A point is graphed in the coordinate plane with the origin labeled “O”. The horizontal axis is labeled “age in months” and the numbers 0 through 84, in increments of 12, are indicated. The vertical axis is labeled “weight in kilograms” and the numbers 0 through 100, in increments of 25, are indicated. The point 36 comma 82 is indicated.
 
 
What does the point on the graph tell you about the panda?

After a board game competition, the tournament director collects 50 dice from the games played and rolls each one until he gets bored and tries a different one. The scatter plot shows the number of times he rolled each die and the number of 6s that resulted during those rolls.

Select a point in the scatter plot and give its approximate coordinates, then tell the story of that point in the context of the problem.
