Answer:
Mid point is: (2.8;4.9)
Step-by-step explanation:
To find midpoint of a line segment we can use the general equation:
Where the point of the line are: (x₁;y₁) and (x₂;y₂).
In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:
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
