Mauricio, a project manager at a reputed firm, has been assigned to handle a new project that the firm has received. This project involves a lot of scheduling that has to be handled by Mauricio. Mauricio estimates that the first module of the project could be completed in as few as 15 days or could take as many as 25 days, but most likely will require 20 days. Determine the expected task duration.

20 days

Step-by-step explanation:

Expected Task duration

= (O + 4 M + P)/6

Where O = best case scenario = 15 days

P = worst case scenario = 25 days

M = Usual scenario = 20 days

Therefore, expected task duration

= [15 + 4 (20) + 25] ÷ 6

= 120 ÷ 6

= 20 days.

Therefore expected task duration is 20 days.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
