====================================================
Here are the steps to find the inverse
Now this would be the answer if our original domain was
However, that's not the case and instead our domain is
Reflecting any (x,y) point in this domain restriction, over the the line y = x, will have us land on a point with a negative y value. This is because the inverse will swap the x and y values.
Therefore, the inverse function must ultimately be negative.
Currently is positive since the result of any square root is never negative.
To fix this, we stick a negative out front to get the final answer being
Right. The first 5 is in the tenths place, the second five is in the hundredths, and the third one is in the thousandths. I'd like to think that if you take away (divide 1000 by ten) a tenth from the thousandths, that would leave you with the 5 in the middle being one tenth the value of the five to its right. (I'm not sure if this is correct or not, i'm just making an assumption). I would check with someone to make sure
Answer:
Step-by-step explanation:
A nationally known cosmetics company hires a market research firm to test new formulations of moisturizer. Using their extensive list of possible subjects,
the market researchers first divide the subjects into 5 age groups and then randomly select names from each age group to participate in a study. This is an
example of
systematic sampling
a simple random sample
stratified sampling
cluster sampling
