Answer:
A) 1.79
b) 71%
c) 0.75 minutes
d) 0.537 minutes
e) 0.343, 0.240 , 0.1681
Explanation:
L = average number of customers in the system ( 200 / 80 ) = 2.5
a = poission distribution per hour = 200
b = service rate of cashier = 280
A) average number of moviegoers waiting in line to purchase ticket
Lq = L - 
= 2.5 - (200/280) = 2.5 - 0.71 = 1.79
B) percentage of cashier been busy
p = a/b = 0.71 = 71%
C) average time spent by a customer in the system
w = L / a = 2.5 / 200 = 0.0125 hours = 0.75 minutes
D) average time spent waiting in line to get to the ticket window ?
W2 = Lq / a = 1.79 / 200 = 0.00895 hours = 0.537 minutes
E) probabilities of people in the system
i) more than two people
p ( x ≥ 2 ) = 1 - ( p0 + p1 + p2 ) = 1 - 0.657 = 0.343
more than three people
ii) p ( x ≥ 3 ) = 1 - (p0 + p1 + p2 + p3 ) = 1 - 0.7599 = 0.240
iii) more than four people
p ( x ≥ 4 ) = 1 - ( p0 - p1 + p2 + p3 + p4 ) = 1 - 0.8319 = 0.1681
About ninety percent of worldwide stocks of tuna, cod, and other large ocean fishes have disappeared in the last 50 years.
Despite being present in every ocean in the world, tuna and other fishes have started disappearing. The North Atlantic, South Atlantic, as well as the Mediterranean Sea, have the worst conditions for the majority of fish species.
Bluefin, albacore, and yellowfin tuna stocks have drastically decreased as a result of years of overfishing for American and European markets. Although the Atlantic fisheries is heavily regulated, illegal fishing off the shore of coastal seas persists, particularly close to Africa, where impoverished nations cannot afford the patrols required to execute the law.
However, tuna populations cod and other large fish oceans are declining even in the world's largest oceans, and some face extinction due to the continuous pressure of intensive commercial fishing.

Answer:
1. Real risk-free rate.
2. Nominal risk free-rate.
3. Inflation premium.
4. Liquidity risk premium.
5. Liquidity risk premium.
6. Maturity risk premium.
Explanation:
Market interest rates can be defined as the amount of interests (money) paid by an individual on deposits and other financial securities or investments. The factors that typically affect the market interest rate known as the determinant of market interest rates are;
1. This is the rate on short-term U.S. Treasury securities, assuming there is no inflation: Real risk-free rate r*
2. It is calculated by adding the inflation premium to r*: Nominal risk free rate.
3. This is the premium added to the real risk-free rate to compensate for a decrease in purchasing power over time: Inflation premium.
4. This is the premium added as a compensation for the risk that an investor will not get paid in full: Liquidity risk premium.
5. This premium is added when a security lacks marketability, because it cannot be bought and sold quickly without losing value: Liquidity risk premium.
6. This is the premium that reflects the risk associated with changes in interest rates for a long-term security: Maturity risk premium.
