Answer: 6.95
=====================================
Explanation:
The reference angle is angle S = 41 degrees. The side opposite that (RT) is unknown and what we want to find. The adjacent side to the reference angle is TS which is 8 units long.
RT = x
TS = 8
The ratio of the opposite and adjacent side is equal to the tangent of the reference angle, so,
tan(angle) = opposite/adjacent
tan(41) = x/8
--------------
We are given the value of tan(41) to be approximately 0.869, which means we will replace "tan(41)" with this decimal value and then isolate x by multiplying both sides by 8. This happens in the section below.
--------------
tan(41) = x/8
0.869 = x/8
8*0.869 = 8*x/8
6.952 = x
x = 6.952
x = 6.95
RT = 6.95

In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling and random group assignment
Explanation:
The terms Random sampling and Random group assignment are greatly different in process of the sample selection. The study related to the determination of how sample participants can be drawn from the population refers to the process of Random sampling. The sample participants are subjected to a treatment by the usage of a random procedure comprises the Random group assignment.
When a researcher wants validate externally then random selection can be used. When a researcher wants to determine the effects of treatment within that group which is known as determination of internal validity then he can opt for Random group assignment.
Answer:
In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.
Explanation:
Random selection is a representation of the sample of people for your research from a community. Random assignment is the assigning of the sample that describes various groups or operations in the study.
Reasons:
- Random sampling enables us to get a sample representative of the community.
- Random assignment enables us to make positive that the only distinction among the various treatment combinations is what needs to study.
- Random assignment is crucial for sound empirical design. With adequately large representations, random assignment performs it unlikely that there are methodical variations among the groups.
Thus we can say in order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.

It's easy if you remember the formulas you learned for the area, diameter,
and circumference of a circle:
-- Area = (pi) (radius)²
-- Diameter = (2) (radius)
-- Circumference = (pi) (diameter)
You know the area. So let's use the first formula to find the circle's radius.
Area = (pi) (radius)²
Divide each side by (pi): Area/pi = (radius)²
Radius = √(area/pi)
Now use the second formula to find the circle's diameter:
Diameter = (2) (radius)
Diameter = 2 √(area/pi)
Now use the third formula to find the circle's circumference:
Circumference = (pi) (diameter)
Circumference = (pi) (2) √(area/pi)
With just a little tweak, that can be written slightly more simply:
Circumference = 2 √(pi x area)
