The regional manager of a chain of department stores created the following stem-and-leaf plot showing the number of pairs of boots at each of the stores:
I 0 I
I 1 I 7 8
I 2 I 0 5 8
I 3 I 4 4 7 8
I 4 I 0
I 5 I
I 6 I
Key: 1 I 7 = 17 pairs of boots
How many department stores have more than 60 pairs of boots?
Can someone help me? I don't even know what a stem and leaf plot is!
the answer is 10
da answer is 0
The answer is 10 because The left column of the stem and leaf plot represents the tens place; each number on the right side represents the ones place for the number of pairs of boots at a department store.
We can combine the tens and ones places and write out the number of pairs of boots at each department store on the right:
Now we know the number of pairs of boots at the different department stores:
17, 181, 20, 25, 28, 34, 34, 37, 38, and 40
There are 10 department stores that match our question.
