There are black and blue marbles in a jar. Two are drawn without replacement The probability of the fire marble is blue is 0.31 The probability that the first marvel is blue in the second marble is black is 0.12 what is the probability to the nearest hundred of the second marble being black if the first marvel was blue

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
