A suitable probability calculator can tell you the probability is about 6.7%.
_____
The standard deviation of the distribution of sample means is the population standard deviation (6) divided by the square root of the sample size (√144=12). Thus, your threshold is about (19.25-20)/(6/12) = -1.5 standard deviations from the mean.
The formula of a slope:
We have the points (1, 4) and (1, -3). Substitute:
DIVISION BY ZERO!!!
Answer: The slope is undefined.
It's a vertical line x = 1.

In the second equation it is actually going on to be +2x^2 -4x-2 then your going to combine like terms. So it will be 5x^2-10. Because he 4x’s are going to eliminate each other.
