average score on all 7 tests?​

Answer 1

Given :-

• Average score on the first 4 tests was 97 points.
• Average score on the next 3 tests was 91 points.

To Find :-

• What was Mike's average score on all 7 tests ?

Solution :-

we know that,

• Average = sum of observations / Total number of observations .

so,

→ Average score on the first 4 tests was = 97 points.

then,

→ Total points he scored = 97 * 4 = 388 points .

similarly,

→ Average score on the next 3 tests was = 91 points.

then,

→ Total points he scored = 91 * 3 = 273 points .

therefore,

→ Total points in 7 test = 388 + 273 = 661 .

hence,

→ Average = (Total Points) / (Total test) = 661/7 = 94.42 points (Ans.)
