An absolute value inequality to find the range of SAT mathematics test scores within one standard deviation of the mean is; |x – 515| ≤ 114
<h3>How to Write Inequalities?</h3>
A) We are told that;
Mean score = 515
Standard deviation = 114
We are now given that people within one deviation of the mean have SAT math scores that are no more than 114 points higher or 114 points lower than the mean. Thus, the absolute value inequality is;
|x – 515| ≤ 114
B) The range of scores to within ±2 standard deviations of the mean is;
Range = 515 ± 2(114)
Range = 287 to 743

Answer: I think it is 40%
Answer:
$5,100
Step-by-step explanation:
total amount of the loan: $13,600
part paid: 
The question is how much of the $13,600 does the that they already paid represent.
For this we need to multiply by 13,600 :
we found that three eighths of $13,600 is equal to $5,100.
Thus they have paid off $5,100 of the loan.
