In airline​ applications, failure of a component can result in catastrophe. As a​ result, many airline components utilize someth

ing called triple modular redundancy. This means that a critical component has two backup components that may be utilized should the initial component fail. Suppose a certain critical airline component has a probability of failure of 0.041 and the system that utilizes the component is part of a triple modular redundancy. ​(a) What is the probability that the system does not​ fail? ​(b) Engineers decide to the probability of failure is too high for this system. Use trial and error to determine the minimum number of components that should be included in the system to result in a system that has greater than a 0.99999999 probability of not failing.

Answer:

1.  0.99993108.

2. 6 components.

Step-by-step explanation:

(a)  Probability of 1  component failing = 0.041

So the probability of the whole system failing = 0.041^3.

Therefore the probability of not failing

= 1 - 0.041^3 = 0.99993108.

(b).

Try 5 components:

1 - 0.041^5 = 0.99999988

6:

1 - 0.041^6 = 0.9999999952.

So the answer is 6 components.

Natalka [10]

Answer: a) c(x) = 0.124x + 1.1, b) 13 units

Step-by-step explanation: Revenue function = R(x) = 0.21x

Profit function = p(x) = 0.086 - 1.1

Cost function = c(x) =?

A)

Recall that profit = total revenue - total cost

Hence, total cost = total revenue - profit

c(x) = 0.21x - (0.086x - 1.1)

c(x) = 0.21x - 0.086x + 1.1

c(x) = 0.124x + 1.1

B)

Break even point is the point where total revenue equals total cost

R(x) = c(x)

0.21x = 0.124x + 1.1

0.21x - 0.124x = 1.1

0.086x = 1.1

x = 1.1/0.086

x = 12.79 which is approximately 13 units

A coin is tossed 20 times. It lands heads four times. Compare the experimental probability to its theoretical probability. If th
MrRa [10]

Theoretical probability is based on the likelihood of events.

if a coin is flipped 20 times, and it has landed on heads 4 times, theres a 50% chance it would land on heads the 5th time.

it could be that heads gets more than tails or it could be vise versa.

The probability of getting two heads is 1 in 4.

What is 3/4 + 2/3 ???
erica [24]
To add fractions, first convert them to have equal denominators.

3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)

From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12

Final answer: 17/12 or 1 5/12

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?
Paha777 [63]

Answer:

y = 42

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use an ordered pair from the table.

Using x = 2 when y = 12, then

12 = 2k ( divide both sides by 2 )

6 = k

y = 6x ← equation of variation

When x = 7, then

y = 6 × 7 = 42
