4. An increase in illegal drug sales.

6. More Americas purchase cars made in Japan. How would each of the following change the GNP? Explain.
7. Bosch (German company) opens a new plant in Columbia, SC.

A complex electronic system is built with a certain number of backup components in its subsystems. One subsystem has four identical components, each with a probability of 0.2 of failing in less than 1000 hours. The subsystem will operate if any two of the four components are operating. Assume that the components operate independently. Find the probability that
(a) exactly two of the four components last longer than 1000 hours.
(b) the subsystem operates longer than 1000 hours.

This week you listened to an episode of “How I built This” featuring AirBnB. This company has an interesting story in that it created a unique business model inside of a competitive hospitality industry. For this assignment you will be analyzing the external environment of AirBnB. Please do whatever additional research is necessary outside of the podcast to satisfactorily answer the following questions. Remember to justify your answers with evidence.
Questions:
1. What area(s) of the general external business environment do you believe changed in order to provide an opportunity for a company like AirBnB to form. Is there a changing area of the general environment that you believe will be a threat to their business model in the future?

A binary search tree can be built with a traditional insertion
method given a list of integers. Binary search trees (BSTs) are
binary trees where the data is ordered such that nodes in the
subtree to the left of a given node are smaller than or equal to
the node, and the right subtree will contain nodes with values
greater than the given node. With a built binary search tree, one
can traverse the tree to print each node’s data in each order of
traversal or perform some other operations. Further, one can tell
by comparing nodes between two given trees whether they relate to
each other, by having a reflected symmetric structure (i.e. being
mirror images of each other), having identical structure, or not
being related at all. In this assignment, you are asked to
implement the following features.
Hard-code some paired lists of integers.
Build binary search trees from each list
Print the binary search trees in the three orders discussed in
class.
Determine if the two binary search trees are identical, mirrors of
each other, or neither
Remove a number in each tree at random and compare the tree pair
again
Further, since the methods of the binary search tree class have
been presented with recursive function calls, it is now up to you
to implement these recursive functions with iterative loops.
NO recursion with the methods. It needs to be done iteratively.

1. How is a brick veneer wall built? What are the correct steps in this process?
2. Why do we need to use an SW brick for an exterior wall in New England? And what type of mortar should we use?

A engine part is built and shipped from a factory. The manager needs to estimate true proportion of parts (p) in the shipment that are mildly defective before the shipment goes out. He takes a sample of n=400n=400 parts and finds that 5% are mildly defective. He has 80% confidence that p lies in a confidence interval (a,b). What is the interval (a,b)?

A newly built casino is introducing a new gamble. Since this game is extremely new, the casino is offering a free play to everyone (no money or chips needed to gamble) so that all players get a sense of this new game. The game is played with the following rules
There are 3 decks of 20 cards each on the table:
• Deck A contains 20 red cards numbered 1–20.
• Deck B contains 10 red cards numbered 21–30 and 10 blue
cards.
• Deck C contains 5 red cards numbered 31–35 and 15 blue
cards.
Each of the 3 decks is shuffled, and 1 card is drawn from each
deck. These 3 cards are shuffled and put
face down on the table, making a new pile of 3 cards. Let R be the
number of red cards among these 3
cards.
a. Compute the expected value and the variance of R.
Parts b–d describe three different ways in which you could learn
that the pile of 3 cards formed above
(with 1 card from each of the 3 decks) has 2 red cards. In each
case, determine the probability that
the third card in the pile is also red. Note that these three parts
are all independent—for example, the
information given in part b does not carry over to parts c or
d.
b. The 3 cards in the new pile are turned over one at a time. The
first card is the red 32, and the
second card is the red 5. What is the probability that the third
card in the pile is also red?
c. The 3 cards in the new pile are turned over one at a time, but
you only see the color on each card
(not the number). The first two cards flipped over are red. What is
the probability that the third
card in the pile is also red?
d. You ask a friend to look at the 3 cards in the pile without
showing you the cards. You ask them,
“Are there at least 2 red cards in the pile?” They confirm that
yes, there are at least 2 reds in the
pile. What is the probability that all 3 cards are red?

Several geothermal power plants are in operation in the united states and more are being built since the heat source of a geothermal plant is hot geothermal water which is “free energy.” An 8-MW geothermal power plant is being considered at a location where geothermal water 160 degrees C is available. Geothermal water is to serve as the heat source for a closed Rankine power cycle with refringent 134a as the working fluid. Specify suitable temperature and pressures for the cycle, and determine the thermal efficiency of the cycle. Justify your selection.
