a teacher knows that 80 percent will score no more than 5 points above or below the class average 85 percent on the test which inequality represents the test score of 80 percent of her student.
wouldn't it be 5%?
To find the inequality that represents the test score of 80 percent of the teacher's students, we can start by determining the range of scores that fall within 80 percent.
The question states that 80 percent of the students will score no more than 5 points above or below the class average of 85 percent. This means that the scores will be between 85 - 5 and 85 + 5.
To calculate this range, we subtract and add 5 from the class average:
85 - 5 = 80
85 + 5 = 90
Therefore, the range of scores that fall within 80 percent is from 80 to 90.
Now, let's represent this range of scores using an inequality. Since we are looking for scores between 80 and 90, we can use the greater than or equal to (≥) and less than or equal to (≤) symbols.
The inequality that represents the test scores of 80 percent of the students would be:
80 ≤ x ≤ 90
In this inequality, "x" represents the test score of the students.
Darin is not a subject I have ever heard of.
You have not provided the optional answers.
It should look something like
80 < x < 90
Where x is the test score of 85% of the students.
