What are the mean, median, and mode for the following data set? 15, 34, 78, 90, 100, 75, 87, 71, 75, 78, 82, 90, 94, 78 a. mean- 74.8, median- 78, mode- 78 b. mean- 78, median- 78, mode- 78 c. mean- 73, median- 78, mode- 90 d. mean- 73, median- 78, mode- 75

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

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
