Unformatted text preview: MthSc 207 – Fall 2007 Sections 6.1 – 6.5 Test 1 – Version A 1 General Directions: • Show work where possible. Answers without supporting work (where work is appropriate) may receive little credit. • Do not round intermediate calculations. • Answers in context ALWAYS require units. • Round your answers to 3 decimal places UNLESS the answer needs to be rounded differently to make sense in the context of the problem OR the directions specify another type rounding OR the complete answer has less than 3 decimal places. • When you are asked to write a model, include all components of a model: an equation, a description of the input and units, a description of the output and units, and the input interval when known. • When asked to write a sentence of practical interpretation, answer the questions: when?, what?, how? and how much? using ordinary, conversational language. Do not use math words, terms, or unnecessary phrases. • Always use a ruler when estimating values off of a graph. Statement of Academic Integrity: I have not and will not give or receive improper aid on this test.
