If a parachutist lands at a random point on a line between markers A and B, find the probability that she is closer to A than to B. 0.5 Correct: Your answer is correct. Find the probability that her distance to A is more than seven times her distance to B.

i believe it's a.

i'm not sure on this one, most likely correct.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
