The statement that non-normality of the residuals from a regression can best be detected by looking at the residual plots against the fitted y values is a false statement.

We have a statement and we need to find out if it is true. A negative residual indicates that the model did not fit. This means that the error produced by the model is not the same between variables and observations (that is error is not random). The content is not regular, that is, the content is distributed regularly and we can conclude that the linear model is the appropriate model. If the subject sees a curvilinear pattern such as a U-shaped pattern, we can conclude that a linear pattern is not suitable and a non-linear pattern would be better. These charts are useful for identifying inconsistencies, inconsistencies in error variance, and inconsistencies. Two well-known tests for normality of residues are the Kolmogorov Smirnov test and the Shapiro-Wilk test. So, residual plot can't be used to check the non-normality of the residuals from a regression. Therefore, it is false statement.

Answer:

Step-by-step explanation:

a. The probability of selecting a purple marble on the first draw is 7/9. Since the marble is not replaced, there are 6 purple marbles and 1 white marble left in the bag. The probability of selecting a white marble on the second draw is 2/7. Therefore, the probability of selecting a purple marble and then a white marble is (7/9) * (2/7) = 2/9.

b. The probability of selecting a white marble on the first draw is 2/9. Since the marble is not replaced, there is only 1 white marble left in the bag. The probability of selecting a white marble on the second draw is 1/8. Therefore, the probability of selecting two white marbles is (2/9) * (1/8) = 1/36.

c. To compare the probability of selecting two white marbles in a row and two purple marbles in a row, we need to calculate the probabilities of each event separately. The probability of selecting two white marbles in a row is 1/36, as calculated in part (b).

The probability of selecting two purple marbles in a row is (7/9) * (6/8) = 21/36, since there are 7 purple marbles and 9 total marbles on the first draw, and then 6 purple marbles and 8 total marbles on the second draw (assuming the first marble was not replaced).

Therefore, there is a greater chance of selecting two purple marbles in a row than two white marbles in a row.

The partial derivative diffusivity equation for spherical flow is ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t, and for hemispherical flow, it is the same equation.

1. The partial derivative diffusivity equation for spherical flow is derived from the spherical coordinate system and applies to radial flow in a spherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

2. The partial derivative diffusivity equation for hemispherical flow is derived from the hemispherical coordinate system and applies to radial flow in a hemispherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

1. For the derivation of the partial derivative diffusivity equation for spherical flow, we consider a spherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the polar angle (φ). By assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in spherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

2. Similarly, for the derivation of the partial derivative diffusivity equation for hemispherical flow, we consider a hemispherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the elevation angle (ε). Again, assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in hemispherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

In both cases, the term ϕμC/k ∂p/∂t represents the source or sink term, where ϕ is the porosity, μ is the fluid viscosity, C is the compressibility, k is the permeability, and ∂p/∂t is the change in pressure over time.

These equations are commonly used in fluid mechanics and petroleum engineering to describe radial flow behavior in spherical and hemispherical geometries, respectively.

The value of x is approximately 9.8.

In this question, we are given an equation, and we need to find the value of x in the equation.

The equation that is given to us is as follows: 19 cos 20° + x = 29

To find the value of x, we need to isolate it on one side of the equation.

First, we will subtract 19 cos 20° from both sides of the equation.

This gives us: x = 29 - 19 cos 20°Now we can use a calculator to evaluate the right-hand side of the equation.

Rounding to the nearest tenth, we get: x ≈ 9.8

Therefore, the value of x is approximately 9.8.

A simple difference is also called a marginal means difference. Option B

In experimental design and statistical analysis, a simple difference refers to the comparison of means between two groups or conditions. It represents the difference in average scores or values between the groups being compared. It is often used to assess the impact of an independent variable on a dependent variable by examining the variation in means between different levels of the independent variable.

The term "marginal means difference" emphasizes that the comparison is based on the average or marginal means of the groups being compared. It helps to distinguish it from other types of differences, such as interaction effects or main effects, which involve more complex comparisons or analyses in factorial designs.

Overall, a simple difference or marginal means difference is a straightforward way to evaluate the effect of an independent variable on a dependent variable by comparing the average values between different groups or conditions.

Answer:

axis of symmtery: x = 3 or h = 3

Step-by-step explanation:

The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.

Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.

Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.

