Concept explainers
i.
To describe the data from the given histogram.
i.
Answer to Problem 30SR
The data is about the roller coasters in the United States which shows the number of coasters on the Horizontal axis and the number of States on the Vertical axis.
Explanation of Solution
Given:
The histogram showing the U.S roller coasters.
Concept Used:
Data from a given frequency table can be represented as a histogram .It is basically a type of bar graph which is used to display the numerical data that is organized at equal intervals. These intervals allow to see the distribution of frequency of data.
Calculation:
Conclusion:
Hence, the data is about the roller coasters in the United States which shows the number of coasters on the Horizontal Axis and the number of States on the Vertical Axis.
ii.
Why jagged line is present on the vertical axis.
ii.
Answer to Problem 30SR
The jagged line also called as broken line is present on the vertical axis to show that the numbers do not start from
Explanation of Solution
Given:
A Histogram
Concept Used:
Concept of jagged line is used.
A line graph is use to show about the change in the value over a given period of time. The line graphs are similar to jagged line that goes across the page. The zig -zag line that appears on the vertical axis shows that the numbers do not start from zero.
Calculation:
Hence, the jagged line also called as broken line is present on the vertical axis to show that the numbers do not start from
