Someone please help me out! :-)

a sample; It is much easier to collect sample data in this situation.

Step-by-step explanation:

It would be very difficult out how many students have a summer job in an entire state. There's just too many people to ask. For this reason, a sample would be needed, meaning it's one of the two bottom choices.

The reasoning for the very last choice is faulty as samples can still provide biased data.

So, it must be the third choice.

what is all that apply?

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
