for the matrix A=[[4,-4,5-2,3,-33,-3,4]] find

If the mode of observations 5,4,4,3,5,x,3,4,3,5,4,3,5 is 3, then median of the observation is

If the mode of observations 5,4,4,3,5,x,3,4,3,5,4,3,5 is 3, then median of the observation is

If A = [ [ 1 , 2 ] , [ 3 , 4 ] ] & B = [ [ 4 , 2 ] , [ 1 , 1 ] ] , then ( A + B )' is equal to : ( a ) [ [ 5 ,4 ] , [ 4 , 5 ] ] ( b ) [ [ 5 , 4 ] , [ 5 , 5 ] ] ( c ) [ [ 5 , 4 ] , [ 3 , 5 ] ] ( d ) [ [ 5 , 5 ] , [ 4 , 4 ] ]

Show that A=A^(-1) if A[[-1,2,-2],[4,-3,4],[4,-4,5]] Hence find A^(2) .

If A=[[5, 4], [4, 3]] , then A^(-1)=

A=[(3,4),(4,5)],B=[(5,3),(2,1)] then AB is ? .

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

If the mode of the observations 5, 4, 4, 3, 5, x, 3, 4, 3, 5, 4, 3 amd 5 is 3, then find the median of the observations.
