Q. Which is the set of numbers greater than 11 and less than or equal to 1111?\newlineChoices:\newline(A){xx>1 and x11}\{x | x > 1 \text{ and } x \leq 11\} \newline(B){xx<1 and x11}\{x | x < 1 \text{ and } x \geq 11\} \newline(C){xx>1 or x11}\{x | x > 1 \text{ or } x \leq 11\} \newline(D){xx<1 or x11}\{x | x < 1 \text{ or } x \geq 11\}
  1. Identify Inequality Signs: Identify the inequality signs for the conditions given in the question prompt.\newlineWe need to find the set of numbers that are greater than 11 and at the same time less than or equal to 1111.\newlineThe inequality sign for "greater than 11" is >.\newlineThe inequality sign for "less than or equal to 1111" is \leq.
  2. Combine Inequalities: Combine the inequalities to form a compound inequality that represents the conditions given in the question prompt.\newlineThe compound inequality that combines both conditions is: 1 < x \leq 11.
  3. Translate to Set Notation: Translate the compound inequality into set notation.\newlineThe set notation that represents the numbers greater than 11 and less than or equal to 1111 is: \{x \mid x > 1 \text{ and } x \leq 11\}.
  4. Match with Choices: Match the set notation from Step 33 with the given choices.\newlineThe correct choice that matches our set notation is:\newline(A)\{x | x > 1 \text{ and } x \leq 11\}.
