Step-by-step explanation: Noah and Gabriel have taken 6 quizzes in English class so far. There are no outliers in their quiz scores. Find the measure of variability for Noah’s scores.
Noah’s scores: 84, 85, 85, 86, 90, 92
Mean: 87
Range: 92 – 84 = 8
Gabriel’s scores: 82, 85, 86, 86, 90, 94
Mean: 87.17
Range: 94 – 82 = 12
MAD: 3.22
What is Noah’s mean absolute deviation?

Step-by-step explanation:
Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24
Problem 13
Comment
Same comment as was given for problem 12
Formula
3x + 2 + 3x - 32 = 180 Collect like terms
Solution
3x + 3x +2 - 32 = 180 Combine
6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
6x/6 = 210/6
x = 35
Answer
x = 35
