Solve by using a graph. 1. A carpet cleaner charges $25 per room cleaned. Predict the cost of having 5 rooms cleaned. 2. The table shows the number of packages contained in trucks. Make a graph of the data and use it to predict the number of packages that can be transported in 5 trucks. 3. Use the graph that shows bagel prices. What is the price of 2 dozen bagels? Course 2, Lesson 10-4 ANSWERS 1. $125 3. $20 Course 2, Lesson 10-4 2. 1,400 Statistics and Probability HOW do you know which type of graph to use when displaying data? Course 2, Lesson 10-4 Statistics and Probability • 7.SP.4 Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. Mathematical Practices 1 Make sense of problems and persevere in solving them. 3 Construct viable arguments and critique the reasoning of others. 4 Model with mathematics. 6 Attend to precision.
