The travel time for a college student traveling between her home and her college is uniformly distributed between 40 and 90 minutes.61. Refer to Exhibit 6-2. What is the random variable in this experiment?a. the uniform distributionb. 40 minutesc. 90 minutesd. the travel time

d. the travel time

Step-by-step explanation:

We are studying the travel time for the college student, which is between 40 and 90 minutes, distributed uniformly.

40 and 90 minutes are the intervals of the variable, and the variable is the travel time, which is random. Uniform is how the distribution is characterized, which means that each outcome(travel time beween 40 and 90 minutes) is equally as likely.

So the correct answer is:

d. the travel time

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

5 x 14?

im new, sorry if this is wrong.
