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
Answer:
The second number is a*t/s
Step-by-step explanation:
s/t = a / x Let x be the second number.
sx = at divide by s
x = at/s

An empty swimming pool needs to be filled to the top. The pool is shaped like a cylinder with a diameter of
10 m
and a depth of
1.4 m
. Suppose water is pumped into the pool at a rate of
11 m3
per hour. How many hours will it take to fill the empty pool?
Use the value
3.14
for
π
, and round your answer to the nearest hour. Do not round any intermediate computations.
The formula for the volume of a cylinder is ∏r2h. The problem gives d=10m, so r=5m.
The pool holds (3.14)*52*1.4 m3 = 109.9 m3 of water.
At a rate of 11 m3 per hour:
( 109.9 m3 ) / (11 m3/hr) = 9.990909 hr.
rounding to the nearest hour, this is 10 hours
