The lifespans of domesticated cats are normally distributed, with a mean of 15.7 years and a standard deviation of 1.6
years. What is the probability that a given cat will live at
least 15.7 years?

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.
