<span>The independent variable is the size of the aquarium and the dependent variable is the size of the fish population. All other variables in this scenario are held constant. Dependent variables are aspects that the researcher deliberately changes to see what will result from the change. If the food, water temperature and cleanliness are the same and the size of the aquariums is different, that makes aquarium size the independent variable.</span>

If inflation is increasing at 2.4 percent per year, and your salary increases at the same rate, how long will it take your salar
Oksana_A [137]

Answer:

it take 29.23 years, my salary to double.

Explanation:

To make the salary double I have to increase the value of salary by 100%. If inflation rate is 2.4 percent per year and salary increase the same rate the time period to make it double can be calculated as follow.

As every year 2.4% has compounding effect, so we will use compounding formula to solve this problem.

Target value = Existing value ( 1 + growth rate )^time period

200% = 100% ( 1 + 2.4% )^n

2 = 1 ( 1 + 0.024 )^n

2 = 1 ( 1.024 )^n

2 = 1.024^n

Taking log on both sides to solve the n

Log 2 = n Log 1.024

n = Log 2 / Log 1.024

n = 29.23 years

I will take 29.23 year to double the salary

A Treasury bill with a par value of $100,000 due three months from now is selling today for $97,087 with an effective annual yie
Zanzabum

The effective annual yield of a treasury bill is equivalent to 12.55%.

Option B is the correct answer.

<h3>What is the treasury bill?</h3>

The treasury bill is the trading instrument that is issued in the money market by the government.

Given values:

Par value: $100,000

Future value: $97,087

Number of years from now: 3 years

Step-1 Computation of interest rate of treasury bill:

\rm\ Interest \rm\ rate \rm\ on\rm\ treasury \rm\ bill=\frac{\rm\ Par \rm\ value - \rm\ Future \rm\ value}{\rm\ Future \rm\ value} \\\rm\ Interest \rm\ rate \rm\ on\rm\ treasury \rm\ bill=\frac{\$100,000-\$97,087}{\$97,087} \\\rm\ Interest \rm\ rate \rm\ on\rm\ treasury \rm\ bill=0.03

Step-2 Computation of equivalent yield the bill:

\rm\ Equivalent \rm\ annual \rm\ yield =(\rm\ 1+ \rm\ interest \rm\ rate)^{\rm\ Number \rm\ of \rm\ years}  - 1\\\rm\ Equivalent \rm\ annual \rm\ yield=(1+0.03)^{4} -1\\\rm\ Equivalent \rm\ annual \rm\ yield=1.01255-1\\\rm\ Equivalent \rm\ annual \rm\ yield=0.01255

Therefore, 12.55% is the equivalent yield on the treasury bill.
