Incomplete question. However, I answered from a general research perspective.
<u>Explanation:</u>
Note, the term <u>sample </u>used in statistical research refers to subjects or persons carefully selected (using a particular sampling method/type ) to represent the target population.
A randomly selected sample could be done as either:
- Simple Random Sampling
- Stratified Random Sampling
- Cluster Random Sampling.
- Systematic Random Sampling.
<u>Using any of the above sampling methods could result in 70% of the population being from low-income families as this is a matter of chance. Hence, we can agree with the research results.</u>

Answer:
Step-by-step explanation:
Using the same proportion as the previous question
11/x = x / 8 Cross multiply
x^2 = 88 Factor 88 into at least 1 perfect square and something
x^2 = 4 * 22 Take the square root of both sides
x = sqrt(4 * 22)
x = 2*sqrt(22)
Answer:
-11/2
Step-by-step explanation:
To solve this, use slope intercept formula
y2 - y1
---------------
x2-x1
1-12
---------
1-(-2)
-11
--------
2
-11/2
