Answer:
C. Governments have a difficult time fine-tuning the economy by using fiscal policy because there are several time lags and these are often variable.
Explanation:
Fiscal policy includes two important tools, one is taxation and the other is government spending, the balance of which is essential for the sustainable economy, however the collection of expected tax and the nature of spending (also include the priorities) takes time and certain variable factors e.g. economic growth (GDP), employment, inflation, etc makes it difficult for the government to fine tune the economy.
Answer:
the amount of money that must be invested now is $21068.87
Explanation:
Given that:
Nominal interest = 10%
Annuity = 7000
n = 8 years
The Effective interest rate is calculated by using the formula:
Effective interest rate = 
Effective interest rate = 
Effective interest rate = 0.1045
Effective interest rate = 10.45 %
Thus ; the the amount of money that must be invested now is the present value with the annuity of $7, 000 per year for 12 years, starting eight years from now.
PV = 7000 × 6.666056912 × 0.4515171371
PV = $21068.87
Thus; the amount of money that must be invested now is $21068.87
So you still have 60 points to go up. Every month is 3 more points. Divide 60 by 3 which will give you the number of months left before you reach your goal. 60/3= 20 months or 1 year and 8 months.

Answer: 1) collect data, develop hypotheses, and analyze the results.
Explanation:
Scientist are the professional who work in physical science or natural scientist field to gather information ,creates hypothesis for testing or experimentation to know about the actual outcome.
Macroeconomic is the field where overall economy is studied and analyzed to generate studied supposition .From created theory, evaluation of phenomena is done.
Other options are incorrect because unlimited usage of controlled experiment, relying on analyze data nd designing data are not the measure taken by scientist of macroeconomic field .Thus, the correct option is option (1).
