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.
Answer is 54^2.
since there are triangles in this one, it is easier to do this. all you have to do is make boxes in and since there are angles, outside the lines. like this picture.
the orange is 1
red and dotted is 2
blue is 3
purple is 4(a regular box which should be easy to count.
all you have to do is add up all the boxes within the boundaries.
boundary 1: 12
boundary 2: 18
boundary 3: 6
boundary 4: 36
now when the boundary has a triangle in it (1, 2, & 3) divide the number you got in half or 2.
boundary 1: 6
boundary 2: 9
boundary 3: 3
the ractangle box doesn't not get divided.
boundary 1: 6
boundary 2: 9
boundary 3: 3
boundary 4: 36
add all the numbers you got now for each boundary and that would be your area squared.
6+9+3+36=54^2
so your final answer is 54^2.
i hope this helps you.
