Sarah has a bag of jolly ranchers. there are 15 grape, 20 blue raspberry, 10 watermelon, 8 cherry, and 7 green apple jolly ranchers in a bag. a) what is the probability that she will choose a grape jolly rancher? b) what is the probability that she will choose either watermelon or cherry? c) what is the probability that she will not choose green apple? explain your reasoning.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
