Question

the mean of 5 scores is 7.2
what is the sum of the scores

Answer 1

Answer:

36

Step-by-step explanation:

Step 1 of 2:

Mean is nothing but the average of all numbers.

The formula to find mean or average is,

$Mean =\frac{sum of all numbers}{Total count of numbers}$

Step 2 of 2:

Given that; mean = 7.2 & Total count = 5

Let the sum of scores be $x$.

Substitute in the mean formula and solve for$x$.

$7.2 =\frac{x}{5}$

$x=7.2\times5\\x=36$

Therefore, the sum of 5 scores is 36.
