It is an acute triangle since all the sides are less than 90 degrees (it's also equilateral)
Standard deviation is the average distance between two points on the graph. If the standard deviation (sd) is high, then the variables relationship is more spread out and unlike one another. The smaller the sd, the closer and less varied the variables are.
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
It would be:
-.72 < -5/8 < -.6 < -7/12
