Explanation:

Step1: Analyze the stem-and-leaf plot

In the stem - and - leaf plot, the "Caule" (stem) represents the tens digit and the "Folha" (leaf) represents the units digit. For the number of employees equal to 39, the stem should be 3 (since 3 is the tens digit of 39) and the leaf should be 9 (since 9 is the units digit of 39).

Step2: Count the number of leaves with value 9 for stem 3

Looking at the row where the stem is 3, the leaves are 1, 4, 7, 9, 9, 9. We count the number of 9s in this set of leaves. The number of 9s is 3.

Answer:

3
