I’m a bit confused confused, but the answer may be -2x^3 + 2x^2 - 2x +2
Work:
To solve this, take the equation for q and the equation for r, and multiply them together.
Use the distributive property to multiply them.
I’m not sure if this is right or not, so pls don’t get mad if it isn’t.
Thank you! :)
A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.
Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.
Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.
-4 as a fraction would be -4/1.
So start at (5,3), go down 4 and over 1, repeatedly and you got it.
**Just remember the rise over run can be confusing with negative slopes.**
6PM I believe because 3:30 + 30 min = 4:00 + 2 hr (2:00) = 6:00!
Hope this helped and sorry if it’s incorrect!

Answer:
3.5
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
We know that the standard error of the sampling distribution of sample means is
Standard error=standard deviation/√n
√n=standard deviation/Standard error
n=(standard deviation/Standard error)²
We are given that standard deviation=5 and standard error=1. So,
n=(5/1)²
n=5²
n=25.
Thus, the required sample size is 25.
