Question

An environmental scientist performs research to discover what is in the solid garbage of the average American family. She calculates these amounts in kilograms per year. The categones are paper, yard waste, metals, glass, plastics, food scraps, and "other." Which kind of graph should she use to present her finding, and how should the graph be labeled?
O A. She should use a line graph. The x-axis should be labeled "kind of garbage." The y-axis should be labeled "kilograms per year."

O B. She should use a circle graph. Each segment of the graph should be labeled "number of kilograms per year."

O C. She should use a bar graph. The bottom of each bar should be labeled "kilograms per year." The vertical side should be labeled "type of garbage."

OD. She should use a bar graph. The bottom of each bar should be labeled with the category of garbage. The vertical side should have a scale and be labeled "kilograms per year."​

Answer 1

Answer:

D). She should use a bar graph. The bottom of each bar should be labeled with the category of garbage. The vertical side should have a scale and be labeled "kilograms per year."​

Explanation:

Bar graphs are characterized as the graphic tool which are primarily employed to establish comparison between various groups or to observe the changes occurred over time.

As per the question, the environmental scientist must opt for the 'bar graph' as it will assist her in displaying the data of various categories(paper, yard waste, metals, etc.) through bars on the x-axis while the vertical side or y-axis would show 'kilograms per year' which will display the differences in their amounts. Thus, option D is the correct answer.
