1A Let G be the subgroup of the free abelian group Z4 consisting of all integer vectors (x,y,z,w) such that 2x3y 5z 7w = 0 (a) Determine a linearly independent subset of G which generates G as an abelian group (b) Show that Z4/G is a free abelian group and determine its rank Solution (b) The linear map Z4 7→Z,(x,y,z,w) 7→2x3y 5zIt would be better to be confident that they really relate to your questionSet Z = g(X) Statement (i) of Theorem 1 applies to any two rv's Hence, applying it to Z and Y we obtain EE(ZjY)= E(Z) which is the same as EE(g(X)jY)= E(g(X)) 2 This property may seem to be more general statement than (i) in Theorem 1 The proof above shows that in fact these are equivalent statements 3 Zygotes A D G J M P S V Y Growing Ookinetes B E H K Download Scientific Diagram Gen y gen z
