The field of a new soccer stadium is watered by three individual sprinkler systems, as shown by the A, B, and C regions in the figure below. Each sprinkler system is controlled by exactly one of three on-off valves in an underground maintenance room, and each sprinkler system can be turned on without turning on the other two systems. Each of the valves is presently in the off position, and the field is dry. The valves have not been labeled, so you do not know which valve controls which sprinkler system. You want to correctly label the valves as A, B, and C. you also want to do it by making only one trip up

STAR Co. provides paper to smaller companies with volumes that are not large enough to warrant dealing directly with the paper mill. STAR receives 100-feet-wide paper rolls from the mill and cuts the rolls into smaller rolls of widths 12, 15, and 30 feet. The demands for these widths vary from week to week. The following cutting patterns have been established. Min s.t. 12-ft Pattern Number 15-ft 30-ft 1 2 P1, P2, P3 P4 P5 ≥ 0 3 4 5 12-ft 15-ft 30-ft Trim Loss (ft) 0 0 8 3 7 6 0 0 0 1 C 3 0 2 0 10 Trim loss is the leftover paper from a pattern (e.g., for pattern 4, 3(12) + 0(15) + 2(30) = 96 feet used results in 100 - 96 = 4 foot of trim loss). Orders in hand for the coming week are 5,680 12- foot rolls, 1,690 15-foot rolls, and 3,360 30-foot rolls. Any of the three types of rolls produced in excess of the orders in hand will be sold on the open market at the selling price. No inventory is held. 10 Formulate an integer programming model that will determine how many 100-foot rolls to cut…

PROBLEM 03: The Jokia Cell Phone Company manufactures two models of cell phones - the Wombat and the Sloth. Each Wombat phone uses 2.5 ounces of gold leaf and 3 ounces of plastic, whereas each Sloth phone uses 2 ounces of gold leaf and 2 ounces of plastic. Each day, the company has only 370 ounces of gold leaf and 420 ounces of plastic to be used for making cell phones. If the company makes the correct number of each type of phone on a given day to use up all of the available gold leaf and plastic, how many Wombat phones will be made? A) 60 B) 100 C) 50 D) 90 E) 110 N) none of the above

This is a practice exam.  I would like to know how to slove usign excel or megastat Wenton Powersports produces dune buggies. They have three assembly lines, “Razor,” “Blazer,” and “Tracer,” named after the particular dune buggy models produced on those lines. Each assembly line was originally designed using the same target production rate. However, over the years, various changes have been made to the lines. Accordingly, management wishes to determine whether the assembly lines are still operating at the same average hourly production rate. Production data (in dune buggies/hour) for the last eight hours are as follows. (You may find it useful to reference the F table.)   Razor   Blazer   Tracer   11       10       9     10       8       9     8       11       10     10       9       9     9       11       8     9       10       7     12       11       8     12       8       9         Click here for the Excel Data File   a.
