Answer:
181 1/4 square feet
Step-by-step explanation:
The square feet of carpet is needed to cover the floor would b equal to the area of the floor
area of a rectangle = length x breadth

Answer with Step-by-step explanation:
Since we have given that
Average per week in sales = $8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increase the average sales per salesperson
So, the appropriate null and alternate hypothesis would be

b. What is the Type I error in this situation? What are the consequences of making this error?
Type 1 error are those errors in which null hypothesis are supposed to be rejected, but it does not get rejected.
It means sales per week is greater than $8000 but in actual it is not.
c. What is the Type II error in this situation? What are the consequences of making this error?
Type 2 are error are those errors in which null hypothesis are supposed to be accepted but it get rejected.
It means average sales per week is actually $8000 but it is calculated that average sales is less than $8000.
Answer:
Step-by-step explanation:
-2(p + 4) = 3 - 3p + 1p.....combine like terms
-2(p + 4) = 3 - 2p...distribute the -2 through the parenthesis
-2p - 8 = 3 - 2p
-2p + 2p = 3 + 8
0 = 11 <==== no solution
if it is a false statement, it has no solutions
if it ends like : 6 = 6 or -2 = -2, then there is infinite solutions
if it ends like : x = 8 or x = -5, then there is 1 solution
