Which is the set of numbers less than or equal to6 or greater than or equal to 12?Choices:(A)\{x | x < 6 \text{ or } x > 12\} (B)\{x | x < 6 \text{ and } x > 12\} (C){x∣x≤6 and x≥12}(D){x∣x≤6 or x≥12}
Q. Which is the set of numbers less than or equal to 6 or greater than or equal to 12?Choices:(A){x∣x<6 or x>12}(B){x∣x<6 and x>12}(C){x∣x≤6 and x≥12}(D){x∣x≤6 or x≥12}
Understand the problem: Understand the problem.We need to find the set of numbers that are either less than or equal to 6 or greater than or equal to 12. This means we are looking for two separate ranges of numbers.
Identify inequality signs: Identify the correct inequality signs.For numbers less than or equal to 6, we use the inequality sign ≤. For numbers greater than or equal to 12, we use the inequality sign ≥.
Determine logical connector: Determine the logical connector.The problem asks for numbers that are either in one range or the other, which means we are looking for a union of two sets. The correct logical connector for a union is “or”.
Translate into set notation: Translate the problem into set notation.Using the inequality signs and the logical connector identified in the previous steps, we can write the set notation as x∣x≤6 or x≥12.
Match with choices: Match the set notation to the given choices.The correct set notation x∣x≤6 or x≥12 matches choice (D).
