TecArt 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?

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 Inean and standard deviation.

.95

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

i think this is a open ended question but i agree with other guy who said you should ask it at english section

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
