Identify the following tables as linear, nonlinear, directly proportional, or inversely proportional. Number of Spiders 1234 Number of Legs Side Length (cm) 1234 Volume (cm 3 ) Pineapple Juice (c) 124 Grape Juice (c) 842 Making punch: The relationship between the volume of a cube and its side length:

EXIT RAMP Identify this relationship: y = kx or k = y/x EXIT ONLY EXIT 12E

Make a function table and graph the function: y = - 2x + 4. What is the above “form” called? Therefore, is it linear or nonlinear? Is it directly proportional? Inversely? Have Practice Test ready. Check answers from side board. Ask the tough questions!

Motor Math (3-8-3 [4 tomorrow]) Thursday February 16, 2010 Probability & Simple Events SPI 2.6 Express the ratio between two quantities as a percent, and a percent as a ratio or fraction. SPI 2.7 Use ratios and proportions to solve problems. SPI 5.4 Use theoretical probability to make predictions. 1.Define: probability (Use words/formula on page 429.), geometric probability (Use words/formula on page 434.) 2.If you had a bag of letters made up of “Umpty Squat,” what would be the probability that you would reach in and get a “t?” 3.If you had a spinner numbered 1-8, what would be the “chance” you would get a “3” or a “5?”

EXIT RAMP You roll one di. What is the probability you will roll a “6?” p(rolling 6) EXIT ONLY EXIT 12E

Motor Math (3-8-4) Friday February 17, 2010 Sample Spaces SPI 5.4 Use theoretical probability to make predictions. 1.In your drawer, you have 3 black pairs of socks, 4 blue pairs of socks, and 2 polka dotted socks. What is the probability of you blindly grabbing a pair of blue socks? 2.Define: sample space, tree diagram, odds in favor 3.At Dairy Queen they sell vanilla and chocolate soft swirl ice cream. You can get it in a waffle or sugar cone. What are all the possible combinations you can get?
