If you calculated the sum as suggested you can verify this by entering A1110 in any empty cell. Average Function Value The average value of a function f x f x over the interval ab a b is given by f avg 1 ba b a f x dx f a v g 1 b a a b f x d x To see a justification of this formula see the Proof of Various Integral Properties section of the Extras chapter. The average or arithmetic mean is determined by finding the sum of the numbers in the cell range 80 and then dividing the sum by how many numbers make up the range 10 or 80 10 8.
E3x is e 3 x and e 3x is e 3 x.
The mean of a set of numbers is the average of those numbers. If you are given the mean and asked to find a missing number from the set use a simple equation. X j the mean or average is the sum of all x divided by j. Average Value To find the average value of a set of numbers you just add the numbers and divide by the number of numbers.
