A. Each sector of a circle graph shows a category and the relative size of the category .
B. A circle graph can only be used for categories where the data adds up to 360.
C. Each sector of a circle graph that is the same size must be the same color .
D. The percents in each circle graph add up to 360 .
The answer is "No", the cost of water is not proportional to the number of sold.
The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.
As per the given information in the question,
The cost of 6 bottles of water is $4.
Then, the price of each bottle will be,
= $4/6 = $0.66
The next condition is,
The cost of 18 bottles of water is $10
Then, the price of each bottle will be,
= $10/18 = $0.55
Comparing both the values, the ratio is not the same.
