Answer:
B) 31
Explanation:
Given a stem and leaf plot, you want to identify the minimum value.
Ordering
The values in a stem and leaf plot are ordered with the smallest stems at the top, and the smallest leaves to the left. The smallest value on the plot will be the one at upper left.
Minimum value
The minimum value on this chart has a "stem" of 3 and a "leaf" value of 1. That is the representation of the data value 31.
The minimum temperature shown on the chart is 31.
