Answer 2

Answer:

The average of the remaining scores is 10.65

Explanation:

(GIVEN)

The average of 11 scores is 10.5

We know the formula of average,

The sum of the quantities ÷ number of quantities = average

sum of 11 scores / 11 = 10.5

sum of 10 scores + 9 = 10.5 x 11

sum of 10 scores = 115.5 - 9

sum of 10 scores = 106.5

Since one score is deleted from the 11 scores so we are left with only 10 scores.

Average of remaining ones = sum of 10 scores  ÷ number of scores

                                             = 106.5  ÷ 10

                                              = 10.65

So the average of the remaining 10 scores is 10.65.
