Answer: The correct options are (1). C, (2). D and (3) A.
Step-by-step explanation: The explanations are given below.
(1) Given that the greatest value of a variable 'n' can be 6, so the value of 'n' will be either equal to or less than 6.
Therefore, we can write
n ≤ 6
Thus, (C) is the correct option.
(2) Since the number line has a closed circle on 9, so a variable n can be equal to 9.
And the number line is shaded to the right of 9, so the value of n can be greater than 9.
Therefore, the value of 'n' can be equal to or greater than 9.
So, we can write
n ≥ 9.
Thus, (D) is the correct option.
(3) Given that z > 34.
So, the value of z can be less than 34 but not equal to 34.
Therefore, the value of z is less than 34.
Thus, (A) is the correct option.
Hence, the correct options are (1). C, (2). D and (3) A.
