Answer:

x = -3/2

Step-by-step explanation:

Starting from the simplified form, we can subtract 22x to get ...

6x -56 = -65

6x = -9 . . . . . . . . add 56

x = -9/6 = -3/2 . . . . divide by 6 and simplify

The solution of the equation is x = -3/2.

_____

<em>Check</em>

Substituting -3/2 for x in the original equation, we get ...

4[-3/2 +2(3(-3/2) -7)] = 22(-3/2) -65

4[-3/2 +2(-23/2)] = -33 -65

4[-3/2 -23] = -98

4[-49/2] = -98 . . . . . . . true

The variance of a distribution is 195. What is the standard deviation, rounded to the nearest thousandth?

stiks02 [169]

Given:

The variance of a distribution = 195.

To find:

The standard deviation, rounded to the nearest thousandth.

Solution:

Standard deviation of a distribution is the square root of the variance of the distribution.

Here, the standard deviation of the distribution is

$S.D.=\sqrt{195}$

$S.D.=13.96424$

$S.D.\approx 13.964$

Therefore, the standard deviation is 13.964.

Question:-

Reika [66]

${\huge \underline{{ \fbox \color{red}{A}}{\fbox \color{green}{n}}{\fbox \color{purple}{s}}{\fbox \color{brown}{w}}{\fbox \color{yellow}{e}}{\fbox \color{gray}{r } }}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf \red{ \dfrac{1}{2} + \dfrac{1}{4} = \dfrac{3}{4} }$

Step by step explanation :-

The only thing you have to do is add the numerator to the denominator, in this case you have to add the first ones from the front, which can be these 2+1/4, which would result in 3/4, and this is called the Commutative Property.

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \bf \gray{ \dfrac{1}{2} + \dfrac{1}{4} = \dfrac{1}{4} + \dfrac{1}{2} }}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \bf \green{\dfrac{2 + 1}{4} = \dfrac{1 + 2}{4} }}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\bf \blue{\dfrac{3}{4} = \dfrac{3}{4}} }$

Answer :- The answer is 3/4

¿What is commutative property?

It is to change different ways in order of the addends the result would be the same.

Example :-

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\bf \blue{\dfrac{a}{b} + \dfrac{c}{d}} = {\dfrac{c}{d} + \dfrac{a}{b}} }$

I hope I've helped : )
