Step-by-step explanation:

B. At 36%, the percentage of girls who like red is higher

Step-by-step explanation:

There are 15 boys overall.

5 of those boys liked green.

Divide 5 by 15

0.33333. . . or 33% of boys like green

There are 11 girls overall.

Therefore the answer is A

Hope this helped :)

answer: 1 and 3

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.
