WebThe PERT Mathematics. BETA probability distribution is what works behind PERT. The expected completion time (E) is calculated as below: E = (TOPT + 4 x TLIEKLY + TPESS) / 6. At the same time, the possible variance (V) of the estimate is calculated as below: V = (TPESS - TOPT)^2 / 6^2. WebThe only variable I don't have a value for is the growth constant k, which also happens to be what I'm looking for. So I'll plug all the known values into the exponential-growth formula, and then solve for the growth constant: A = Pekt. 450 = 100 e6k. 4.5 = e6k. ln (4.5) = 6 k. ln (4.5) / 6 = k = 0.250679566129...
