3.Atlantic Video, a small video rental store in Los Angeles, is open 24 hours a day, and experiences customers arriving around the clock. A recent analysis done by the store manager indicates that there are 30 customers arriving every hour, with a standard deviation of inter-arrival times of 2 minutes. This arrival pattern is consistent and is independent of the time of day. The checkout is currently operated by one employee, who needs on average 1.7 minutes to check out a customer. The standard deviation of this check-out time is 3 minutes, primarily as a result of customers taking home different numbers of videos. a.If you assume that every customer rents at least one video (i.e., has to go to the check-out), what is the average time a customer has to wait in line before getting served by the checkout employee, not including the actual checkout time?b.If there are no customers requiring checkout, the employee is sorting returned videos, of which there are always plenty waiting to be sorted. How many videos can the employee sort over an 8-hour shift (assume no breaks) if it takes exactly 1.5 minutes to sort a single video? c.What is the average number of customers who are at the checkout desk, either waiting or currently being served? d.Now assume for this question only that 10 percent of the customers do not rent a video at all and therefore do not have to go through checkout. What is the average time a customer has to wait in line before getting served by the checkout employee, not including the actual checkout time? Assume that the coefficient of variation for the arrival process remains the same as before.e.As a special service, the store offers free popcorn and sodas for customers waiting in line at the checkout desk. (Note: The person who is currently being served is too busy with paying to eat or drink.) The store owner estimates that every minute of customer waiting time costs the store 75 cents because of the consumed food. What is the optimal number of employees at checkout? Assume an hourly wage rate of $10 per hour. (Hint: Compare the costs of employing 1,2,3 and 4 workers and then pick the best.)

Provide a 9 pages analysis while answering the following question: Cultural Variation: Considerations and Implications by Dov Cohen. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Similar environments can produce quite different social systems, while similar cultures may exist in different environments. Examining cultural variations in terms of game theory, dynamic systems theory, evolutionary biology, political science and economics, Cohen argues (p.451) that constant interactions and adjustments of actors within a social system may lead to multiple social patterns or equilibriums, mapping onto definite cultural systems of norms, rules, and sets of common meanings and expectations. He also proposes that in order to better understand the ways how cultures are created and recreated one should consider them in terms of mutual interdependence, historical development and meaning, game theory principles, and crucial choice points and junctures. The author’s suggestion is that the cultural system processes too complex to be viewed only as a functional response to the environmental impact. Cohen also offers that the emergence and stability of cultural traits should be examined within four types of niches shaping cultural patterns, such as physical, social, intercultural, and intercultural.

Part 1 of the article deals with the traditional approach to the emergence of different cultural adaptations due to different ecologies and economies. Being widely researched and proved by scholars, this fact is undoubtedly a starting point of cultural variations studies. Numerous examples may be found. For instance, the works of anthropologist David Gilmore (1990) demonstrate that the conceptions of masculinity depend on the environmental conditions of the social group. In cases, where the conditions of life do not demand males to fulfill their major functions of protecting, procreating, and providing, one may observe relatively androgynous sex roles, while harsher environments and scarcer resources lead to more distinct male functions and stressed manhood.
