Question

if the grades of the exam are averaged at 85% within a margin of error of 7%. then we can solve the equation of |x - 85| = 7 to find the entire range of grades from Minimum to Maximum.Question: in the equation above, 85 represents the what value

When we formulate the equation: | x - 85| = 7, we said that the distance between any grade and the average should be equal to the margin error.

So, 85 represents the average grade of the exam
