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.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
