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
The height of stack is 36 feet.
<h3>What is unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value
Given:
height of 1 crate = 3 feet
height of 1 crate in inch = 3*12
= 36 feet
Hence, the height of stack of shipping crates is 36 feet.

Answer:
Chris gets £3000
Step-by-step explanation:
A : B : C
1 : 3 : 4 = 8 (add all the parts together)
£6000 ÷ 8 = 750
so the multiplier is x 750
1 : 3 : 4
↩ x 750
750 : 2250 : 3000
Chris gets £3000
No he is not, 10*0.13=1.3, so 5*0.13=0.65
