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:

Step-by-step explanation:
Since the sample size is quite large, we can use the z-distribution.
The margin of error is given by

Where n is the sample size, s is the sample standard deviation and
is the z-score corresponding to a 90% confidence level.
The z-score corresponding to a 90% confidence level is
Significance level = α = 1 - 0.90= 0.10/2 = 0.05
From the z-table at α = 0.05
z-score = 1.645

Therefore, the margin of error is 0.776.
Answer:
k = 8
Step-by-step explanation:
7(k - 5) = 21
k - 5 = 3
k = 8
