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.

Bicyclists in a 10-mile race were surveyed about their finishing times in minutes (f) and the number of previous races they had competed in (n). there was a negative linear relationship between f and n that is best modeled by the equation f=−0.45n+43.6 . which statement is true? the model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 43.6 minutes. the model predicts that the average finishing time for a race is 43.6 minutes the model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 0.45 minutes. the model predicts that the finishing time for a bicyclist who has competed in 43.6 previous races is about 0.45 minutes less than his finishing time in his first race.

The matrix below marks with a 1 each pair of the set of racers a, b, c, d, e, f who are to have a drag race together. it is most efficient if a racer can run in two races in a row (but not in three in a row). is it possible to design a sequence of races such that one of the racers in each race (except the last race) also runs in the following race (but not three in a row)? if possible, give the sequences of races (pairs of racers); if not, explain why not.
