A weighted average is a more accurate measurement of scores or investments that are of relative importance to each other. This is often the case with investment portfolios, grade scoring and other statistics. You can find out how to calculate weighted averages. 1. Sit down with your data, a piece of paper and a pencil.
To specify the boot sequence: 1  Start the computer and press ESC, F1, F2, F8 or F10 during the initial startup screen. 2  Choose to enter BIOS setup. 3  Use the arrow keys to select the BOOT tab.  To give a CD or DVD drive boot sequence priority over the hard drive, move it to the first position in the list.
Unless it is routinely necessary to boot from devices other than the primary hard drive, disable all other boot capabilities. The user can also choose the boot order of enabled devices. 1. Boot the system, and press f10 to enter the BIOS setup. 2. Select Boot options from the System Configuration menu. 3. Select an item from the boot order, and then use the + or â keys to move the item up or down in the priority list (see Figure 3).
