Professor Goodheart always gives two midterms in his communications class. He only uses the higher of the two scores a student gets on the midterms when he calculates the course grade. (Adapted from Varian Workouts)(a)You want to maximize your course grade. Let x1be your score on the midterm 1 and x2beyour score on midterm 2. Which combination do you prefer, x1 = 20 and x2= 70 or x1 = 60and x2= 60?(b) Draw a graph showing an indifference curve of the all the combination of scores that you like exactly as much as x1 = 20 and x2= 70. Also draw an indifference curve showing all the combinations you like as much as x1= 60 and x2= 60.(c)Do you have convex preferences over these combinations?

(d) You are also taking a course with Professor Stern who also gives two midterms. Instead of discarding the lower grade, he discards the higher one. Let x1be the score on the first midterm, and x2be the score on the second midterm. Which combination do you prefer, x1= 20 and x2= 70 or x1= 60 and x2= 50?(e)Draw a graph showing an indifference curve of the all the combination of scores that you like exactly as much as x1= 20 and x2= 70. Also draw an indifference curve showing all the combinations you like as much as x1= 60 and x2= 50.

The beach dude (bd) employs a legion of current and former surfers as salespeople who push its surfing-oriented products to various customers (usually retail outlets). this case describes bd's sales and collection process. each bd salesperson works with a specific group of customers throughout the year. in fact, they often surf with their customers to try out the latest surf gear. the bd salespeople act laid-back, but they work hard for their sales. each sale often involves hours of surfing with their customers while the customers sample all the latest surf wear. because bd makes the best surfing products, the customers look forward to the visits from the bd salespeople. and they often buy a lot of gear. each sale is identified by a unique invoice number and usually involves many different products. customers pay for each sale in full within 30 days, but they can combine payments for multiple sales. bd manages its clothing inventory by item (e. g., xl bd surfer logo t-shirts), identified by product number, but it also classifies the items by clothing line (the lines are differentiated by price points as well as the intended use of the clothing, e. g., surfing products, casual wear, . draw a uml class diagram that describes the beach dudes sales and collection process. b. using microsoft access, implement a relational database from your uml class diagram. identify at least three fields per table. c. describe how you would use the relational database to determine the beach dude’s accounts receivable.
