Find the Mean Absolute Deviation of the Following data set: Test Scores: 90, 85, 85, 75, 70, 70,50,50
I

71.9

Step-by-step explanation:

the answer will be 71.875

Step-by-step explanation:

if you add all of the numbers 90+ 85+ 85+ 75+ 70+ 70+50+50

it gives u 575 and then you divide by the total of the numbers that it would be 8 so 575/8 = 71.875

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

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
