What is a double t bar table in math?

I don't use the word phrase myself, but I would venture to say that it is a table with 3 columns. It has the common X value on the left and two different y values on the right. For example you could have time in hours as the X and then money Billy makes at McDonalds in the middle (1st Y) and then money Jenny makes at Burger King on the right. A double t bar table allows a quick comparison of your data.

If your router broadband line light is flashing amber does this mean the line is not yet ready for broadband?

You need to check what the 'broadband light' means. If it means synchronisation then it means that the ADSL (asuming its adsl) signal is not getting to the router. This could be that its not live yet, theres a problem with the line, theres a problem with the filter or wiring etc. If the 'broadband light' is the connection / ppp light then it could be that the username or password are incorrect. I would advise calling your ISP's tech support or having a look in the manual. I use www.odyssey-systems.co.uk for my ADSL and they sent one of their engineers out the same day.

Why use a pie chart over any other chart?

It would depend on your data. Different types of data are suited to different types of charts. A pie chart can only have one series. So you are usually showing how a block of data is split up, like slices in a pie, and how much each element contributes to the whole lot. A company could have its total expenditure, and in slices show how much goes on different aspects of what they spend it on. Slices can be shown with values or with percentages. Surveys showing what percentage of people had particular opinions on an issue would be good for a pie chart.
