Orthogonally diagonalize the matrix, giving an orthogonal matrix p and a diagonal matrix d. to save time, the eigenvalues are - 15 and 4. - -6 3 -1 a= 3 - 14 - 3 - 9 -3 -6 enter the matrices p and d below. (use a comma to separate answers as needed. type exact answers, using radicals as needed. do not label the matrices.)

The box plots show the distributions of the numbers of words per line in an essay printed in two different fonts.which measure of center would be best to compare the data sets? the median is the best measure because both distributions are left-skewed.the mean is the best measure because both distributions are left-skewed.the median is the best measure because both distributions are symmetric.the mean is the best measure because both distributions are symmetric
