Kayla Sarah 5x - 15 - 3x = 10 - (-3x + 20) 5x - 15 - 3x = 10 - (-3x + 20) - 15 - 10.3 - 20 2x - 15 = 10 + 3x - 20 2- 15 = - 10. 3x 2x - 15 = -10 + 3x -3x - 3x 5x - 15 3-10 - 1x - 15 -10 - 15 -15 + 15 +15 - 1x = 5 5x = 5 X=-5 S.

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.
