Answer 1

@Dianegrace, which choice do you believe is correct?

Answer 2

If I knew I wouldn't be asking.

Answer 3

3|0, 30 that is, occurs in representation A and C but not in the data set, so it cannot be those.

Answer 4

What a stem and leaf plot does is take a list of numbers and organizes them in a sequential fashion, except instead of reordering a set of numbers in the form:
{10, 11, 23, 27, 36, 42}, it organizes that same list in the following manner:

tens|ones
1|0 1
2| 3 7
3| 6
4| 2

Answer 5

Obviously, if a number is not in the list, it is not included in the plot.

Answer 6

Oops. I meant B and D. Furthermore 2|0, 20 that is, occurs only once in A but twice in the data set, so it cannot be that one. That leaves C as the only possible answer.
