Answer:
Randal will charge $4099.75.
Step-by-step explanation:
Randal builds and sells cabinets.
He charges $18 per hour of labor. While pricing, he considers the cost of materials and the time he will spend on the project. Then he adds 15% for operational costs.
Andrea’s cabinets will require $2,125 of materials and 80 hours of labor.
So, total charges will be : dollars
Now 15% operational costs on $3565 is :
dollars
So, the total cost Randal will charge = dollars.
Therefore, Randal will charge $4099.75.

Given :
- ∠F = ∠J
- ∠D = ∠H
- ∠E = ∠I
Sum of all angles in a triangle = 180°
Which means :
- 41 + 20 + 15x - 1 = 180
- Thus, the value of x = 18
Measure of angle 15x-1 :
Thus, the measure of angle 15x-1 = 119°
Let us place 8 in the place of x to see if we have found out the correct measure of the angles :
Since the measures of all the angle sum up to form 180°, we can conclude that we have found out the correct measure of each of the angles.
Therefore, the value of x = 8
<h2><u>My answer</u> :</h2>Answer:
The alternative hypothesis is .
The critical value is
Step-by-step explanation:
It is claimed that proportion in favor of proportion A is greater than 60%.
This means that at the null hypothesis, we test if the proportion is of at most 60%, that is:
At the alternative hypothesis, we test if the proportion is more than 60%, that is:
What is (are) the critical value?
The critical value is the value of Z with a p-value 1 subtracted by the standard significance level of 0.05, since we are testing if the mean is more than a value, so, looking at the z-table,
