Answer: stratified
Step-by-step explanation:
In stratified sampling, you divide the population into subgroups, or strata, with similar characteristics, like here we have divided the population into subgroups that depend on their political alignment. This is used when you can expect that the results have a noticeable variation between the different subgroups. Usually, you want to have the same number of population for eac subgroup, but sometimes it is hard for different reasons (not enough people in one subgroup, for example)
In cluster sampling we also use subgroups, but the subgroup itself is the unit of the sampling, while in this case, we are randomly selecting individuals of the given subgroups.
So this would be a "stratified sampling".
Answer:
the volume of a cube is equal to s3, where s is the length of a given side of the cube. Since the sides of a cube are all the same, the surface area of the cube is equal to 6 times the area of one face.
Answer:
0.
Step-by-step explanation:
sin 12 = cos(90 - 12) = cos 78 so the answer is 0.
In all the answers we are solving for x. That means x needs to be by itself.
2x + 4a = 10
Subtract 4a.
2x = 10 - 4a
Divide by 2.
x = 5 - 2a
Answer is....
D. x=5-2a
Answer:
I think it's
D. AC/GI = BC/HI
Step-by-step explanation:
Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.
AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.
I think.
I guess.
I don't know.
I didn't pay attention, tbh. LOL
