Answer:
1/59049
Step-by-step explanation:
I know! It's kind if annoying tbh...
1. Distribute the -2x with the (x+3)
2.Multiply (x+1) and (x-2) which is (x2- x -2)
So far it should look like (-2x^2 -6x) - (x^2-x-2)
3. Distribute out the negative
Should look like this -2x^2 -6x - x^2+x+2
4. Lastly combine like terms
Your result should be:
-3x^2 - 5x + 2
Hope this helps!

It becomes lower
Step-by-step explanation:
This is because as the lowest value becomes larger, <em>one of the values becomes closer to the mean</em>, and as more numbers are closer to the mean, the standard deviation becomes lower.
