Answer:
1. The population of interest is all city goverments in the U.S.
5. The parameter of interest is the proportion of the city goverments in the U.S. that provide electricity to their residents.
Step-by-step explanation:
Hello!
Missing questions:
Which of the following is true? Select all that apply.
- The population of interest is all city governments in the U.S.
- The population of interest is the 192 cities.
- The population of interest is all city governments that provide utilities to their residents.
- The population of interest is 6.25%
- The parameter of interest is the proportion of the city governments in the U.S. that provide electricity to their residents.
- The parameter of interest is 6.25%
- The population of interest is the 20 counties.
- The parameter of interest is the list of all counties in the U.S.
The objective of this essay is to test utilities provided by city governments, for this a sample of 20 counties was taken then contacted each city of them counting how many of them provided utilities to their residents, finding out that 12 out of 192 cities (6.25%) provided electricity to their residents.
The study variable is:
X: Number of city governments that provide utilities (electricity) to their residents, in a sample of 192.
The population of the study is the city governments in the U.S.
And the parameter of interest is the population proportion of city governments in the U.S. that provide electricity to their residents.
I hope it helps!

Step-by-step explanation:
1,091 + 176 = 1,267
Answer:
option 1 and 4
Step-by-step explanation:
The elimination method should be used when there are two variables with the same number in front of them but different signs.
In the first system, the first equation has -8y while the second one has 8y.
Both equations have an 8y with different signs therefore using the elimination method would be most logical.
In the fourth system, the first equation has a -4x while the second one has 4x.
Both equations have 4x with different signs therefore using the elimination method would be most logical
Reasons it can't be the other options :
In the second system, no variable has the same number before it so no variable can be eliminated unless you multiply the equations by a common multiple. The best method for this system would be graphing
In the third system y is defined by an expression therefore using the substitution method is the most logical approach.
Yes it is the answer to x+5 36=2
