Arecent survey reveals that of the 250 poodle owners interviewed, 93% of them regularly groom their dogs. if there are 50,000 registered poodle owners in the city, how many owners are expected to regularly groom their dogs? a. 46,500 b. 93 c. 3,500 d. 7

there is no question content here, but you for the free points! : d

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.
