### Educational Transcript

#### Text Questions

1. **Questions on Reading Habits:**
   - How many people read more than 5 books?
   - What would you estimate for the average number of books read by a person in this club?

2. **Percentage and Data Representation:**
   13. 
   a. A 5 cm long rectangle serves as a percentage bar chart. What percentage of the data does one 1.5-cm section represent?
   b. In the percentage bar chart in part (a), 20% of data can be represented by how long a section?

3. **Circle Graph Questions:**
   14. Use the circle graph to answer the following questions:  
   a. Which is the largest continent?  
   b. Which continent is about twice the size of Antarctica?

#### Pie Chart Explanation

**Title: Earth's Land**

The chart displays the proportion of Earth's land divided among continents. The segments and their respective percentages are as follows:

- **Asia**: 30%
- **Africa**: 20%
- **North America**: 16%
- **South America**: 12%
- **Antarctica**: 9.5%
- **Europe**: 7%
- **Australia**: 5%
- **Other**: 0.5%

This pie chart visually represents the land area distribution of the continents. Asia is shown as the largest segment with 30%, while "Other" is the smallest with 0.5%. The chart helps in understanding the relative sizes of continents on Earth.

Expert Solution
Step 1

The question is about graphical representation of data

Given :

From graph :

Continent "As" = 30 %

Continent "Af" = 20 %

Continent "NA " = 16 %

Continent "SA" = 12 %

Continent "E" = 7 %

Continent " An " = 9.5 %

Continent " Au " = 5 %

Other = 0.5 %

 

To find :

1 ) what continent is about twice the size of "An"? 

2 ) which two continents make up about half of earths land area ?

3 ) What is the ratio of the size of "Au" to "NA"?
