Answer 2

The missing volume of gas is 6 liters

Explanation:

The following data points represent the volume of gas in each race car driver's tank (in liters):

4,5, 13, ?

Let the missing value be x

Data : 4,5,13,x

`Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}`

`7 = (4+5+13+x)/(4)`

`7 * 4=4+5+13+x`

28=22+x

28-22=x

6=x

Hence The missing volume of gas is 6 liters
