FMECA is a bottom-up hardware approach to risk assessment. It is an inductive, or data-driven, linking elements of a failure chain as follows: Effect of Failure, Failure Mode, and Causes/Mechanisms. To estimate the reliability of software, most software prediction models use the probability density function to predict "Mean Time To Failure."

FMECA is a systematic and structured analytical methodology used to identify potential failures in a system, equipment, process, or product, and to assess the effect and probability of those failures. FMECA stands for Failure Modes, Effects, and Criticality Analysis. FMECA is similar to FMEA (Failure Modes and Effects Analysis) in that it is used to identify failure modes and assess their risk.

However, FMECA goes beyond FMEA by analyzing the criticality of each failure mode. This makes it an effective tool for identifying the most significant failure modes and prioritizing them for corrective action. A Probability Density Function (PDF) is a function that describes the likelihood of a random variable taking on a particular value.

PDF is used in software prediction models to estimate the reliability of software by predicting "Mean Time To Failure" (MTTF). MTTF is the average time between failures of a system, equipment, process, or product.

To determine the number of significant discriminant functions and their relative discriminating power in a dataset, a discriminant analysis needs to be performed. Discriminant analysis is a statistical technique used to classify objects or individuals into different groups based on a set of predictor variables.

The number of significant discriminant functions is equal to the number of distinct groups or classes in the dataset minus one. Each discriminant function represents a linear combination of the predictor variables that maximally separates the groups or classes.

The relative discriminating power of each discriminant function can be assessed by examining the Wilks' lambda value or the eigenvalues associated with each function. Wilks' lambda represents the proportion of total variance unexplained by each discriminant function. Smaller values of Wilks' lambda indicate higher discriminating power.

To determine the exact number of significant discriminant functions and their relative discriminating power in a specific dataset, the discriminant analysis needs to be performed using statistical software or tools specifically designed for this analysis.

The value of each variable is:

a = 101°

b = 67°

c = 84°

d = 80°

Since the measure of inscribed angle is half the measure of its intercepted arc. We can say:

100 = 1/2 * (a + 99)

100 * 2 = a + 99

200 = a + 99

a = 200 - 99

a = 101°

Since the opposite angles of cyclic quadrilateral add up to 180°. We can say:

c + 96 = 180

c = 180 - 96

c = 84°

d + 100 = 180

d = 180 - 100

d = 80°

Using inscribed angle theorem:

c = 1/2 * (a + b)

84 = 1/2 * (101 + b)

84 * 2 = 101 + b

168 = 101 + b

You should deposit approximately $340.84 monthly to reach $293,000 in 28 years at a 4.4% annual interest rate compounded monthly.

To calculate the monthly deposit required for an investment plan paying 4.4% interest compounded monthly to reach $293,000 in 28 years, we use the future value of an annuity formula:

FV = P * (((1 + r)^n - 1) / r)

Here, FV is the future value, P is the monthly deposit, r is the monthly interest rate, and n is the number of payments. First, convert the annual interest rate (4.4%) to a monthly rate by dividing by 12, which gives 0.0367 (4.4%/12) or 0.00367 as a decimal. The number of payments (n) is 28 years * 12 months/year = 336.

We want to find P, so rearrange the formula:

P = FV / (((1 + r)^n - 1) / r)

Substitute the values:

P = $293,000 / (((1 + 0.00367)^336 - 1) / 0.00367)

a) The probability that exactly 5 aircrafts arrive in a 1-hour period is 0.0378.

b) The probability that at least 5 aircrafts arrive in a 1-hour period is 0.9329.

c) The probability that at least 10 aircrafts arrive in a 1-hour period is 0.4170.

d) The occurrence probability of an aircraft holding event is 0.6082.

e) The occurrence probability of an aircraft holding event in part (d) as a function of the rate of the Poisson process for rates ranging from 10 to 50 is 0.6754

To calculate this probability, we need to use the Poisson distribution formula in this case, k = 5, λ is the rate parameter (10 per hour), e is the mathematical constant approximately equal to 2.71828, and k! denotes the factorial of k. Plugging in the values, we get:

