The graph is a circle, centered at the origin, with radius=4.
We know that we can write the equation of a circle with radius r and center (a,b) as :
.
Thus, substituting (a, b) with (0, 0) and r with 4, we have:
.
The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:
,
we would still have the same roots.
Thus, the equation of the circle can be written as :
.

We have to find if a student scores 29 on his first test, what will be his equivalent score on the second test. The equivalent scores must have the same z-scores. So we have to find the z-score from 1st test and calculate how much scores in second test would result in that z-score.
The formula for z-score is:
Calculating the z-score for the 29 scores in first test, we get:
This means, the equivalent scores in second test must have the same z-scores.
i.e for second test:
Rounding of to nearest integer, the equivalent scores in the second test would be 86.
The answer of 4/10 - 28/100 is 3/25 in simplest form
