There is extra credi t available if you ans wer all 30 questions. Each question is worth 5 points for a total of 140 points , with 10 points extra credit a vailable. You are to work on the projects independently. You can turn in the final project during our class meeting, or submit in the D2L shell as one complete pdf by the due date. You may hand write or type the project . Please show all work for full or p artial credit, using the methods discussed in class. Each question will be graded based on the following rubric. 5 Points A five -point response answers the question correctly.  demonstrates a thorough understanding of the mathematical topics  may contain m inor errors that do not detract from the demonstration of understanding  indicates that the student has completed the task correctly, using mathematically sound procedures, all required work is provided 3-4 Points A three -four -point response is partially c orrect.  demonstrates partial understanding of the mathematical topics and/or procedures embodied in the task  addresses most aspects of the task, using mathematically sound procedures  may contain errors and/or an incorrect solution but provides complete pro cedures, reasoning, and/or explanations, all required work is provided 1-2 Point A one -two -point response is incomplete and exhibits flaws but is not completely incorrect.  demonstrates only a limited understanding of the mathematical topics and/or procedu res embodied in the task  may address some elements of the task correctly but reaches an inadequate solution and/or provides reasoning that is faulty or incomplete  exhibits multiple flaws related to misunderstanding of important aspects of the task, misuse of mathematical procedures, or faulty mathematical reasoning  may contain correct numerical answer(s) but required work is not provided 0 Points A zero -point response is incorrect.  insufficient in demonstrating an understanding of the mathematical topics embodied in the task.  the required work is not provided  may contain answers that are incorrect, irrelevant, incoherent, or are correct but arrived at using an obviously incorrect procedure. FYI: The absolute due date for all homework assignments and p rojects, incl uding the final project, is August 9th, 2022 at 11:59 pm. Any submissions posted after that date and time will not be accepted, and will result in a score of zero. Please make sure you have everything turned in before this da te and time.
