Answer:

a) The number of people that are being studied.

Step-by-step explanation:

1) The (missing) options are:

a) The number of people that are being studied.

b) red blood cell count

c) height

d) none of the above

2) Explanatory variables are synonymical terms for independent variables.

In short when those variables are really not affected by other ones they are also called Explanatory Variables.

It is useful to make a distinction between response variable, and explanatory ones. The first one is affected somehow and it is the response Doris wants to find out.

3) Certainly, the sample or population of this research is absolutely free of prior influence over the final results. Since theoretically, the same research can be done over different samples and find other responses.

Then it's "a"

What is the approximate area of a sector given O= 56 degrees with a diameter of 12m?

jeyben [28]

Area of sector is 17.584 meters

Solution:

Given that we have to find the approximate area of a sector given O= 56 degrees with a diameter of 12m

Diameter = 12 m

Radius = Diameter / 2 = 6 m

An angle of 56 degrees is the fraction $\frac{56}{360}$ of the whole rotation

A sector of a circle with a sector angle of 56 degrees is therefore also the fraction $\frac{56}{360}$ of the circle

The area of the sector will therefore also be $\frac{56}{360}$ of the area

$\text{ sector area } = \frac{56}{360} \times \pi r^2\\\\\text{ sector area } = \frac{56}{360} \times 3.14 \times 6^2\\\\\text{ sector area } = 17.584$

Thus area of sector is 17.584 meters
