Concept explainers
To identify: The variable according to the set of numbers the best describes its values: the year y ; the median selling price p for a house that year.
Given information:
The given statement says that the year y ; the median selling price p for a house that year.
Explanation:
Consider the given situation:
The year y includes all positive values therefore y should be natural numbers. As it is known that natural numbers includes all positive integers.
The selling price p for a house for the year may not be same for each year, though this selling price is not necessarily a natural number and occasionally might even be a fraction.
The selling price p should be a rational number because all numbers that can be written as a quotient of integers
