The line graph provided in the question has the function:
[tex]p=-0.01s^2+0.7s+3.8[/tex]
To find the percentage of students who anticipated a starting salary of $30 thousand, we will identify point 30 on the horizontal axis, trace this point to the line graph, and trace it to the vertical axis. The percentage is the value on the vertical axis.
This is shown below:
The point is approximately 19.
Therefore, the answer is 19%.
