Question

what is the range of this set of data?
o a 0 ≤ y ≤ 24
o b 0 ≤ x ≤ 24
o c 30 ≤ y ≤ 80
o d 30 ≤ x ≤ 80

Explanation:

Step1: Identify the variable for range

The range is for the dependent - variable (y - axis). Here, y represents relative humidity.

Step2: Find the maximum and minimum values

From the graph, the maximum value of relative humidity (y) is 80% and the minimum value is 30%.

Answer:

C. $30\leq y\leq80$
