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.
Answer:
An angle θ and its reference angle may or may not form supplementary angles.
Step-by-step explanation:
Given: Camilla said that θ and its reference angle are always supplementary angles.
To find: Camilla’s error
Solution:
The reference angle is the smallest angle made from the terminal side of an angle with the x-axis.
Two angles are said to be supplementary if their sum is
An angle θ and its reference angle may or may not form supplementary angles.
The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.
<h3>What is the
average annual rainfall?</h3>
Generally, the equation for the probability is mathematically given as
Therefore
The z score for the probability of 0.979 is 2.034, according to the table of z values.
In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.
In conclusion, The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.
