Maths Algebra Precalculus (2nd Edition) Exercise 1
Step 1 1 of 7 We need to use set notation to write the elements of �J, which is “the set of whole number multiples of 33 that are less than 1515” then determine if the statement, 15∈�15∈J is true or false. How do we write a set using set notation? Step 2 2 of 7 A set notation lists the elements of the set using braces (or curly brackets), {{ }}. Step 3 3 of 7 In this case, we know that set �J is the the set of whole number multiples of 33 that are less than 1515. By recalling that whole numbers include 00 and the natural (counting) numbers, we write the set notation as �={0,3,6,9,12}.J={0,3,6,9,12}. Note that 00 is a multiple of every whole number. What does the statement, 15∈�15∈J, means?
