Queuing theory had its beginning in 1909 with the research work of a danish engineer named a. k. erlang. in queuing problems, the number of arrivals per unit of time can be estimated by the . poisson refers to customers who refuse to join the waiting line because it is too long to suit their needs or interests. balking a queue is unlimited when its size is unrestricted, as in the case of a tollbooth serving automobiles jockeying occurs when customers switch between queues if they think they will get served faster by doing so.

Suppose a stock had an initial price of $65 per share, paid a dividend of $1.45 per share during the year, and had an ending share price of $58. a, compute the percentage total return. (a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) b. what was the dividend yield and the capital gains yield? (a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e. g., 32.16.)
