What does the abscissa of the point of intersection of the less than type and of the more than type cumulative frequency curves of a grouped data represent?
The abscissa of the point of intersection of the less than type and of the more than type cumulative frequency curves of a grouped data gives its median.
Solution:
Let the length of the shorter side be x metres.
Thus the length of the longer side=(x+30) m
Length of the diagonal=(x+60)m
Each angle of a rectangle=90 degrees
By Pythagoras Theorem, (diagonal)2=(shorter side)2+(longer side)2
(x+60)2 ...
