Find matrices of orthogonal projections onto all 4 fundamental subspaces of the matrix a = 0 @ 1 1 1 1 3 2 2 4 3 1 a : note, that really you need only to compute 2 of the projections. if you pick an appropriate 2, the other 2 are easy to obtain from them (recall, how the projections onto e and e? are related).

The frequency table shows the results of a survey asking people how many hours they spend online per week. on a piece of paper, draw a histogram to represent the data. then determine which answer choice matches the histogram you drew. in order here is the.. hours online: 0-3, 4-7, 8-11, 12-15, and 16-19. frequency: 5, 8, 10, 8, 7 answer for the question is in the picture! : )
