Answer:
On average how many requests are in the first department (including those who are waiting) is 1.32.
Step-by-step explanation:
In this case, use the Little's law of queuing theory.
The Little's law states that the average number of customers in a fixed system (L) is equal to the average effective arrival rate (λ) multiplied by the average time a customer spends in the system (W).
The number of requests per hour in the 1st department is, λ₁ = 4.
It is provided that 20% are rejected directly by the 1st department without going into the 2nd department.
Then the number of requests per hour is, λ₂ =
The average time a customer spends in the 1st department,
W₁ = 20 minutes = 0.33 hours.
The average time a customer spends in the 1st department,
W₂ = 60 minutes = 1 hour
On average how many requests are in the first department (including those who are waiting) is:
<em>L</em> = λ₁ × W₁
= 4 × 0.33
= 1.32
Thus, on average how many requests are in the first department (including those who are waiting) is 1.32.
For this case, the first thing we must do is define variables.
We have then:
x: number of cabins
y: number of campers
We now write the equation that models the problem:
We know that there are 148 campers.
Therefore, substituting y = 148 in the given equation we have:
From here, we clear the value of x:
Therefore, the number of full cabins is:
Answer:
The number of full cabins is:
