To construct a truth table, we need to list all possible combinations of truth values for p and q, and then evaluate the truth value of each statement for each combination. The columns of the table represent the truth values of p and q, and the rows represent the different parts of each statement being evaluated. Here is the truth table:

p | q | q -> p | p -> q

------------------------

T | T |   T    |   T

T | F |   T    |   F

F | T |   F    |   T

F | F |   T    |   T

From the truth table, we can see that the two statements are not equivalent, since they have different truth values for the second row (where p is true and q is false). Therefore, the answer is (b) False.

A bank asks customers to evaluate its drive-through service as good, average, or poor. The answer to the given question is ordinal. The level of measurement in which the data is categorized and ranked with respect to each other is called the ordinal level of measurement.

The nominal level of measurement is used to categorize data, but this level of measurement does not have an inherent order to the categories. The interval level of measurement is used to measure the distance between two different variables but does not have an inherent zero point. The ratio level of measurement, on the other hand, is used to measure the distance between two different variables and has an inherent zero point.

The customers are asked to rate the drive-through service as either good, average, or poor. This is an example of the ordinal level of measurement because the data is categorized and ranked with respect to each other. While the categories have an order to them, they do not have an inherent distance between each other.The ordinal level of measurement is useful in many different fields. customer satisfaction surveys often use ordinal data to gather information on how satisfied customers are with the service they received. Additionally, academic researchers may use ordinal data to rank different study participants based on their performance on a given task. Overall, the ordinal level of measurement is a valuable tool for researchers and others who need to categorize and rank data.

Correct option is

Options A, B and D are equations of lines. We prove that the points in option B don't lie on a line. Consider the line passing through first two points. Its equation is 

2−12y−12=0−(−4)x−(−4)

⟹−10y−12=4x+4

⟹2y−24=−5x−20

⟹5x+2y=4.

If we put (4,−6) into this equation, 

LHS=5×4+2×(−6)=8=4=RHS. Which means that the point (4,−6) does not lie on the line joining the points (−4,12) and (0,2). Which is what we wanted to show.

The weighted average cost of capital (WACC) for company C is 6.63%.

The weighted average cost of capital (WACC) is a financial metric that represents the average rate of return a company must earn on its investments to satisfy its shareholders and creditors. It takes into account the proportion of debt and equity in a company's capital structure and the respective costs associated with each.

To calculate WACC, we need to consider the cost of debt and the cost of equity. The cost of debt is the interest rate a company pays on its debt, adjusted for taxes. In this case, the pre-tax cost of debt is 2% and the tax rate is 24%. Therefore, the after-tax cost of debt is calculated as (1 - Tax Rate) multiplied by the pre-tax cost of debt, resulting in 1.52%.

The cost of equity represents the return required by equity investors to compensate for the risk associated with owning the company's stock. Here, the cost of equity for company C is 6%.

The debt represents 10% of the total capital, while the equity represents the remaining 90%. To calculate the weighted average cost of capital (WACC), we multiply the cost of debt by the proportion of debt in the capital structure and add it to the cost of equity multiplied by the proportion of equity.

WACC = (Proportion of Debt * Cost of Debt) + (Proportion of Equity * Cost of Equity)

In this case, the calculation is as follows:

WACC = (0.10 * 1.52%) + (0.90 * 6%) = 0.152% + 5.4% = 6.552%

Therefore, the weighted average cost of capital (WACC) for company C is approximately 6.63%.

Step-by-step explanation:

The absolute value equations in the form x - b = c that have the given solution sets are as follows:

A. |x - 7.5| = 5.5

Explanation: To obtain the solutions x = 2 and x = 13, we set the expression x - b equal to the positive and negative values of c, respectively. Solving the equations x - b = 5.5 and x - b = -5.5 gives us x = 7.5 + 5.5 = 13 and x = 7.5 - 5.5 = 2, respectively.

B. |x - 23| = 0

Explanation: Since x = 23 is the only solution, we set the expression x - b equal to zero, resulting in the equation x - b = 0. Solving this equation gives us x = b = 23.

C. |x - (-1/6)| = 5/6

Explanation: By setting x - b equal to the positive and negative values of c, we obtain the equations x - b = 5/6 and x - b = -5/6. Solving these equations yields x = (-1/6) + (5/6) = 1/2 and x = (-1/6) - (5/6) = -1/3, which are the desired solutions.

D. |x - (-3)| = 0

Explanation: Since x = -3 is the only solution, we set the expression x - b equal to zero, resulting in the equation x - b = 0. Solving this equation gives us x = b = -3.

E. |x - (-4.1)| = 0

Explanation: Since x = -4.1 is the only solution, we set the expression x - b equal to zero, resulting in the equation x - b = 0. Solving this equation gives us x = b = -4.1.

F. x - 5 ≥ 0

Explanation: To represent all numbers greater than or equal to 5, we set the expression x - b greater than or equal to zero. Simplifying the inequality gives us x ≥ 5.

G. -(x - 5) ≥ 0

Explanation: To represent all numbers less than or equal to 5, we set the negation of the expression x - b greater than or equal to zero. Simplifying the inequality gives us -x + 5 ≥ 0.

H. -(x - (-14)) ≥ 0

Explanation: To represent all numbers less than or equal to -14, we set the negation of the expression x - b greater than or equal to zero. Simplifying the inequality gives us -x + 14 ≥ 0.

I. x - (-1.3) ≥ 0

Explanation: To represent all numbers greater than or equal to -1.3, we set the expression x - b greater than or equal to zero. Simplifying the inequality gives us x ≥ -1.3.

The perimeter of the quarter circle with radius 1 yard is approximately 2.57 yards.

To find the perimeter of a quarter circle, we need to add up the lengths of its curved edge and its straight edge.

In this case, the curved edge is a quarter of a circle with radius 1 yard. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Since we only need a quarter of the circumference, we can divide the formula by 4:

C = (2πr)/4

Substituting r = 1, we get:

C = (2π(1))/4

C = π/2

Therefore, the curved edge of the quarter circle has a length of π/2 yards. The straight edge of the quarter circle is simply the radius, which is also 1 yard.

So the perimeter of the quarter circle is the sum of the curved edge and the straight edge:

Perimeter = (π/2) + 1

Using 3.14 for π and adding the two terms, we get:

The total cost function considers the costs of labor and capital, the supply function determines the quantity supplied based on the production function, the profit function calculates the difference between revenue and cost, and the demand function for capital reflects the equilibrium between the marginal product of capital and the rental rate.

a. The total cost function (C) for this firm can be calculated by multiplying the cost of labor (w) with the number of hours of labor (L) and adding it to the cost of capital (r) multiplied by the quantity of capital (K).

So, C = wL + rK.

b. The supply function (MC) for assembled calculators [q(P,v)] can be found by taking the derivative of the production function with respect to q. In this case, MC = ∂q/∂k * ∂k/∂P.

To find q, you will need to substitute the given value of P and v into the production function.

c. The profit function (π) for this firm, stated as a function of the parameters "P" and "v", can be calculated by subtracting the total cost (C) from the revenue (P*q).

So, π = P*q - C.

d. The demand function for capital (k) can be obtained by equating the marginal product of capital (∂q/∂k) to the rental rate (v).

Solve for k to find the demand function for k.

e. The above functions (C, MC, π, k) have the form they do because they are derived from economic principles such as cost minimization, profit maximization, and the marginal productivity of inputs.
