Answer:

Top 5 ; Mean = 8.54 ; MAD = 1.752

BOTTOM 5 : Mean = 0.5047 ; MAD = 0.0034

Explanation:

Given the data :

Top 5 : 11, 9.5, 9.5, 7.9, 4.8

Mean, m = Σx / n ; n = sample size = 5

Mean, m = 42.7 / 5 = 8.54

Mean absolute deviation (MAD) : Σ|x - m| / n ;

(|11-8.54| + |9.5-8.54¦ + ¦9.5-8.54| + |7.9-8.54| + |4.8-8.54|) / 5 = 1.752

Bottom 5 : 0.5, 0.502, 0.5045, 0.507, 0.51

Mean, m = Σx / n ; n = sample size = 5

Mean, m = 2.5235 / 5 = 0.5047

Mean absolute deviation (MAD) : Σ|x - m| / n

The mean absolute deviation :0.0034

How are a common denominator and a common multiple alike?
IrinaVladis [17]
First I need to say that the common multiple is when two or more numbers meet up at the same point like 5 and 3 meeting up at 15. The common denominator works almost exactly the same way. It involve two fractions' denominators meeting up like 1/5 and 1/3 meeting up at ?/15 with ? being what the numerator would be (like 1/5 becoming 3/15 because 5 x 3= 15 and you must do so to the numerator so 1 x 3=3. 3/15). So they are alike in the way that they both involve two or more numbers' multiples meeting up, and the common multiple is basically used to find the common denominator.
