Option 4 would be the correct answer
Answer:
equals 56
Step-by-step explanation:
(-1,9) because Y is always the second number and -3*-1=3 so 9=3+6 basically :)
4x - 2y = 14
y = 0.5x -1
Get just one variable on one side for both equations.
4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y
Use the transitive property and then solve for x.
x-2 = 4x-14
12 = 3x
x = 4

Answer:
1. MAD for Jada's data set = 1
Step-by-step explanation:
Mean Absolute Deviation = sum of the distances of each data value from the mean ÷ number of data value
Jada's data set is given as: 4, 4, 4, 6, 6 ,6
Mean = 5
✔️Find the distance between each data value form the mean
4 = |4 - 5| = 1
4 = |4 - 5| = 1
4 = |4 - 5| = 1
6 = |6 - 5| = 1
6 = |6 - 5| = 1
6 = |6 - 5| = 1
✔️Find the sum of the distances of each data value from the mean
1 + 1 + 1 + 1 + 1 + 1 = 6
✔️Find the MAD:
MAD = 6/6
MAD = 1
