Explain Pie Charts ?
If the frequencies are written as percentages, they can be easily compared using a pie chart. The following is an example of a pie chart using the data from the previous two examples:
Step 1: Convert each frequency to a percentage, by dividing the frequency of the events by the total number of events. • The total number of events is 14. • The frequency of {17} is 4. (4+14) 4/14 = 2/7 = 0.2857 = 28.57%• The frequency of {22} is 3.(3+14) = 3/14 = 0.2143 = 21.43%• The frequency of {14 and 15} is 2.(2+14) = 2/14 = 1/7 = 0.1429 = 14.29 %• The frequency of {12, 8, and 9} is 1.(1+14) = 1/14 = 0.0714 = 7.14%

Evaluate following. √16 and Solution To evaluate these first we will convert them to exponent form and then evaluate that since we already know how to
Properties Now there are a couple of formulas for summation notation. 1. here c is any number. Therefore, we can factor constants out of a summation. 2. T
we know that A^m/A^m=1 so A^(m-m)=1 so A^0=1.....
Describe differance between Mean vs. Mode ? Every set of numbers or data has a mean and a mode value. The mean is the average value of all the numbers in the set. The mode is t
