine if the local company's proportion of employees who borrowed against their 401(k) significantly differs from the national proportion. This analysis helps the company assess whether the borrowing behavior in their organization deviates from the national trend and provides insights for potential adjustments or interventions if needed.

Step-by-step explanation:

The sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

To determine whether the sequence {an} = {\(8n^4 + n + 1\)} is convergent, we need to examine the behavior of the terms as n approaches infinity.

The sequence {an} is said to be convergent if there exists a real number L such that the terms of the sequence get arbitrarily close to L as n approaches infinity.

To investigate convergence, we can calculate the limit of the sequence as n approaches infinity.

lim(n→∞) \((8n^4 + n + 1)\)

To evaluate this limit, we can look at the highest power of n in the sequence, which is \(n^4.\) As n approaches infinity, the other terms (n and 1) become insignificant compared to n^4.

Taking the limit as n approaches infinity:

lim(n→∞) \(8n^4 + n + 1\)

= lim(n→∞) \(8n^4\)

Here, we can clearly see that the limit goes to infinity as n approaches infinity.

Therefore, the sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

The equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

To determine the solutions to the equation log₂(x - 1) = x³ - 4x, we can set the two expressions equal to each other:

log₂(x - 1) = x³ - 4x

Since we know that the graphs of the two functions intersect at the points (2, 0) and (1.1187, -3.075), we can substitute these values into the equation to find the solutions.

For the point (2, 0):

log₂(2 - 1) = 2³ - 4(2)

log₂(1) = 8 - 8

0 = 0

The equation holds true for the point (2, 0), so (2, 0) is one solution.

For the point (1.1187, -3.075):

log₂(1.1187 - 1) = (1.1187)³ - 4(1.1187)

log₂(0.1187) = 1.4013 - 4.4748

-3.075 = -3.0735 (approx.)

The equation is not satisfied for the point (1.1187, -3.075), so (1.1187, -3.075) is not a solution.

Therefore, the equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

Answer:  the required realized income before each month for your parents to afford the mortgage payment would be approximately $261,940.70.

Step-by-step explanation:

To determine the required realized income before each month for your parents, we need to calculate the remaining mortgage amount after the down payment and the interest rate. The remaining mortgage amount is the purchase price minus the down payment.

Purchase price of the house: $187,500

Down payment (20%): 0.2 * $187,500 = $37,500

Remaining mortgage amount: $187,500 - $37,500 = $150,000

Now, we can use the remaining mortgage amount, the monthly payment, and the interest rate to calculate the required realized income.

Interest rate: 4.65% (expressed as a decimal: 0.0465)

Monthly payment: $1,575

To find the required realized income, we can use the formula for the monthly payment of a mortgage:

Monthly Payment = (Loan Amount * Interest Rate) / (1 - (1 + Interest Rate)^(-Number of Payments))

In this case, we need to solve the formula for the Loan Amount, which represents the required realized income.

Loan Amount = (Monthly Payment * (1 - (1 + Interest Rate)^(-Number of Payments))) / Interest Rate

Number of Payments per year: 12 (assuming monthly payments)

Number of Payments = Number of Years * Number of Payments per year

Assuming a 30-year mortgage:

Number of Years = 30

Number of Payments = 30 * 12 = 360

Now, let's substitute the values into the formula:

Loan Amount = ($1,575 * (1 - (1 + 0.0465)^(-360))) / 0.0465

Loan Amount ≈ $261,940.70

plugging the values as in the problem

x² = 16² + 8²

x² = 320 (for SQ)

for the square, the hypotenuse is the diagonal, then using Pythagoras we have

The value of x that satisfies the equation is x = 15/8, which is equivalent to 1.875.

To solve the equation (2/3)x - (1/5)x = x - 1 and find the value of x, we can follow these steps:

Combine like terms on the left side of the equation:

(2/3 - 1/5)x = x - 1

Find a common denominator for the fractions on the left side. The common denominator for 3 and 5 is 15, so we rewrite the equation as:

(10/15 - 3/15)x = x - 1

Simplify the left side of the equation:

(7/15)x = x - 1

To eliminate the fraction, we can multiply both sides of the equation by the denominator of the fraction, which is 15:

15 * (7/15)x = 15 * (x - 1)

This simplifies to:

7x = 15x - 15

Subtract 15x from both sides of the equation to isolate the x term:

7x - 15x = -15

Simplifying further:

-8x = -15

Divide both sides of the equation by -8 to solve for x:

x = (-15) / (-8)

Simplifying the division:

x = 15/8

A scatter chart is a graphical representation of a set of observations where one variable is plotted on the x-axis and the other variable is plotted on the y-axis. Scatter charts are useful in identifying patterns and relationships between the two variables. The strength and direction of the relationship between the variables can be determined by examining the pattern of the scatter chart. If the data points are tightly clustered around a straight line, then there is a strong linear relationship between the two variables. On the other hand, if the data points are scattered without any pattern, then there is no relationship between the two variables. Scatter charts are commonly used in scientific research, marketing analysis, and other fields where two variables need to be analyzed simultaneously.
