Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.
To find the mean you have to add all the numbers up and divide them by the total amount of numbers you have
To find the median you have to order the numbers form least to greatest then cross numbers out
0.92 , 0.479 , 0.387 , 0.2
[See the last first digit after the decimal. I chose 0.92 since 9 is the greater than 2,3 and 4]
Convert 23 lbs to ounces (23 lbs is 368 ounces)
add 3 (371)
You would multiply the weekly amount by the number of weeks (w) and add that to the one time fee:
t = 90w + 80
