Complete Question:

Femi's last 5 bowling scores were 68, 75, 72, 90, and 80.  What was Femi's mean score?

Answer:

Step-by-step explanation:

Given

Scores: 68, 75, 72, 90, and 80

Required

Determine the mean

The mean (M) of a data is calculated as thus:

$M = \frac{\sum x}{n}$

Where

n = number of data.

In this case,

n = 5

and

$\sum x$ = sum of data

So, the formula becomes

$M = \frac{68 + 75 + 72 + 90 + 80}{5}$

$M = \frac{385}{5}$

$M = 77$

Hence, the mean is 77
