Answer:

The options for this question are the following:

a. 1

b. 2

c. 0.5

d. 1.5

The correct answer is a. 1 .

Explanation:

Group analysis or grouping is the task of grouping a set of objects in such a way that the members of the same group (called a cluster) are more similar, in some sense or another. It is the main task of exploratory data mining and is a common technique in the analysis of statistical data. It is also used in multiple fields such as machine learning, pattern recognition, image analysis, information search and retrieval, bioinformatics, data compression and graphic computing.

Group analysis is not in itself a specific algorithm, but the task pending solution. Clustering can be done using several algorithms that differ significantly in your idea of ​​what constitutes a group and how to find them efficiently. Classical group ideas include small distances between members of the group, dense areas of the data space, intervals or particular statistical distributions. Clustering, therefore, can be formulated as a multi-objective optimization problem. The appropriate algorithm and the values ​​of the parameters (including values ​​such as the distance function to use, a density threshold or the number of expected groups) depend on the set of data analyzed and the use that will be given to the results. Grouping as such is not an automatic task, but an iterative process of data mining or interactive multi-objective optimization that involves trial and failure. It will often be necessary to pre-process the data and adjust the model parameters until the result has the desired properties.

Journal entry for Goodwill is;

Goodwill A/C                             Dr

Net Assets Acquired                 Dr.

     To Purchase Consideration

(Being goodwill recorded)

In the given case, building was acquired for $15,000,000 against it's fair value which was only $7,000,000. The excess price paid for such acquisition represents goodwill which shall be recorded as;

Goodwill A/C ($15,000,000- $7,000,000)  Dr. $8,000,000

             To Building                                                $8,000,000

Assume that Microsoft has no debt, a total market value of $300 billion, and a marginal tax rate of 21%. If it permanently chang
Sphinxa [80]

The presence value of tax shield is =522,000,000

<h3>What is Tax shield?</h3>

Tax shields is calculate by substraction cash flow form two different sessions.

To determine the present value for first session

Market value = $300 billion

Tax rate = 20%

Debt = 0

Tax payable= Tax rate/100% * Market Value

Tax payable = 20/100× $300 billion

= 600,000,000

To get present value of tax

Market value = $300 billion

Tax rate = 20%

Debt = 13% of $300 billion

= 390,000,000

Present Market Value = $300 billon - 390,000,000

= 2,610,000,000 i.e $2.6billion

Tax payable = 20/100 × $2.6 billion

=522,000,000

melomori [17]

Answer:

tax increased = $22.22 billion

so correct option is 3. increase taxes by $22.22 billion.

Explanation:

given data

real GDP = $500 billion

employment GDP = $300 billion

marginal propensity = 0.9

solution

we know here that Inflationary gap will be

Inflationary gap = Real GDP - Full-employment GDP

Inflationary gap = $(500 - 300) billion

Inflationary gap = $200 billion

and tax Multiplier is

Tax Multiplier  = \frac{- marginal propensity}{1 - 0.9}

Tax Multiplier  = -9

here negative sign means that decrease real GDP by $9

so tax should be increased by $1

so we can say that decrease real GDP by $200 billion

and  tax should be increased = \frac{200 billion}{9}  

tax increased = $22.22 billion

so correct option is 3. increase taxes by $22.22 billion.
