How to Find the Sum, Difference, and Product of Two Functions. Step 1: Identify the given functions. Step 2: Find the sum, difference, or product using the following rules: Sum: To find the sum of ...
Square and sum all these differences to get the SSW. Step 3: Calculate the grand mean by taking the mean of all data points regardless of group. If all the groups have the same size, then the ...
The smallest number is 20, and the largest number is 27. (27 - 20) + 1 = 8. Eight numbers make 4 pairs, and the sum of each pair is 47. 4 x 47 = 188.
To find the sum of the infinite series {eq}\displaystyle\sum_{n=1}^{\infty}2(0.25^{n-1}) {/eq}, first identify r: r is 0.25 because this is a geometric series and 0.25 is the number being raised ...
Sum of a Finite Geometric Series Equations and Vocabulary. Sigma notation: This is a shorthand method that represents the adding up of a sequence of terms without writing out every individual term ...
Find the partial sum {eq}S_{25} {/eq} of the arithmetic series: {eq}8,11,14,17,\cdots {/eq} Step 1 : First note that this is an arithmetic series because the difference between any two successive ...
The Sum of a Geometric Series Review. A geometric series is an infinite sum where the ratios of successive terms are equal to the same constant, called a ratio.; If the ratio is between negative ...

Simplify as much as possible to find an explicit formula for the {eq}n {/eq}-th partial sum, {eq}S_n {/eq}. To simplify the result, remove the parentheses and combine terms. Notice that many of ...
The standard deviation of the sum of the two random variables is 2.06. Example 2 Students at State University take a mean of 4 classes per semester, with a standard deviation of 1.5.
