ACT Aspire Review

ACT Aspire Practice Problems Elaine’s Grocery has a lunch counter where people can order 3 types of sandwiches: egg salad, chicken salad, or falafel. Sandwiches can be made with 2 types of bread: pita or baguette. Create a tree diagram by writing the sandwich choices into the empty boxes to show all the possible combinations for a sandwich from this lunch counter.

Molly built a dollhouse that is a scale model of her home Molly built a dollhouse that is a scale model of her home. The floor plan for the bottom floor of the dollhouse is shown below, with measurements in inches. The rooms and hall are represented by rectangles. Note: 1 inch in the model represents 2.5 feet in the home. Molly added curtains along the entire length of 1 of the shortest walls in the dining room. To determine the length, in inches, of material she needed, she found the value of the expression 3.6(1.05). Molly painted the floors of the 2 rooms and the hall shown in the floor plan. To the nearest 0.01, what is the total area, in square inches, that Molly painted? Write your answer in decimal form to the hundredths place in the box. __________________ square inches

Vocabulary Stem – and – Leaf Plot- The numerical data is listed in ascending or descending order Stems – The greatest place values of the data are used for the stems Leaves- The least place value forms the leaves Back to Back Stem – and – Leaf Plot – Used to compare two sets of data

Example 1 Construct a Stem – and – Leaf Plots The table shows the average weight in pounds of different breeds of adult dogs. Display the data in a stem – and – leaf plot.

Example 2 Construct a Stem – and – Leaf Plots The numbers of minutes Will spent exercising are shown. Display the data in a stem – and – leaf plot.

Example 3 Construct a Stem – and – Leaf Plots The table shows the amounts of peanuts harvested in certain states in a recent year. Display the data in a stem – and – leaf plot.

Example 4 Interpret Data The stem – and – leaf plot shows the number of wins for various softball teams in one season. (a). Find the median and mode. (b). What is the difference between the least and greatest number of wins?

Example 5: Interpret Data The stem – and – leaf plot lists the number of students in each class in a middle school that own pets. (a). Find the median and mode. (b). What is the difference between the least and the greatest number of students who own pets?

Example 6 Back to Back Stem – and – Leaf Plots The monthly snowfall accumulations for 9 months in Syracuse and Buffalo, New York, are shown. (a) In general, which city has the lower amount of monthly snowfall? Explain. (b) Which city has more varied amounts of snowfall? Explain.

Example 7 Back to Back Stem – and – Leaf Plots In general, which city had the higher daily temperatures? Explain. Which city has more varied temperatures? Explain.
