9-2: 2. Four key marketing judgment fickles are expense ( P ), advertising ( A ), mien ( T ), and fruit condition ( Q ). Consumer exact ( D ) is ruled by these fickles. The simplest standard for describing exact in provisions of these fickles is: 

D = k - pP + aA + tT + qQ 

where k, p, a, t, and q are constants. Discuss the assumptions of this standard. Specifically, how does each fickle rule exact? How do the fickles rule each other? What limitations authority this standard possess? How can it be improved? Solution Tip: This is an disquisition doubt and does not exact anticipation. 

To aid you to arrange this week's ordinance, delight adequate this ordinance merely by satisfaction out the subjoined consideration. All constants k, p, a, t, and q are conjectured to be assured or cipher. 

11-8: Suppose that a car rental production offers security for a week that conciliate require $10 per day. A junior disconnector bender conciliate require $1,500, occasion a main clothing authority require $15,000 in repairs. Without the security, you would be personally qualified for any equivalent. What should you do? Clearly, there are two judgment alternatives: grasp the security or do not grasp the security.
The dubious consequences, or events that authority supervene, are that you would not be concerned in an clothing, that you would be concerned in a disconnector bender, or that you would be concerned in a main clothing. Assume that you researched security assiduity statistics and endow out that the chance of main clothing is 0.05%, and that the chance of a disconnector bender is 0.16%. What is the expected esteem judgment? Would you prefer this? Why or why not? What would be some dubitate ways to evaluate waste? 

12-2: Suppose that the benefit objurgate to a doubt row regularity is 10 customers per hour (exponentially orderly). Analyze how the medium doubt term is expected to veer as the manifestatlon objurgate varies from two to ten customers per hour (exponentially orderly).
