Complete Question
A waiting line problem has an average of 250 arrivals per eight hour day. Suppose there are several servers, and each has an average service time of 8 minutes. (Assume Poisson arrivals and exponential service times.)
What is the average service rate of a server per hour?
Answer:
7½ arrivals per hour
Explanation:
Given
Arrivals = 250 arrivals per 8 hour day
Service Time of Servers = 8 minutes
The service time of Servers is given as 8 minutes.
This means that; on average, a server will attend to 1 arrival in every 8 minutes.
Calculating this per hour;
Average service rate of a server per hour = Service Rate * 1 hour per hour
Average service rate of a server per hour = 1 arrival per 8 minutes * 1 hour per hour
(1 hour = 60 minutes);
So, we have.
Average service rate of a server per hour = 1/8minutes * 60minutes/hour
= ⅛ * 60 arrivals/hour
= 60/8 arrivals/hour
= 7½ arrivals per hour
Answer:
Biomimicry.
Explanation:
"Closed-loop" production seeks to integrate what is presently waste back into production. In an ideal situation, the waste of one firm becomes the resource of another, and such synergies can create eco-industrial parks. This principle is often referred to as biomimicry.
Biomimicry can be defined as a technological-oriented systems or model which is typically focused on the application of nature's elements or processes, and lessons into proper use for the purpose of solving real-life problems. Some examples of biomimicry are Tree-climbing robot mimics inch worms, Gecko climbing feet, Bird skull shoe, Armadillo backpack etc.
Answer:
B. No, because the advertisements are an invitation to bid.
Explanation:
An advert is not legally binding as it is just a means to capture consumer attention and convince them to buy a product or service.
Advertisements are merely considered as invitations to bid so the one made by Neti-pot Co is misleading because anybody reading it will immediately assume if a consumer takes the product the way it is advertised and begin to get side effects, the company will really give out the $100 promised.

Answer:
Increase in tax rate will reduce income form bond but will not affect the benefits derivable from the purchase of the new luxury auto.
Explanation:
First, a look at the after tax rates for when tax is 35% and when it is increased to 50%.
Step 1: Compute the after tax rate when tax is 35%
=Interest rate x (1-tax rate)
= 0.08 x (1- 0.35)
-5.2%
Step 2: Compute the after tax rate when tax is increased to 50%
= Interest rate x (1- tax rate)
= 0.08 x (1-0.5)
=4%
The first outcome is that an increase in tax rate leads to a decrease in income. Meaning an increased tax rate reduces the income from the bonds.
However, an increase in tax rate although it will affect the income will have no effect on the new luxury condo, that Ms V wants to buy. This is because, the benefits Ms V will get from the auto cannot be taxed as compared with the interest on the bond.
Hence, it becomes easier for Ms V to buy the luxury auto than invest in bonds if the tax rate should increase
