Solution. In a complete graph, each vertex is adjacent to is remaining (n–1) vertices. Hence, each vertex requires a new color. Hence the chromatic number Kn = n.

Step-by-step explanation:The chromatic number of a graph is the smallest number of colors needed to color the vertices of so that no two adjacent vertices share the same color (Skiena 1990, p. 210), i.e., the smallest value of. possible to obtain a k-coloring. Minimal colorings and chromatic numbers for a sample of graphs are illustrated above ...Sol: (a) Chromatic number of Kn is n. The colors of all vertices in Kn are distinct because there is an edge between every two vertices. (b) Chromatic number of Ln is n-2. A valid coloring of Ln is the same as Kn except that (1) the color of 2 is the same as that of 1 and (2) the color of 4 is the same as that of 3.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
