Answer: 4
Step-by-step explanation:
Answer:
(x, y) = (8, 2)
Step-by-step explanation:
substitute x = 4y into the other equation
2(4y) + 4y = 24
8y + 4y = 24
12y = 24 ( divide both sides by 12 )
y = 2
substitute y = 2 into x = 4y
x = 4 × 2 = 8
solution is (8, 2 )

Answer:
MAD = 2
Step-by-step explanation:
<u><em>First We'll find the mean of data</em></u>
Mean =
Mean = 4
<u><em>Then, we'll find absolute deviation</em></u>
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
<em><u>Now, taking the mean of these absolute deviations:</u></em>
MAD =
MAD =
MAD = 2
