Round all entries inyour answer to two decimal places. (Caution: Because of rounding errors, technologysometimes produces an "inverse" of a singular matrix. These often can be recognized bytheir huge entries. If the inverse doesn't exist, enter DNE in all answer blanks.)−2.52.42.70.20.90.92.0−0.1−0.3
