Answer: B

Step-by-step explanation:

For the left side of the graph, the dot is not shaded so it is not equal, thus a and d are wrong.

c is wrong as well as the left side of the graph is x less than 1 and not more than so from the process of elimination, we get that the answer is B

Adrian knows that the quotient of 0.75 divided by 0.8 is less than 1. He knows that the quotient of 0.8 divided by 0.75 is great

MrRa [10]

Hey There!

Adrian knows this because whenever you divide something less than the number you are dividing, in this case, then the quotient will be less than one. If you divide something that is greater than the number you are dividing, than in this case, the answer will be greater than one.

You have just used the network planning model and found the critical path length is 30 days and the variance of the critical pat

joja [24]

Answer:

0.726 is the probability that the project will be completed in 33 days or less.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 30 days

Variance = 25 days

Standard Deviation,

$\sigma = \sqrt{\text{Variance}} = \sqrt{25} = 5$

We assume that the distribution of path length is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(completed in 33 days or less)

$P( x \leq 33) = P( z \leq \displaystyle\frac{33 - 30}{5}) = P(z \leq 0.6)$

Calculation the value from standard normal z table, we have,

$P(x \leq 33) = 0.726 = 72.6\%$

0.726 is the probability that the project will be completed in 33 days or less.
