Cindy is preparing for a 25-mile charity run hosted by her school's Athletic Club on their home track. In preparation for the ru
n, Cindy has been running in 25-lap sets, recording her lap times as she goes. Cindy feels that she is very well prepared for the run. Looking at her scores, she can see that at least 75% of them are 90 seconds or better, with some as good as 82 seconds. But, she also knows that she has a couple of poor times, one as low as 102 seconds, that will make her total time a bit worse. To further analyze her lap times, Cindy would like to organize them in a box-and-whisker plot. Which of the following plots is most like what Cindy should expect to see, based on what she already knows?
In a geometric progression: a, b, c, d... The common ratio can be obtained using: b/a = c/b = d/c b/a = 112 / 64 = 1.75 c/b = 196 / 112 = 1.75 d/c = 343 / 196 = 1.75 The common ratio = 1.75
We need to see the second step of the proof, so we know what needs to be justified. It would also be nice to see the list of answer choices. I'll never understand how someone who can't answer the question and has to ask someone else can then go ahead and decide that the person helping him only needs to see parts of the question.
