Arisa [49]
The correct answer is choice C. The mean absolute deviation is a way to show the variability, or how spreadout the data is. When the mean absolute deviations are close to each other, that tells us that they're comparable in how they vary. 6.9 is close to 7.1.

Resolve the expression <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%7D%7B%28x%5E%7B2%7D%20%2B1%29%28x-1%29%5E%7B2%7D%20
Llana [10]

The partial fraction expansion will look like

(<em>x</em> - 2)/((<em>x</em> ² + 1) (<em>x</em> - 1)²) = (<em>ax</em> + <em>b</em>)/(<em>x</em> ² + 1) + <em>c</em>/(<em>x</em> - 1) + <em>d</em>/(<em>x</em> - 1)²

Get everything in terms of a common denominator, and compare the numerators on both sides:

<em>x</em> - 2 = (<em>ax</em> + <em>b</em>) (<em>x</em> - 1)² + <em>c</em> (<em>x</em> ² + 1) (<em>x</em> - 1) + <em>d</em> (<em>x</em> ² + 1)

Expand the right side:

<em>x</em> - 2 = (<em>ax</em> + <em>b</em>) (<em>x</em> - 1)² + <em>c</em> (<em>x</em> ² + 1) (<em>x</em> - 1) + <em>d</em> (<em>x</em> ² + 1)

<em>x</em> - 2 = (<em>a</em> + <em>c</em>) <em>x</em> ³ + (-2<em>a</em> + <em>b</em> - <em>c</em> + <em>d</em>) <em>x</em> ² + (<em>a</em> - 2<em>b</em> + <em>c</em>) <em>x</em> + <em>b</em> - <em>c</em> + <em>d</em>

<em />

Match up the coefficients and solve the resulting system of equations:

<em>a</em> + <em>c</em> = 0

-2<em>a</em> + <em>b</em> - <em>c</em> + <em>d</em> = 0

<em>a</em> - 2<em>b</em> + <em>c</em> = 1

<em>b</em> - <em>c</em> + <em>d</em> = -2

==>   <em>a</em> = -1, <em>b</em> = -1/2, <em>c</em> = 1, <em>d</em> = -1/2

So the expansion into partial fractions is

(<em>x</em> - 2)/((<em>x</em> ² + 1) (<em>x</em> - 1)²) = (-<em>x</em> - 1/2)/(<em>x</em> ² + 1) + 1/(<em>x</em> - 1) - 1/(2 (<em>x</em> - 1)²)

… = -(2<em>x</em> + 1)/(2 (<em>x</em> ² + 1)) + 1/(<em>x</em> - 1) - 1/(2 (<em>x</em> - 1)²)

Please help!! Will mark brainly! Flip the signs if needed.
emmainna [20.7K]

Answer:

1)

5 OVER THE SECOND POWER=25

6XDIVIDEDBY25=4.167

-4 OVER THE THIRD POWER=-64

-64DIVIDEDBY9X=-7.1


2) 7X+8(X-5)

8TIMESX=8X

8TIMES-5=-40

7XPLUS8X=15X

15XDIVIDEDBY-40==2.67

62-12=50

FOR #2THE SIGN WILL BE TURNED THE OTHER WAY.....

3) -12TIMES3/4=-16X

-12TIMES2=-24

-16XDIVIDEDBY-24=1.5

45+3=48

EVERYTHING IN BOLD IS THE AWSNERS I JUST SHOWED MY WORK HOPE THIS HELPS GOOD LUCK.....

How do you preform the indicated operation <br> 14 - (-10) ?
Gemiola [76]

Answer:

\Huge \boxed{24}

Step-by-step explanation:

To solve this problem, first you have to apply the rule of adding numbers from left to right.

\displaystyle -(-c)=c

\displaystyle 14+10

Then, add numbers from left to right.

\displaystyle 14+10=24

As a result, the correct is 24.
