Answer:
a) n = 1037.
b) n = 1026.
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 
.
(a) Assume that nothing is known about the percentage to be estimated.
We need to find n when M = 0.04.
We dont know the percentage to be estimated, so we use 
, which is when we are going to need the largest sample size.
Rounding up
n = 1037.
(b) Assume prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less.
So
Rounding up
n = 1026.
The answer is C
1/2(5x + 12)
because the perimeter is equal 20x + 6
Answer: 
Step-by-step explanation:
Given: The rent of waterslide per day = $500
Let x be the a charge per hour of use.
The number of hours bounce house was used = 5 hours
Since, the total charge was $800.
Therefore, the equation can be used to find the charge x, in dollars, per hour of use is given by :-
Fixed charge+5 times x=Total charge
