Given:
The inequality is
To find:
The solution set for the given inequality.
Solution:
We have,
Divide both sides by 3.
It can be written as
Subtracting 4 from each side, we get
The solution set of the given inequality is (-5,-3).
Therefore, the correct option is A.
Answer: answer is 8 because -5 + 1 = -4 then + 10 = 4
Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.

The sample of any set would be smaller version of a larger group. It is often a subset that contains some or all the characteristics of the main set, or the larger general population. The usage of samples comes into play in statistics when the population sizes of interest are too large for the test to contain all the needed members for it to take place. So, from this question, the sample size is the 325 questionnaires that were returned in the first place.
2. C
I thin the answer is survey with little bias since the voters know what they want. This is because while answering the survey, the voters know who they want to vote for upfront, and didn't need to gave their mind change by anyone on the survey.
