The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.

Parameter and statistic: Parameter is a value that describes the population, while statistic is a value that describes a sample.

Parameters are usually represented using Greek letters, while statistics are usually represented using Roman letters. In other words, a parameter is a population characteristic, whereas a statistic is a sample characteristic.

P and p hat: P represents the true proportion of a population with a particular attribute, while p hat represents the proportion of a sample with that attribute. P hat is an estimate of the true proportion p, which may differ from the actual proportion due to sampling error.

Sampling variability: Sampling variability is the variation in sample statistics that occurs from sample to sample. It is the result of the fact that different samples of the same size drawn from the same population will produce different estimates of the population parameter due to random sampling error. The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.

To find the general solution to the given differential equation using the method of variation of parameters, we can say that the solution may vary depending on the values.

We need to assume a particular solution of the form y_p(t) = u₁(t)y₁(t) + u₂(t)y₂(t), where u₁(t) and u₂(t) are unknown functions to be determined, we can say that the solution may vary depending on the values.

In this specific case, the given differential equation is ty" - (t+1)y' + y = 191². We are told that y₁(t) = e^t and y₂(t) = t+1 are linearly independent solutions to the corresponding homogeneous equation.

To find the particular solution y_p(t) using variation of parameters, we assume y_p(t) = u₁(t)y₁(t) + u₂(t)y₂(t), where u₁(t) and u₂(t) are unknown functions. By substituting this into the differential equation and simplifying, we can obtain expressions for u₁'(t) and u₂'(t). Integrating these expressions with respect to t will give us u₁(t) and u₂(t). After finding u₁(t) and u₂(t), we can form the general solution y(t) = y₁(t) + y₂(t) + y_p(t) by combining the homogeneous solutions y₁(t) and y₂(t) with the particular solution y_p(t). However, if the particular solution y_p(t) is found to be zero, as indicated by y(t) = 0 in the given problem, then the general solution simplifies to y(t) = y₁(t) + y₂(t).

It's important to note that the specific values and calculations for u₁(t) and u₂(t) may vary depending on the given differential equation and the linearly independent solutions y₁(t) and y₂(t) provided.

The integer that describes this difference is 4.

The integer that describes the difference between high tide and low tide, when high tide is 4 feet higher than low tide is 4. The integer is a whole number that can be negative, positive, or zero, but not a fraction or a decimal.Further explanationLet the height of low tide be x. Then the height of high tide will be x + 4.

As per the question, high tide is 4 feet higher than low tide.In terms of an equation,

x + 4 = High tide height= Difference between high tide and low tide

We can calculate the difference between high tide and low tide as follows:

Difference between high tide and low tide = high tide height - low tide height

Difference between high tide and low tide= (x+4) - x= 4

To solve the system Rx = у, where R is an nxn upper triangular matrix with semi-band width s, we can use the back-substitution method, which involves solving for x in the equation R*x = y.

The back-substitution algorithm starts with the last row of the matrix R and solves for the last variable x_n, using the corresponding entry in y and the entries in the last row of R.

Then, it moves on to the second-to-last row of R and solves for the variable x_{n-1} using the entries in the second-to-last row of R, the known values of x_{n}, and the corresponding entry in y. The algorithm continues in this way, moving up the rows of R, until it solves for x_1 using the entries in the first row of R and the known values of x_2 through x_n.

Since R is an upper triangular matrix with semi-band width s, the non-zero entries are confined to the upper-right triangle of the matrix, up to s rows above the diagonal.

This means that in each row of the back-substitution algorithm, we only need to consider at most s+1 entries in R and the corresponding entries in y. Furthermore, since the matrix R is triangular, the entries below the diagonal are zero, which reduces the number of operations needed to solve for each variable.

Thus, in each row of the back-substitution algorithm, we need to perform at most s+1 multiplications and s additions to solve for a single variable. Since there are n variables to solve for, the total number of operations required by the back-substitution algorithm is approximately 2ns flops.

An analogous result holds for lower-triangular systems, where the entries are confined to the lower-left triangle of the matrix. In this case, we use forward-substitution instead of back-substitution to solve for the variables, starting from the first row of the matrix and moving down. The number of operations required is again approximately 2ns flops.

The probability that none of the 4 light bulbs work is 2.56%.

As per the given information, the probability that an individual light bulb works is 0.6.

Therefore, the probability that it does not work (i.e., fails) is:

1 - 0.6 = 0.4

Since each light bulb works independently of the other light bulbs, the probability that none of the 4 light bulbs work is the product of the individual probabilities that each light bulb fails.

Calculated as,

P(none work) = P(first fails) × P(second fails) × P(third fails) × P(fourth fails)

P(none work) = 0.4 × 0.4 × 0.4 × 0.4

P(none work) = 0.0256

Therefore, the probability that none of the 4 light bulbs work is 0.0256 or approximately 2.56%.

tan 36° can be written as cot 54°, which simplifies to (√3 + 1) / (√3 - 1).

The tangent of 36° can be expressed in terms of its cofunction, which is the cotangent. The cotangent of an angle is equal to the reciprocal of the tangent of that angle. Therefore, we can rewrite tan 36° as cot (90° - 36°).

Now, cot (90° - 36°) can be simplified further. The angle 90° - 36° is equal to 54°. So, we have cot 54°.

The cotangent of 54° can be determined using the unit circle or trigonometric identities. In this case, the exact answer for cot 54° is (√3 + 1) / (√3 - 1).

Hence, tan 36° can be written as cot 54°, which simplifies to (√3 + 1) / (√3 - 1).

It is not necessarily true that n(A - B) = n(A) - n(B) when A and B are sets.

Consider two sets, A = {1, 2, 3} and B = {1, 4}.

In this case, A - B = {2, 3}, n(A) = 3, n(B) = 2, and n(A - B) = 2. Therefore, n(A - B) ≠ n(A) - n(B).

In set theory, the difference of two sets A and B is defined as the set of elements in A that are not in B. The cardinality of a set is the number of elements it contains.

The equation n(A - B) = n(A) - n(B) is not always true, and there exist counterexamples where it does not hold. One such counterexample is A = {1, 2, 3} and B = {1, 4}. In this case, A - B = {2, 3}, n(A) = 3, n(B) = 2, and n(A - B) = 2. Thus, n(A - B) ≠ n(A) - n(B).

It is important to note that the equation n(A - B) = n(A) - n(B) holds only when every element in A - B is also in A and not in B. If this condition is not met, the equation does not hold.

Therefore, one must be cautious when applying this equation and ensure that all elements are properly accounted for.

Answer:

Breadth = 20 cm

Area = 800\(cm^{2}\)

Step-by-step explanation:

Perimeter = 120 cm

length = 40 cm

Perimeter = 2 ( L + B )  

L - length     B - Breadth

120 = 2 ( 40 + B )

120 = 80 + 2B

2B = 120 - 80

2B = 40

B = \(\frac{40}{2}\) = 20 cm

Breadth = 20 cm

Area of a reactangle = Length  × Breadth
