34.03 A triangle on a coordinate plane is translated according to the rule T-3.5(x, y). Which is another way to write this rule?
(x, y) = (x – 3, y + 5)
O(x, y) = (x-3, y-5)
(x, y) = (x + 3, y-5)
(x, y) - (x + 3, y + 5)

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.
