Mr. venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test. write an inequality that represents the test scores of 60% of his students?

Step-by-step explanation:

Let x represent the test scores of 60% of his students.

We have been given that Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test.

We will use tolerance formula to solve our given problem.

Using rule , then , we will get:

Therefore, the inequality represents the test scores of 60% of Mr. Venn's students.

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
