In last year's ruby season, player A scores 85 time from 150 kicks. player B scores 152 times from 200 kicks, and player C scores 112 times from 160 kicks. a. what is each players success rate:
i. as a ratio (in the form A:B:C)?

hint:work out each players success rate as a fraction (scores/kicks), put these over a common denominator, and then compare the numerators directly

ii. as a percentage?

b. put the players in order of success rates, highest first.​

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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.
