To multiply radical expressions with the same index, we use the product rule for radicals. \(\sqrt[n]{A}.\sqrt[n]{B} = \sqrt[n]{A.B}\)

To divide radical expressions with the same index, we use the quotient rule for radicals. \(\frac{\sqrt[n]{A} }{\sqrt[n]{B} } =\sqrt[n]{\frac{A}{B} }\)

Multiplying Radical Expressions :

Example,

given:  Multiply: \(\sqrt[3]{12} .\sqrt[3]{6}\)

Apply the product rule for radicals, and then simplify.

\(\sqrt[3]{12}.\sqrt[3]{6}=\sqrt[3]{12.6}\)

            \(=\sqrt[3]{72}\\=\sqrt[3]{2^{3} .3^{2} } \\=2\sqrt[3]{3^{2} } \\=2\sqrt[3]{9}\)

Dividing Radical Expressions

Example,

given: Divide: \(\frac{\sqrt[3]{96} }{\sqrt[3]{6} }\)

In this case, we can see that 6 and 96 have common factors. If we apply the quotient rule for radicals and write it as a single cube root, we will be able to reduce the fractional radicand.

\(\frac{\sqrt[3]{96} }{\sqrt[3]{6} } =\sqrt[3]{\frac{96}{6} }\)

The correct answers are: The RV can only take two values and the RV results in a success with probability p and in a failure with probability 1-p.

A Bernoulli trial is a random experiment that can result in one of two outcomes, usually referred to as success (S) or failure (F). A random variable that represents the outcome of a Bernoulli trial can only take two values, typically denoted by 1 for success and 0 for failure. The probability of success is denoted by p, and the probability of failure is 1-p.

Therefore, options a and d are incorrect, as they do not necessarily apply to a Bernoulli trial. The RV does not have to take value 0 or 1 with equal probability, and it does not have to be an integer variable.

The number of ways in which 52 cards can be distributed such that Sara receives 17 cards, Jacob receives 17 cards, and their mother receives 18 cards is given by the following expression:52!/17!17!18!

Explanation: The number of ways to distribute k objects among n persons in which the order does not matter and each person receives at least one object is given by the following expression: ((k - n) choose (n - 1)). This can be extended to the case where each person is required to receive a specific number of objects. For example, if we have k objects and want to distribute them to persons A, B, and C such that A receives a objects, B receives b objects, and C receives c objects, where a + b + c = k, then the number of ways to do this is given by the expression: ((k - a - b - c) choose (2))This can be simplified as follows: ((k - a - b - c)!)/((2!)(k - a - b - c - 2)!)), which can be further simplified as follows: (k - a - b - c)(k - a - b - c - 1)/2!.

Therefore, the number of ways in which 52 cards can be distributed such that Sara receives 17 cards, Jacob receives 17 cards, and their mother receives 18 cards is given by: ((52 - 17 - 17 - 18) choose (2))= ((52 - 52) choose (2))= (0 choose 2)=0. Therefore, the required number of ways is 52!/17!17!18!.

Reliability and internal validity are both important concepts in qualitative research, but they refer to different aspects of the research design and findings. Here are the key differences between reliability and internal validity in qualitative research:

Reliability:

1. Reliability refers to the consistency and stability of the research findings. It focuses on the extent to which the study can produce consistent results when the research is conducted again under similar conditions.

2. In qualitative research, reliability is often assessed through methods like inter-coder reliability, where multiple researchers independently analyze the same data and compare their findings to determine the level of agreement.

3. The aim of establishing reliability is to ensure that the findings are not influenced by random errors or variations in data interpretation, and that the results can be replicated or confirmed by other researchers.

4. Reliability is particularly important in ensuring the trustworthiness and credibility of qualitative research, as it enhances the confidence in the accuracy and consistency of the findings.

Internal Validity:

1. Internal validity refers to the extent to which a study provides accurate and valid conclusions about the causal relationship between variables within the specific research context.

2. In qualitative research, internal validity is concerned with factors that may influence the accuracy and validity of the findings, such as researcher bias, participant bias, or threats to the credibility of the data.

3. Researchers strive to establish internal validity by employing rigorous methods such as triangulation, member checking, and reflexivity, to ensure that the interpretations and conclusions are grounded in the data and not distorted by external factors.

4. Internal validity is crucial in qualitative research to establish the trustworthiness and rigor of the study. It ensures that the conclusions drawn from the data are valid within the specific research context and can be confidently attributed to the phenomena being studied.

In summary, reliability focuses on the consistency and stability of the research findings, while internal validity concerns the accuracy and validity of the conclusions drawn from the data. Both concepts are essential for ensuring the quality and trustworthiness of qualitative research, but they address different dimensions of research quality.

