What are the answer choices, if you have any?
Answer:
Step-by-step explanation:
In this case we can calculate the probability using the binomial probability formula
Where p is the probability of obtaining a "favorable outcome " x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.
(a) exactly five
This is:
So:
(b) at least six
This is:
(c) less than four
This is:
A straight line = 180 degrees.
Subtract the 2 known angles from 180:
180 - 112 - 38 = 30 degrees
It is B. Because perpendicular is opposite reciprocal
4 + h = 68
h = 68 - 4
h = 64
