Mary is deciding whether to book the cheaper flight home from college after her final​ exams, but​ she's unsure when her last exam will be. She thinks there is only a ​%10 chance that the exam will be scheduled after the last day she can get a seat on the cheaper flight. If it is and she has to cancel the​ flight, she will lose ​$150. If she can take the cheaper​ flight, she will save ​$50. ​a) If she books the cheaper​ flight, what can she expect to​ gain, on​ average? ​b) What is the standard​ deviation?

Answers

Answer 1

Answer:

(a) Expected gain = 30

(b) Standard deviation = 66.03

Explanation:

From the question, we are given the following:

Probability of loss = 10%

Loss amount = $150

Probability of Saving = 100% - Probability of loss = 100% - 10% = 90%

Saving amount = $50

Therefore, we proceed as follows:

a) If she books the cheaper​ flight, what can she expect to​ gain, on​ average?

This can be calculated as follows:

Expected gain = (Probability of loss * (-Loss amount)) + (Probability of Saving * Saving amount) = (10% * (-150)) + (90% * 50) = -15 + 45 = 30

b) What is the standard​ deviation?

Standard deviation can be described as a measure of the amount of variation a set of values. This can be calculated from the variance as follows:

Variance = (Probability of loss * (-Loss amount - Expected gain)^2) + (Probability of Saving * (Saving amount - Expected gain)^2) = (10% * (-150 - 50)^2) + (90% * (50 - 30)^2) = (10% * (-200)^2) + (90% * (20)^2) = (10% * 40,000) + (90% * 400) = 4,000 + 360 = 4,360

Standard deviation = Variance^0.5 = 4,360^0.5 = 66.03

A country that allows the value of its currency to be set by global supply and
demand for that currency has a(n) exchange rate.
A. fixed
B. inflated
c. trade-weighted
D. flexible

Answers

Answer:

D. flexible

Explanation:

An exchange rate set by the market forces is a flexible exchange rate or a floating exchange rate. The demand and supply forces of the currency determine the exchange rate in the Forex market. Since governments are a major stakeholder in a country's exchange rate, it makes some efforts to influence the exchange rate.

If the demand for a currency is high, its value increases, meaning other countries will spend more buying it. When demand is low, its value declines, which makes imports expensive.

Teresa is considering purchasing a home for $220,000 by taking out a loan with an interest rate of 4.3% for 30 years. What would her monthly payment be?

Use the monthly payment formula to calculate the monthly payment for this loan:

M =
M = monthly payment

P = principal

r = interest rate

t = number of years

Answers

Answer:

$1,088.144

Explanation:

The applicable formula is as below as derived form annuity concepts.

M  = PV   ×      r        

                       1 − (1+r)−n

where p= $220,000

r = 4.3% interest rate per year;

             Per month interest  rate = 0.043 /12=0.00358

r = 30 year, in months = 30 x 12 =360

 

Therefore

M= $220,000  x    0.00358

         1-(1+0.00358) ^ - 360

M=$220,000 x   0.00358

                            1 - 0.2762

M = $220,000 x(0.00358 /0.7238

M = $220,000 x 0.00494611

M = $1,088.144

A person’s credit score can range from a low of 300 to a high of what number?

Answers

Answer:

Explanation:

A person's credit score can range from a low of 300 to a high of 850 numbers.

A credit score is a number from 300 to 850 that rates a consumer’s creditworthiness. The higher the score, the better a borrower looks to potential lenders.

A credit score is based on credit history: number of open accounts, total levels of debt, repayment history, and other factors. Lenders use credit scores to evaluate the probability that an individual will repay loans in a timely manner. There are several different credit bureaus in the United States, but only three that are of major national significance: Equifax, Experian, and TransUnion. This trio dominates the market for collecting, analyzing, and disbursing information about consumers in the credit markets.

Units sold 1,200 Price $ 10 Sales $ 12,000 Variable manufacturing costs 4,800 Fixed manufacturing costs 2,400 Variable selling costs 1,200 Fixed administrative costs 1,200 Required: Using the data provided, compute the margin of safety and margin of safety ratio.

Answers

Answer:

Margin of safety is 480 units

Margin of safety ratio is 40%

Explanation:

The Margin of Safety is the difference between sales and Breakeven sales in terms of Dollar or Volume.

First, we need to calculate the following values

Fixed cost = Fixed manufacturing costs + Fixed administrative costs =  $2,400 + 12,00 = $3,600

Variable cost = ( Variable manufacturing costs + Variable selling costs ) / Units sold = ( $4,800 + $1,200 ) / 1,200 units = $5

Contribution per unit = Selling price - Variable cost =  ) = $10 - $5 = $5

Breakeven sales = Fixed cost / Constribution = $3,600 / $5 = 720 units

To calculate the Margin of Safety, use the following formula

Margin of Safety = Sale - Breakeven sale = 1,200 units - 720 units = 480 units

Margin of safety ratio = Margin of safety / Sales = 480 units / 1,200 units = 0.40 = 40%
