To determine the cost for a given mileage we just need to plug the later in the equation; in this case we know that m=16, then we have:

Therefore, it cost $34.20 to travel sixteen miles.

Answer:

A

Step-by-step explanation:

You can easily eliminate option C. since the figure will not be rotated in the same position by just translating.  You can also eliminate D. because a rotation of the figure will not be just 3 units away from the new figure; therefore not proving its congruence.  Lastly, you can eliminate option B. because two simple reflections will not land the figure in the same place, it has to be translated as well.  With all of this you can conclude that the answer must be A.  

I really hope this helps you!  :)

To calculate the principal repaid by the 17th monthly payment of $750 on a $22,000 loan at 15% compounded monthly, we need to calculate the monthly interest rate, the remaining balance after 16 payments, and the interest portion of the 17th payment.

The monthly interest rate is calculated by dividing the annual interest rate by the number of compounding periods per year. In this case, it would be 15% / 12 = 1.25%.

The remaining balance after 16 payments can be calculated using the loan balance formula:

\($$B = P(1 + r)^n - (PMT/r)[(1 + r)^n - 1]$$\)

Where B is the remaining balance, P is the initial principal, r is the monthly interest rate, n is the number of payments made, and PMT is the monthly payment amount.

Substituting the values into the formula, we get:

\($$B = 22000(1 + 0.0125)^{16} - (750/0.0125)[(1 + 0.0125)^{16} - 1]$$\)

After calculating this expression, we find that the remaining balance after 16 payments is approximately $17,135.73.

The interest portion of the 17th payment can be calculated by multiplying the remaining balance by the monthly interest rate: $17,135.73 * 0.0125 = $214.20.

Therefore, the principal repaid by the 17th payment is $750 - $214.20 = $535.80.

Cindy should hire the 12th worker as it would result in a net increase in profit, with additional revenue exceeding the cost of hiring. Insufficient information is provided to determine the demand curve for labor or compare its elasticity. Events that would shift the factory's demand for capital include new, more efficient machines and rising wages due to a labor shortage.

a. To determine whether Cindy should hire a 12th worker, we need to compare the additional revenue generated with the additional cost incurred. Hiring the 12th worker would increase total revenue by $150 ($2,750 - $2,600) per day, but it would also increase costs by $100. Therefore, the net increase in total profit would be $50 ($150 - $100). Since the net increase in profit is positive, Cindy should hire the 12th worker.

b. By hiring the 12th worker, Cindy can increase her total revenue from $2,600 per day to $2,750 per day. The additional revenue generated by the 12th worker exceeds the cost of hiring that worker, resulting in a net increase in profit.

c. To determine the firm's demand curve for labor, we need information about the marginal product of labor (MPL) and the wage rates. Unfortunately, this information is not provided, so we cannot complete the labor demand table or derive the demand curve for labor.

Without specific data or information about changes in the quantity of labor demanded and wage rates, we cannot determine which demand curve (from part b or c) is more elastic. The elasticity of the demand curve depends on the responsiveness of the quantity of labor demanded to changes in the wage rate.

The events that would shift the factory's demand for capital are:

a. New shoemaking machines being twice as efficient as older machines would increase the productivity of capital. This would lead to an increase in the demand for capital as the factory would require more capital to produce the same quantity of shoes.

b. The wages that the factory has to pay its workers rising due to an economy-wide labor shortage would increase the cost of labor relative to capital. This would make capital relatively more attractive and lead to an increase in the demand for capital as the factory may substitute capital for labor to maintain production efficiency.

The event "Many consumers decide to walk barefoot all the time" would not directly impact the demand for capital as it is related to changes in consumer behavior rather than the production process of the shoemaking factory.

The 95% confidence interval estimate for the standard deviation of the wake times is (30.64, 65.09) minutes.

In order to construct the confidence interval estimate, we use the formula:

CI = (s/√n) * t

Where s is the sample standard deviation, n is the sample size, and t is the critical value from the t-distribution with (n-1) degrees of freedom for a desired confidence level.

Given that the sample mean wake time is 98.9 minutes and the sample standard deviation is 41.6 minutes, and with a sample size of 15, we can calculate the confidence interval.

Using the t-distribution table for a 95% confidence level and (n-1) degrees of freedom (14), we find the critical value to be 2.145.

Substituting the values into the formula, we get:

CI = (41.6/√15) * 2.145 ≈ (30.64, 65.09) minutes

This means that we are 95% confident that the true standard deviation of wake times for the population lies within the interval of (30.64, 65.09) minutes.

