Provide the width of project duration range (not dates) at plus and minus ten percent about the probability of expected completion time based on PERT and MCS results. For example, if the expected completion time is d days, and the corresponding probability is p%, find the duration range corresponding to p-10% to p 10% probability

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
