Answer:
The number of art students used more than 6 colors = 8.
Explanation:
The line plot shows the number of different colors that art students used in a colored pencil sketch.
The number of students used 7 colors = 1
The number of students used 8 colors = 2
The number of students used 9 colors = 4
The number of students used 10 colors = 1
We need to find the sum = 1 + 2 + 4 + 1 = 8
So the number of art students used more than 6 colors = 8.
