Answer:
-9 < r < -7
Step-by-step explanation:
9 + 3r < 2 + 2r
r < -7
-3 - 5r < 6 - 4r
-9 < r
r > -9
-9 < r < -7
This looks unusual but let's try it.
x+4=x+8
Let's move the x vales to the left and numbers to the right.
x-x=8-4
0=-4
Hm. This doesn't work, does it?
This equation has no solution. If you believe you typed it wrong, correct it in the comment seciton.
Answer: 2,500
5/7 of 3500 = (5/7)*(3500)
5/7 of 3500 = (5/7)*(3500/1)
5/7 of 3500 = (5*3500)/(7*1)
5/7 of 3500 = (17500)/(7)
5/7 of 3500 = 2500
Hope this helped:)
Answer:
For this case the population is described as:
All the college students
And the political have a list of 3456 undergraduates at her college for the sampling frame.
The sample would be the 104 students who return the survey.
Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.

For this case we can also find the non reponse rate since we know that the total of questionnaires are 250 and she got back just 104 answered
So we have a non response rate of 58.4 %
Answer:
non proportional
