Which of the following best explains whether
1/2 or 1 is the better estimate of 36/40?
A.
20
40
=
1
2
and
40
40
=
1
. Since 36 is less than 40,
36
40
is closer to
1
2
than it is to 1.

B.
20
40
=
1
2
and
40
40
=
1
. Since 36 is closer to 20 than it is to 40,
36
40
is closer to
1
2
than it is to 1.

C.
20
40
=
1
2
and
40
40
=
1
. Since 36 is exactly halfway between 20 and 40,
36
40
is as close to
1
2
as it is to 1.

D.
20
40
=
1
2
and
40
40
=
1
. Since 36 is closer to 40 than it is to 20,
36
40
is closer to 1 than it is to
1
2
.

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.
