Known fact:
- $100 dollars for 8 hours of work --> $100 / 8hrs = $12.50 dollars/hrs
Two hours of work = $12.50 dollars/hr * 2hrs = $25 dollars
Six hours of work = $12.50 dollars/hr * 6hrs = $75
Ten hours of work = $12.50 dollars/hr * 10hrs = $125
fourteen hours of work = $12.50 dollars/hr * 14hrs = $175
Thus the answer is the bottom left choice.
Your calculation for the cylinder volume is 31,792.50 cubic feet
I calculate it as 31,808.63 cubic feet
So, the 10,000 cubic feet mark would be located at
(10,000 / 31,808.63) * 45 feet =

from the top
and that rounds to 31 feet
I get the same answer as you.
Answer:
Option B) Margin of error becomes smaller
Step-by-step explanation:
We are given the following information in the question:
A poll to determine the percentage of adults who gamble at least once a month.
We have to find what happens to the confidence interval as the sample size increases.
Margin of error =
Confidence interval:
As the sample size increases, the margin of error decreases.
As the margin of error decreases the width of the confidence interval decreases.
Option B) Margin of error becomes smaller
