Step-by-step explanation:
Add all of the numbers up and divide by 8
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:
longer side = √507 cm, shorter side = 13 cm
Step-by-step explanation:
sin60 = opposite side/26cm
opposite side = √507 cm
cos60 = adjacent side/ 26cm
adjacent side = 13 cm
longer side = √507 cm, shorter side = 13 cm
Answer:
8/6 or 4/3
Step-by-step explanation:
Rise divided by run. Rise is difference in y values. 8-0=8
Run is difference in x values 6-0=6
Divide 8/6 then simplify. 4/3
Answer:
There are no solutions
Step-by-step explanation:
2(x+1)=2x+5
Distribute the values on the left:
2x+2=2x+5
subtract 2x from each side
2x(-2x)+2=2x(-2x)+5
2=5
These value are not equal so there are no solutions
