  1. MAT 1033A Test 4 Review and Practice Solutions

  2. Calculators and calculating devices are strictly prohibited. • Tests may not be made up for any reason other than a mandatory school – sponsored activity for which you must miss class. • If you miss one test for any other reason, your final exam score will be substituted for that test. A second missed test is a zero. No homework bonuses are awarded on a test when the final exam is substituted or you receive a zero on a missed test.

  3. Be sure to complete at least 80% of your pie for Objective 4 to receive the 10 point bonus. Your percentage must be at least 80.0% to receive the bonus.
