Determine the truth value of the following conjecture. if the conjecture is false, provide a counterexample. given: y = |3x+7| conjecture: y is always even. a. true b. false; absolute value of anything is always odd c. false; when x = –3, y is odd d. false; when x = 2, y is odd

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.
