Answer:
The minimum sample size required is 461.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
An interval estimate of the proportion p with a margin of error of 0.06. What is the minimum sample size required?
The minimum sample size required is n, which is found when M = 0.06.
We don't have an estimate for the true proportion, which means that we use
. So






Rounding up
The minimum sample size required is 461.
The degree of a polynomial is the highest power anything is raised to. so x+3 is the same as x(^1) + 3
<span>so first degree. </span>
<span>x^2 +3 is a second degree</span>
25 sheets at 4000 per sheet.......4000/25 = $ 160 per sheet <==
A = L * W
A = 4 * 8
A = 32 sq ft....multiply by 25 because he bought 25 of them
25 * 32 = 800 sq ft
4000/800 = $ 5 per sq ft <==
Well first move the x's over to get 9X+27=3y and -8x+40=8y. Now just divide to isolate the y . 3x+9= y and -X+5= y.
