24. The regression model ABOVE is: 25. According to the regression model ABOVE, when the S&P 500 index value is 1,000, the forecasted Halliburton stock price is: The S&P index value must be ________ for the Halliburton stock to be priced at \$24.75 26. Corporate AAA bond interest rates for 12 consecutive months are 9.5%, 9.3%, 9.4%, 9.6%, 9.8%, 9.7%, 9.8%, 10.5%, 9.9%, 9.7%, 9.6% and 9.6%. The three-month weighted moving average forecast (with weights 0.2, 0.4 and 0.4 - from oldest to most recent respectively) for the next month, rounded to two decimal places, is: 10
Questions 27 & 28 apply to this information: Quill Manufacturing Business makes two models of marking pens. An unlabeled graph for this problem and the requirements for each lot of pens in the three manufacturing departments are given below. All three departments are necessary in the production of both types of pens. The profit for either kind of pen is \$1000 per lot. An unlabeled graph for this problem is given below. The dotted line represents the objective function line. Fliptop Model Tiptop Model Available production hrs. Ink Assembly 3 4 36 Molding Time 5 4 40 Plastic 5 2 30 0 5 10 15 0 5 10 15 27. What is the optimal production quantity of the Fliptop model? A. 5 lots B. 4 lots C. 2 lots D. 7 lots E. 6 lots 28.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
