Answer:
2.86% probability that there are exactly 3 crimes during the next hour
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour.
So 
What is the probability that there are exactly 3 crimes during the next hour
This is P(X = 3).


2.86% probability that there are exactly 3 crimes during the next hour
The y-intercept is 4.
If you have x-4y=-16, in slope intercept form it is y=1/4x+4.

Answer:
160,000,000
Step-by-step explanation:
hello so this one is pretty simple ill give a quick walk through of what i did...
first i took 10x10x10 for 1,000 then X that by 8= 8,000
second we do 10x10x10x10 for 10,000 then X that by 2 for 20,000 then 20,00 X 8,000= 160,000,000
