This probably isn't the "smartest" method, but I just wrote them all out here.

I noticed that they follow a kind of pattern.   

004

013     103

022     112     202

031     121     211     301

040     130     220     310     400

I count fifteen of  them.

What do you want us to do with this?

There are 2 unknowns and only one equation.  So you cannot solve it.

50cos(9x)=-240+15(W+√(57+50sin(9x))/4)

To finish my equation:

3000/2000 = 1.5, using the inverse of tan = 56.3°

No, flat earth theory makes no sense...:)...and thank you! I think one of the things that makes no sense is one person in particular thinks that a sun orbiting over a flat earth at 3000 miles, fits the current path of the sun with a sunrise and sunset and all.

What kind of tax?

GST

PST

Utilty tax

etc.

HAHAHA!!.....yeah...if you're amongst the "Flat Earthers"....then your procedure is "valid"....

Hey CPhill...thanks for the reply!

But the premise is that the earth is flat. Could u respond from that angle, pun intented...:)

a)  Theoretical probability  =  (1/6)100  = about 16 2/3 %  = about 16 times in 100

b) Experimental probability  = 47/100  = 47%

c) The die does not appear to be "fair"......we would expect a "6"  to occur far less frequently in 100 rolls....however.....although we should expect that each number would appear about 16 times in 100 rolls, this, in fact, will probably not happen.....

Actually, because of  the Earth's curvature - and other factors - the procedure is a little more complicated. 

You can read about it here :

6x10^3

1x10^-1  = 6 x 10^4

The answer to the second one is

3x10^4

2x10^0

18 have been selected.....9 have  been orange.....so we expect that the probability that the next marble is orange  is 9/18  = 1/2

What type of calculator are you using? Knowing this information will make it easier to diagnose the problem and fix it.

Normally, I would answer this question, but I have coincidentally found somewhere else where this exact question was asked and answered, so I'll redirect you here:

2029.8 = 0.74686 what is 100%

IF 2,029.8 = 74.686%, then we have:

2,029.8 / 0.74686

=2,717.77843 = 100%

We want to know what  x  values make   2x² - 4x - 6   equal to   0

2x² - 4x - 6  =  0         Divide through by  2  .

x² - 2x - 3  =  0           What two numbers add to  -2  and multiply to  -3  ? →   +1   and   -3 

                                   So...we can factor it like this...

(x + 1)(x - 3)  =  0        Set each factor equal to zero and solve for x.

x + 1  =  0          and          x - 3  =  0

x  =  -1               and          x  =  3

I think this is your question:     \(\sqrt[3]{24} \)

    \(\sqrt[3]{24}\)                                 Split   24   into its prime factors

=  \(\sqrt[3]{2\,*\,2\,*\,2\,*\,3}\)            Rewrite this as...

=  \(\sqrt[3]{2\,*\,2\,*\,2}\,*\,\sqrt[3]{3}\)

=  \(\sqrt[3]{2^3}\,*\,\sqrt[3]3\)                     The cube root of  2  cubed  =  2

=  \(2\sqrt[3]3\)

(1/12 page)/(1/4 minute) = 4/12 page/minute = 1/3 page/minute x 3 minutes = 1 page.

So 3 minutes.

Maybe you need your answers given in radians instead of degrees, or degrees instead of radians?

The graphing calculator should have a setting to put it in degree mode or radian mode.

If you can't find the setting, you can convert from degrees to radians by multiplying by   π / 180

( And you can convert from radians to degrees by mutiplying by   180 / π ).

a)  a combination........combinations count sets......permutations count orderings of sets......here, the order does not matter

b)  C(8,3)  = 56  ways   ....thus 56 different sets

c)  P(3 male)  =  (sets of all possible men) /(all possible sets )  = 

  C(5,3) / C(8,3)  =  10 / 56  =  5 / 28   ≈  17.86 %

     20 %       of  5.00

=   20 / 100   *   5.00

=   0.2 * 5.00

=   1

sin^2θ-csc^2θ=tan^2θ-cot^2θ

This is not an identity

We can see this from the graph, here....
