Make a histogram, using a bin width of ten, to display the bowling scores for these 23 players: 118, 102, 82, 78, 95, 84, 104, 74, 115, 98, 85, 99, 79, 103, 76, 93, 83, 96, 81, 92, 89, 97, 91.

n

step-by-step explanation:

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.
