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
I think its Spain though I'm not sure
What is Spain?
To create a frequency table using equal intervals for the average number of movies per person, you need to group the data into intervals and count the number of countries falling within each interval.
First, you have to determine the range of the data, which is the difference between the highest and lowest values. In this case, the lowest value is 0.5 (Turkey), and the highest value is 4.5 (US), so the range is 4.5 - 0.5 = 4.
Next, decide on the number of intervals you want to use. For simplicity, let's say we will use 5 intervals.
To find the width of each interval, divide the range by the number of intervals. In this case, the width would be 4 / 5 = 0.8.
Now, create the intervals and count the number of countries falling within each interval:
Interval 1: 0.5 - 1.3 (Turkey, Japan, UK, Finland)
Interval 2: 1.3 - 2.1 (Austria, Germany, Spain, Sweden, Denmark)
Interval 3: 2.1 - 2.9 (Switzerland, France, Norway, Canada)
Interval 4: 2.9 - 3.7 (US)
Based on this frequency table, we can see that the interval with the highest frequency is Interval 2, which includes Spain. Therefore, Spain has the highest average number of movies per person among the listed countries.
Please note that this method assumes all countries are included in the given data, and it might not represent the overall average number of movies per person across all countries globally.
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. "

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.
