Compute the Banzhaf power of each voter in the method. Two voting systems are called equivalent if they always have the same winning coalitions. (b) Show that V (5; 4, 3, 2, 1) is not equivalent to V (9; 8, 7, 3, 2).

(c) For what values of x is V (5; 4, 3, 2, 1) equivalent to V (9; 7, 6, 5, x)

Astudent found the solution below for the given inequality. |x-9|< -4 x-9> 4 and x-9< -4 x> 13 and x< 5 which of the following explains whether the student is correct? -the student is completely correct because the student correctly wrote and solved the compound inequality. -the student is partially correct because only one part of the compound inequality is written correctly. -the student is partially correct because the student should have written the statements using “or” instead of “and.” -the student is completely incorrect because there is no solution to this inequality.
