Think about industry‐disrupting companies such as Uber (disrupting the taxi industry) and Airbnb (disrupting the hotel industry). Research them if you don’t know much about them. What are the legal and ethical issues facing them? In what ways are they being responsible, irresponsible? How would you evaluate their corporate social responsibility?

a) Describe how each of the following can be achieved

i. controlling a DC motor with pulse width modulator.

ii.controlling a stepper motor that has a built-in controller.

Do you agree with the statement that “nothing great would ever be built if people knew in advance what the real costs and challenges were”? please faster

To what extent will built-to-change design principles apply to organizations in other industries with different environments? for example government organisation which are setup with traditional principles?

Cash flow series

Determine the expected present worth of the following cash flow series if each series may be realized with the probability shown at the head of each column. Let i = 20% per year.

The present worth when the probability is 0.3 is $

The present worth when the probability is 0.22 is $

The present worth when the probability is 0.48 is $

The expected present worth value is $  .

When survey data indicated that a coffee company needed to improve its​ package-sealing process, an experiment was conducted to determine the factors in the​ bag-sealing equipment that might be affecting the ease of opening the bags without tearing the inner liner of the bag. Data were collected on 19 bags and the plate gap on the​ bag-sealing equipment was used to predict the tear rating of a bag. Complete parts​ (a) through ​(b).

Bag   Plate gap (X)   Tear rating (Y)
1   -0.3   0.06
2   -0.30   0.03
3   1.80   0.45
4   1.80   0.88
5   0.00   0.31
6   0.30   0.38
7   -0.30   0.77
8   0.00   1.96
9   -0.30   0.22
10   -1.80   0.19
11   -1.50   0.16
12   3.00   3.79
13   -1.80   0.05
14   0.00   0.57
15   -2.40   0.03
16   -1.80   0.12
17   1.50   0.41
18   1.80   4.02
19   0.00   0.09

a. Construct a 95​% confidence interval estimate of the mean tear rating for all bags of coffee when the plate gap is 0.3

b. Construct a 95​% prediction interval of the tear rating for an individual bag of coffee when the plate gap is 0.3
