Consider an espresso stand with a single barista. Customers arrive at the stand at the rate of 28 per hour according to a Poisso
Snowcat [4.5K]

Answer:

The average number of customers in the system is 3.2

Step-by-step explanation:

The average number of customes in the system is given by:

L = \frac{\lambda^{2}}{\mu(\mu - \lambda)}

In which

\lambda is the number of arirvals per time period

\mu is the average number of people being served per period.

The number of arrivals is modeled by the Poisson distribution, while the service time is modeled by the exponential distribution.

Customers arrive at the stand at the rate of 28 per hour

This means that \lambda = 28

Service times are exponentially distributed with a service rate of 35 customers per hour.

This means that \mu = 35. So

The average number of customers in the system (i.e., waiting and being served) is

L = \frac{\lambda^{2}}{\mu(\mu - \lambda)}

L = \frac{28^{2}}{35(35 - 28)} = 3.2

The average number of customers in the system is 3.2

on the first play of a game , a football team gained 23 yards and then lost 10 yards due to penalty during the second play the t
zepelin [54]
-1 Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).
Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:
20
+
5
=
25
So the second play they get sacked deep and lose 6 yards. So we subtract 6:
25
−
6
=
19
So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:
19
−
20
=
−
1
and this makes sense because we know we advanced 5 and fell back 6
