How would you find an interquartile range with just numbers? For exe, 0,2,4,0,2,3,8,6. After you unscramble them, you do you know what the iqr is?

IQR is 3.5

Step-by-step explanation:

Step 1: Organize the numbers in numerical order

0,0,2,2,3,4,6,8

Step 2: Break the set up into quartiles (4 parts)

0 0 | 2 2 | 3 4 | 6 8

Step 3: Find the average of each quartile

0 | 2 | 3.5 | 7

Step 4: Find the IQR (Q3-Q1)

3.5-0=3.5

Therefore, the IQR is 3.5

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
