According to a poll conducted by the Gallup Corporation in March 2011 , the metropolitan areas with the highest and lowest proportions of obese adults were Evansville, IN-KY, and Boulder, CO, respectively. In Evansville, for every 311
people who were not obese, there were 189
who were. In Boulder, for every 16
obese people, there were 109
who were not obese. At that time, the estimated populations were 358,676
for Evansville and 303,482
for Boulder. How many more obese people were there in Evansville than in Boulder?

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

one set of data has more variation than the other. hope this !

just keep asking questions until you have a better understanding.