P(X = 5) = (e⁻¹⁰ x 10⁵) / 5! = 0.0378 (rounded to four decimal places)

One way to do this is to use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring. Therefore, we can write:

P(X ≥ 5) = 1 - P(X < 5) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)]

Using the Poisson distribution formula, we can calculate each of the individual probabilities and then plug them into the equation above. After some calculations, we get:

P(X ≥ 5) = 1 - 0.0671 = 0.9329

To calculate this probability, we can use the same method as in part (b) but with a different lower limit. Specifically, we need to find P(X ≥ 10). Using the complement rule, we can write:

P(X ≥ 10) = 1 - P(X < 10) = 1 - [P(X = 0) + P(X = 1) + ... + P(X = 9)]

Therefore, we get:

P(X ≥ 10) = 1 - 0.5830 = 0.4170

This gives us a rate of 1.67 arrivals per 10 minutes. Using the Poisson distribution formula again, we can calculate the probability of the number of aircraft arrivals exceeding 2 in a 10-minute period:

P(X > 2) = 1 - P(X ≤ 2) = 1 - [P(X = 0) + P(X = 1) + P(X = 2)]

Plugging in the rate parameter of 1.67 and using a calculator, we get:

P(X > 2) = 1 - 0.3918 = 0.6082 (rounded to four decimal places)

Recomputed and plot the occurrence probability of an aircraft holding event in part (d) as a function of the rate of the Poisson process for rates ranging from 10 to 50.

To compute the occurrence probability of an aircraft holding event for different rates, we need to calculate the probability of the number of aircraft arrivals exceeding 2 in a 10-minute period using different rates for the Poisson process. We can write a general formula for this probability as follows:

P(X > 2) = 1 - P(X ≤ 2) = 1 - [P(X = 0) + P(X = 1) + P(X = 2)] = 0.6754

where X is the random variable representing the number of aircraft arrivals in a 10-minute period, and the Poisson rate parameter λ is equal to (rate/6), where rate is the overall rate of aircraft arrivals per hour.

The areas of the two cross-sections would be proportional to k².

If a new cross-section was created in each solid, both at the same height using a scale factor k, the areas of the two cross sections would be proportional to k².

The reason for this is that when a scale factor is applied to a two-dimensional figure, the area of the resulting figure increases by a factor of k². This is because the linear dimensions of the figure (length and width) are multiplied by k, and since the area is calculated by multiplying length and width, the area of the figure is multiplied by k².

Therefore, if the two cross sections are created at the same height and are scaled by the same factor k, their areas will be proportional to k². For example, if k=2, the area of each cross-section will be four times the original area; if k=3, the area of each cross-section will be nine times the original area, and so on.

If the two firms do not cooperate, the payoff that North Springs and South Springs receive in the dominant-strategy equilibrium and the Nash equilibrium would depend on the specific game or scenario being played. Without more information about the specific game being played and the strategies of the two firms, it is impossible to provide a definitive answer.

However, in general, the dominant-strategy equilibrium refers to the situation where each player chooses their best strategy, regardless of what the other player does. The Nash equilibrium refers to the situation where each player chooses their best strategy given what the other player is doing. In some cases, the dominant-strategy equilibrium and the Nash equilibrium may be the same, but in other cases, they may differ.

So, in order to determine the payoff that North Springs and South Springs receive in these equilibria, more information about the game being played and the strategies of the two firms would be needed.
Based on the information given, we can analyze the payoff for both North Springs and South Springs firms in the dominant-strategy equilibrium and the Nash equilibrium.

Dominant-Strategy Equilibrium:
1. Identify each firm's dominant strategy (the best response regardless of the other firm's action).
2. Combine the dominant strategies for both firms to find the outcome.

Nash Equilibrium:
1. Identify each firm's best response given the other firm's action.
2. Find the outcome where both firms are simultaneously choosing their best responses.
