Math Problem Statement
Solution
The image contains a set of questions requiring the roster method to represent sets. Here are the questions listed for clarity:
- Use the roster method to represent each set:
- a. The set of natural numbers less than 5.
- b. The solution set of .
- c. The set of negative integers greater than .
- d. The set of months of the year with a name that starts with the letter J.
- e. The set of whole numbers less than 8.
- f. The set of natural numbers that satisfy .
- g. The set of counting numbers larger than and less than or equal to 6.
Let me now provide the solutions for each:
a. The set of natural numbers less than 5.
- Natural numbers are positive integers starting from 1.
- Roster form:
b. The solution set of .
- Solve for : .
- Roster form:
c. The set of negative integers greater than .
- Negative integers greater than are .
- Roster form:
d. The set of months of the year with a name that starts with the letter J.
- The months are January, June, July.
- Roster form:
e. The set of whole numbers less than 8.
- Whole numbers are non-negative integers.
- Roster form:
f. The set of natural numbers that satisfy .
- Solve which gives .
- Since is a natural number, .
- Roster form:
g. The set of counting numbers larger than and less than or equal to 6.
- Counting numbers (natural numbers starting from 1).
- Roster form:
Would you like further clarification on any of the answers?
Here are 5 related questions to expand your understanding:
- What is the difference between natural numbers and whole numbers?
- Can sets have an infinite number of elements? Give an example.
- How would you represent an empty set in roster notation?
- How would you express a set of even numbers less than 10 using the roster method?
- What is the difference between set-builder notation and roster notation?
Tip: Roster method lists all the elements of a set explicitly, but it's more efficient to use set-builder notation for larger or infinite sets.
