Exam 2 Preparation Guidelines February 24‚ 2013 Exam 2 is scheduled for Tuesday 3/5. Coverage will include material identified on the syllabus through 2/28. The exam will be comprised of two parts: (1) multiple choice questions (and possibly a few true/false)‚ (2) short answers. The weight between parts I and II will likely be in the neighborhood of 50-50. I’m guessing that 80% or more of the exam points will based on content since exam 1 (i.e.‚ content in chapters 8‚ 10‚ and 11). The exam is closed

was widely praised by both blacks and whites‚ although it was not long before critics of Washington’s position emerged to challenge his leadership. Early complaints about Washington’s accommodation to the white South came from the black scholar W. E. B. Du Bois and others. But until he died in 1915‚ Washington was the most influential black leader in America‚ and the most famous black celebrity in the country‚ an adviser to presidents and representative to European heads of state. His autobiography

Solver is a tool to model and solve linear and nonlinear programming problems. To access it‚ open Excel‚ choose the tab “Data” and select “Solver” from the “Analysis” group. If it is not there‚ you have to install it‚ by clicking the “File” tab (or the Office button)‚ then “Options”‚ then “Add-Ins”‚ and then “Manage Add-Ins”. Check “Solver” there. To solve the model‚ you have to first program in on a spreadsheet. In the attached “excel-example.xls” we solve the linear programming problem max 3x1 + 2x2

In order to understand this topic‚ continuous-time system comes into different classifications which are the following: * Linear and Nonlinear Systems A system is linear if it follows the superposition principle. Also‚ it satisfies the additivity and homogeneity properties. Hence‚ if a system does not satisfy either of the two properties‚ it is said to be a non-linear system. * Time-varying and Time-Invariant Systems A system is said to be

Integer Programming 9 The linear-programming models that have been discussed thus far all have been continuous‚ in the sense that decision variables are allowed to be fractional. Often this is a realistic assumption. For instance‚ we might 3 easily produce 102 4 gallons of a divisible good such as wine. It also might be reasonable to accept a solution 1 giving an hourly production of automobiles at 58 2 if the model were based upon average hourly production‚ and the production had the interpretation

modal class is the class with the largest number of observations) - A unimodal histogram is one with single peak. A bimodal histogram is one with two peaks‚ not necessarily equal in height 4. Bell shape – A special type of symmetric unimodal histogram. B. Stem-and-leaf Display ~ One of the drawback of the histogram is that we lose potentially useful information by classifying the observations. Stem-and-Leaf method developed by statistician John Tukey overcomes this loss to some extent. The advantage
