The mean of 6 scores is 12.5 of the scoresare 13 ,10 ,14, 12, 10 . a)What is the 6th score?
b) after the 7th score, the mean is 13 , what is the 7th score?

a. 16

b. 16

Step-by-step explanation:

a. First multiply 12.5 by six because the mean is all the numbers added together and divided by the # of scores. 12.5x6= 75

Then add together 13, 10, 14, 12, and 10 which is = 59

Subtract those and its 16.

b. Is the same steps except you replace 12.5 by 13 and 6 by 7.

answer: do you still need this?

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
