An equation that represents the minimum and maximum scores is; |x - 82| = 3.2.
<h3>How to write an absolute value equation?</h3>
The absolute value function is defined by:
f(x) = x, x ≥ 0.
f(x) = x, x < 0.
It measures the distance of a point x to the origin.
For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:
|x - 82| = 3.2.
