Answer: 0.75

Explanation:

Mean(μ) = 300

Standard deviation(σ) = 20

Find the z-score of a person who scored 315 on the exam ;

Raw score (x) = 315

Z = (raw score - mean) ÷ standard deviation

Z = (x - μ) ÷ σ

Z = (315 - 300) ÷ 20

Z = 15 ÷ 20

Z = 0.75

andreyandreev [35.5K]

Answer:

retained earnings 175,500

      common stock               48,750

      paid in excess of par   126,750

Explanation:

The diivdends are 15% so we multiply this by the shares outstanding to know the amount of shares:

65,000 x 15% = 9,750 shares

Then we multiply by the market value to know the amount needed:

9,750 x $18 market value = $175,500 stock dividends

The common stock will be 9,750 at par

and the remainder will be paid in excess.

9,750 x 5 = 48,750 CS

175,500 - 48,750 = 126,750

How much would you have to deposit today if you wanted to have $54,000 in five years? Annual interest rate is 8%. (PV of $1. FV
mestny [16]

Answer:

Instructions are listed below.

Explanation:

Giving the following information:

A) How much would you have to deposit today if you wanted to have $54,000 in five years? The annual interest rate is 8%.

We need to use the following formula:

PV= FV/(1+i)^n

PV= 54,000/(1.08^5)= $36,751.49

B) Assume that you are saving up for a trip around the world when you graduate in two years. If you can earn 7% on your investments, how much would you have to deposit today to have $14,500 when you graduate?

PV= 14,500/1.07^2= $12,664.86

C) Calculate the future value of an investment of $643 for eleven years earning an interest of 8%.

FV= PV*(1+i)^n

FV= 643*1.08^11= $1,499.24

D) Would you rather have $643 now or $1,000 eleven years from now?

It depends on the interest rate. We will assume 8%.

PV= 1000/1.08^11= 428.88

It is better to have $643 today.
