You find the mean absolute deviation by first finding the mean, and then subtracting all the values in the data set from that, creating a new data set, and then you find the mean of this new data set.

Example:

3, 2, 5, 9, 4

Mean(add them all, divide by how many there are): (3 + 2 + 5 + 9 + 4)/5 = 4.6

Subtract 4.6 from/to all the values:

4.6 - 3 = 1.6
4.6 - 2 = 2.6
5 - 4.6 = 0.4
9 - 4.6 = 4.4
4.6 - 4 = 0.6

Find the mean of these values:

(1.6 + 2.6 + 0.4 + 4.4 + 0.6)/5 = 1.92

So the mean absolute deviation is 1.92.

Help with number 14 please :))
Degger [83]

Answer:

b = - 5

Step-by-step explanation:

(k + a )(k + x) +  1 = k^2 + kx + ak + ax + 1

I think the way to solve this is to worry about the 36

k^s + 1 + ak should equal 36

We know that a = 2

k^2 + 1 + 2k = 36

k^2 + 2k + 1 - 36 = 0

k^2 + 2k - 35 = 0

(k + 7)(k - 5) = 0

k = -7   is the only acceptable answer. It is given that K < 0.

bx = kx + ax

b = k + a

b = - 7 + 2

b = - 5

adoni [48]

Answer:

3/7

Step-by-step explanation:

The number of possible results are;

1, 2 , 3 , 4 , 5, 6 , 7 = 7

odd numbers here are;

1, 3 , 5 and 7

non-odd numbers are 2, 4 and 6

So the section not labeled with an odd number is 3

Hence the probability here is that;

3/7
