Given that,
An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.
Also it takes 209 seconds at an altitude of 8848 m.
To find,
The domain of T.
Solution,
Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :
Therefore, this is the required solution.
Answer:
It takes on average 3 minutes to service each student.
Step-by-step explanation:
In queueing problem, an M/M/1 queue model is an arrangement with a single queue, where arrivals at the queue are approximated by a Poisson distribution with mean λ and the service times follows an exponential distribution with mean μ.
The mean number of arrivals in this system is given by:
Here the variable ρ is defined as:
From the average number of arrivals in the system, we can calculate the average number of arrivals in the queue by subtracting the average number of arrivals in service.
That is,
The information provided is:
The average number of arrivals of customers is, λ = 12 students/hour.
The average service rate of a single server is, μ = 20 students/hour.
The average of an exponential distribution is:
Compute the average time it takes to service one student as follows:
Thus, it takes on average 3 minutes to service each student.
