In science class, the average score on a lab report is 78 points, with all students scoring within 2.2 points of the average. If x represents a student's score, write an equation that represents the minimum and maximum scores.

|x + 2.2| = 78
|x − 2.2| = 78
|x + 78| = 2.2
|x − 78| = 2.2

Respuesta :

Based on the average score in the lab report and the scoring range, an equation that would represent the minimum and maximum scores is |x − 78| = 2.2.

What equation shows the minimum and maximum scores?

Assuming a student gets the maximum score, then it means that they are 2.2 points above the average.

If the average was subtracted from their score therefore, the result would be 2.2:

x - 78 = 2.2

This is the same if their score was the minimum. When the average is subtracted from their score, the result would be -2.2.

The best way to show this is therefore:

|x − 78| = 2.2
