Using the z-distribution, as we are working with a proportion, it is found that 1016 constituents are required.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
The margin of error is given by:
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
The estimate is of 
, while the margin of error is of M = 0.03, hence solving for n we find the minimum sample size.
Rounding up, 1016 constituents are required.

Function:)hope this helped
The best way to write x^2 x x^5 without exponents would be....
x - x - x - x - x - x - x
(by the way this - is multiplication sign idk how to out the dot)
I hope this helps!
Answer:
a = 9/c
Step-by-step explanation:
We want to isolate a. To do this, divide both sides of the given equation by c:
9 ca
---- = -----
c c
This yields
a = 9/c
65-20 = 45
45/.75 = 60 miles
I hope this isn't to vague
