Answer (2)
Calculate the job gain for State and local government: 20696.1 − 16662.1 = 4034.0 .
Since we don't have data for other sectors, the best answer is State and local government.
State and local government gained the most jobs based on the table.
The answer is D.
Explanation
Understanding the Problem The table provides the number of jobs in the Federal government and State and local government sectors for different years. The question asks us to identify which service-providing industry gained the most jobs between 1996 and 2006 from the given options: Educational services, Professional and business services, Retail trade, and State and local government.
Calculating Job Gain for State and Local Government We can calculate the job gain for State and local government between 1996 and 2006 using the data provided in the table. The number of jobs in State and local government in 1996 was 16,662.1, and in 2006 it was 20,696.1.
Determining the Job Gain To find the job gain, we subtract the number of jobs in 1996 from the number of jobs in 2006: 20696.1 − 16662.1 = 4034.0 So, State and local government gained 4034.0 jobs between 1996 and 2006.
Comparing with Other Options The table does not provide data for Educational services, Professional and business services, and Retail trade. Therefore, we cannot directly calculate their job gains. However, since State and local government is one of the options, and we have calculated its job gain, we can compare it to the other options. Without additional information, we cannot determine the job gains for the other three options. Therefore, the best answer we can provide based on the available information is State and local government.
Conclusion Based on the available data, State and local government gained 4034.0 jobs between 1996 and 2006, and we have no data to determine the job gains for the other options. Therefore, the answer is State and local government.
Examples
Understanding job growth in different sectors helps in making informed career decisions and understanding economic trends. For example, if you are considering a career in public service, knowing that state and local government jobs have increased can be a factor in your decision. Similarly, policymakers can use this information to allocate resources and plan for future workforce needs. This type of analysis is fundamental in economics and workforce development, providing insights into where jobs are being created and how the economy is evolving.
Approximately 2.81 × 10²¹ electrons flow through the electric device when a current of 15.0 A is delivered for 30 seconds. This is calculated by first determining the total charge using the current and time and then converting that charge to the number of electrons using the charge of a single electron. The process emphasizes the relationship between current, charge, and the flow of electrons.
