Find an equation for the nth term of the arithmetic sequence. -17, -12, -7, -2, answer choices a: an = -17 + 5(n + 2) b: an = -17 + 5(n + 1) c: an = -17 + 5(n - 1) d: an = -17 x 5(n - 1)

Find the solutions for a triangle with a =16, c =12, and b = 63º

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.
