Which stem-and-leaf plot represents the data?

15, 16, 15, 48, 48, 63, 15, 29, 16, 30, 48

Step-by-step explanation:

tens is the answer with 11 entries.

We can also show mean of 29.81 after we draw and total then divide by 11.

We draw a stem vertical stem of  numbers 1 -6  and enter;

5,5,5,6,6 next to 1

9 next to 2

0 next to 3

8, 8, 8 next to 4

3 next to 6

We count up the entries and check we have 11 leafs.

If you have multiple questions here we find a pattern that there are

single entries on 2 =29  3 = 30 and stem = 6 = 63  on the formula = 127

the others add up to = 144 for stem = 4=48 entries.

and = 45 for 1=15 entries on same line =12 for 1 = 16

We add these up

127 + 144 + 45 + 12 = 328 for total

If we divide by no of entries = 11

We have 328 /11 = 29.81 mean.

4y - 6 + y^2 - 9 = y^2 + 4y - 15
