Answer 1

Think of each stem as representing 10 times its value

Ex: a stem of 13| represents 130. The leaf represents the ones place, so 13| Could include all values from 130-139

Now, given that the lowest value is 130 and the highest is 182, what stems do you need?

Answer 2

13, 14, 15, 16, 17, 18?

Answer 3

would it be E?

Answer 4

keep in mind you only need each stem once

for example, you only need to write 14| once, because it can include all values from 140 to 149

Answer 5

So C
