Answer:
Arrival rate
1 every 3 minutes
1 minute = 1/3 = 0.33
60 minutes = 0.33*60 = 19.8 = 20 per hour
λ = 20 per hour
Service Rate
1 every 2 minutes
1 minutes = 1/2 = 0.5
60 minutes = 0.5*60 = 30 per hour
µ = 30 per hour
a. Utilization of Teller Machine
P = λ / µ
P = 20/30
P = 66.67%
b. Average number of customers in line
Lq = pL = (λ/µ) (λ/µ- λ)
= (20 / 30) (20 / 30 - 20)
= 20/30 * 20 / 10
= 1.33 customers
c. Average number of customers in the system
L = (λ/µ- λ)
= 20 / 30 - 20
= 20 / 10
= 2 customers
d. Average time customer spends in line
Wq = λ/[µ*(µ- λ)]
= 20 / [30 * (30-20)]
= 20 / 30 * 10
= 0.06667 hours or 4 minutes
e. Average time customers spend in the system
W = 1/(µ- λ)
= 1 / 30 - 20
= 1/10
= 0.10 hours or 6 minutes
f. Probability that there are 3 customers in the system
Pn = (1-p)*p^n
= (1 - 20/30) * (20/30)^3
= 0.3333 * 0.296296
= 0.09876
g. Probability that there are two or more customers in the system
= 1 - P(0) - P(1)
= 1 - (1 - 20/30) * (20/30)^0 - (1 - 20/30) * (20/30)^1
= 1 - 1/3 - 2/9
= 4/9
= 0.4444
Answer: $100
Explanation:
From the information, on a Friday night, you have the choice to either go to a Katy Perry concert or a Lady Gaga concert. You won a free ticket to see Katy Perry but you would pay as much as $180 to see Lady Gaga perform, even thought the tickets to her show cost $100.
This illustrates that the person must be willing to pay at least $100 to see Katy Perry. Since the person wa.willing to pay $180 for Lady Gaga even when the tickets were$100, then you should be able to pay at least $100 to see Perry

Company B with the adjusting events above, usually recorded through the adjusting journal, can also be adjusted directly in the trial balance with their effects on the financial statements clearly demonstrated. Expenses have debit accounts while liabilities have credit accounts. Expenses reduce the net income, revenues increase the net income, while liabilities and assets can be reduced or increased as the case may be.
