Linear equations are a subset of non-linear equations, and the equation 3xy = 9 is a non-linear equation.

The equation 3xy = 9 is not a linear equation. It is a non-linear equation. Linear equations are first-degree equations, meaning that the exponent of all variables is 1. A linear equation is represented in the form y = mx + b, where m and b are constants.

The variables in linear equations are not raised to powers higher than 1, making it easier to graph them. In contrast, non-linear equations are any equations that cannot be written in the form y = mx + b. Non-linear equations have at least one variable with an exponent that is greater than or equal to 2. Non-linear equations are harder to graph than linear equations.

The answer is false, the equation 3xy = 9 is a non-linear equation, not a linear equation. Non-linear equations are any equations that cannot be written in the form y = mx + b. They have at least one variable with an exponent that is greater than or equal to 2.

It would take approximately 6 minutes to travel through the thickest oceanic crust at a speed of 100 km/hr.

To determine the time it would take to travel through the thickest oceanic crust at a speed of 100 km/hr, we need to know the thickness of the oceanic crust.

The oceanic crust is the outermost layer of the ocean floor and is generally thinner than the continental crust. On average, the thickness of the oceanic crust ranges from 5 to 10 kilometers (km). However, the thickness can vary depending on the specific location and geological factors.

Assuming we consider the thickest part of the oceanic crust, which could be up to 10 km thick, we can calculate the time it would take to travel through it at a speed of 100 km/hr.

Using the formula Time = Distance / Speed, we can determine the time as follows:

Time = (Thickness of Oceanic Crust) / (Speed)

Time = 10 km / 100 km/hr = 0.1 hr

Converting 0.1 hour to minutes, we have:

Time = 0.1 hr * 60 min/hr = 6 minutes

The correct answer is D. 6 minutes. This calculation is based on the assumption that we are considering the thickest part of the oceanic crust, which is approximately 10 km thick. It's important to note that the actual thickness of the oceanic crust can vary, and the time required would depend on the specific thickness encountered during the journey.

No, we cannot use the binomial probability formula with x counting the number who are left-handed in this case

This is because the adults surveyed were selected without replacement. The binomial distribution requires that the samples are independent and identically distributed (i.e., the probability of success remains constant for each trial).

However, when we sample without replacement, the probabilities are not constant because the population size changes with each selection. This means that the probability of selecting a left-handed person for the first selection is not the same as the probability of selecting a left-handed person for the second selection, and so on. Therefore, we cannot use the binomial distribution to calculate the probability of at least 30 left-handed adults among 100 selected without replacement from the US population.

Instead, we can use the hypergeometric distribution to calculate the probability of at least 30 left-handed adults among 100 selected without replacement from the US population. The hypergeometric distribution takes into account the changing probabilities as each selection is made without assuming that the selections are independent.

The correct transformation(s) that can be used to map one triangle onto the other are:

1. Translation only

2. Rotation, then translation

Both triangles have congruent sides J K, K L, L M, and M J. To map one triangle onto the other, we can apply a translation, which simply moves the entire triangle in a specific direction, without changing its shape or size.

Alternatively, we can also apply a rotation, followed by a translation, to map one triangle onto the other. This involves rotating one triangle around a fixed point, and then moving it to its final position using a translation. Since the triangles are congruent by SSS, we can use the fact that the corresponding sides are equal in length to determine the amount of rotation needed. The fixed point could be any point, such as the midpoint of KL.

Therefore, the correct transformation options are translation only and rotation, then translation.

The probability of getting two students with the same major is higher for liberal arts majors, followed by business majors, engineering majors, and science majors.

To calculate the probability of getting two specific majors when selecting two students at random, we need to know the total number of students in each major. Let's assume there are 100 engineering majors, 150 business majors, 75 science majors, and 200 liberal arts majors.

The probability of selecting an engineering major as the first student is 100/525 (total number of students). The probability of selecting another engineering major as the second student is 99/524 (one less student in the pool). Multiplying these probabilities gives us 0.036 or 3.6% chance of getting two engineering majors.

Similarly, the probability of getting two business majors is (150/525) * (149/524) = 0.082 or 8.2%, two science majors is (75/525) * (74/524) = 0.023 or 2.3%, and two liberal arts majors is (200/525) * (199/524) = 0.151 or 15.1%.

Therefore, the probability of getting two students with the same major is higher for liberal arts majors, followed by business majors, engineering majors, and science majors.