The change in equilibrium real GDP is B220.

To calculate the change in equilibrium real GDP resulting from an increase in autonomous investment, we need to use the expenditure-output model. In this model, equilibrium real GDP (Y) is determined by the aggregate expenditure (AE), which is the sum of consumption (C), investment (I), government spending (G), and net exports (NX). The equation is:

Y = AE = C + I + G + NX

Given the information provided, let's calculate the initial equilibrium real GDP (Y) using the given values:

C = 80 + (9/10)Y

DI = 1800

G = 1600

TR = 10

T = (1/3)Y

Substituting the values into the equation:

Y = (80 + (9/10)Y) + 1800 + 1600 + 10 - (1/3)Y

Simplifying the equation:

Y = 3490 + (5/6)Y

Multiplying through by 6 to remove the fraction:

6Y = 6(3490) + 5Y

6Y = 20940 + 5Y

Y = 20940

The initial equilibrium real GDP is 20940.

Now, let's calculate the equilibrium real GDP after the B220 increase in autonomous investment (ΔI):

Y' = Y + ΔI

Substituting the values:

Y' = 20940 + B220

Calculating the change in equilibrium real GDP:

Change in Y = Y' - Y

Change in Y = (20940 + B220) - 20940

Change in Y = B220

The change in equilibrium real GDP is B220.

To find the angle of least nonnegative measure that is coterminal with θ = -570°, we can add or subtract multiples of 360° until we get an angle between 0° and 360°.

We can start by adding 360° to -570°:

-570° + 360° = -210°

This is still negative, so we can add another 360°:

-210° + 360° = 150°

This is between 0° and 360°, so the angle of least nonnegative measure that is coterminal with θ = -570° is 150°. Therefore, 0c is 150°.

The correct answer is:

p = 0.539, q = 0.461.

To find the point estimates for p and q, we use the given information that out of 1023 US adults surveyed, 552 claimed to have worked the night shift at one time.

The point estimate for p, the proportion of US adults who have worked the night shift, is calculated by dividing the number of individuals who claimed to have worked the night shift by the total number of adults surveyed:

p = 552/1023 = 0.5395 (rounded to four decimal places)

The point estimate for q, the proportion of US adults who have not worked the night shift, is calculated by subtracting the point estimate for p from 1:

q = 1 - p = 1 - 0.5395 = 0.4605 (rounded to four decimal places)

Therefore, the point estimates for p and q are:

p = 0.5395

q = 0.4605

If the distance to a star was suddenly cut in half, it would appear four times brighter.

The brightness of a star is directly proportional to the inverse square of its distance from us. This means that if the distance to a star is halved, its brightness will increase by a factor of four.

The relationship between brightness and distance can be expressed as follows:

B = k / d^2

where B is the brightness, k is a constant of proportionality, and d is the distance.

If the distance to the star is halved, it can be expressed as:

d' = d / 2

Plugging this into the equation for brightness, we get:

B' = k / (d / 2)^2

Expanding this and simplifying, we get:

B' = 4 * k / d^2

Since k is a constant, it cancels out and we are left with:

B' = 4 * B

This means that if the distance to a star was suddenly cut in half, it would appear four times brighter. In astronomical terms, this is equivalent to an increase of 2 magnitudes on the logarithmic magnitude scale.

i) Wealth is not independent of income.

ii) It is unclear whether there is multicollinearity in the model due to the lack of correlation or VIF values.

iii) The a priori sign of X3i is negative, indicating an expected negative relationship between wealth and consumption expenditure. However, without additional information, we cannot determine if the results conform to the expectation.

Let us discuss in a detailed way:

i) To test whether wealth (X3i) is independent of income (X2i), we can examine the coefficient associated with X3i in the regression equation. In this case, the coefficient is -0.0424. To test for independence, we can check if this coefficient is significantly different from zero. Since the coefficient has a value of -0.0424, we can conclude that wealth is not independent of income.

ii) Multicollinearity refers to a high correlation between independent variables in a regression model. To determine if there is multicollinearity, we need to examine the correlation between the independent variables. In this case, we have income (X2i) and wealth (X3i) as independent variables. If there is a high correlation between these two variables, it suggests multicollinearity. We can also check the variance inflation factor (VIF) to quantify the extent of multicollinearity. However, the given information does not provide the correlation or VIF values, so we cannot definitively conclude whether there is multicollinearity in the model.

iii) The a priori sign of X3i can be determined based on the expected relationship between wealth and consumption expenditure. Since the coefficient associated with X3i is -0.0424, we can infer that there is an expected negative relationship between wealth and consumption expenditure.

