CHEGG A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study follow. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker. Click on the datafile logo to reference the data. Enter negative values as negative, if necessary. Use the best subset regression procedure to predict risk of stroke. Which independent variable provides the best regression model if only one independent variable is in the model? Age Which independent variables provide the best regression model if two independent variables are in the model? Age and Smoker Using the best regression procedure, how many independent variables are in the highest adjusted R 2 model? What is the value of R 2(adj)? Note: report R 2(adj) as a percentage (to 1 decimal). % Show the best regression model below (to 3 decimals, if necessary). Enter 0 if the independent variable listed below is not in your best regression model. Rating = + Age + Pressure + Smoker

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
