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

does anyone know the answer??

To create a frequency table with equal intervals for the average number of movies per person, we can group the data into intervals and count the number of values falling within each interval.

Here's how you can create the frequency table step-by-step:

1. Determine the range of the data. The range is the difference between the highest and lowest values. In this case, the lowest value is 0.5, and the highest value is 4.5. So, the range is 4.5 - 0.5 = 4.

2. Determine the number of intervals you want. For this example, let's use 5 intervals.

3. Calculate the interval width by dividing the range by the number of intervals. In this case, the interval width is 4 / 5 = 0.8.

4. Determine the starting point for the first interval. It is usually the lowest value rounded down to the nearest multiple of the interval width. Here, the starting point will be 0.5 rounded down to 0.

5. Create the intervals. Add the interval width to the starting point successively to generate the intervals. Based on the interval width and starting point, the intervals can be defined as follows:

Interval 1: 0.0 - 0.8
Interval 2: 0.8 - 1.6
Interval 3: 1.6 - 2.4
Interval 4: 2.4 - 3.2
Interval 5: 3.2 - 4.0

6. Count the frequency of each value falling within each interval. Here is the frequency table based on the given data:

Interval Frequency
0.0 - 0.8 1
0.8 - 1.6 2
1.6 - 2.4 3
2.4 - 3.2 3
3.2 - 4.0 2

Note: Please keep in mind that tally marks were not required for this particular frequency table.

To create a frequency table using equal intervals for the average number of movies per person, follow these steps:

1. Determine the range of the data. The range is the difference between the highest and lowest values in the data set. In this case, the lowest average number of movies per person is 0.5 (Turkey) and the highest is 4.5 (US). So the range is 4.5 - 0.5 = 4.

2. Decide on the desired number of intervals. Since we are using equal intervals, it's important to choose a suitable number of intervals that will effectively represent the data. In this example, let's choose 5 intervals.

3. Calculate the size of each interval. Divide the range by the number of intervals to determine the size of each interval. In this case, 4 / 5 = 0.8. So each interval will have a size of 0.8.

4. Establish the intervals by starting from the lowest value and adding the interval size consecutively. The intervals for this example will be as follows:

0.5 - 1.3
1.3 - 2.1
2.1 - 2.9
2.9 - 3.7
3.7 - 4.5

5. Count the frequency of each interval by examining the data set and identifying how many values fall into each interval. For example, counting the frequencies using the given data, we have:

0.5 - 1.3: 2 (Turkey, Japan)
1.3 - 2.1: 2 (UK, Finland)
2.1 - 2.9: 3 (Spain, Sweden, Denmark)
2.9 - 3.7: 0
3.7 - 4.5: 2 (Norway, Canada)

6. Record the frequencies in a table format. This is the final frequency table:

Interval | Frequency
------------------------------
0.5 - 1.3 | 2
1.3 - 2.1 | 2
2.1 - 2.9 | 3
2.9 - 3.7 | 0
3.7 - 4.5 | 2

Note: Tally marks are typically used in a frequency table, but in this case, they are not required.

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.