The probability that a randomly selected student prefers the arts or does not prefer literature is 8/11.

There are different ways to approach this problem, but one possible method is to use the concept of complement events.

First, we can calculate the probability of a randomly selected student preferring the arts. This is simply the proportion of students in the sample who prefer the arts, which is 9 out of 3+9+10 = 22. So, the probability is:

P(arts) = 9/22

Next, we can calculate the probability of a randomly selected student preferring literature. This is the proportion of students in the sample who prefer literature, which is 7+8 = 15 out of 22. So, the probability is:

P(literature) = 15/22

To find the probability of a student preferring the arts or not preferring literature, we can use the complement event that consists of students who do not prefer literature. This is the complement of the event "preferring literature", and its probability is:

P(not literature) = 1 - P(literature) = 1 - 15/22 = 7/22

Finally, we can use the addition rule for disjoint events (i.e., events that cannot occur at the same time) to calculate the probability of the event "preferring the arts or not preferring literature".

Since these events are not mutually exclusive (i.e., some students may prefer both the arts and literature), we need to subtract their intersection (i.e., students who prefer both) to avoid double-counting. Therefore, the probability is:

P(arts or not literature) = P(arts) + P(not literature) - P(arts and literature)

= 9/22 + 7/22 - 0

= 16/22

= 8/11

The probability that you rolled a 5, given that the number rolled was greater than 3, is 1/3 or approximately 0.333.

We need to find the probability that you rolled a 5, given that the number rolled was greater than 3. Let's break this down step by step:

1. Identify the total number of outcomes: Since it is a 6-sided dice, there are 6 possible outcomes (1, 2, 3, 4, 5, and 6).

2. Determine the number of outcomes greater than 3: The outcomes greater than 3 are 4, 5, and 6. There are 3 possible outcomes that satisfy this condition.

3. Identify the number of outcomes that result in rolling a 5: There is only 1 outcome that results in rolling a 5.

4. Calculate the probability: To find the probability, divide the number of outcomes that result in rolling a 5 (1) by the total number of outcomes greater than 3 (3).

Probability = (Number of outcomes with a 5) / (Number of outcomes greater than 3) = 1/3

The probability that the number rolled was a 5, given that it was greater than 3, is \($\frac{1}{3}$\).

The number rolled was greater than 3, it must be either a 4, 5, or 6.

The probability that the number rolled was a 5, given that it was greater than 3.

Let \($A$\) be the event that the number rolled is a 5 and let \($B$\) be the event that the number rolled is greater than 3.

Then, we want to find. \($P(A|B)$\), the probability of \($A$\) given \($B$\).

By Bayes' theorem, we have:

Bayes' theorem (alternatively Bayes' law or Bayes' rule), named after Thomas Bayes, describes the probability of an event, based on prior knowledge of conditions that might be related to the event.

The risk of developing health problems is known to increase with age, Bayes' theorem allows the risk to an individual of a known age to be assessed more accurately by conditioning it relative to their age, rather than simply assuming that the individual is typical of the population as a whole.

One of the many applications of Bayes' theorem is Bayesian inference, a particular approach to statistical inference.

The probabilities involved in the theorem may have different probability interpretations.

Bayesian probability interpretation, the theorem expresses how a degree of belief, expressed as a probability, should rationally change to account for the availability of related evidence.

Bayesian inference is fundamental to Bayesian statistics, being considered by one authority as; "to the theory of probability what Pythagoras's theorem is to geometry."

\($P(A|B) = \frac{P(B|A)P(A)}{P(B)}$\)

\($P(A) = \frac{1}{6}$\), since there is only one way to roll a 5 on a 6-sided die.

\($P(B) = \frac{3}{6} = \frac{1}{2}$\), since there are three outcomes (4, 5, or 6) that satisfy. \($B$\), out of a total of six possible outcomes.

\($P(B|A)$\), the probability of rolling a number greater than 3, given that the number rolled is a 5, note that. \($B$\) is true only if the number rolled is a 4, 5, or 6.

Since there is only one way to roll a 5, and only one of these three outcomes satisfies. \($A$\), we have:

\($P(B|A) = \frac{1}{1} = 1$\)

Substituting these values into Bayes' theorem, we get:

\($P(A|B) = \frac{P(B|A)P(A)}{P(B)} = \frac{1 \cdot \frac{1}{6}}{\frac{1}{2}} = \frac{1}{3}$\)