Answer:23

Step-by-step explanation:

The correct answer is OA. It is the graph of f(x) translated 11 units to the right.

The transformation g(x) = f(x - 11) represents a horizontal translation of the graph of f(x) = x.

When we substitute x - 11 into the function f(x), it shifts the entire graph 11 units to the right.

This is because for every value of x in f(x), we are now evaluating f(x - 11), which means the x-values are shifted to the right by 11 units.

Therefore, the correct statement is that g(x) is the graph of f(x) translated 11 units to the right.

Answer:

the answer equals 3×7=96

Answer:

number is 10

Step-by-step explanation:

let n be the number, then 4 more than the number is n + 4, thus

n(n + 4) = 140 , that is

n² + 4n = 140 ( subtract 140 from both sides )

n² + 4n - 140 = 0

Consider the factors of the constant term (- 140) which sum to give the coefficient of the n- term (+ 4)

The factors are + 14 and - 10 , since

14 × - 10 = - 140 and 14 - 10 = + 4 , thus

(n + 14)(n - 10) = 0 ← in factored form

Equate each factor to zero and solve for n

n + 14 = 0 ⇒ n = - 14

n - 10 = 0 ⇒ n = 10

Since n is a whole number the the required number is 10

The probability that Angela will roll the die an odd number of times to get three consecutive rolls in order can be calculated by considering the possible outcomes and their probabilities.

To start, let's look at the possible outcomes for Angela to roll the die an odd number of times. For her to achieve three consecutive rolls in order, she needs to roll the die either 1, 3, 5, 7, or any other odd number of times.

Next, let's consider the probability of each of these outcomes:

1. If Angela rolls the die once, she has a 1/6 probability of getting the desired sequence in one roll.

2. If Angela rolls the die three times, she needs to calculate the probability of getting the desired sequence on the third roll. The first two rolls can be any number, but on the third roll, she needs to roll the specific sequence. The probability of getting the desired sequence on the third roll is 1/6.

3. If Angela rolls the die five times, the first four rolls can be any numbers, but on the fifth roll, she needs to roll the specific sequence. The probability of getting the desired sequence on the fifth roll is 1/6.

We can see a pattern here: for Angela to roll the die an odd number of times and achieve the desired sequence, the last roll must be the specific sequence. Therefore, the probability for each odd number of rolls will always be 1/6.

Now, let's calculate the overall probability:

Since Angela can roll the die 1, 3, 5, 7, or any other odd number of times, we need to add up the probabilities for each of these cases. The probability of rolling the die an odd number of times is equal for each case, which is 1/6. Since there are infinitely many possible odd numbers of rolls, we can represent this as the sum of an infinite geometric series.

The probability of rolling the die an odd number of times to get three consecutive rolls in order is therefore:

1/6 + 1/6 + 1/6 + ... (infinitely many terms)

To find the sum of this infinite geometric series, we can use the formula for the sum of an infinite geometric series:

Sum = a / (1 - r)

In this case, a = 1/6 (the first term) and r = 1/6 (the common ratio).

Sum = (1/6) / (1 - 1/6)
Sum = (1/6) / (5/6)
Sum = 1/5

So, the probability that Angela will roll the die an odd number of times and get three consecutive rolls in order is 1/5.

In summary, the probability of rolling the die an odd number of times and achieving three consecutive rolls in order is 1/5.

The mean-square end-to-end distance for the fractal line is ⟨R2⟩ = b².L^(1-D).

The mean-square end-to-end distance for the fractal line is as follows.⟨R2⟩ = ⟨(R(u)- R(v))^2⟩ for u = 0 and v = L where L is the length of the line.⟨R2⟩ = b²/L^2.D.L = b².L^(1-D).

Thus, the mean-square end-to-end distance for the fractal line is ⟨R2⟩ = b².L^(1-D).

The radius of gyration Rg is defined as follows.

Rg² = (1/N)∑_(i=1)^N▒〖(R(i)-R(mean))〗²where N is the number of monomers in the fractal line and R(i) is the position vector of the ith monomer.

R(mean) is the mean position vector of all monomers.

Since the fractal dimension is D, the number of monomers varies with the length of the line as follows.N ~ L^(D).

Therefore, the radius of gyration for the fractal line is Rg² = (1/L^D)∫_0^L▒〖(b/v^(1-D))^2 v dv〗 = b²/L^2.D(1-D). Thus, Rg² = b².L^(2-D).

The ratio R²/Rg² is given by R²/Rg² = L^(D-2).

When D = 1, R²/Rg² = 1/L. When D = 1.7, R²/Rg² = 1/L^0.7. When D = 2, R²/Rg² = 1/L.

This provides information on mean-square end-to-end distance and radius of gyration for fractal line with a given fractal dimension.
