Question

The average of eight scores is 14.5. Two more scores recorded are 17 and 18. What is the average of the ten scores?

Answer 1

Therefore, the average of the ten scores is 15.1.

Explanation:

To find the average of the ten scores, we need to sum all of the scores and divide by the number of scores. The sum of the eight scores is 8 * 14.5 = 116. The sum of the two additional scores is 17 + 18 = 35. The total sum of all ten scores is 116 + 35 = 151. The average of the ten scores is therefore 151 / 10 = 15.1.
