The percentage of this number of snacks grabbed that is greater than 29, as represented by the stem plot is calculated as: A. 16%.
<h3>How to Solve a Stem Plot?</h3>In a stem plot, each data point is represented as a stem and a leaf, for example, 42 is represented as 4 | 2 on the stem plot.
Given the stem plot for the data of the number of bite-size snacks grabbed by 32 students, the number of snacks grabbed that is greater than 29 are: 32, 32, 34, 38, and 42.
This is 5 out of the total number of the students, which is 32.
Thus, the percentage of this number of snacks grabbed that is greater than 29 would be calculated as:
5/32 × 100 = (5 × 100)/32
= 500/32
= 15.625%
Approximated to the nearest tenth, we would have 16%.
Therefore, the percentage of this number of snacks grabbed that is greater than 29, as represented by the stem plot is: A. 16%.
