FC: A YEAR IN REVIEW | Math 140 Tammy Bonta
1: SETS | collection of objects called elements or members of the set
2: Variations of the conditional statement Conditional p -> q "if p then q" Converse q -> p "if q then p" Inverse ~p -> ~q "if not p then not q" Contrapositive ~q -> ~p "if not q then not p"
3: Convert 39BA12 to base 10 (3x12^3) + (9x12^3) + (11x12) + (10x1) If a number is shown without a base, we assume the number is in base 10. When converting a base 10 number to a different base, your answer should never contain a digit greater than or equal to that of the different base.
4: Metric Units kilo k 1000 x base unit hecto h 100 x base unit deka da 10 x base unit - - base unit deci d 1/'10 of base unit centi c 1/100 of base unit milli m 1/1000 of base unit
5: SIMPLE INTEREST FORMULA Interest = principal x rate x time i = prt COMPOUND INTEREST FORMULA A = p (1 + r/n)^nt
6: ESTIMATION The process of arriving at an approximate answer to a question. 19 ----20 x $3.99----x $4.00 $80.00 Estimates are not meant to give exact values for answers but are a means of determining whether your answer is reasonable.
7: GUIDELINES FOR PROBLEM SOLVING 1. Understand the problem 2. Devise a plan to solve the problem. 3. Carry out the plan. 4. Check the results.
8: THE NATURE OF PROBABILITY ~an experiment is a controlled operation that yields a set of results ~the possible results of an experiment are called its outcomes. ~an event is a subcollection of the outcomes of an experiment EX-When a die is rolled the event of rolling a number greater than 2 can be satisfied by any one of four outcomes........3, 4, 5, or 6.
9: EMPIRICAL PROBABILITY (relative frequency) P(E) = # of times event has occured total # of times the experiment has been performed EX- In 100 tosses of a fair coin, 44 landed heads up. P(E) = 44/100 = 0.44
10: MY MATH 140 YEAR IN REVIEW I enjoyed this class and learned things that I had lost over my 8 years of being out of high school. Thank you. TAMMY BONTA Math 140 April 30th, 2011
