It is assumed that service times may be described by the negative exponential distribution. A single line would be​ used, and the customer at the front of the line would go to the first available bank teller. If a single teller is​used:​
a) The average time in the line (minutes)​ =
b) The average number in the line​ (customers) =

If a second teller is​ added, the average time a customer spends in the queue​ =
If a second teller is​ added, the average number of customers in the queue​ =  
If a second teller is​ added, the average time a customer spends in the system​ =
If a second teller is​ added, the average number of customers in the system​ =  
If a second teller is​ added, the probability that the bank is empty​ =

dem82 [27]

Answer:

Managers for an organic grocery chain were deciding whether to open a new store in a neighborhood currently unserved by any competitors. One manager felt that the lack of competitive presence was an opportunity to capture the newest customers. Another manager viewed the lack of a competitor in the area as an indicator that the local community may not be interested in organic products. This difference in perspective illustrates the concept of Management.

Explanation:

The art of getting things done through others in an orderly and effective manner is referred to as management. It is the process of getting things done through others with the help of some basic activities like planning, organizing,directing, coordinating and controlling.

Managers were proposing different ideas on how to achieve a goal, which is to decide whether to open a new store in a neighborhood currently unserved by any competitors, thus, the difference in their perspective illustrates the concept of Management.

. Alex has the option to invest in an asset. Her financial advisor has told her there is expected value (utility) of $20,000 on
LiRa [457]

Answer:

A) the probability that the asset will pay well is 51.16% and the probability that it pays poorly is 48.84%.

B) She should not invest in the asset because the expected value = the price asset, there is no expected profit.

Explanation:

There are 2 probable returns:

  1. Asset will pay well = P = $45,000
  2. Asset will pay poorly = 1 - P = $2,000

since the principal = $20,000, and the expected value = $20,000, the expected value equation would be:

45,000p + 2,000(1 - p) = 20,000

45,000 + 2,000 - 2,000p = 20,000

43,000p = 22,000

p = 0.5116 or 51.16%

1 - p = 48.84%
