Answer and explanation:

In order to avoid sample bias, it is important to make a classification of the teenagers being studied by categorizing them according to race, family composition, and drugs used, for instance. This will allow the researcher to compare similar samples of the two different facilities instead of picking some randomly without taking into consideration factors like the mentioned above.

A famous quarterback just signed a contract for $16 mil, providing $3.6 million a year for 4 years. A less famous receiver signe
Damm [24]

Answer:

The PV of the famous quarterback is $11,662,991.56, while the PV of less famous receiver is $12,719,159.63.

Explanation:

Present value (PV) refers to the valuation date value of a stream of income expected to be received in the future.

The PV for each of the two contracts can calculated by using the interest rate of 9%% (i.e. 0.12) as the discounting factor (r) to calculate the PV for each year. The discounting formula to use is (1+r)^n where n represents each relevant year. The calculations are done as follows:

1. For a famous quarterback

Step 1. Calculation of the PV for year

Year 1 PV = $3,600,000 ÷ (1.09)^1 = $3,302,752.29  

Year 2 PV = $3,600,000 ÷ (1.09)^2 =  $3,030,047.98  

Year 3 PV = $3,600,000 ÷ (1.09)^3 = $2,779,860.53

Year 4 PV = $3,600,000 ÷ (1.09)^4 = $2,550,330.76  

Step 2. Calculation of the total PV

This is obtained by adding the PVs of year 1 - 4 calculated above, and this is equal to $11,662,991.56.

2. For a less famous receiver

Step 1. Calculation of the PV for year

Year 1 PV = $3,000,000 ÷ (1.09)^1 = $2,752,293.58  

Year 2 PV = $3,000,000 ÷ (1.09)^2 =  $2,525,039.98  

Year 3 PV = $3,000,000 ÷ (1.09)^3 = $2,316,550.44  

Year 4 PV = $3,000,000 ÷ (1.09)^4 = $2,125,275.63  

Step 2. Calculation of the total PV

This is obtained by adding the PVs of year 1 - 4 calculated above, and this is equal to $9,719,159.63.

In addition, the $3,000,000 is to receive now is added to the $9,719,159.63 as follows:

PV of less famous receiver = $9,719,159.63 + $3,000,000

                                             = $12,719,159.63

Conclusion

Therefore, the PV of the famous quarterback is $11,662,991.56, while the PV of less famous receiver is $12,719,159.63.

Suppose we have a bond issue currently outstanding that has 20 years left to maturity. The coupon rate is 8% And coupons are pai
cluponka [151]

Answer:

c. 10%

Explanation:

The Yield to Maturity(YTM) of the Bond is the cost of the debt. So, we need to find the YTM first.

Here i will use a Financial Calculator to enter and compute the YTM as follows :

N = 20× 2 = 40

PMT = ($1,000 × 8%) ÷ 2 = $40

PV = $828

P/YR = 2

FV = 1,000

I or YTM = ?

Thus the cost of the Bond is 10%

Chandler Tire Co. is trying to decide which one of two projects it should accept. Both projects have the same start-up costs. Pr
mojhsa [17]

Answer:

The second project should be chosen. Because the present value of the second project is greater than that of the first project.

Explanation:

The project that should be chosen can be determined by comparing the present value of both projects.

Present value is the cash flows from a project discounted at the discount rate.

Present value can be found using a financial calculator;

For project 1,

Cash flow each year from year one to six is  $52,000

Discount rate = 15%

Present value =$196,793.10

For project 2,

Cash flow each year from year one to eight is  $48,000

Discount rate = 15%

Present value =$215,391.43

The second project would be chosen because its present value is greater than that of the first project.

I hope my answer helps you
