An internet service provider charges $18 per month plus an initial set up fee. one customer paid a total of $81 after 2 months o

frosja888 [35]

Ok so
cost=setupfee+costused
costused=(number of months) times (cost per month)
if we represent number of months as x
we know cost per month is 18
18x is costused
and in 2 m onts, he paid 81 so
81=startup fee +18x
2 monts so x=2
81=startupfeee+36
subtract 36
45=startup fee

5 monts is x=5
45+18(5)=45+90=135

A. cost=18x+45
B. $45
C. $135

Anit [1.1K]

Standard deviations of the four activities of the critical path are 1,2,4,2.

Standard deviation of this critical path = Sum of square root of variance of this corresponding critical path

Standard deviation of critical path $=\sqrt{1^2+2^2+4^2+2^2}$
