What is the median of this set of data?

71,37,22,81,65,54,52,41,48,71

The median is 53.

Step-by-step explanation: First, you put the numbers in order from smallest to largest (22, 37, 41, 48, 52, 54, 65, 71, 71, 81). Next, you cross off one number from each end until you reach the middle two, or one in some cases. In this case, the middle two numbers were 52 and 54. To find the median of these to numbers, you must find the middle. The number between 52 and 54 is 53, so the median of this data set is 53.

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
