Answer:
The answer is "random"
Step-by-step explanation:
The individuals who are selected constitute a random sample of the population. A common example of how to choose a simple random sample is when you write people's names in separated pieces of paper, you put them all in a bag and extract each one until completing the sample size you desire. Each person would have the same chance of being chosen.
Answer:
I Didn't see nothing
Step-by-step explanation:
So I can't help you
9 + n = -2
-9 -9 Get rid of 9 from both sides
n = -2 - 9
n = -11
and since we know now what "x", let's use that in either equation, say the first equation,
another way to do it is by "elimination", depending on the equations, one way may work quicker than the other, in this case, substitution was the simpler one, because the first equation is already solved for "y", so we just grabbed it and plugged it in the 2nd equation.
