Answer:
And rounded up we have that n=8068
Step-by-step explanation:
The margin of error for the proportion interval is given by this:
(a)
We want for this case a 95% of confidence desired, our significance level would be given by 
and 
. And the critical value would be given by:
The margin of error for this case is 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is 
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=8068
Answer:
A
Step-by-step explanation:
First I converted the fractions into decimals to make it easier to solve.
2 1/2 —> 2.5
1 3/4 —> 1.75
Then I added the two decimals together.
2.5 + 1.75 = 4.25
Then I divided this number by 100 (the number of cups in one bag)
100/4.25=23.529
With this equation I know that one bag lasts 23 full days.
This is almost a month, and so it would not make sense for the answers to be B, C, or D.
Hope this helped

Answer:
To express your answer in terms of pi, simply refrain from substituting pi's numerical value for its symbol in the equation. That way, your answer will look like xπ where x is whatever number you come up with, and π is simply a placeholder.
