Answer:
Explanation:
Given
Probability of a person to not enter into a bar or ducking is 
Probability of a person to enter into a bar
(Probability of a person to not enter into a bar or ducking)
Substituting the given value, we get
Probability of a person to enter into a bar
Total three men attempts to enter into the bar and their course of action is independent of each others
Thus, probability of observing the first two walking into the bar and the third ducking will be equal to the product of individual probabilities
I think it’s A because they have to put it under testing
Answer:
the spending and tax policy that the government pursues to achieve particular macroeconomic goals.
Explanation:
Fiscal policy in economics refers to the use of government expenditures (spending) and revenues (taxation) in order to influence macroeconomic conditions such as Aggregate Demand (AD), inflation, and employment within a country. Fiscal policy is in relation to the Keynesian macroeconomic theory by John Maynard Keynes.
A fiscal policy affects combined demand through changes in government policies, spending and taxation which eventually impacts employment and standard of living plus consumer spending and investment.
Fiscal policy typically includes the spending and tax policy that a government pursues in order to achieve particular macroeconomic goals such as price level, economic growth, Gross Domestic Product (GDP), inflation, unemployment and national income levels with respect to the central bank, demand or supply shocks, government policies, aggregate spending and savings.
According to the Keynesian theory, government spending or expenditures should be increased and taxes should be lowered when faced with a recession, in order to create employment and boost the buying power of consumers.
Generally, an economy will return to its original level of output (production) and price level when the short-run aggregate supply curve falls (decreases) and no changes in monetary and fiscal policies are implemented.
Let X be the time or period needed for an automobile center to finish an oil change.
X ∼ N (17, 2.5)
a)
P(X ≥ 20) = P((X - 17)/5 ≥ (20- 17)/2.5) = P(Z ≥ 1.2) = .1151 *100 = 11.51% is the answer
b)
P(X ≥ x) = 0.07
P (X - 17)/2.5 ≥ (x - 17)/2.5) = 0.07
P (Z ≥ z) = 0.07
look at the z table, 0.07 lies between 1.47 and 1.48, add and then divide you'll get:z = 1.475
1.475 = (x - 17)/2.5
x = 20.6875 ≈ 21 minutes
The answer is negative reinforcement. It is a word termed by B. F. Skinner in his theory of operant conditioning. In negative reinforcement, a reaction or performance is reinforced by ending, eliminating or evading a negative consequence or aversive provocation.