In other words, as wealth increases, consumption expenditure is expected to decrease. However, without knowing the context or specific expectations, we cannot determine if the results conform to the expectation.

Since the training set consists of 40 observations, you would need to fill in the counts for each category based on the actual classifications made by the model using the 0.5 cutoff value.

To construct the confusion matrix for a 40-observation training set, we need to use a cutoff value of 0.5 to classify each profile observation as either interested or not interested. The confusion matrix is a tool that shows the performance of a classification model.

Let's denote the four possible outcomes as follows:
- True Positive (TP): The model correctly classified an observation as interested.
- True Negative (TN): The model correctly classified an observation as not interested.
- False Positive (FP): The model incorrectly classified an observation as interested when it was actually not interested.
- False Negative (FN): The model incorrectly classified an observation as not interested when it was actually interested.

Since we have a cutoff value of 0.5, any observation with a prediction score above or equal to 0.5 will be classified as interested, while any observation with a prediction score below 0.5 will be classified as not interested.

Based on this information, we can construct the confusion matrix:

Answer/Step-by-step explanation:

If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.

Total income estimated in a month:

Sales: $950 per week = 950*4weeks = $3,800 per month

Services: $2,875 per month

Total estimated income per month = $(3,800 + 2,875) = $6,675

Total expenses estimated in a month:

Rent: $4,500 per month

Travel: $7.5 per day = 7.5*7days = $52.5 per week.

Assuming there are 4 weeks in a month, expenses for travel in a month will be:

$52.5*4 = $210

Merchandise: $1,650 per month

Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360

Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

If the interest were compounding weekly instead of semi-annually, the account would have been worth more. To calculate how much more, we can use the formula:

A = P(1 + r/n)^(nt)
The difference in the final amount is: $17,135.03 - $16,270.90 = $864.13


Hi! To answer your question, let's first calculate the future value of the account for both semi-annual and weekly compounding interest.

1. For semi-annual compounding (interest compounded every 6 months):
Initial deposit: $6,500
Interest rate: 3.3% per year (0.033 per year or 0.0165 per 6 months)
Number of compounding periods: 30 years * 2 = 60

Future Value = Initial deposit * (1 + Interest rate per period)^(Number of periods)
Future Value = $6,500 * (1 + 0.0165)^60 ≈ $16,883.62

2. For weekly compounding (interest compounded every week):
Initial deposit: $6,500
Interest rate: 3.3% per year (0.033 per year or 0.00063462 per week)
Number of compounding periods: 30 years * 52 weeks = 1560

Future Value = Initial deposit * (1 + Interest rate per period)^(Number of periods)
Future Value = $6,500 * (1 + 0.00063462)^1560 ≈ $17,110.79

Now, let's find out how much more the account would be worth if the interest were compounded weekly instead of semi-annually:

Difference = Future Value (weekly compounding) - Future Value (semi-annual compounding)
Difference = $17,110.79 - $16,883.62 ≈ $227.17

If the interest were compounding weekly, the account would be worth approximately $227.17 more.

The midpoint formula and the normal vector of the plane can be used to determine the equation of the plane that contains all points equidistant from the points (1,0,-2) and (3,4,0).

Given by: The midpoint of the two points is:

M = [(1 + 3)/2, (0 + 4)/2, (-2 + 0)/2] = (2, 2, -1) (2, 2, -1)

The following vector runs between the two points:

V = (3 - 1, 4 - 0, 0 - (-2)) = (2, 4, 2) (2, 4, 2)

The cross product of two non-parallel plane vectors yields the normal vector to the plane. The midpoint M to a point on the plane is one such vector, while the other is the vector V. Consider the point P = (2, 2, -1) + t(2, 4, 2) as an illustration, where t is a scalar.

The normal vector is then provided by:

N = V x (P - M) = (2, 4, 2) x (2t, 4t, 2t -1), which equals (12t, -8t, 4t + 2)

The point-normal form, which makes use of the normal vector N and the point M, can be used to determine the equation for the plane:

(x - 2) * 12t = (y - 2) * -8t = (z + 1) * 4t + 2

The final equation of the plane is obtained by multiplying both sides of the equation by t and setting t 0.
