A survey of 100 high school students provided this frequency table on how students get to school:
What is the probability that a randomly selected student
Is a junior?

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

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

78.59 is the mean
