Answer:

11.04

Step-by-step explanation:

Given the data:

29, 15, 22, 52, 38

The mean absolute deviation :

Mean, m = Σx / n

n = sample size = 5

29 + 15 + 22 + 52 + 38 = 156

Mean = 156 / 5 = 31.2

Mean absolute deviation (MAD):

Σ|x - m| / n

(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5

(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5

55.2 / 5

= 11.04

Find f(g(x)) and g(f(x)) of f(x)=x^2-8, g(x)=2x-5
Zina [86]

f(x)=x^2-8\\\\g(x)=2x-5\\\\f(g(x))\to\text{instead of x write the equation of the function g(x)}\\\\f(g(x))=(2x-5)^2-8=(2x)^2-2(2x)(5)+5^2-8\\\\=4x^2-20x+25-8=4x^2-20x+17\\\\\text{used}\ (a-b)^2=a^2-2ab+b^2

g(f(x))\to\text{instead of x write the equation of the function f(x)}\\\\g(f(x))=2(x^2-8)-5=(2)(x^2)+(2)(-8)-5=2x^2-16-5=2x^2-21

The graph of x squared is the solid black graph below. Which function represents the dotted graph?
Lostsunrise [7]

Answer:

  -1 ≤ y < 6

Step-by-step explanation:

The picture provided has a question of its own. The range of the graph shown is from y=-1 to (almost) y=6. The open circle tells you that the point (-11, 6) is not included in the graph. The range could be written as ...

  range: -1 ≤ y < 6

In interval notations, this is ...

  [-1, 6)

_____

There is no graph of a quadratic, so we cannot answer any questions related to it.
