Answer:
15
Step-by-step explanation:
PERT estimate is a measuring strategy that is based on a weighted average. It is used in measuring the uncertainty and risk via three estimates to determine an estimated likelihood for a project's cost or period of completion.
The formula is (O + 4M + P) ÷ 6
Where P is the most pessimistic = 29
M is the most likely = 12
O is the most optimistic = 10
Hence we have (10 + [4*12]+ 29) ÷ 6
= (10 + 48 + 29) ÷ 6
= 87÷6 = 14.5 ≈ 15
Rounded figure is equal to 15.
Hence the final answer to the question is 15
A)
Earlier, The length of the angelfish =
inches
Now, the length of angelfish =
inches
We have to determine the grown length of angelfish
=
- 
= 
LCM of '2' and '3' is '6',
= 
=
inch
Therefore, the angelfish has grown by
inch.
B)
We have to determine the increased length of angelfish in feet.
Since
foot
So, 
= 0.069 foot.
The awnser is (-1+3/x-3/x2+1/x3 )
