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:
b) Component
Explanation:
Since in the question it is mentioned that the neha has written a report in which the profits of three fashion design houses could be compared
So in this situation, the component organizational method could help for knowing the strategic and the operational information so that it would be easy for comparing the profits between these three fashion houses
Therefore the option b is correct
What Carlos and his client should consider before finalizing these deadlines is whether the deadlines are realistic.
<h3>How important are deadlines in a sales contract?</h3>
The deadlines refer to the obligations of a buyer in a negotiation, being mandatory and legal compliance. But it is essential that the stipulated deadlines are realistic in relation to the contract clauses, offering benefits to both parties involved in the negotiation.
Therefore, the deadlines provided for in a contract must be analyzed and discussed if the requirements are unrealistic and cannot be effectively fulfilled for the seller and the customer.

Answer:
FV= $17,105
Explanation:
Giving the following information:
Annual investment= $5,500
Interest rate= 11%
Number of periods= 3
I will assume that the annual deposit is at the end of the year.
<u>To calculate the future value, we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {5,500*[(1.11^2) - 1]} / 0.11 + 5,500
FV= $17,105
