Jim's scores on his first four college exams were 72,98,86,and 88.What is his mean score?

OpenStudy (anonymous):

I believe to get the mean you add up all the numbers and divide by the number of numbers you have.

Take the sum of all the four exams score and divide it by 4..

OpenStudy (anonymous):

\[Average \; Or \; Mean = \frac{Sum \; of \; all \; observation}{Number \; of \; Observations}\]

OpenStudy (anonymous):

344 divided by 4

OpenStudy (anonymous):
