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.

The equation of the circle x² + y² – 18x + 8y + 5 = 0 can be written as in the standard form is (x – 9)² + (y + 4)² = 92
<h3>What is a circle?</h3>
It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given below.
x² + y² – 18x + 8y + 5 = 0
Add and subtract 97, then we have
x² – 18x + y² + 8y + 97 – 97 + 5 = 0
x² – 18x + 81 + y² + 8y + 16 – 92 = 0
(x – 9)² + (y + 4)² = 92
