Retirees who had different jobs and different income levels.
In stratified sampling, the population is broken up into groups ("strata") that are distinctly <u>different</u> from each other.
Answer:
The correct answer is bivariate correlation, two, direction, strength
Explanation:
The correlation is based on linear association, that is, when the values of one variable increase the values of the other variable can increase or decrease proportionally. For example, height and weight have a positive linear relationship, as height increases the weight increases. If we plot a point with both variables the point cloud will resemble a diagonal if there is a correlation between the variables.
Answer:
Extinction.
Explanation:
Extinction is a technique used by Applied Behavioral Analysis (ABA) that corresponds to the interruption and elimination of the reinforcement of negative behavior whose central objective is to cause undesirable behaviors to be totally eliminated or not to occur again.
So there are criticisms about this discipline technique, as it is considered that the ideal is to present a substitution behavior in addition to just eliminating the negative behavior, since n extinction only positive behaviors are reinforced, and negatives ignored.
emission of greenhouse gases
Greenhouse gases are naturally present in the atmosphere in order to keep the earth warmer by trapping some of the sun's rays on earth. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, and hydrofluorocarbons.
Human activities contribute to the emission of greenhouse gases in the atmosphere through fossil fuel use, industrial processes, and intensive livestock farming, among others. Emission of large amounts of greenhouse gases can increase their natural levels in the atmosphere, possibly resulting to global warming.
Answer:
increasing returns to scale
Explanation:
The biggest barrier for other firms are increasing returns to scale. This is because Eric and Chris have their company already established and also have their clientele all hooked up and using their service. This allows them to produce a much higher electrical output for their clients with a certain Income. Newer companies will need a much higher income just to be able to produce a similar electrical output in order to try and compete with Eric and Chris.
