To find the mean or equal share value, we need to calculate the average of the values given in each graph.
In the first graph, the values are 10 and 10. Their average is (10 + 10)/2 = 20/2 = 10.
In the second graph, the values are 2 and 2. Their average is (2 + 2)/2 = 4/2 = 2.
In the third graph, the values are 30 and 30. Their average is (30 + 30)/2 = 60/2 = 30.
Therefore, the equal share value or the mean for each graph is:
1st graph: 10
2nd graph: 2
3rd graph: 30
