A random sample of 48 devices was selected from a warehouse and in turn randomly divided into three groups of 16. Group A was the control group so nothing was done to the devices. Group B devices were submerged in water for 15 minutes. Group C devices were dropped to a cement floor from 5 feet. Each device was then evaluated for performance (the lower the score the better). Does there appear to be any measurable effect of immersing them in water or dropping them

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

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