(1) The probability that at least 5 of them started smoking before 21 years of age isThe probability of at least 5 smokers out of 14 to start smoking before 21 is the probability of 5 or more smokers out of 14 smokers who started smoking before 21.  Using the complement rule to find this probability: 1-P(X≤4) =1-0.0003

=0.9997Therefore, the probability that at least 5 of them started smoking before 21 years of age is 0.9997.

(2) The probability that at most 11 of them started smoking before 21 years of age isThe probability of at most 11 smokers out of 14 to start smoking before 21 is the probability of 11 or fewer smokers out of 14 smokers who started smoking before 21. Using the cumulative distribution function of the binomial distribution, we have:P(X ≤ 11) = binomcdf(14,0.9,11)

=0.9982

Therefore, the probability that at most 11 of them started smoking before 21 years of age is 0.9982.(3) The probability that exactly 13 of them started smoking before 21 years of age isThe probability of exactly 13 smokers out of 14 to start smoking before 21 is:P(X = 13)

= binompdf(14,0.9,13)

The buffer will probably be destroyed by the addition of HCN.

A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.

Given that a 1.0 l buffer solution is 0.15 m in HCN and 0.10 m in NaCN.

We need to find a action which one destroy the buffer solution.

A buffer is a substance made of salt and a weak acid that is beneficial. From the aforementioned chemicals, HCN is a potent acid and NaCN is a salt between HF and NaCN. Therefore, the buffer will probably be destroyed by the addition of HCN.

When presenting chunks of information, bar charts should be used. As long as there aren't too many categories to contrast, vertical bar charts can be useful for comparing several discrete or categorical variables, such as age groups, courses, and schools. For time series data, they are also highly beneficial.

Why would one use a bar chart?

To show a frequency distribution for qualitative data, bar charts are frequently employed.

                   The axis used to measure the bars should always begin at zero, unless there is a valid reason for doing otherwise.

                  Otherwise, the axis can be stretched to magnify differences in the lengths of the bars. A title and the axis labels are required for bar charts.

The set of all rigid motions forms a group under function composition. This means that it satisfies the four group axioms: closure, associativity, the existence of an identity element, and the existence of inverses.

Each rigid motion is a bijection from the Euclidean plane to itself, preserving distances. Function composition of rigid motions results in another rigid motion, demonstrating closure. The associativity of function composition follows from the associativity of composition in general. The identity element is the identity function, which does not alter the position of any point. Finally, the inverse of a rigid motion is another rigid motion that undoes the transformation. Therefore, the set of all rigid motions forms a group.

To prove that the set of all rigid motions forms a group, we need to demonstrate that it satisfies the four group axioms. Firstly, let f and g be two rigid motions. Since rigid motions preserve distances, the composition of f and g will also preserve distances, showing closure.

Secondly, function composition is associative, meaning that (f ∘ g) ∘ h = f ∘ (g ∘ h) for any three rigid motions f, g, and h. This follows from the associativity of composition in general.

Thirdly, the identity element of the group is the identity function, which leaves every point unchanged. Composing any rigid motion with the identity function will result in the same rigid motion, satisfying the identity axiom.

Finally, for every rigid motion f, there exists an inverse rigid motion denoted as f^(-1). This inverse function undoes the transformation performed by f, preserving distances. Composing f with its inverse or the inverse with f will yield the identity function.

Since the set of all rigid motions satisfies all four group axioms, it forms a group under function composition.

To find the simple interest payable, we can use the formula:

Simple Interest = Principal × Rate × Time

where:

Principal = $28,800

Rate = 3.75% per annum (expressed as a decimal, so 3.75% = 0.0375)

Time = 4 years

(a) The simple interest payable is $4,320.

Simple Interest payable:

Simple Interest = $28,800 × 0.0375 × 4

Simple Interest = $4,320

Therefore, the simple interest payable is $4,320.

(b) The monthly repayment amount is approximately $690.

To find the monthly repayment, we need to calculate the total amount to be repaid and then divide it by the number of months in the loan term.

Total amount to be repaid = Principal + Simple Interest

Total amount to be repaid = $28,800 + $4,320

Total amount to be repaid = $33,120

The loan term is 4 years, which is equivalent to 4 × 12 = 48 months.

Monthly repayment = Total amount to be repaid / Number of months

Monthly repayment = $33,120 / 48

Monthly repayment ≈ $690

Therefore, the monthly repayment amount is approximately $690.
