There are four activities on the critical path, and they have standard deviations of 1, 2, 4, and 2. what is the probability that the project will be completed in 38 weeks if its expected completion time is 40 weeks?

abde or 1,2,4, 5 is the answer

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
