The two dots above a letter, you mean, would be called a diaeresis and/or an umlaut.
While holding down the alt key you type in 139. When you release the alt key an i with two dots should appear! :)
You spread the dots apart?? Derrrp :D
It is two dots one on top one on bottom and a line in the middle From:Maddie
Difference of two squares.
before or after a DOUBLE BAR
After a note it makes the duration 50% longer (i.e. x 1.5). Thus a dotted half = 3 quarters (instead of two for an un-dotted quarter), a dotted quarter = 3 eighths, etc. A double-dotted note (two dots after it) is 75% longer, so a double-dotted half = 7 eighths (half + a quarter + an eighth). Two dots (vertically) before a double-bar line means repeat back, to either the closest mirror-image dotted double-bar, or (if that's not there) the start.
This is called a repeat sign. It is the 'end repeat'. When you see this, you would go back to the beginning, or to the nearest 'start repeat' sign.
A double bar - a thin line followed by a thick line - signifies the end of a piece of music. On occasion the word "Fine" (fee-nay) accompanies this symbol.
A double bar graph is just like a regular bar graph but it has two bars per subject. Like this:
normally a thin line with another thin line.
The difference between a bar graph and a double bar graph is...... A bar graph displays one set of data, and a double bar graph compares two different sets of information/data.So should have a key.
A double bar graph shows two sets f data in one chart. A bar graph just shows one.
A double bar graph plots two sets of data on a single chart, whereas a bar graph plots just one.
it is for compareing two things
The letter with two dots is called an umlaut and is pronounced by adding a "y" sound before the vowel. For example, "ü" is pronounced like "ue" in German.
Single bonds are represented by the sharing of one pair of electrons between two atoms, drawn as a single line. Double bonds are indicated by the sharing of two pairs of electrons between two atoms, shown as a double line. Triple bonds involve the sharing of three pairs of electrons between two atoms and are represented by three parallel lines.
