Q. Which is the set of integers greater than or equal to 22 and less than 66?\newlineChoices:\newline(A) {2,6}\{2, 6\}\newline(B) {2,3,4,5}\{2, 3, 4, 5\}\newline(C) {3,4,5,6}\{3, 4, 5, 6\}\newline(D) {3,4,5}\{3, 4, 5\}
  1. Identify Inequality Signs: Let's first identify the inequality signs for the set of integers we are looking for. We need to find the set of integers that are greater than or equal to 22 and also less than 66.\newlineInequality signs: \geq for greater than or equal to, and < for less than.
  2. Translate to Set Notation: Now, let's translate the inequality into set notation. The set notation for integers greater than or equal to 22 and less than 66 is \{x \,|\, 2 \leq x < 6\}.
  3. List Integers: Next, we need to list out the integers that satisfy the inequality 2 \leq x < 6. These integers are 22, 33, 44, and 55.
  4. Match with Choices: Finally, let's match our set of integers {2,3,4,5}\{2, 3, 4, 5\} with the given choices to find the correct answer.\newline(A) {2,6}\{2, 6\} does not include all the integers between 22 and 66 and includes 66 which should not be included.\newline(B) {2,3,4,5}\{2, 3, 4, 5\} includes all the integers between 22 and 66, excluding 66, which is correct.\newline(C) {3,4,5,6}\{3, 4, 5, 6\} does not include 22 and includes 66 which should not be included.\newline(D) {2,6}\{2, 6\}22 does not include 22 which should be included.
