Answer:
(a) 0.01029 (b) 4.167 customers (c) 0.4167 hours or 25 minutes (d) 0.5 hours or 30 minutes
Step-by-step explanation:
With an arrival time of 6 minutes, λ=10 clients/hour.
With a service time of 5 minutes per transaction, μ=12 transactions/hour.
(a) The probability of 3 or fewer customers arriving in one hour is
P(C<=3)=P(1)+P(2)+P(3)
(b) The average number of customers waiting at any point in time (Lq) can be calculated as
(c) The average time waiting in the system (Wq) can be calculated as
(d) The average time in the system (W), waiting and service, can be calculated as
D, “it is one-half the area of a rectangle of length 2 units and width 4 units.”
HOPE THIS HELPS!!!
Bearing in mind that, if you multiply, any integer whatsoever by 2, you end up with a even integer, 17*2, or 19*2, 88*2 you name it, you get an even number
now, you can get an odd integer by simply going from an even integer, back or forth, so if you have an even number of say 24, 24 - 1, 23, 24+1, 25, 23 and 25 are the odd ones next to 24
so.. let's pick some number, let's say hmm "a", we know 2*a is even, so 2a, thus, 2a +1 or 2a -1 is an odd one.... let's use hmm 2a + 1 as our first odd integer
to jump from an odd integer to another, you simply add 2, 3+2, 5, 5+2, 7 and so on
so... our first one is 2a + 1, so the next consecutive one, will then be (2a+1)+2
and next consecutive after that is (2a+1+2)+2
so our three consecutive odd integers are then
2a + 1
2a + 3
2a + 5
now, 4 times the middle is 4(2a+3)
the sum of the first and last is (2a+1) + (2a+5)
now, two more than that is just (2a+1) + (2a+5) + 2
thus
4(2a + 3) = (2a + 1) + (2a + 5) + 2
solve for "a"
