The way that the gallup can adjust their sample size is; to multiply it by 4
<h3>What is sample size?</h3>
The formula for margin of error is;
E = zs/√n
where;
s is standard deviation
n is sample size
Thus;
Since we want to cut margin of error in half from 3 percentage points to 1.5 percentage points, since the standard deviation and z-score will remain the same, the way to do it will be to increase the sample size by multiplying it by 4.

1=1^3
8=2^3
27=3^3
64=4^3
125=5^3
These are all perfect cubes. 1^3 is the same as 1*1*1. The question is asking you to find which number, when multiplied by itself 3 times results in the given number.
Answer:
102
Step-by-step explanation:
5(1/2)-2(2/3)=11/2-8/3=(11*3)/(2*3)-(8*2)/(3*2)=(3*11-2*8)/6=(33-16)/6=17/6=2(5/6)
so the answer is 17/6 or 2(5/6)
The answer is C, if I'm wrong text me sometime and please explain it for me
