Here are some guidelines on what to study for the first exam. If I think
of something else, this might change. This version was posted on Tuesday
night, if you want to check if you have the current guidelines.
NOT ON THE TEST:
* Odds (all of 15.7)
* Logistic Growth Model (all of 10.4)
* Sum of a Geometric Sequence.
THESE FORMULAS WILL BE GIVEN TO YOU:
* Permutations of size k from n objects
* Combinations of size k from n objects
* Compound Interest formula on p359
* Formula for Sum of an Arithmetic Sequence on p353
GENERAL FORM OF THE EXAM:
There will be a matching section and a few true/false questions. There is
also a section of "short answer" questions which should take less time
than the other questions on the test. Then there are specific questions
about the different topics we've covered -- counting, probabilities,
population growth models, etc.
Most of the questions will be very similar to examples done in class or
problems on the homework. The matching section deals with terms that
we've learned. The true/false and short answer questions are quick
problems based on examples. Some of them test your understanding of the
concepts we've learned about. Here's an example of a "conceptual"
question like this:
"True/False: In the logistic growth model, the population can
cycle up and down forever"
This is true, incidentally, but you don't need to know the logistic model
for the test. (See above)
You may have noticed that this week's homework has problems from both
chapters 10 and 15, so it's already a review for you. Unfortunately you
won't get that homework assignment back until next week. Here's a list of
problems I've chosen which I think could be very helpful. They're all
odd-numbered problems from the book, so you can check your answers in the
back:
Chapter 15: 5, 7, 19, 21, 23, 35, 49 (and 41), 51 (and 43), 55, 71
Chapter 10: 1, 3, 17, 19, 23, 25, 29
[In 23, add (c): is your answer to (b) more or less than the annual
interest rate?]
If you _understand_ these problems, I think you'll do well on the exam.
Be careful: "understanding" is different than "I can do the problems if I
have my book in front of me and compare them to examples."
"Understanding" means you know and understand the concepts you're using,
and you could solve these (or similar) problems without your book, notes,
or help from a friend.
Good luck and happy studying!
