Listed below are the various projects that will be required throughout the semester. Each of these
are worth 25 points and will be due the day following the exam for the appropriate chapter.
These projects take you above and beyond the material covered in the book or require outside
data acquisition. You may work in groups of up to three people per project. Turn in one project
with all group member's names on it. Plan on reading the section of the book dealing with the
matter before we cover it in class; you will not always have time to finish the project if you wait
until we do. Give me the results of any surveys along with the projects.
Project 1, Chapter 4
Identify a car or other object of more than $5000 which you would like to purchase. This can
come from a television, radio, or newspaper ad, or a dealer. Contact your bank or credit union to
find the current interest rates. In your project, identify the object you wish to purchase and the
list price. Then, compute and give the monthly payments, total payment, and amount of interest
on the object for 36, 48, and 60 months loan. Use the interest rate given by your lending
institution and also 2.9% and 12.9%. Note there will be nine groups here (3 different months by 3
Use the matrices A,B,C,O,D and I given on the handout to verify the properties below.
- Commutativity of addition
- Associativity of addition
- Identity for addition
- Associativity of multiplication
- Identity for multiplication
- Left distributive
- Right distributive
- Transpose of the transpose
- Transpose of a sum
- Transpose of a product
- Determinant of product
- Determinant of transpose
- Inverse of a product
- Examine Det D and explain why D has no inverse. Then, row-reduce the augmented
matrix and explain what happens when a matrix has no inverse.
Create a fair game for two or more players with at least four distinct outcomes (this is easier with
die/dice or a spinner). Create a payoff table (probability distribution).
Pick a subject (mathematics, english, biology, etc). Ask at least 25 students "Did you have a
'math' class last semester?" and "Do you have a 'math' class this semester?". Using this semester's
probabilities as a starting point, write the initial-state matrix and transition matrix. Find the next
three state matrices and the steady-state matrix. Use the current state as the initial-state matrix.
