Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 175 mL of a buffer that is 0.240 M in both formic acid (HCOOH) and its conjugate base (HCOO–). Calculate the maximum volume of 0.380 M HCl that can be added to the buffer before its buffering capacity is lost.

“Flora Lube” is a regional chain that provides a standard service for performing oil changes and basic checkups on automobiles. The chain has a standard that says the average time per car for this service should be 12.5 minutes. There is considerable variability in times due to differences in layout of engines, degree of time pressure from other jobs, and many other sources. As a result, the management of the chain decided to study if the standard is being met and randomly selected 30 oil change and basic checkup services within a month and carefully recorded the time they took in minutes. The resulting data are reported in the following table.

Using the given data and at 3% level of significance, please test whether the chain is achieving its stated standard for the average time for oil change and basic checkup services. Show the necessary steps and explain your conclusion. Is your test result consistent with the conclusion you arrived at based on the 97% confidence interval you constructed under question (a) above? Please explain.

Many of the changes in the welfare system have already reduced and may continue to reduce the number of people receiving welfare. For example, under the current reforms, states receive block grants from the federal government to help finance their welfare programs. This system allows states to save money if they spend less in benefits: reducing benefits does not reduce the amount of federal money they receive. Time limits will also, by definition, reduce the number of people in the program. Allowing beneficiaries to keep their Medicaid coverage if they find a job can also encourage people accepting employment with companies that do not provide health care coverage. Leaving new immigrants without welfare benefits can reduce new welfare rolls as well. Some of the provisions of the reform are directly aimed at discouraging unwed motherhood, including family caps and requirements that teenage mothers live with their parents and stay in school

In preparing Chase City's reconciliation of the Statement of Revenues, Expenditures, and Changes in fund balances to the Government-Wide Statement of Activities, which of the following items should be subtracted from the changes in fund balances?
A. Capital Assets Purchases.
B. Payment of long-term debt principal.
C. Internal Service Fund increase in Net Position.
D. Book value of capital assets sold during the year.
I know the answer is D. Book value of capital assets sold during the year, because the explanation says : At the Governmental-Fund level, the entire proceeds from the sale of capital assets is a financial resource of the fund - it is spendable. Only the gain or loss on the sale of capital assets is reported in the Government-Wide Financial Statements. Therefore, the book value of capital assets should be subtracted.
I don't understand what they mean by this, can please simplify and explain step by step so I can understand?
