High School

In a class of 8 students, the test scores are 10, 20, 15, 25, 30, 15, 25, and 36 out of 50 in Geography. What is the average score?

A) 20
B) 21
C) 22
D) 25

Answer :

The average score is 22, so the correct answer is C) 22.

To find the average score, we use the formula:

[tex]\text{Average} = \frac{\text{Sum of all scores}}{\text{Number of students}}[/tex]

First, we sum the scores:

10 + 20 + 15 + 25 + 30 + 15 + 25 + 36 = 176

Then, we divide by the number of students (8):

[tex]\frac{176}{8} = 22[/tex]

Thus, the average score is C) 22.

Answer:

C. 22

Step-by-step explanation:

10 + 20 + 15 + 25 + 30 + 15 + 25 + 36 = 176

176 ÷ 8 = 22
