Step-by-step explanation:

The mean is calculated in the usual way: the sum divided by the number of numbers.

  mean = (5 +9 +5 +5 +7 +11)/6 = 7

The deviations are the differences from the mean:

  deviation = {5, 9, 5, 5, 7, 11} -7 = {-2, 2, -2, -2, 0, 4}

and the absolute deviation is the absolute value of these numbers:

  absolute deviation = {2, 2, 2, 2, 0, 4}

The mean absolute deviation (MAD) is the average of these values:

  (2 +2 +2 +2 +0 +4)/6 = 2

The mean absolute deviation is 2.

It is generally convenient to let technology do the computation. A spreadsheet or graphing calculator can do this easily.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
