Final answer:
Mahagony's purchase of 9 single-serving containers of ice cream would be represented as a discrete data set because you count the number of items, which does not allow for fractional or decimal values. This is an example of quantitative discrete data.
Step-by-step explanation:
The question addresses whether the solutions to Mahagony's purchase of ice cream are discrete or continuous. A discrete data set is one where the values can only be specific, separate (often integer) amounts, such as the number of ice cream containers purchased. In contrast, continuous data sets allow for any value within a range, including fractions and decimals, such as the weight of ice cream in a container. Given that Mahagony bought 9 single-serving containers, which are specific items that can be counted, the solutions to her grocery shopping graph would be discrete.
An example of a quantitative discrete data set could be the three cans of soup, two packages of nuts, four kinds of vegetables, and two desserts mentioned in example 1.7 because these are all items that you count. The numbers of "That's My Jam" and "Cherry Garcia" ice cream containers are also counted, and thus, represent a quantitative discrete dataset.
