Answer:

$18.74

Explanation:

the margin of error for a 95% confidence level = Z x (σ / √n)

  • Z for a 95% confidence level = 1.96
  • standard deviation (σ) = $160
  • sample size (n) = 280

the margin of error for a 95% confidence level = 1.96 x ($160 / √280) = 1.96 x ($160 / 16.733) = 1.96 x $9.56 = $18.74

What is the key idea in the aggregate expenditure macroeconomic​ model? The key idea in the aggregate expenditure model is that
guajiro [1.7K]

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.

Zepler [3.9K]

Answer:

WACC = 10.35%

Explanation:

The weighted Average cost of Capital is the average cost of capital for the different sources of long-term capital available to a firm weighted according to the proportion that each source of finance bears to the total capital in the pool..  

After-tax cost of debt = (1- tax rate) × before tax cost of debt  

= (1-0.23)× 7.5% = 5.8%  

Type          Cost (%)       Weight         cost × weight

Equity          12.8              65%               8.32

Debt            5.8                 35%       <u>       2.03  </u>

Total                                                      10.3
