Using the table, give the percentage associated with each unit of standard deviation in the standard normal curve to the nearest hundredth.

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

the answer is:

mean: 6

mad: 2.14

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
