Consider a company that has an intrusion detection system in half of its systems (50%), has bring your own device (BYOD) for 30% of its employees, and uses three systems (computers 40%, smartphones 25%, and cloud 35%).

The probability of a breach is 11%.

The probability of a breach given there is an intrusion detection is 15%

The probability of a breach given there is no intrusion detection 25%

The probability of a breach given employees’ use their own devices 43%

The probability of a breach given employees use company devices 13%

The probability of a breach given computer systems is 7%

The probability of a breach given smartphone systems is 27%

The probability of a breach given cloud system is 17%

3.a. What is the probability of a breach of company computer systems that have no intrusion detection?

3.b. What are the conditions that result in the highest risk of an attack?

A city manager is considering three strategies for a $1,000 investment. The probable returns are estimated as follows: • Strategy 1: A profit of $5, 000 with a probability of 0.20 and a loss of $1, 000 with a probability of 0.80.

• Strategy 2: A profit of $2, 000 with a probability of 0.40, a profit of $500 with a probability of 0.30 and a loss of $1, 000 with a probability of 0.30.

• Strategy 3: A certain profit of $400.

(a) Which strategy has the highest expected profit?

(b) If the city manager is going to pick only 1 strategy, which of the three strategies would you definitely advise against? Provide specific (numeric) details to support your answer.

Two sport teams A and B, 7 games in total, whoever reaches 4 wins is the winner, if we assume Markov chain, P(A wins game k|A wins game k-1)=p11, P(A wins game k|A lost game k-1)=p01,
How do we use simulation to get P(game 7 is played)?
# p11: A won game k given A won game k-1
# p01: A won game k given A lost game k-1
# p0: A won the first game

Explain how an LC pump is able to deliver a relatively constant pressure with a piston pump.

A piston contains 410 moles of an ideal monatomic gas that initally has a pressure of 2.89

An embossing press in which a single-acting cylinder is used for ejecting the processed parts, with the help of circuit diagrams, describe how the cylinder can be activated using 2/2 and 3/2 valves. Compare the two diagrams with regard to extension and retraction of the piston rod and draw your conclusions. Also, calculate the advancing pressure (p) for a piston rod whose diameter d = 60 mm and with a load weight F = 5 kN. Ignore the resistances for this calculation.

A piston-cylinder device initially contains 75 g of saturated water vapor at 310 kPa . A resistance heater is operated within the cylinder with a current of 0.4 A from a 200 Vsource until the volume doubles. At the same time a heat loss of 2 kJ occurs.
a.Determine the final temperature
(T2).
b. Determine the duration of the process.
c. What-if scenario: What is the final temperature if the piston-cylinder device initially contains saturated liquid water?

A hydraulic lift in a garage has two pistons: a small one of cross-sectional area 4.50cm2 and a large one of cross-sectional area 220cm2 .

There are two parts to this question please give CORRECT answer.

Part A If this lift is designed to raise a 3400-kg car, what minimum force must be applied to the small piston?

Part B If the force is applied through compressed air, what must be the minimum air pressure applied to the small piston?

A piston-cylinder device initially contains 0.20(kg) of steam at 3.5(MPa), 300(C). The steam loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 220C.

A) Sketch the above process on a P-v chart, indicating values

B) Determine the pressureand qualityof the final mixture.

C) Determine the boundary work (in kJ)
