Answer:
3 years
Explanation:
The computation of the time period is shown below
Present value of annuity = Annuity × [1 - (1 + interest rate)^-time period] ÷ rate
$2,000 = $734.42 × [1 - (1.05)^-n] ÷ 0.05
$2,000 = $14,688.4 × [1-(1.05)^-n]
1-(1.05)^-n = ($2000 ÷ $14,688.4)
(1.05)^-n = 1 - ($2000 ÷ $14,688.4)
( 1 ÷ 1.05)^n = 0.86383813
Now take the log to the both sides
n × log(1 ÷ 1.05) = log0.86383813
n = log0.86383813 ÷ log (1 ÷ 1.05)
= 3 years
The possibility of the endless cyclical preference is eliminated by the property of: <span>Transitivity
the property of transitivity follow this exact equation
If a=b ; and b=c ; therefore a=c
This very nature of preference is a core principle of human's opinion, which influence us in making our own choices/</span>
Answer:
The correct answer is binary variables.
Explanation:
A binary variable is one that can only have two possible values. They generally fulfill two essential characteristics:
1. They are made up of two exhausting values, which indicates that there is no other possibility of response. For example, a person is female or male.
2. Both values of the variable are exclusive, that is, it is not possible that both responses can be given, only one. In the same example above, a customer cannot be a woman and a man at the same time.
Answer:
A) in any particular year, the level of GDP is determined mainly by the level of aggregate expenditure.
Explanation:
The formula for calculating the aggregate expenditure (AE) of an economy is the same used to calculate the gross domestic product:
Aggregate expenditures = consumption + investment + government + net exports (exports - imports)
The main difference between the GDP ans AE is that AE measures the planned consumption, the planned investment, the planned government expenses and the planned net exports.
he equation is: AE = C + I + G + NX. The aggregate expenditure determines the total amount that firms and households plan to spend on goods and services at each level of income.
