Answer:

C.) Stratified random

Step-by-step explanation:

Definitions:

<em>C.)</em>Stratified random sample: The population is first split into groups. The overall sample consists of some members from every group. The members from each group are chosen randomly.

A.) Convenience sample: The researcher chooses a sample that is readily available in some non-random way.

B.) Simple random sample: Every member and set of members has an equal chance of being included in the sample. Technology, random number generators, or some other sort of chance process is needed to get a simple random sample.

D.) Systematic random sample: Members of the population are put in some order. A starting point is selected at random, and every ninth member is selected to be in the sample.

Hope this helps : )

Please please help please
il63 [147K]

Answer:

6 times larger

Step-by-step explanation:

First, find the area of both.

Mary: 4*5.5=22

Lisa: 24*5.5=132

Then find what multiplied by 22 would equal 132. This is easy because it's a multiple-choice question.

22*20=440, so A is incorrect

We already know they are not equal, so then B can be crossed out

22*3=66, C would be incorrect

Leaving the only choice left to be the correct answer

22*6=132

3x+2y=3 Get y alone.
Kazeer [188]
3x + 2y = 3. subtract 3x from both sides, so you get 2y = -3x + 3 . then you divide by 2 to both sides , so you get y = -3/2x + 3/2 .

-10x+25=5
