Explanation:

Step1: Locate 30 on x - axis

Find the value 30 on the horizontal axis of the scatter - plot.

Step2: Estimate corresponding y - value

Move vertically from 30 on the x - axis until you reach the trend of the data points. Then move horizontally to the y - axis to estimate the corresponding value. By observing the scatter - plot, as the x - values increase, the y - values seem to follow a linear - like upward trend. The points seem to be roughly increasing in a straight - line fashion. When x = 30, by visual inspection and following the trend of the points, the estimated y - value (height) is around 40.

Answer:

40
