The variance for this activity is mathematically given as
Var=0.026
<h3>What is the variance for this activity?</h3>
A data set's variance may be seen as a measurement of the spread that exists between the individual integers. When evaluating the asset allocation of a portfolio, investors employ an expression known as the variance equation.
After careful consideration of the table given in the question, we have that
Pessimistic time tp=2
optimistic time to=1
most likely time tm=1.5
Generally, the equation for variance is mathematically given as

Therefore

Var=0.026
In conclusion, the variance for this activity
Var=0.026

Answer:
Vanessa's height is 63.
Step-by-step explanation:
I got 63 because I thought 2 + ? = 5 so I thought of 3 and then I thought what is 1 + ? = 7 and I got 6, so if I put the two answers together it is 63.
Hope it helps

Answer:
0.681
Step-by-step explanation:
Let's define the following events:
S: a Carter office worker is rated satisfactory
U : a Carter office worker is rated unsatisfactory
ND: a Carter office worker is placed by Nancy Dwyer
DN: a Carter office worker is placed by Darla Newberg
We have from the original text that
P(S | ND) = 0.8, this implies that P(U | ND) = 0.2.
P(S | DN) = 0.65, this implies that P(U | DN) = 0.35. Besides
P(DN) = 0.55 and P(ND) = 0.45, then we are looking for
P(DN | U), using the Bayes' formula we have
P(DN | U) =
=
=0.681
