The correct is going to be “Identify the Choices”.
Hope this helps! :))
Answer:
75.76% probability that there will be 10 or more customers at this bank in one 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 interval.
A bank gets an average of 12 customers per hour.
This means that
Find the probability that there will be 10 or more customers at this bank in one hour.
Either there are less than 10 customers, or there are 10 or more. The sum of the probabilities of these events is 1. Then
We want
Then
In which
So
Then
75.76% probability that there will be 10 or more customers at this bank in one hour.
For this case we must find a linear equation of the form:
Where,
m: slope of the line
b: cutting point with vertical axis.
For the slope we have the following equation:
Substituting values we have:
We observe that the slope of the line is not defined.
Therefore, the line is vertical.
Thus, the equation of the line is given by:
Answer:
The equation of the line is given by:
