F. Certain

Step-by-step explanation:

If a student takes most of their time to complete their work, that student will pass the test, and successfully get a passing grade.

Step-by-step explanation:

if it took him that long to do all of those things and do it over and over again i I think that he is fine and also  help and prepared for the test so I think that he would be good so I'm going with the letter f

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.
