1. A company was studying the demographics of their customers. As part of the study, they collected the following variables: mar
ital status, credit rating (low, medium, high), annual income, and age. Label each variable as qualitative or quantitative, discrete or continuous, and nominal, ordinal, or interval/ratio.
Total miles traveled in p hours = p*q miles and Total miles traveled in r hours = r*s miles so, average rate of speed = total miles traveled / number of hours =[{(p*q)+(r*s)} / (p+r)] miles per hour
Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon
