The regulation of electric and gas utilities is an important public policy question affecting consumer’s choice and cost of energy provider. To inform deliberation on public policy, data on eight numerical variables have been collected for a group of energy companies. To summarize the data, hierarchical clustering has been executed using Euclidean distance as the similarity measure and Ward’s method as the clustering method. Based on the following dendrogram, what is the most appropriate number of clusters to organize these utility companies? is the most appropriate number of clusters to organize these utility companies.

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
