Answer:

$0

Explanation:

Probability of getting a six and a tail:

= (1 ÷ 6) × (1 ÷ 2)

= 1 ÷ 12

Probability of not getting a six and a tail:

= 1 - (1 ÷ 12)

= (11 ÷ 12)

Therefore, the expected value is as follows:

= (Probability of getting a six and a tail × Gain) - (Probability of not getting a six and a tail × Lose)

= [(1 ÷ 12) × $110] - [(11 ÷ 12) × $10]

= $0

Hence,

For 45 times,

Money expected = 45 × $0

                            = $0

Many tax professionals and advisors recommend adjusting your W4 allowance so that YOUR TAX PAYMENT WILL EXACTLY MATCH YOUR TAX LIABILITY.
The W4 form is used to claim allowances which one is entitled to. The number of allowance which one claims depends on one's status. Most people under pay or over pay their tax payment as a result of the number of claims that they make. Experts suggest that individuals should adjust their W4 allowance in such a way that over payment and under payment of tax will be avoided.

C. The total cost of commuting from any given distance to work will reduce because the direct cost of the train ticket will fall.

D. The total cost of commuting from any given distance to work will increase because the direct cost of the train ticket will rise

Answer:

A. The total cost of commuting from any given distance to work will reduce because the indirect cost of the commute will fall

Explanation:

Technological advances in wireless communication technology, would reduce the indirect cost of long commutes from any given distance which would cause a reduction in the total cost of commuting, as a function of the effect of geographic area of cities. Direct cost of train ticket would not be affected as the efficiency of the services that train and car riders would offer would increase, as well as the satisfaction they would also enjoy from such technological advances.

Yuliya22 [10]

Answer:

15%

Explanation:

The formula to compute the accounting rate of return is shown below:

= Annual net income ÷ average investment

where,  

Annual net income would be

= Annual revenues - annual expenses

= $68,950 - $40,000

= $28,950

And, the average investment would be

= (Initial investment + salvage value) ÷ 2

= ($310,000 + $76,000) ÷ 2

= $386,000 ÷ 2

= $193,000

Now put these values to the above formula  

So, the rate would equal to

= $28,950 ÷ $193,000

= 15%
