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%
Mary made 34 copies at the local office supply store. The copies cost $0.06 each. What was the total cost of the copies? Multiply 34 by $0.06 to ?nd out the total cost; 34 × $0
Let A be an n×n matrix. Then Show that the set U = {u?R^n : Au = -3un} is a Subspace of R^n
2 of 10 =
What is Graphing Statistics explain ? The number of times that an event occurs is called its frequency. One of the ways that you can compare or display different frequencies is
A boy covered half of distance at 20km/hr and rest at 40kmlhr. calculate his average speed.
Slope of Tangent Line : It is the next major interpretation of the derivative. The slope of the tangent line to f ( x ) at x = a is f ′ ( a ) . Then the tangent line is given by,
Larry purchased 3 pairs of pants for $24 each or have 5 shirts for $18 each. How much did Larry spend? Divide the miles through the time to find the rate; 3,060 ÷ 5 = 612 mph.

Determine dy & Δy if y = cos ( x 2 + 1) - x as x changes from x = 2 to x = 2.03 . Solution Firstly let's deetrmine actual the change in y, Δy . Δy = cos (( 2.03) 2
Probability Distribution for Continuous Random Variables In a continuous distribution, the variable can take any value within a specified range, e.g. 2.21 or 1.64 compared to
