Casey said that 40 people were surveyed. Is his answer reasonable?

Answers

If 40 people were surveyed then it is reasonable

It depends on your population size, and if your sample is biased. If your sample was 40 out of 100, then yes, it would be reasonable. But if your sample was 40 out of 1000, then no because the sample is too small.

What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?_____π ft³

Answers

cylinder area=height times area of base (area of base=area of circle)

height =1.8
radius=6.1
area of circle=pi times r^2

area of circle=pi times 6.1^2=37.21π
times height

1.8 times 37.21π=66.978π

volume=66.978π ft^3

A football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards. How many yards do they need to gain on the next play to get back to their original position?

Answers

Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.

The answer would be 4 yards.The expression would be n+8-12 n could be any number so if it was 1 then it would be 1+8-12 which would be -3 you then should know that you would need to add 4 to -3 to make it to the original number which was 1.This works for any other number that you put for n
