This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic and anti-inflammatory actions of the oil.
A computer graph is a graph in which every two distinct vertices are joined by exactly one edge. The complete graph with n vertices is denoted by Kn. The following are the examples of complete graphs. The graph Kn is regular of degree n-1, and therefore has 1/2n(n-1) edges, by consequence 3 of the handshaking lemma.
Seven of the most common graphs in statistics are listed below: 1  Pareto Diagram or Bar Graph - A bar graph contains a bar for each category of a set of qualitative data. 2  Pie Chart or Circle Graph - A pie chart displays qualitative data in the form of a pie. 3  Histogram - A histogram in another kind of graph that uses bars in its display.
