No your image is not there.  :(

The first one is right though.

It is a 4 by 4 dot grid.

Ok I'll give it another go.

Here are the options. for the 2 sides that are the same.

across 0 up 1   (1 unit)                 1 possibility as seen on circle below

across 0 up 2  (2 units)                 1 possibility as seen on circle below

across 0 up 3   (3 units)                1 possibility as seen on circle below

across 1 up 1  (sqrt2  units)           1 possibility as seen on circle below

across 1 up 2    (sqrt5 units)           3 possibilities as seen on circle below

across 1 up 3    (sqrt10 units)         2 possibilities as seen on circle below

across 2 up 2     (sqrt8 units)          1 possibility as seen on circle below

across 2 up 3      (sqrt13 units)        2 possibilities as seen on circle below

So unless I made a careless oversight (which is quite possible),  there are  12 possibilities.   

If you become a member it will be easier for people to teach you this.

Yes we can help here.

You only need to learn a little at a time. As you learn things the pace you are learning  will automatically increase.

To make it go to a new line just add in \\  where you want the line break.  :)

I'll write a little simple code.

I want you to copy it and paste it into the latex box but also add \\  (2 backslashes) prior to the 6+8    

Then press ok   

Here is the code:

\text{coding practice please make a new line after this}6+8=14

Give it a go.

I have no idea whay you are getting this message.

But CPhill is right. The message says that if you make an account the problem will be solved. Seems like a relatively painless thing to try.

There are a number of advantages to being a member anyway. 

You lost me here Chris

"The 110°  angle  intercepts a major arc of 220°"

I am really not sure but maybe.

Population: all available cards at stores in Zoe's state

Sample: all available cards at the five stores Zoe shopped at

but it could be

Sample: all available cards at Gifts and More
Population: all available cards at the five stores Zoe shopped at

I'm leaning towards the second one but I really don't know.

All I know for sure is that the population is bigger than the sample :/

Join the alpha vertex to the vertex opposite and then you have two cyclic quads.  (one on top and one underneath)

So alpha is the sum of (180-105)+(180-110) = 75+70=145 degrees

I know this is the same as asad's answer, it is just another way of doing it  (I actually did not understand asad's method.)

Thanks you for responding to me.

ok that is fine and yes it was the LaTex that i was referring to.

It would be a good idea for you to experiment a little and try and work out basic latex coding that will help.

Did you open the latex box in the ribbon and paste the coding into that ?

Or did you enter it some other way?

I just found this.  So it ist is 6.6.6    Iguess that can be writen as 6^3
