Answer:
6, 1, 8, -16
Step-by-step explanation:
For each input we divide it by 2 and then add 3 to get the output:
6/2+3=3+3=6
-4/2+3=-2+3=1
For each output we subtract 3 and multiply it by two to get the input:
(7-3)*2=4*2=8
(-5-3)*2=-8*2=-16
Answer:
The method for selecting a stratified sample is to order a population in some way and then select members of the population at regular intervals. - FALSE.
This can be re written as :The method for selecting a systematic sample is to order a population in some way and then select members of the population at regular intervals.
Explanation for stratified sampling:
In stratified sampling, the members of a population are divided into two or more strata with similar characteristics and then a random sample is selected from each strata. This way ensures that members of each group within a population will be sampled.
Explanation for cluster sampling:
The method for selecting a cluster sample is to order a population in some way and then select members of the population at regular intervals.
In cluster sampling, the population is divided into clusters, and all of the members of one or more clusters are selected.

Answer:
The x-intercept is at (2,0).
Step-by-step explanation:
The x-intercept(s) can be found by setting y to 0 and solving for x.
Your equation is:
4x+2y=8.
To find x-intercept replace y with 0:
4x+2(0)=8
4x =8
Divide both sides by 4:
x =2
The x-intercept is at (2,0).
