Answer:
m = -2
Step-by-step explanation:
Slope Formula: 
Simply plug in your coordinates:
m = (-2 - 2)/(6 - 4)
m = -4/2
m = -2
If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.
In this case the probability of the event is p=20/69.
Then, the probability of the event not happening is:

Answer: the probability of the event not happening is 49/69.
You divide $1.39 by $5.68 which is about 4.08
I think
Adjacent angles, and x = 21.
90 - 69 = 21.
