Here are the fuel efficiencies (in mpg) of 10 new cars. 28, 25, 30, 22, 16, 41, 35, 18, 52, 35
What is the percentage of these cars with a fuel efficiency less than 19 mpg?

20%

Step-by-step explanation:

Cars that are less than 19  mpg : 16, 18

2 cars have less than 19 mpg.

2/10  cars have less than 19 mpg.

To change fraction to percentage :

divide the numerator by the denominator, then multiply the decimal by 100

2/10 = 0.2

0.2*100 = 20

20%

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
