Answer:

  • 3096

Step-by-step explanation:

<u>Given:</u>

  • 3x-\frac{1}{4y}=24

<u>Rewrite it as:</u>

  • 3x=\frac{1}{4y}+24
  • x=\frac{1}{12y}+8

<u>Simplify the expression:</u>

  • 8x(6x - \frac{1}{y} ) + \frac{1}{12y^2} (4 - 3y + 36xy^2) =
  • 8(\frac{1}{12y}+8)(6(\frac{1}{12y}+8) - \frac{1}{y} ) + \frac{1}{3y^2}  - \frac{1}{4y}  + 3x =
  • 8(\frac{1}{12y}+8)(48- \frac{1}{2y} ) + \frac{1}{3y^2}  - \frac{1}{4y}  + 24 + \frac{1}{4y}  =
  • 8(\frac{4}{y}+8*48- \frac{1}{24y^2} -\frac{4}{y} ) + \frac{1}{3y^2}  + 24  =
  • 8(384-\frac{1}{24y^2}) + \frac{1}{3y^2}  + 24  =
  • 8*384-\frac{1}{3y^2} + \frac{1}{3y^2}  + 24  =
  • 3072+24=

vovangra [49]

Answer:

456

Step-by-step explanation:

Let X be the SATscore scored by the students

Given that X is normal (1000,200)

By converting into standard normal variate we can say that

z=\frac{x-1000}{200} is N(0,1)

To find the top 10% we consider the 90th percentile for z score

Z 90th percentile = 1.28

X= 200+1.28(200)\\= 200+256\\=456

i.e. only students who scored 456 or above only should be considered.
