In math, the definition of standard form can be different, depending on whether one means the standard form of a large number or the standard form of different equations. If standard form is in relationship to expressing small or large numbers, then it means using scientific notation. However, when
To calculate the standard deviation, take the square root of the variance. Find the variance by calculating the average of the squared differences from the average of the set.
The 2014 child tax credit is a standard $1,000 credit per child, although there are some limitations. The credit starts to phase out when married couples filing jointly have a modified adjusted gross income of more than $110,000, according H&R Block.
Standard deviation is calculated in Excel by using the formula SDEV(ARRAY), where ARRAY represents the range of numbers for which the standard deviation is being determined. This range is either a row or a column of cells on the Excel worksheet. Like all Excel formulas, SDEV is preceded by an equal
In order to find the length of a curved line, or arc length, it is necessary to know the function of the line. Once this is determined, differentiate the function, plug the equation into the arc length formula, and then integrate the formula.
The standard form of a decimal number places the decimal point after the first digit and then reflects the true size of the number by multiplying it by the appropriate power of 10. This form of a number is also known as its scientific notation form.
To calculate the relative standard deviation, divide the standard deviation by the mean and then multiply the result by 100 to express it as a percentage. The relative standard deviation is also known as the coefficient of variation or the variation coefficient. Engineers and researchers use it to d
The formula for calculating the slope of a line when given two points, (x1, y1) and (x2, y2), is the difference in y coordinates divided by the difference in x coordinates. The slope, denoted as the letter m, equals (y2 - y1)/(x2 - x1).
Standard and Poor ratings are designed to measure the ability for a company to pay off its debt, so the ratings are based on a ratio of the company's assets to debt or liabilities, and on the resources it has to pay off its debt, explains Money Crashers. S&P focuses on the likelihood of a borrower d
Multiply the average number of colonies on an agar plate by the dilution factor to find the number of colony-forming units. Colony-forming units give indication of the number of culturable bacteria and fungi in an aqueous biological sample.
