Answer:
The margin of error for a sample size of 250 is 6
Step-by-step explanation:
The margin of error is given as
1/square root of the sample size
Thus, margin of error for a sapless size of 250 is
1/√250
= 1/15. 811
= 6
The two planes intersect in a single line shared by the planes. The line of intersection is NO.
Area of circle = pi * r^2
pi * (3.25)^2 = 33.18307
Rounded = 33.18
Solution: area = 33.28 yd^2
