Question

here are the fuel efficiencies (in mpg) of 8 new cars. 42, 16, 54, 13, 31, 23, 13, 27 what is the percentage of these cars with a fuel efficiency less than 32 mpg?

Explanation:

Step1: Count number of cars with fuel - efficiency less than 32 mpg

There are 6 cars (42, 16, 13, 31, 23, 13, 27) with fuel - efficiency less than 32 mpg out of 8 cars.

Step2: Calculate the percentage

The formula for percentage is $\frac{\text{Number of favorable cases}}{\text{Total number of cases}}\times100\%$. So, $\frac{6}{8}\times100\% = 75\%$.

Answer:

75%
