Answer:
0.713 = 71.3% probability that the county office will get more than 0 calls in a 15 minute period.
Step-by-step explanation:
We have the mean during a time-period, which means that the Poisson distribution is used to solve this question.
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 county office gets an average of 10 calls in a 2 hour time period.
10 calls each 120 minutes, which means that the mean for n minutes is:
15 minute period:
This means that
What is the probability that the county office will get more than 0 calls in a 15 minute period?
This is:
In which
So
0.713 = 71.3% probability that the county office will get more than 0 calls in a 15 minute period.
Yes i totally agree on what going on here

Answer:
Zero-elevation surface is a vertical datum that is used to describe a surface, such as that of a planet. The value of this datum is usually adopted by statute. This elevation is used, for example, to build a texture map from an agreed surface, such as a spheroid with dimensions defined by a mean surface gravity.
