Answer:

B. NON-REPRESENTATIVE

Step-by-step explanation:

<em>The sample does not represent the population as a researcher is taking a sample from the hospital where the cholesterol level of the patient is generally high and the researcher is not randomly selecting the U.S. citizens.</em>

Thus, option (B) is correct.

Further, the sample is a subset of the population and it is easy to analyze as compared to the population.

The sample is said to be representative if it represents the whole population.

What are the next two numbers in the pattern 3,6,5,10,9,18,17.
LenKa [72]
This pattern appears to alternate between doubling and subtracting by 1. 

To get from 3 to 6, we multiply by two.
To get from 6 to 5, we subtract one.
To get from 5 to 10, we multiply by two.
To get from 10 to 9, we subtract one.
To get from 9 to 18, we multiply by two.
To get from 18 to 17, we subtract one.

Therefore, next we need to multiply by two.
17 x 2 = 34
So, the next number is 34.

To find the number after, we subtract one.
34 - 1 = 33
Thus, the number after is 33.

In conclusion, the next two numbers are 34 and 33.

Which equations represent the line shown in the graph?
zaharov [31]
The given graph is a straight line passing through points (-4, -3) and (1, 5)
Equation in point slope form is y + 3 = (5 - (-3))/(1 - (-4)) (x - (-4))
y + 3 = 8/5(x + 4)
y + 3 = 8/5x + 32/5
y = 8/5x + 32/5 - 3
y = 8/5x + 17/5

Multiplying through by 5 gives
5y = 8x + 17
-8x + 5y = 17
Options B and C are the correct answers.
