The AAA Cable Company uses this graph to compare their costs to the costs of a competitor. The competitor charges a $20 installation fee and $1.10 per day. AAA Cable has no installation fee and charges $1.30 per day.

What can be done to make this graph less misleading?

a.
Change the vertical scale to increments of $10 instead of increments of $5.
b.
Change the horizontal scale to increments of 10 days instead of increments of 1 day.
c.
Change the vertical scale to increments of $1 instead of increments of $5.
d.
Change the horizontal scale to increments of One-half days instead of increments of 1 day.

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.
