Question

The mean score on a set of 17 tests is 70. Suppose two more students take the test and score 68 and 61. What is the new​ mean?

Answer 1

the mean is basically the average of the numbers

we can calculate that by using this formula

`m = (sum \: of \: terms)/(number \: of \: terms)`

first add both terms

`61 + 68 = 129`

then divide the value 129 by number of terms

we know that the number of terms is two so

`(129)/(2)`

so when we divide the answer is equal to

`64.5`

hope that helps !
