What is the equation for calculating gradient earth science?
Gradient= change in field value divided by the distance
What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
What is the equation used for calculating the area of a square or a rectangle?
Area=Length x width or A= L x W
Is the regression equation a mathematical equation that defines the relationship between two variables?
No. It is an estimated equation that defines the best linear relationship between two variables (or their transforms). If the two variables, x and y were the coordinates of a circle, for example, any method for calculating the regression equation would fail hopelessly.
