questions asked will be similar to this exam. You can have access to the book and
lecture notes and a calculator.

QUIZZES. BRING YOUR ID TO THE EXAM.
This is an open book and open note exam and you may use a calculator. You may NOT
use copies of the online quizzes. There are 9 multiplechoice questions and three open
ended questions. In the case of multiplechoice questions, choose one answer only
. In the
case of openended questions be specific, write clearly, and do not repeat yourself.
