The following are the equations for the supply and demand curves in the market for weezils: demand: qd = 20 - 2p supply: qs = 5 + 3p where qd is the quantity demanded, qs is the quantity supplied, and p is the price per weezil in dollars. if consumers decide that they want 20 percent fewer weezils at every price, the equation for the new demand curve for weezils will be = 20 - 1.6p qd = 0.2(20 - 2p) qd = 0.8(20 - 2p) qd = 80(20 - 2p)

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.
