1. Three drivers competed in the same fifteen drag races. The mean and standard deviation for the race times of each of the drivers are given.

Driver A had a mean race time of 4.01 seconds and a standard deviation of 0.05
seconds.

Driver B had a mean race time of 3.96 seconds and a standard deviation of 0.12
seconds.

Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19
seconds.

a. Which driver had the fastest typical race time?
driver b

b. Which driver's race times were the most variable?

c. Which driver do you predict will win the next drag race? Support your prediction
using the mean and standard deviation,

i saw this question before, dont know the asnwer srry

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.

step-by-step explanation:

i think the answer is 90 hope this
