ma253 , Spring 2007 – Midterm 1 This test has two parts. The first part is focused on concepts. It consists of ten true-false questions very much like the review problems in our textbook. This part is worth up to 40 points. The second part consists of three problems, worth 20 points each, and a bonus problem worth up to 15 points. This part is worth up to 60 points without the bonus problem, and up to 75 points if we include the bonus problem. The test will be graded out of 100 points. The bonus problem is tricky, so don’t spend time on the bonus problem until you’re satisfied with your work on the other problems. As you work on the test, you may use your calculator, and you may also use one 8.5 × 11 sheet of notes. (But consulting notes takes time — watch the clock!) Remember to write up your answers, that is, to explain your reasoning and your computations in good prose. Correct answers without correct explanations will not get full credit.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
