Answer:
4 balloons for each balloon animal.
Step-by-step explanation:
Amira sells balloon animals. The given table compares the number of balloon animals sold and the remaining number of balloons on a certain day.
Animals Balloons
15 200
24 164
33 128
When she sold 15 animals the leftover balloons were 200.
then she sold 24 animals the number of leftover balloons were 164.
The difference of the number of items = 24 - 15 = 9 more animals sold
The difference of the leftover balloons = 200 - 164 = 36 balloons used
Now the number of her sold animals was = 33
and the left over balloons = 128
The number of sale was increased by 24 to 33 = 33 - 24 = 9 more animals
and the leftover balloons now 164 to 128 = 164 - 128 = 36 used
Therefore, we can see each sale of 9 balloon animals she used 36 balloons.
so Amira used for each balloon animal =
= 4 balloons.
Amira used 4 balloons for each balloon animal.
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

Now we need to find the probability that the project will completed in 38 weeks given that its expected completion time is 40 weeks.
That is, we need to find P(X<38) :
Probability
Thus the probability that the project will be completed in 38 weeks is 0.34.
