**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".

The **range** of the** possible values** of x is:

x > 4

For the **given triangle:**

AB = 4x + 25

BC = 3x - 2

AC = 9x - 5

The **sum** of two of the sides of the triangle should be greater than the **length **of the **third side**

That is:

AC + BC > AB

9x - 5 + 3x - 2 > 4x + 25

12x - 7 > 4x + 25

Collect **like terms**

12x - 4x > 25 + 7

8x > 32

x > 32/8

x > 4

Therefore, the **range** of the** possible values** of x is:

x > 4

**Answer:**

**Step-by-step explanation:**

Answer: 1.8 or 180%

Step-by-step explanation:

The answer is as follows

x = -3

y = 7

There are a few ways to do this but lets do it the following way.

<span>3x + y = -2

y = -x +4 <--- turn this to standard form

</span>

y = -x + 4

x + y = 4

3x + y = -2

x + y = 4 <---- Times this by -3 to cancel out

3x + y = -2

-3(x + y) = 4 * -3

3x + y = -2

-3x -3y = -12

+ y = -2

-3y = -12

-2y = - 14

-2y / -2 = - 14 / -2

y = 7

Now that we found y we can insert 7 into the y position in one of the equation. For instance

y = -x +4

7 = -x + 4

7 = -x + 4

-4 + 7 = -x

3 = -x

x = -3
