Consider the following work breakdown structure:
time estimates (days)
activity precedes optimistic most likely pessimistic
start a, b, c - - -
a d 38 50 62
b e 90 99 108
c end 85 100 115
d f 19 25 31
e end 91 100 115
f end 62 65 68
what is the estimated expected (mean) time for project completion?

The estimated expected (mean) time for project completion is 440 hours.

Explanation:

The given breakdown structure is

Activity         Precedes         Optimistic       Most Likely         Pessimistic  

A                         D                      38                      50                      62  

B                         E                      90                      99                      108  

C                         End                  85                      100                    115  

D                         F                       19                       25                      31  

E                         End                   91                      100                     115  

F                         End                   62                      65                      68

Using the table we get

The formula for estimated expected (mean) time for project completion is

Therefore the estimated expected (mean) time for project completion is 440 hours.

if kj of heat is transferred o 1200 g liquid water at 36'c, what would the new temperature of the water be? (he specific heat capacity of liquid water is 4.186 j/g''c)

a. 15'c

b.100'c

c.51'c

d.36'c
