Answer:
The missing volume of gas is 6 liters
Step-by-step 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
[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}[/tex]
[tex]7 = \frac{4+5+13+x}{4}[/tex]
[tex]7 \times 4=4+5+13+x[/tex]
28=22+x
28-22=x
6=x
Hence The missing volume of gas is 6 liters
