Yes
Y varies directly with x, it is a direct relationship between the two.
Answer:
The answer is the third one.
Step-by-step explanation:
72 and 99 are values in this set because they are the lower and upper extremes, respectively.
The midrange is the average of the highest value and the lowest value (the extremes). 72 + 99 = 171. 171 / 2 = 85.5
The median is 81, because that is where the line in the middle is at.
Each part of the plot equals 25%. Since the lower two quartiles equal 50%, and so do the upper two quartiles, they're the same. This is the answer.
