Answer:
x = 4
31x + 6 = 130
12x + 2 = 50
Step-by-step explanation:
two angles side by side are equal to 180.
(31x + 6) + (12x + 2) = 180
43x + 8 = 180
43x = 172
x = 4
31x + 6 = 124 + 4 = 130
12x + 2 = 48 + 2 = 50
Answer: The mean is 5
Step-by-step explanation:
If you add all of the numbers and divide by how much numbers there are (8), then you get 5. Then the mean absolute deviation is the number away from the mean.
So I will put the mean absolute deviation in order of the numbers
4 (1 away from mean), 3 (2 away from the mean), 4( 1 away from the mean), 5 (same number as the mean), 6 (1 away from the mean), 6(1 away from mean), 8 (3 away from mean), and, finally another 4 (1 away)
Hope this helps :)
