MATH 1553 Midterm: MATH 1553 GT Midterm2 1718F Practice1
Document Summary
Please read all instructions carefully before beginning: each problem is worth 10 points. It is similar in format, length, and dif culty to the real exam. It is not meant as a comprehensive list of study prob- lems. I recommend completing the practice exam in 50 minutes, with- out notes or distractions. The exam is not designed to test material from the previous midterm on its own. However, knowledge of the material prior to section 1. 7 is necessary for everything we do for the rest of the semester, so it is fair game for the exam as it applies to 1. 7 through 2. 9. Circle t if the statement is always true, and circle f otherwise. You do not need to explain your answer: t, t, t, t, t. If a is an n n matrix and its rows are linearly independent, then. Ax = b has a unique solution for every b in rn.
