Answer:

Relative Frequency = Observed value for each cell / Total frequency * 100

Cause                       Relative Frequency

Pilot Error                           619

Other human error             85

Weather                              574

Mechanical problems        566

Sabotage                            524

Total                                   2368

The total frequency is 2368

The calculation of the relative frequency distribution is

Cause                          Relative Frequency           Result

Pilot Error                         619/2368 * 100              26.14%

Other human error           85/2368 * 100               3.59%

Weather                            574/2368 * 100             24.24%

Mechanical problems      566/2368 * 100             23.90%

Sabotage                          524/2368 * 100             <u>22.13%</u>

Total                                                                          100%

Conclusion: The most serious threat to aviation safety is the Pilot error as it has the highest frequency. Pilot need to be more equipped with understanding and knowledge of how to deal with unexpected event i.e. turbulence, engine failure among others..

Lorico [155]

Answer:

Emerald’s deduction for organizational expenditures is = $4550

Explanation:

given data

Expenses of temporary director and organizational meeting is = $27,000

Fee paid to state of incorporation = 1,000

Accounting services incident = 15,500

Legal services = 9,500

Expenses incident printing and sale = 6,000

to find out

Emerald deduction for organizational expenditures

solution

first we get here total Qualifying organizational expenditures that is

total Qualifying organizational expenditures  = $27,000 + $1,000 + $15,500 + $9,500

total Qualifying organizational expenditures  = $53000

and Immediate expensing will be as

Immediate expensing = $5000 - ($53000 - $50000)

Immediate expensing = $2000

so now we get here Emerald Corporation deduction under §248 for 2018 is

Amortization = \frac{$53000-$2000}{180} × 9  

here tax in year = 9 month

Amortization = $2550

Emerald’s deduction for organizational expenditures is = $2550 + $2000

Emerald’s deduction for organizational expenditures is = $4550

Advocard [28]

Answer:

Variable cost per unit = $12

The total variable cost = $3,600,000

The total contribution margin = $6,900,000

Explanation:

Number of units produced = 300,000

Selling cost = $35

Revenue = 300,000 × $35

               = $10,500,000

Fixed cost = $14 per unit

Total fixed cost = 300,000 × $14

                          = $4,200,000

Gross margin = $2,700,000

Gross margin is the difference between the Revenue earned and the total cost.

Total cost = $10,500,000 - $2,700,000

                 = $7,800,000

Total cost = Total Fixed cost + Total variable cost

Total variable cost = $7,800,000 - $4,200,000

                               = $3,600,000

Variable cost per unit is the ratio of the total variable cost to the number of units produced.

Variable cost per unit = $3,600,000/300000

                                    = $12

Total contribution margin is the difference between the total revenue and the total variable cost.

Total contribution margin = Total revenue - Total variable cost

                                           = $10,500,000 - $3,600,000

                                           = $6,900,000
