Marty's barber shop has one barber. customers have an arrival rate of 2.3 customers per hour, and haircuts are given with a service rate of 5 per hour. use the poisson arrivals and exponential service times model to answer the following questions: 1. what is the probability that one customer is receiving a haircut and one customer is waiting?
2. what is the probability that one customer is receiving a haircut and two customers are waiting?
3. what is the probability that more than two customers are waiting?

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
