- A checker is placed in the bottom row of a checker board as shown below. It can move diagonally upward. The checker cannot enter the square with an X and also cannot jump over it. How many paths are there to the top of the board? Show your work.arrow_forwarddetermine the number of vertices and edgesand find the in-degree and out-degree of each vertex for thegiven directed multigraph.arrow_forwardEach vertex in the graph represents an animal that needs to be transported to the zoo. Two vertices are connected by an edge whenever the corresponding animals cannot be placed in the same cage (i.e., the edges represent pairs of animals that would harm each other if caged together). What is the fewest number of cages needed to transport these animals? Give a conflict-free way to assign them to cages. S V U W Yarrow_forward

Number of boys and girls in each block: Let's say you want to graph the number of boys and girls in each grade level in a school. You have five grade levels: kindergarten, first grade, second grade, third grade, and fourth grade. In kindergarten, there are 15 boys and 10 girls. In first grade, there are 20 boys and 18 girls. In second grade, there are 12 boys and 14 girls. In third grade, there are 16 boys and 20 girls. In fourth grade, there are 18 boys and 16 girls.Make an appropriate graph for this situation in EXCELShow the steps on how you made itarrow_forward
