Question

In a college statistics course, one's grade is the average of three exams. Meghan scored 91 on the first and 84 on the second. What grade does she need on the final exam to have an A (90%) for the course overall?

Answer 1

To have an overall grade of 90% in the course, Meghan needs to score a 95 on the final exam.

Step-by-step explanation:

To calculate the grade Meghan needs on the final exam, we can use the formula for finding the average: (91 + 84 + x) / 3 = 90. Solving for x, we get x = 95. Therefore, Meghan needs to score a 95 on the final exam to have an overall grade of 90% for the course.
