So to find the medium you need to put the numbers in order from least to greatest so for the first one it would be like this 103, 111, 113, 114, 122, 129,
<span>130, 138, 140, 141, 145 and then you find the number that is in the middle of the set so for sample one it would be 129</span>

<h3>Answer: $14,137.30</h3>

Work Shown:

A = P*(1+r)^t

A = 21450*(1+(-0.08))^5

A = 21450*(1-0.08)^5

A = 21450*(0.92)^5

A = 21450*0.6590815232

A = 14137.29867264

A = 14,137.30

Notice how I used a negative r value to indicate depreciation rather than growth.

I need help give me help is it A B C D
Wewaii [24]

Answer:

A

Step-by-step explanation:

To get the area of the badgers in yards, you would have to do 40 yds * 20 yds / 2. Your answer should be 400 yds. Then, you would change it into feet. For every one yard, it is three feet. Therefore you would multiply the 400 yds by 3 to get it into feet. Now that you have it into feet, you can multiply it by the number of 1.25 per square feet.

400 ft * 1.25 =1500.
