DocumentCourse Purpose
Increase studentís problem solving and analytical capability while mastering a multitude of subjects under the topic of "finite math." Additionally, this course will satisfy studentsí General Education math requirement.

DocumentCourse Goals
At the end of this course the student will be able to:
1. Determine if given data fits a linear model
2. Find the equation of the best-fit line and correlation coefficient using the graphing calculator
3. Predict values using the best-fit line
4. Analyze results from regression analysis
5. Solve linear programming problems graphically
6. Solve systems of equations using Gauss-Jordan
7. Perform set operations
8. Analyze data using Venn diagrams
9. Analyze data using Tree Diagrams
10. Define basic probability terms
11. Compute probabilities of equally likely events
12. Create probability distributions
13. Compute probabilities using the basic rules of probability
14. Use probability distributions to compute the expected value of the distribution
15. Compute conditional probabilities.
16. Determine if two events are independent
17. Create frequency distributions and histograms.
18. Compute mean, mode, median
19. Compute variance and standard deviation using the graphing calculator
20. Analyze statistical data
21. Compute simple and compound interest parameters
22. Compute annuity and loan values
23. Use the graphing calculator to solve various types of problems.

DocumentCourse Information                                                    (1) Prerequisites: A grade of 'C' or better in MAT 101 or 102, or an appropriate placement test score.
(2) Cheating: Any studen
t guilty of cheating will be given a '0' on that assignment, final, or test. Additionally, the incident will be formally reported to the Vice President for Student Services. See the Student Handbook for additional information.
(3) Tutoring Center: Tutors are available in the tutoring center if you wish to use them. Call 301-322-0748 for an appointment.
(4) Test Administration: All tests will be taken in the Testing Center (Accokeek Hall--2nd floor). Go to to learn about the testing center rules and regulations and operating hours.
(5) Course Pace: It is imperative that you do not fall behind in this course; the short 8 weeks does not allow any make-up time.
(6) Practice Problems: Suggested problems for you to do are provided for each section of the book (that we will cover) in accordance with the syllabus. Even though the answers/solutions to these problems will not be collected, you must be able to successfully complete these problems, along with the examples in the books, in order to be prepared for the graded assignments/tests and to master the course. Most of the answers to these problems are in the back of the textbook, and many of the problems are worked for you in the solutions manual.

DocumentGrading Policies
(1) Gr
ades: Your total score (out of 800 points) on tests, assignments, a project, and the final exam will determine your grade. I reserve the right to use (in a positive manner only) a "fudge factor" based on your participation in the course, especially the assistance you may inadvertently give others by posting good questions or suggestions on the discussion board.
A = 90% of total, B = 80%, C = 70%, D = 60%
(2) Tests: There will be 4 tests of 100 points each, all of which will count toward your final grade. 3 of 4 tests must be taken. All tests will be given at the Testing Center, during a several day period, in accordance with the schedule at the syllabus. Make-up tests will be given only in emergency circumstances and only after the student has already missed one previous test. Make-up tests, if necessary will be given during the last week of the semester (final exam week).
(3) Assignments: There will be 4 graded assignments of 50 points each, of which only the top 3 will be counted toward your final grade. Students must turn-in a minimum of 3 assignments or receive a zero for those assignments short of the 3 minimum. Assignments will be posted several days prior to when they are due; they will be due on the date specified in the syllabus. No late assignments will be accepted and no make-up assignments will be given. Assignments can be passed to me using any one of the 5 following ways:
(a) Hard copy left for me at the PGCC Math Department office prior to 6:00 PM.
(b) Faxed to me at 703-806-5726.
(c) Emailed to me as an attachment.
(d) Copied into digital drop box in blackboard.
(e) Snail-mailed to me; post-marked date will be used for determining timeliness. See staff information for my mailing address.
(4) Project: There will be one project that will require you to not only complete a given assigned problem but post its solution (with detailed explanation) on blackboard for other students to review and from which they can learn. The project will be posted and discussed later in the course. It is worth 50 points.
(5) Final Exam: The final will be 200 points (25% to 29% of your course grade, depending on whether you take 3 or 4 tests). The final must be taken at the Testing Center, during the period specified in the syllabus.
