GRADES On her first four quizzes, Rachael has earned scores of 21, 24, 23, and 17 points. What score must Rachael
Shkiper50 [21]
Answer:
20

Explanation:
For the mean to be 21, the total of the 5 numbers must be 21*5= 105

To find what the final quiz score must be, we need to subtract the first 4 scores from 105. 105- 21- 24- 23- 17= 20

We can check this answer by finding the median of the 5 numbers now (17,20,21,24,23). The new median is 21 which means the final quiz score must be 20!

Hope this helped! :)
