Let the number be x, then we have:-
3√x = 12x
squaring both sides:-
9x = 144x^2
144x^2 - 9x = 0
9x( 16x - 1) = 0
16x - 1 = 0 so x = 1/16 answer

Step-by-step explanation:
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.
