Answer:

Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Step-by-step explanation:

How can i solve this<br> (x+2)(2x+3)<br> step by step please
MrRissso [65]

Answer:

2x² + 7x + 6

Step-by-step explanation:

To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).

You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.

(x+2)(2x+3)

2x²+ 3x + 4x + 6

2x² +7x + 6

2x-4y+7=0 how do I find the slope for this?
Digiron [165]

Answer:

The slope is 1/2 and the y intercept is 7/4

Step-by-step explanation:

2x-4y+7=0

To find the slope, we need to put the equation in slope intercept form

y = mx+b

So we need to solve for y

Subtract 2x from each side

2x-2x-4y+7=0-2x

-4y +7 = -2x

Subtract -7

-4y+7-7 = -2x-7

-4y = -2x-7

Divide by -4

-4y/-4 = -2x/-4  -7/-4

y = 1/2 x +7/4

The slope is 1/2 and the y intercept is 7/4
