Question

the percent composition of a rock sample is as follows: silicates 30% iron sulfite 20% copper compounds 10% iron pyrite 20% carbon compounds 10% calcium carbonates 10% total 100% which type of graph would best display these data? a. line graph b. scatter plot c. pie chart d. 3 - dimensional scatter plot

Explanation:

Pie charts are ideal for showing the proportion of different parts to a whole. Here, we have the percent - composition of a rock sample which represents parts of a whole (100% of the rock). A line graph is used for showing trends over time, a scatter plot for showing the relationship between two variables, and a 3 - dimensional scatter plot for relationships among three variables.

Answer:

C. pie chart
