Answer:
3
Step-by-step explanation:
Given the data :
2, 3, 7, 8, 9, 13
2 5
3 4
7 0
8 1
9 2
13 6
The mean, = Σx / n ; n = sample size
Mean = 42 / 6 = 7
The mean absolute deviation = Σ|x - mean| / n
The mean absolute deviation is Hence,
(5 + 4 + 0 + 1 + 2 + 6) / 6
Mean absolute deviation = 18 / 6
Mean absolute deviation = 3
Answer:
x = 13/3
Step-by-step explanation:
12(x - 1) = 40
Distribute
12x -12 = 40
Add 12 to each side
12x -12+12 =40+12
12x = 52
Divid each side by 12
12x/12 =52/12
x = 13/3
<span>(–6, 43) is the solution
</span><span>y = -6x +7
43 = -6(-6) + 7
43 = 36 + 7
43 = 43</span>
ANSWER: (√x-5+7= 11)
X= 21
