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.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
