Answer
Explanation:
Step1: Understand stem - and - leaf plot
In a stem - and - leaf plot, each data value is split into a stem and a leaf. The stem represents the tens digit and the leaf represents the units digit.
Step2: Count the number of data points
For stem 4, there are 2 leaves (46, 48), so 2 data points. For stem 5, there are 3 leaves (53, 56, 58), so 3 data points. For stem 10, there is 1 leaf (102), so 1 data point.
Step3: Sum up the data points
The total number of data points (tanks) with fewer than 110 fish is (2 + 3+1=6).
