The ratio of students that take french to spanish is 20: 19. how do the number of students taking french and the number of students taking spanish compare.

More students take French than take Spanish.

Step-by-step explanation:

Effectively, out of every 39 students taking French and/or Spanish, 19 of them take Spanish and 20 of them take French. The number of French students in that group is higher. (20 is more than 19)

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.
