This is an approximately bell-shaped distribution. The highest bar is in the center, with height = 12. Just to its left and right are bars of heights 6 and 5. At the extremes are bars of heights 2 and 1.
If the highest bar was on the left, it would be skewed left (and if it was on the right, skewed right). A uniform distribution would more or less have the same height level over all the bars.
Idk how many start cards there are o this problem cant be solved...
13.23 is the answer for that equation
These triangles are not congruent. They only have 2 sides and one angle in common, and that is not a congruency theorem.
