Answer:
The set of numbers that best describes the height of an airplane as it descends to an airport runway is Rational number, Real number.
The set of numbers that best describes the The score with respect to par of several golfers: 2, -3, 5, 0, -1 is Integer, Rational number, Real number.
Step-by-step explanation:
Consider the provided information.
Natural numbers: The natural numbers are 1, 2, 3, 4, 5,…
Whole number: Whole numbers are the set of natural numbers but starts with 0. i.e. 0, 1, 2, 3, 4, 5,…
Integers: Integers are the set of whole number and the negatives of the natural numbers, i.e, … ,-2, -1, 0, 1, 2, …
Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.The decimal expansion of rational numbers may terminate or become periodic.
Irrational number: A number is irrational if it cannot be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.
Real numbers: All rational and Irrational numbers are called real number.
Part(A)
The height of an airplane as it descends to an airport runway.
The height of an airplane descends to airport can be thousands of feet or it can be half feet.
Therefore, the height of airplane can be a rational number or real number.
Part (B) The score with respect to par of several golfers: 2, -3, 5, 0, -1
The score of the golfers are negative as well as positive.
Therefore, the set of number which represents the score of several golfers is: Integer, rational and real number.
