Answer:
Mean = 151
MAD = 9.14
Step-by-step explanation:
Given the data:
135, 160, 145, 155, 170, 150, 142
Mean = Σx / n
Mean = 1057 / 7
Mean = 151
Mean absolute DEVIATION (MAD) : Σ(x - μ) / n
[(135-151) + (160-151) + (145-151) + (155-151) + (170-151) + (150-151) + (142-151)] / 7
Mean absolute deviation = 9.14
m<CAE = 90: definition of perpendicular
p.s. ty for this!
65-9=56
56 divided by 8 is 7
So they will need 7 tents
29 can not be broken down to an even number
Hello, your answer would be (-5, 5)
