At a school 40% of the sixth grade students said that hip hop is their favorite kind of music, how many sixth grade students are at school?

The answer is 2.5 times The no of students who said that hip hop is their favorite kind of music

Step-by-step explanation:

   Let the total no of sixth grade students be n

   At a school 40% of the sixth grade students said that hip hop is their  

   favorite kind of music

   Let the number of students who like the hip hop be h

   ∵ h = 40 % of n

      h = 40/100 × n

      n = 100/40 × h

      n = 2.5 × h

    ∴ The total no of sixth grade students  = 2.5 times The no of students  

      who said that hip hop is their favorite kind of music

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
