<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:
x=9
Step-by-step explanation:
-4|x-3| = -16
-4+x-3 = -16
-7+x = -16 (add -4 and -3)
x = -16+7 (add -7 to -16)
x=9

ninety-nine
technically this does not start with nine
Answer:
Step-by-step explanation:
so the steps to doing this are as follows :
Subtract the accepted value from the experimental value.
Take the absolute value of step 1.
Divide that answer by the accepted value.
Multiply that answer by 100 and add the % symbol to express the answer as a percentage.
|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%
