Explain why a solution of a word problem should be checked using the original wording of the problem and not the equation written from the wording.
Choose the correct answer below.
A. It is possible that errors
were made when translating from a word problem to an equation.
B. The math of an equation can not
perfectly translate to a real-life situation so the answer found may be inaccurate.
C. It is not possible to
determine whether an answer is correct based on an equation alone.
D. The units of an equation's answer
have no meaning when taken out of the context of the word problem it relates to

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.
