Answer:
D. Population, because it is a collection of salaries for all teachers in the school.
Step-by-step explanation:
In research, population refers to a complete set of subjects that share a characteristic and that the researcher is interested in. On the other hand, a sample is a subset of a population and it's usually the one the researcher takes to make a study with.
In this example, we have "The salary of each teacher in a school" since we are taking ALL the teachers of this school, this would be a population. If we were working with the salary of only a portion of the teachers of said school, it would be a sample.
Thus, the right answer is D. Population, because it is a collection of salaries for all teachers in the school.
Answer:
See below.
Step-by-step explanation:
Multiplication:
x times 2
x times 2 would be x+x
Basically for each one number, you add the other one by. For example:
3 times 2 : 2+2+2 or 3+3
4 times 7: 4+4+4+4+4+4+4 or 7+7+7+7
Division:
x divided by 2
Division is how many groups of a number can you fit into the first one. For example:
4 divided by 2= Two groups of two can fit into four. (2+2)
6 divided by 3= Two groups of three can fit into six. (3+3)

4m - 7n = 10
2m + 2n = 4 - multiply everything by -1.
4m - 7n = 10
-2m - 2n = -4 Add the 2 equations
(4m - 7n = 10)
+(-2m - 2n = -4)
-------------------------
2m - 9 n = 6.
The value of 2m - 9n would be 6.
