Answer:
{1, 16, 36}
Step-by-step explanation:
Put the numbers in for x and see what the f(x)-values are.
(-5-1)^2 = (-6)^2 = 36
(0-1)^2 = (-1)^2 = 1
(5-1)^2 = 4^2 = 16
The range is the set of values {1, 16, 36}.
The LCM for 6 and 18 is 18
Hope this helps.
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.
