The number of homicides in five states and five Canadian provinces are given below. State/Province Homicides New Jersey 338 Iowa 52 Alabama 426 Texas 1327 California 2579 Nova Scotia 24 Quebec 32 Ontario 178 Manitoba 31 British Columbia 116 a)  Construct a graph that allows us to compare the number of homicides in each of these states and provinces. Pay attention to the order you put the states/provinces along the x-axis. Make sure to put them in an order that makes it easier to see the pattern. b)  Explain why you chose to put the bars in the order you did.

Draw the graph of four-dimensional cube. How many edges and vertices arethere?

Please solve this problem using a tree diagram. Thank you!

The average degree of a tree is 1.998 (that is, if you sum the degrees of vertices and divide by the number of vertices, you get 1.998). How many vertices does the tree have?

Otitis​ media, or middle ear​ infection, is initially treated with an antibiotic. Researchers have compared two​ antibiotics, A and​ B, for their cost effectiveness. A is​ inexpensive, safe, and effective. B is also safe.​ However, it is considerably more expensive and it is generally more effective. Use the tree diagram to the right​ (where the costs are estimated as the total cost of​ medication, office​ visit, ear​ check, and hours of lost​ work) to answer the following. a. Find the expected cost of using each antibiotic to treat a middle ear infection.   A tree diagram has a root that splits into 2 branches labeled A and B. Primary branch A splits into 2 secondary branches labeled 0.80 Cure 59.30 dollars and 0.20 No cure 96.15 dollars. Primary branch B splits into two secondary branches labeled 0.90 Cure 69.15 dollars and 0.10 No cure 106.00 dollars.0.800.200.900.10 b. To minimize the total expected​ cost, which antibiotic should be​ chosen? a. The expected cost of…

A pipeline network will be built that will connect six cities. Costs (in hundreds million dollars) to build these pipelines depending on the distance shown by the weighted graph below. Find a pipeline system for connecting all cities but with minimal total cost.

In a study of fourth, fifth and sixth graders, the following data were collected on their gender and their primary goal. a) Since data were collected for            variable(s), the correct graph to make is a       b) Which of the following is the correct graph for the above data with Primary Goal grouped by Gender. (If using a screenreader and you cannot see the options, use "message instructor" and include a copy of your graph for hand grading.)
