<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

The answer is c. 10%
We know that the antique dealer would normally charge 20% more than the price he purchased the item for. This also means that the antique dealer is making a profit of 20% on the items he sells. If the antique dealer hosts a 10% off sale, he is reducing the profit he is making from 20% to 10%.
The answer is A because 9 x 9 x 9 = 729. The exponent above the 9 means to multiply the base (9) 3 times.
Question 1:
Sub the coordinates in for x and y
Y=-6x + b
1=-6(-4) +b
1= 24 +b
-23=b
Final answer: Y=-6x -23
Repeat for question 2
Question 3:
Slope = y2-y1/x2-x1
8-11/2- -4
-3/6= -0.5
Slope is -0.5
Sub x and y into equation
Y=-0.5x +b
11=-0.5(-4) +b
11=2+b
9=b
Y=-0.5x +9
Repeat for question 4
5.5(20 + 18.5)
5.5(38.50)
211.75
