18) N is between Zero and 50

The Squares we are looking at are 28 more than N

and 100 more than N

Thus, these squares differ by 72

and they are between 28 and 150

The list of Squares to look at are:
36, 49, 64, 81, 100, 121, 144
The pair that differ by 72 are 49 and 121,

so N is 21.

19) Try a VENN DIAGRAM

with the HONOR ROLL circle

overlapping the SPORTS circle.

120 in the over lap
300 in the sports
P(in Honor Roll given in Sports)

=  120/300 = 2/5
