Question

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.

a. |x + 2.2| = 78
b. |x − 2.2| = 78
c. |x + 78| = 2.2
d. |x − 78| = 2.2

Answers

  1. The equation that represents the minimum and maximum scores is |x − 78| = 2.2

    What is an equation?

    An equation is an expression that shows the relationship between two or more numbers and variables.
    Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
    Let x represents a student’s score. Since the average score on a lab report is 78 points, Hence:
    |x − 78| = 2.2
    The equation that represents the minimum and maximum scores is |x − 78| = 2.2
