I'm doing the exact same one an i got 48 cubic units for the volume. I still have to draw the rectangular figure though.
The mean is 21. The median is 15. The mode is 15. The range is 16.
What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?
For one since since the angles should add up to 180 degrees we must start by adding 55 and 25 which is 80 so 180-80=100 which means c is 100 degrees and for the other I'm going with C
