Dead on arrival (DOA), also dead in the field and brought in dead (BID), is a term used to indicate that a patient was found to be already clinically dead upon the arrival of professional medical assistance, often in the form of first responders such as emergency medical technicians, paramedics, or police.
To convert a number to scientific notation, move the decimal point right or left to make the number greater than or equal to one but less than ten, and record the number of poâ¦sitions moved as a power of 10 - the exponent. That is, if the decimal point moves to the left by n positions, then the exponent is 10n.
Scientific notation is used to express very large or very small numbers. A number in scientific notation is written as the product of a number (integer or decimal) and a power of 10. This number is always 1 or more and less than 10. For example, there are approximately 6,000,000,000 humans on earth. This number could be written in scientific notation as 6x109. The number 6,000,000,000 is equivalent to 6*1,000,000,000. The number 1,000,000,000 is equivalent to 109 or 10*10*10*10*10*10*10*10*10.
