the answer is 8

Explanation:

i took the test

Answer 2

B. 6.5 days

Explanation:

The estimated time for completing an activity can be computed if we have optimistic time, most likely time and pessimistic time

The formula is:

`T_e = (T_0+4T_m+T_p)/(6) \\where\\T_0 = Optimistic\ Time\\T_m = Most\ likely\ time\\T_p=Pessimistic\ time`

For activity B:

`T_0=3\\T_m=6\\T_p=12`

Putting the values in the formula

`T_e = (3+4(6)+12)/(6)\\T_e=(3+24+12)/(6)\\T_e=(39)/(6)\\T_e=6.5\ days`

The correct answer is:

B. 6.5 days ..
