The equations which represents the minimum and maximum scores of the students is; x = 87 ± 1.8.
<h3>Which equations represents the minimum and maximum possible scores of each student?</h3>
According to the task content, the
Average score of the students in the science class is; 87 points
All students are within 1.8 points of the average,
it therefore follows from the task content that the
minimum score is;
= 87 -1.8
= 85.2
maximum score is;
= 87+1.8
= 88.8 points.
