Instructions:

• The quiz is worth 100 points. There are 10 problems, each worth 10 points. Your score on the quiz will be converted to a percentage and posted in your assignment folder with comments.

• This quiz is open book and open notes, and you may take as long as you like on it provided that you submit the quiz no later than the due date posted in our course schedule of the syllabus. You may refer to your textbook, notes, and online classroom materials, but you may not consult anyone.

• You must show all of your work to receive full credit. If a problem does not seem to require work, write a sentence or two to justify your answer.

• Please type your work in your copy of the quiz, or if you prefer, create a document containing your work. Scanned work is also acceptable. Be sure to include your name in the document. Review instructions for submitting your quiz in the Quizzes Module.

Please remember to show ALL of your work on every problem. Read the basic rules for showing work below BEFORE you start working on the quiz.

a) Each step should show the complete expression or equation rather than a piece of it.

b) Each new step should follow logically from the previous step, following rules of algebra.

c) Each new step should be beneath the previous step.

d) The equal sign, =, should only connect equal numbers or expressions.

e) If you do not show work correctly, you will not earn full credit.

At the end of your quiz you must include the following dated statement with your name typed in lieu of a signature. Without this signed statement you will receive a zero.
