Given:
μ = 9.9 hours, population mean
σ = 4.54 hours, population standard deviation

For the random variable x = 3 hours, the z-score is
z = (3 - 9.92)/4.54 = -1.5242

From standard tables, obtain
P(x ≤ 3) = 0.064 = 6.4%


Answer: 6.4% on both tails of the normal distribution

F 1What is the yield to maturity on a 10-year, 9% annual coupon, $1,000 par value bond that sells for $887.00? That sells for $1
Llana [10]

Answer:

When the bond is sale at premium, it means the market rate is lower than coupon rate. So investor purchase the bond a higher price until the bond yield equal the market rate

If sold at discount, the market rate is higher than coupon rate. This means it's sold below face value to increase the bond yield to market rate.

YTM if market price is 887 =  10.7366190%

YTM if market price is 1,134.2= 7.1764596%

Explanation:

For the YTM we can calculate an estimated using the following formula:

YTM = \frac{C + \frac{F-P}{n }}{\frac{F+P}{2}}

Where:

C= coupon payment 1,000 x 9% = 90

F= face value of the bonds = 1000

P= market price = 887

n= years to maturity = 10

YTM =  10.7366190%

YTM = \frac{C + \frac{F-P}{n }}{\frac{F+P}{2}}

C= 90

F= 1000

P= 1134.2

n= 10

YTM = 7.1764596%

A more precise answer can be achieve using excle or a financial calculator.

Suppose the U.S. Drug Enforcement Agency steps up its efforts to control the illegal importation of cocaine into the United Stat
nikklg [1K]

Answer:

The Price of Cocaine would rise drastically

Explanation:

If U.S Drugs Enforcement Agency impose higher restrictions in an effort to control illegal import of cocaine into the United States, this would directly impact the market for illegal drugs in the following ways:

  • Since more restrictions get imposed, the procurement cost of cocaine alongside the risk associated with it in the form of higher penalties and prosecution, both will rise.
  • The supply of cocaine would shrink in the market.
  • The above two outcomes would result into the procurers and peddlers demanding much greater price for the same quantity of cocaine so as to compensate for the higher risk assumed and higher procurement costs associated.

Thus, price of cocaine will rise drastically as an outcome of such a move.

Fynjy0 [20]

Answer:

The correct answer is $7,056.46

Explanation:

Giving the following information:

You want to save sufficient funds to generate an annual cash flow of $55,000 a year for 25 years as retirement income. How much do you need to save each year if you can earn 7.5 percent on your savings?

Final value= 55,000*25= 1,375,000

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (1,375,000*0.075)/[(1.075^38)-1]= $7,056.46
