Step-by-step explanation:
-The minimum sample size to get a desired margin of error, E is calculated using the formula:
-Given that 
, we can substitute to solve for n in the above formula:
Hence, the desired minimum sample size, n is 42 adult men.
Answer:
The problem is stated as:
Min C = 15*(2*x +y) + 21*y
subject to x*y = 450
Step-by-step explanation:
Given that the region is rectangular, it has two opposite sides called x and two other opposite sides called y (both measured in feet). Then, the area (in square feet) is:
A = x*y = 450
One of the sides called y costs $21 per linear foot. The other 3 sides (two x and one y) costs $15 per linear foot. Then, the cost function is:
C = 15*(2*x +y) + 21*y
D=2r so the diameter is 10.4ft. Multiple 10.4ft by 3.14 to get the answer. The answer is 32.656
