Could you elaborate on what you find unsettling in the terms of agreement?

Try the easier one then,

It doesn't really require any calculation, just some thinking. 

As long as we're talking about a function of x, a function has to pass what's known as the vertical line test.....this means that we can't have one "x" value associated with two different "y" values.  This would mean that a vertical line would cut the graph in two different places = not a function.

It is possible to have one y value associated with two different x values - think of a parabola that opens upward or downward.......the graph of that parabola is a function.

...but man, this is inconvenient. When you have a lengthy calculation and see all those long numbers instead of the short character constant it is really, REALLY hard to remember which is which. I think this is horribly inconvenient, not that much different from having to insert them manually.

What is this equal to??   

Otherwise, there's nothing to "solve."

(x-4)/6 = (2x+5)/2

The easiest way to solve this is to just cross multiply...so we have

2(x-4) = 6(2x+5)      Expanding, we have

2x-8 = 12x+30         Subtract 12x from both sides

-10x-8 = 30              Add 8 to both sides

-10x = 38                 Divide both sides by -10

x = -38/10 = -19/5

This page discusses variance and its calculation:

$$\dbinom {4} {2} * \dfrac{1}{2} * \dfrac{1}{2}* \dfrac{1}{2}* \dfrac{1}{2} = \dbinom {4} {2} * \left(\dfrac{1}{2}\right)^4=6*\dfrac{1}{16}=\dfrac{6}{16}=\dfrac{3}{8}=0.375$$

The probability is 37.5 %

Either change the n to x or solve for n!!!

(2n+5)*(n-3) = 2n²-n-15 = 0

so n = -5 or n = 3

Similarly,

2x²-x-15=0 means x = -5 or x = 3

If, on the calculator on the Home page here, you press 2nd and then the const button, you will get a drop-down list of lots of physical constants that you can just select, instead of typing them in.

6/16

To see this notice that a tail could occur on the first flip and then on any of the next three flips. So there are three ways that can happen.

Or, it could occur on the second flip and then on any of the two remaining flips. That's two more ways.

Or, it could occur on the third and on the 4th flips.

So, 3 + 2 + 1 = 6

And there are 2 outcomes possible on each flip, so the total number of outcomes is just 2*2*2*2 = 16

Thus,   6/16

... mod Button?

drop a long time the $$\div$$ Button. He will change to $$\mod$$ Button:

... asin Button?

drop a long time the $$\sin$$ Button. He will change to $$asin$$ Button:

 and so on...

You answered yourself. ^_^

In this case would it be safe to assume this:

$${{\mathtt{642.348}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3.33}}}}\right)} = {\mathtt{6.969\: \!061\: \!341\: \!126\: \!795}}$$

Because Radical usualy means root. And Order.... Well... Order? lol?

Takahiro,

In many countries they use a comma instead of a decimal point.

I think it is reasonabe to assume that in this question the commas are really decimal points.

(I could be wrong but I don't think so)

The only things I can make out of this is Root Order 3 and 33 of Root Order 642 and 348.

Perhaps this could help with solving this equation, if it is what I think he is asking.

Or perhaps it is simplier and it is just a matter of 

$${{\mathtt{33}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)} = {\mathtt{3.207\: \!534\: \!329\: \!995\: \!826}}$$

 and

$${{\mathtt{348}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{642}}}}\right)} = {\mathtt{1.009\: \!157\: \!253\: \!617\: \!218\: \!9}}$$

Yes I know, the question does not make much sense.

I have given you a thumbs up.  I am impressed with your answer. (The effort and the LaTex)

Not many people on the forum can use LaTex as well as you do, I am very glad that you have joined us!

Melody, I see what you have pointed out, but, his question is too confusing so I combined the fraction within the square root

Thank you Takahiro, what a great effort!

I have no idea what the question really is but the square root of negative 64 = 8i

Perhaps the person who posted this can clean it up and introduce brackets so it is easier to read!

Indeed, you will need to rewrite your question. Your questions has a mathematical error. In Maths, you can not put an ampersand in an equation!

I think "&" = "+"

$${\sqrt{{\mathtt{3.33}}{\mathtt{\,\small\textbf+\,}}{\mathtt{642.348}}}} = {\mathtt{25.410\: \!194\: \!804\: \!448\: \!076\: \!1}}$$

Variance in the field of probability is measuring how far a set of numbers is spread out. A variance of zero shows that all the values are identical. Variance will always be a postive number. Always when the variance is small, it indicates that the data tend to be very close to the expected value and therefore close to each other, while a high variance indicates that the data are very spread out around the expected number and from each other.
