Someone just robbed a bank. the police set a triangular perimeter of 16 kilometers where the robber may be hiding. two of the three coordinates for this triangular perimeter are (2, 2) and (-2, -1). each unit represents a kilometer. the area covered is a 12 square kilometers. which of the following is the third coordinate of the triangular perimeter?

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
