Answer:

The common problem i encounter mostly is the statistical modelling problem.

In this scenario we choose best combination of independent variables for the hypothesis testing. the independent variable shows the significant effect on dependent variable so we keep it in modelling.

My null hypothesis would be that there is no significant effect of independent variable on dependent variable.  for my alternative hypothesis there exist is significant effect of independent variable on dependent variable.

Explanation:

Solution

The common problem I face daily is the statistical modelling problem which is the selection of relevant independent variable for prediction modelling.

In this example to select the best combination of independent variables we use hypothesis testing. if the independent variable has significant effect on dependent variable then the independent variable shows the significant effect on dependent variable so we keep it in modelling. In this way the model gets improved.

Since there are always two variables or two categories. hence it has a two sample test.

The Hypothesis can be shown below:

Null hypothesis:

H0:There is no significant effect of independent variable on dependent variable.

Alternative hypothesis:

Ha: There is significant effect of independent variable on dependent variable.

The straight-line depreciation method and the double-declining-balance depreciation method: Multiple Choice Are acceptable for t
fiasKO [112]

Answer:

The straight-line depreciation method and the double-declining-balance depreciation method:

Produce the same total depreciation over an asset's useful life.

Explanation:

The straight-line and the double-declining-balance depreciation methods are two of the four depreciation methods allowed by US generally accepted accounting principles (GAAP).  The other two methods are sum of the years' digit and units of production.  The straight-line method is calculated by subtracting the salvage value from the asset's cost and either dividing the depreciable amount by the number of years or applying a fixed rate on the depreciable amount.  For the double-declining-balance method, 100% is divided by the number of years of the asset's useful life and then multiplying by 2 to obtain the depreciation rate.  Depreciation expense is then calculated on the declining balance until the salvage value is left.  This is why they produce the same depreciation over the asset's useful life.

emmainna [20.7K]
A fair value option is the alternative  for a business to record its financial instruments at the fair values. Liabilities are company's financial debts or obligations that arise in the course of business operations. They may be long term or short term. In this case, if the fair value of the liability decreases, the firm should respond by crediting the unrealized Holding Gain/loss in the income account.

maksim [4K]

Answer:

c) $767,464.54

Explanation:

The computation of the future value of an annuity is shown below:

As we know that

Future value of annuity F =  Payment made × ((1 + rate of interest)^t - 1) ÷ r ate of interest

= $3,400 × (1.092^35 - 1) ÷ 0.092

= $3,400 × 225.7249

= $767,464.54

Hence, the future value of an annuity is $767,464.54

Therefore the correct option is c.
