The area of the carpet must be <u>greater than 20 square yards</u> for which Rugs Emporium charges more than Carpets 4U.
<u><em>Explanation</em></u>
Suppose, the number of square yards of carpet is 
Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for
square yards of carpet 
Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for
square yards of carpet 
If the Rugs Emporium charges more than Carpets 4U , then the inequality will be.....

So, the area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.
Answer:
2
Step-by-step explanation:
Given f(x) = x + 1 and g(x) = -2x + 5, find f(g(2)).
First, we must plug in the value of g(x) into f(x).
f(g(x)) = (-2x+5) + 1
Then, we plug in g(x)'s x-value.
f(g(2)) = (-2(2) + 5) + 1
Now, we solve.
f(g(2)) = (-4 + 5) + 1
f(g(2)) = 1 + 1
f(g(2)) = 2

<h3>What is the margin of error?</h3>
Your results will deviate from the actual population value by how many percentage points, as indicated by the margin of error.
We have the following info:
ME = 50 margins of error desired
= 1000 the standard deviation for this case
The margin of error is given by this formula:
(a) 
And on this case, we have that ME =50 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b) 
The critical value for the 99% of confidence interval now can be founded using the normal distribution. The significance is
= 0.01. And for this case would be
= 2.58, replacing into formula (b) we got:

So the answer for this case would be n=2663 rounded up to the nearest integer.
