Answer 2

Calculating the Average and Determining the Required Grade

To find the average grade for the student in mathematics, we can sum up all the grades and then divide by the total number of grades.

The given grades are: 3, 4, 3, 3, 2, 5, 4, 2, 2, 4, 5.

Let's calculate the average:

Sum of grades = 3 + 4 + 3 + 3 + 2 + 5 + 4 + 2 + 2 + 4 + 5 = 37 Total number of grades = 11

Average grade = Sum of grades / Total number of grades = 37 / 11 = 3.3636 (rounded to 4 decimal places)

Now, let's determine what grade the student needs to achieve in order to raise the average to a desired level.

The student's current average grade is approximately 3.3636. If the student wants to achieve a higher average, they will need to aim for a higher grade in the next assessment.
