Asimple graph is called regular if every vertex of this graph has the same degree. a regular graph is called n-regular if every vertex in this graph has degree n. recall that kn is the complete graphs with n vertices. and km, n is the complete bipartite graph (see the definition in the book). (a) is kn regular? what �s the chromatic number of kn? (b) for which values of in and n graph km, n is regular? what is the chromatic number of km, n? (c) how many vertices does a 4-regular graph with 10 edges have?

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
