When designing a more effective and reliable commercial airline aviation maintenance system for complex work instructions, explain what macroergonomic factors might be considered to prevent dispatch of non-airworthy flights. Also, delineate how system boundaries (e.g., O-level, I-level, depot, scheduled, non-scheduled) would be addressed to assure distributed accountability for all work completed.

In java please Question: You are given a string s. Your task is to count the number of ways of splitting s into three non-empty parts a, b and c (s = a + b + c) in such a way that a + b, b + c and c + a are all different strings. For s = "xzxzx", the output should be countWaysToSplit(s) = 5. Consider all the ways to split s into three non-empty parts:

2019
Variable cost per unit of the product
GH¢2
Selling price per unit
GH¢6
Quantity
4000 units per annum

Test marketing expenses amounts to GH¢3000

Variable cost will increase by 5% per annum

Selling price will increase by 10% per annum

Marketing expense will be 5% of sales revenue per year

An initial working capital investment of GH¢2000 will be made. Subsequently, net working capital at the end of each year will be equal to 10 percent of sales for that year. In the final year of the project, net working capital will decline to zero as the project is wound down. In other words, the investment in working capital is to be completely recovered by the end of the project’s life

As a result of the introduction of the new product, sales of existing products will drop by 1000 units per annum. The selling price per unit of existing products is GH¢5 while the variable cost is GH¢ 4.

Overhead cost will be fixed at GH¢6000 per year

The project will last for five years (2019-2023) and the machines will be sold for a scrap value of GH¢2000

Charge depreciation using the straight line method

CPC falls within the 25% tax bracket

The project cost of capital is 15%

Assume that the regression line for the New York City murder rate per 100,000 residents between 2000 and 2010 is given by y=−0.24x+488.7, where x is the year and y is the murder rate. Interpolate to get an approximate value for the rate in 2006. Round your answer to one decimal place.

Interpolated rate

The table below shows the murder rate per 100,000 residents for a large American city over a twelve-year period.

The table below shows per capita cheese consumption, in pounds, for several years for one American state.

Which of the following is the equation of the regression line for this data?

A. y=−0.595x+1163.4
B. y=1163.4x−0.595
C. y=0.595x−1163.4
D. y=0.595x+1163.4
E. y=1163.4x+0.595
F. y=−0.595x−1163.4

Would you expect the regression line for the price of a camera vs. the number sold to slope up or down, or would it be pretty much horizontal?
