18) You can make a stem-and-leaf plot as frequency table for "The chart below shows the average number of movies seen per person in selected countries. "

0 / . 5
1 / . 2 , . 3 , .3 , . 5

19.) Mr. Green teaches band, choir, and math. This year, he has 57 students that take at least one of his classes. He teaches band to 25 students. There are 9 students who have Mr. Green for math and nothing else. Use the Venn diagram below: How many students take exactly 2 classes with Mr. Green?

Answer: 26 students take exactly 2 classes check the work below.
25 - ( 7 + 3 + 11) Use order of operations or pemdas
25 - ( 21 ) = 4 ** students who take both Band and Choir

Add 11 + 7 + 3 + 4 + 17 + 9 = 51

Subtract 57 - 42 = 15***Students take Math and Choir

Add 15 + 4 + 7 , these are the sections in the Venn Diagram where two circles share the same space.

15 + 4 + 7 = 26 ***** ANSWER

26 students take exactly two classes.
