Final answer:
The correct graph for representing the relationship between the number of pages and the price of books in a scatterplot has 'pages' on the x-axis and 'price (dollars)' on the y-axis.
Step-by-step explanation:
The question is seeking the correct way to represent bivariate data on a scatterplot where the variables are the number of pages and the price of books. In a scatterplot, the independent variable is usually plotted on the x-axis, and the dependent variable is plotted on the y-axis.
Since the number of pages likely influences the price of the book, the number of pages is the independent variable, and the price (in dollars) is the dependent variable. Therefore, the appropriate graph will have pages on the x-axis and price (dollars) on the y-axis.
A scatterplot represents bivariate data by plotting the independent variable on the x-axis and the dependent variable on the y-axis.
In this case, the book store is keeping track of the price of books according to the number of pages. Therefore, the scatterplot that represents this bivariate data would have pages on the x-axis and price (dollars) on the y-axis.
