The mean of nine test scores is 61%. if a score of 71 is added to the group of scores, what is the new mean?

62%

Step-by-step explanation:

The answer is 62% because:

the nine test scores are 61%

To find the total amount of points she/he got, we multiply. 61x9=549

To find the tenth, we add.

549+71= 620

Then, we divide by 10 to find the TOTAL mean.

We get 62.
