  • 2. 

    If x is = 20, then x2 is 100.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. If x is equal to 20, then x^2 (x squared) would be equal to 400, not 100. Therefore, the correct answer is False.

    Rate this question:

  • 3. 

    If y is = -5, then y2 is 25.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    If y is equal to -5, then y^2 (y squared) would be equal to 25. This is because when you square a negative number, the result is always positive. Therefore, the statement "If y is = -5, then y^2 is 25" is true.

    1 on the number line above has the lowest absolute value. - ProProfs

    1 on the number line above has the lowest absolute value.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the number 1 on the number line does not have the lowest absolute value. The absolute value of a number represents its distance from zero on the number line. Since 1 is further away from zero than any negative number, it does not have the lowest absolute value.

    Rate this question:

  • 5. 
    If the figure provided is drawn to scale, which of the following points on the number line above has the greatest absolute value? - ProProfs

    If the figure provided is drawn to scale, which of the following points on the number line above has the greatest absolute value?

    • Point A.

    • Point B.

    • Point C.

    • Point D.

    • Point E.

    Correct Answer
    A. Point A.
    Explanation
    The figure provided is not visible, so it is not possible to determine the positions of the points on the number line. Therefore, an explanation cannot be provided.

    Rate this question:

  • 6. 

    What is the value of |k|?     (1)    k3 = 27     (2)    k = |k|

    • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

    • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

    • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

    • EACH statement ALONE is sufficient.

    • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

    Correct Answer
    A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
    Explanation
    Statement (1) states that k^3 = 27. From this, we can determine that k = 3, as 3^3 = 27. Therefore, we can determine the value of |k| to be 3.

    Statement (2) alone does not provide any information about the value of k or |k|. Therefore, it is not sufficient to answer the question.

    Thus, statement (1) alone is sufficient to determine the value of |k|, while statement (2) alone is not sufficient.

    What is the value of |y|?     (1)    y = -3     (2)    y2 =  - ProProfs

    What is the value of |y|?     (1)    y = -3     (2)    y2 = 

    • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

    • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

    • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

    • EACH statement ALONE is sufficient.

    • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

    Correct Answer
    A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
    Explanation
    Statement (1) provides the value of y as -3. The absolute value of -3 is 3, so the value of |y| is 3.

    Statement (2) does not provide any information about the value of y, so it is not sufficient to determine the value of |y|.

    Therefore, statement (1) alone is sufficient to answer the question, but statement (2) alone is not sufficient.

    Rate this question:

  • 8. 

    Is x a positive integer?     (1) |x| >1     (2) 1

    • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

    • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

    • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

    • EACH statement ALONE is sufficient.

    • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

    Correct Answer
    A. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
    Explanation
    Statement (2) alone is sufficient because it states that x is greater than 1, implying that x is a positive integer. However, statement (1) alone does not provide enough information to determine if x is positive or negative, as it only states that the absolute value of x is greater than 1, which could include negative values as well. Therefore, statement (2) alone is sufficient to answer the question, but statement (1) alone is not.

    Rate this question:

  • 9. 

    Is y greater than x?     (1) |y|<1 and |x| <2     (2) y>0 and x is not 0

    • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

    • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

    • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

    • EACH statement ALONE is sufficient.

    • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

    Correct Answer
    A. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
  • 10. 

    Given that n is an integer, is ┃n┃× n < 2n?     (1) n < 0.     (2) n = –6

    • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

    • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

    • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

    • EACH statement ALONE is sufficient.

    • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

    Correct Answer
    A. EACH statement ALONE is sufficient.
    Explanation
    The absolute value of n multiplied by n will always be less than 2n if n is negative. Therefore, statement (1) alone is sufficient to answer the question. Statement (2) alone is also sufficient because it provides a specific value for n (-6) which is negative, satisfying the condition. Therefore, each statement alone is sufficient to answer the question.
