Use equal intervals to make a frequency table for the average number of movies per person. You do not need to show tally marks.
Country Average Number of Movies
Turkey 0.5
Japan 1.2
UK 1.3
Finland 1.3
Austria 1.5
Germany 1.8
Spain 2.2
Sweden 2.2
Denmark 2.2
Switzerland 2.5
France 2.5
Norway 3.0
Canada 3.0
US 4.5
0-0.7 | 1
0.8-1.5 | 4
1.6-2.3 | 4
2.4-3.1 | 4
3.2-3.9 | 0
4-4.7 | 1
To create a frequency table using equal intervals for the average number of movies per person, you first need to determine the range of the data. In this case, the lowest average number of movies is 0.5 and the highest is 4.5, giving us a range of 4.
Next, you need to decide on the width of the intervals. Equal intervals means dividing the range into equal parts. You can choose any width that makes sense for the data. In this case, let's choose an interval width of 1.
Using the given data, we can create the following frequency table:
Interval Frequency
0.5-1.4 5 (Turkey, Japan, UK, Finland, Austria)
1.5-2.4 4 (Germany, Spain, Sweden, Denmark)
2.5-3.4 2 (Switzerland, France)
3.5-4.4 2 (Norway, Canada)
4.5-5.4 1 (US)
To determine the frequency for each interval, count the number of countries with an average number of movies falling within that interval range. For example, in the interval 0.5-1.4, there are 5 countries: Turkey, Japan, UK, Finland, and Austria.
Remember that the frequency table does not need to show tally marks, so you can simply list the intervals and their corresponding frequencies as shown above.

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.
