(a) Suppose that a 120-vector a represents the age distribution of the customs in a bank, where a, is the number of customs with i year olds, for i = 1, ..,120. Consider that 1 is one vector, whose elements are equal to 1, and that b is a 120-vector with bị = t. Use words (NOT equations) to explain the meaning of 1'a bTa 1Ta (1) (b) Consider that x, y and z are m-vectors, and that ß is a scalar. Discuss the efficient procedure to compute B(x)"y+B(x)*z. Show the number of additions and the number of multiplications of your suggested procedure.
