The mean score on the Wechsler IQ test is 100 and the standard deviation is 15. This means that people within one standard deviation of the mean have IQ scores that are 15 points higher or lower than the mean. a. One year, the mean mathematics score on the ACT test was 20.9 with a standard deviation of 5.3. Write an absolute value equation to find the maximum and minimum scores within one standard deviation of the mean. Let t represent the test score.

Hey there!

3(q + 34)= 2

First distribute:

3(q) + 3(34)

3(q) = 3q

3(34) = 102

New equation: 3q + 102 = 2

Subtract by 102 on each of your sides:

3q + 102 - 102 = 2 - 102

Cancel out: 102 - 102 because it gives us 0

Keep: 2 - 102 because it helps us solve for our q

2 - 102 = - 100

New equation: 3q = -100

Divide both sides by 3

3q/3 = -100/3

Cancel out: -3q/3 because it gives us 1

Keep: -100/3 because it gives us the answer for q

q = -100/3 ✅

Good luck on your assignment and enjoy your day!
