+-1 , +-1/2, +-2, +-4, +- 5, +- 5/2, +- 10, and +- 20

put in order

+-1/2, +-1 , +-2, +-5/2, +-4, +- 5, , +- 10, and +- 20

answer is

C. +-1/2, +-1 , +-2, +-5/2, +-4, +- 5, , +- 10, and +- 20

and

C. 3 solutions

... i also solved on the other post..

solutions: -5/2, -2 and 2

A square has a perimeter of 36x - 12. Which expression represents one side of the<br> square?

valina [46]

Answer:

9x - 3

Step-by-step explanation:

Hello!

A square has 4 sides.

We can factor out 4 from the expression to find the value of one side.

Factor:

36x - 12
4(9x) - 4(3)
4(9x - 3)

This means that each side of the square is 9x - 3 units long.

A die was rolled eight times. The rolls were 2, 2, 3, 4, 4, 5, 6, and 6. What is the mean absolute deviation for this data? A) 1

adoni [48]

Answer:

The correct option is A:

MAD = 1 + 1/4

Step-by-step explanation:

For a set of N elements {x₁, x₂, ..., xₙ}

The mean is calculated as:

$M = \frac{x_1 + x_2 + ... + x_n}{N}$

And the mean absolute deviation is calculated as:

$MAD = \frac{Ix_1 - MI + Ix_2 - MI + ...+ IX_n - MI}{N}$

Here we have the set of 8 elements:

{ 2, 2, 3, 4, 4, 5, 6, 6}

The mean of this set is:

M = (2 + 2 + 3 + 4 + 4 + 5 + 6 + 6)/8 = 4

Then the mean standard deviation is:

$MAD = \frac{I2 - 4I + I2 - 4I + I3 - 4I + I4 - 4I + I4 - 4I + I5 - 4I + I6 - 4I + I6 - 4I}{8} = 10/8$

If we simplify this, we get:

MAD = 10/8 = 5/4 = (4 + 1)/4 = 4/4 + 1/4 = 1 + 1/4

MAD = 1 + 1/4

The correct option is A.
