The median of a continuous random variable hav- ing distribution function f is that value m such that f (m) = 1 . that is, a random variable is just as 2 likely to be larger than its median as it is to be smaller. find the median of x if x is (a) uniformly distributed over (a, b); (b) normal with parameters μ, σ 2 ; (c) exponential with rate λ.

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
