Rectangle ABCD is rotated 180°. What rule shows the input and output of the rotation, and what is the new coordinate of A? O(x, y) + (-X-y): A' is at (5.-1)
O(x, y) -- (-y, x); A' is at (-1,-5)
O(x, y) -- () -x), A' is at (1,5)
O (X, Y) - (x -Y). A' is at (-5, -1)

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
