a class of 25 students took a spelling test. two students scored 100 on each test, nine students scored 95 on each test, ten students scored 90 on each test, three students scored 80 on each test and one student scored 70. what is the average score of the spelling test rounded to one decimal place? enter your answer in the box.

Answer

Explanation:

Step1: Calculate total score

[2\times100 + 9\times95+10\times90 + 3\times80+1\times70] [= 200+855 + 900+240 + 70] [=2265]

Step2: Calculate average score

The average score is the total score divided by the number of students. So, (\frac{2265}{25}=90.6)

Answer:

90.6
