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.
Answer:


Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 500
Standard Deviation, σ = 100
We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.64
P(X<x) = 0.64
Calculation the value from standard normal z table, we have, 


Answer:
Below.
Step-by-step explanation:
Angle 1 = (3/(3+4+5) * 180 = 3/12 * 180
= 45 degrees.
Angle 2 = 4/12 * 180 = 60 degrees.
Angle 3 = 5/12 * 180 = 75 degrees.
Answer: I don’t think there is such a line. A Line that passes through the point (3,-9) must have a positive slope, unlike the line y=-5x-2, which has a negative slope. If a line where to go through (3,-9), is would intersect the line you presented.
