MATH 115 QUIZ 1 2022

I have completed this assignment myself, working independently and not consulting anyone except the instructor. INSTRUCTIONS  The quiz is worth 100 points. There are 10 problems.  Each problem is worth 10 points  This quiz is open book and open notes. This means that you may refer to your textbook, notes, and online classroom materials, but you must work independently and may not consult anyone (and confirm this with your submission). You may take as much time as you wish, provided you turn in your quiz no later than this Tuesday.  Show work/explanation. Answers without any work may earn little, if any, credit. You may type or write your work in your copy of the quiz, or if you prefer, create a document containing your work. Scanned work is acceptable also. In your document, be sure to include your name and the assertion of independence of work.  General quiz tips and instructions for submitting work are posted in the Quizzes module.
