Understanding the Stem-and-Leaf Plot

A stem-and-leaf plot is a type of data visualization that displays the distribution of a dataset. It is a simple and effective way to represent a large dataset in a compact and easy-to-understand format. In this case, we are given a stem-and-leaf plot that lists the number of tropical flowers at the entrance of different parks.

The Data

The stem-and-leaf plot is as follows:

Stem	Leaf
30	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
40	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
50	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
60	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
70	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
80	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
90	0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Analyzing the Data

To find the number of parks that have between 40 and 50 tropical flowers at the entrance, we need to look at the stem-and-leaf plot and identify the parks that fall within this range.

Identifying the Parks with 40-50 Tropical Flowers

Looking at the stem-and-leaf plot, we can see that the stem for 40 is followed by the leaves 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This means that there are 10 parks with 40 tropical flowers at the entrance. Similarly, the stem for 50 is followed by the leaves 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, indicating that there are also 10 parks with 50 tropical flowers at the entrance.

Calculating the Total Number of Parks

To find the total number of parks that have between 40 and 50 tropical flowers at the entrance, we need to add the number of parks with 40 tropical flowers and the number of parks with 50 tropical flowers.

The Final Answer

The total number of parks that have between 40 and 50 tropical flowers at the entrance is 10 + 10 = 20.
