Find P(11
Weegy: The answer should be 0.5375 Note that Z = (X - 15)/3. [ This will standardize the problem. 11 11 - 15 (11 - 15)/3 -1.33 < Z < 0.33 Thus, P(11 < X < 16) = P(-1.33 < Z < 0.33). = P(Z < 0.33) - P(Z < -1.33). = 0.6293 - 0.0918 = 0.5375. ] (More)

z = (x - mu)/(sigma)
-2= (x - 25)/(9)
x=7

So the number x = 7 corresponds to z = -2

Compare and contrast the sociocultural and the political-legal dimensions of the general environment, with particular attention to how forces in one could affect the other.
Weegy: Macroenvironmental variables include sociocultural, technological, political-legal, economic, and international variables. The sociocultural dimensions of the environment consist of customs, lifestyles, [ and values that characterize the society in which the firm operates. Socio-cultural components of the environment influence the ability of the firm to obtain resources, make its goods and services, and function within the society. Sociocultural factors include anything within the context of society that has the potential to affect an organization. Population demographics, rising educational levels, norms and values, and attitudes toward social responsibility are examples of sociocultural variables. The political-legal dimension of the general environment also affects business activity. The philosophy of the political parties in power influences business practices. The legal environment serves to define what organizations can and cannot do at a particular point in time. The macroenvironment consists of forces that originate outside of an organization and generally cannot be altered by actions of the organization. Dimensions of the macroenvironment consist of sociocultural factors, technological factors, political-legal elements, economic factors, and international elements. A firm needs to study these elements of its environment, as they have the potential to affect how the organization should operate to attain and maintain its competitive advantage. ] (More)
