Need an answer for this

Answer 1

Explanation:

a) Colin's mean score:

Add up the 10 given run scores and then divide the sum by 10:

(18 + 12 + 6 + 1 + 21 + 10 + 21 + 18 + 20 + 7) / 10, or

134 / 10. Thus, Colin's mean score was 13.4.

b) After Colin has played his 11th game, his average becomes:

134 + 9

----------- = 143/11 = 13

11
