    An inequality question. Please help me. :)

    (x+y)/2 >= sqrt(xy) (x+y+z)/3 = {[(x+y+z)/3 + x]/2 + [y + z]/2}/2 >=[sqrt((x+y+z)x/3) + sqrt(yz)]/2 >=((x+y+z)*(xyz)/3)^(1/4) so [(x+y+z)/3]^4 >= ((x+y+z)*(xyz)/3) [(x+y+z)/3]^3 >= xyz (x+y+z)/3 >cuberoot(xyz) now, the first question is obvious. for the 2nd notice that if k<1...

    Complex Number

    One has the triangle inequality: |A+B|<|A| + |B| or |A+B| - |B| < |A| Then if you let A=z1+z2, B=-z2 you get |z1| - |z2| < |z1 + z2| and if you instead let B=-z1 you get |z2| - |z1| < |z1+z2| combining the 2 you get ||z2| - |z1|| < |z1+z2| equality occurs when z2 = -k*z1 where k is a...

    school rank

    School rank is roughly correlated with performance of school, a rank 1 a james ruse is probably different from a rank one at say.. parramatta high. Combined with School assessment ranks, it gives amateur UAI predictors here a rough feel of a person's ability.
