Answer:

x = 7

Step-by-step explanation:

The 2 angles are Alternate exterior angles and are congruent, so

2x - 3 = x + 4 ( subtract x from both sides )

x - 3 = 4 ( add 3 to both sides )

x = 7

For the lines to be parallel, then x = 7

Step-by-step explanation:

we have the basic ratio between liters of petrol (gasoline) and distance driven :

19/50

now, the same ratio has to apply, when we talk about 130 km instead of just 50.

so,

19/50 = x/130

x = 130×19/50 = 13×19/5 = 49.4 liters

The standard deviation lies in the range of 0 to 1. The numerical value of standard deviation can never be negative.

The standard deviation is a measure of amount of variation or dispersion of a set of values. When we compare two unequal observations, the result is always greater than zero i.e., always positive.

Standard deviation is the square root of the variance of the observations and the root always gives values either positive or zero, it can never be negative.

Therefore, the numerical value of the standard deviation can be positive. The value of standard deviation is always greater or equal to zero.

the minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is 384.12, which can be rounded up to 385.

The minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is as follows:

95% confidence, within 5 percentage points, and a previous estimate of 0.25.

The formula to calculate the sample size required for the study to determine the proportion is given by:

`n = Z²pq / E²`

Where n = sample size

Z = z-value (1.96 at 95% confidence interval)

E = margin of error

p = estimated proportion of the population

q = 1 - pp

q = estimated proportion of population without the condition (1 - 0.25 = 0.75)

Given,

Z = 1.96E = 0.05p = 0.25q = 0.75

Substituting these values in the above formula, we get;

`n = (1.96)²(0.25)(0.75) / (0.05)²``n = 384.16`

Therefore, the minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is 384.12, which can be rounded up to 385.

Answer:

Answer:

Step-by-step explanation:

To start calculating, we first need to make some proof.

Firstly, since AB = AC, we know that ΔABC is isosceles, which means that ∠ABC = ∠ACB.

Now, looking only to ΔBDE and ΔCDF, we can see that they are similar, because the two of its angles are congruent:

∠BED=∠CFD

∠DBE=∠DCF

To make it easier to visualize which are the corresponding vertexes, we can draw them like this:

And we need to remember that BC is 24, so:

BD+CD=24

Since the triangles are similar, their corresponding sides have constant ratio, which we can calculate from the corresponding sides DE and CF:

\(r=\frac{CF}{DE} =\frac{7.5}{4.5} =\frac{5}{3} \)

This ratio is the same for the other corresponding sides, so we can apply that for BD and CD:

\(r=\frac{CD}{BD} =\frac{5}{3}\\ \frac{BD}{CD}=\frac{3}{5} \\\\ BD=\frac{3}{5} Cd\)

Thus, the measure of CF is approximately 13, alternative D.

Answer:

The area is 27m.

Step-by-step explanation:

We can first seperate this shape into two shapes. I seperated the 3x6 rectangle and the 3x3 square. Now we can find the area of these individual shapes. 3x3=9 and 3x6=18. We can now add these two numbers together to get the area of this shape. 9+18=27m. Therefore, the area of this shape is 27m.

If a prism's base is a regular \(n\)-gon, then the prism has 2 regular \(n\)-gon faces, n squares, 3n edges, and 2n vertices. This is because a prism has a top face, a bottom face, and n square faces.

1. If a prism's base is a regular \(n\)-gon, then it has \(n\) vertices on the base.

2. If the base has n vertices, then there will be n edges connecting those vertices.

3. The prism has two regular n-gon faces and n square faces. Therefore, it has 2n vertices and 3n edges.

4. A prism with base a regular n-gon has 2n + n = 3n faces, where 2n are the bases and n are the square faces. Therefore, it has n square faces.

If a prism has a regular polygon as its base with n sides, it will have n vertices, n edges, and n squares. A prism is a solid object that has a top face, a bottom face, and other flat faces that are usually parallelograms or rectangles.

The base is the shape that is repeated in the prism, and it can be any polygon. In this case, we're talking about a regular polygon, which is a polygon with all sides and angles equal in measure.

A regular polygon with n sides has n vertices. Therefore, a prism with a regular n-gon base has n vertices. The number of edges in a prism is found by counting the edges on the base and the edges that connect the corresponding vertices of the base.

So, a prism with a regular n-gon base has n edges on the base and n more edges that connect the corresponding vertices of the base, giving a total of 2n edges.The number of faces in a prism is the sum of the top and bottom faces and the number of lateral faces.

A prism with a regular n-gon base has two n-gon faces and n square faces. Therefore, the total number of faces is 2n + n = 3n faces.

Thus, we have that if a prism's base is a regular n-gon, then the prism has 2 regular n-gon faces, n squares, 3n edges, and 2n vertices.

The distribution that the residuals in our model to follow is equals to the normal probability distribution. So, option(a).

Because residuals are defined as the difference between any data point and the regression line, they are sometimes called "errors". An error in this context does not mean that there is anything wrong with the analysis. In other words, the residual is the error that is not described by the regression line. The residue(s) can also be expressed by "e". The formula is written as, Residual = Observed value – predicted value or

\(e = y – \hat y \).

In order to draw valid conclusions from your regression, the regression residuals should follow a normal distribution. The residuals are simply the error terms or differences between the observed value of the dependent variable and the predicted value. Therefore, the residuals should have a normal distribution.

The Cartesian coordinate system is also referred to as a plane because it represents a two-dimensional space.

In mathematics, a plane is a flat surface that extends infinitely in all directions. The Cartesian coordinate system consists of two perpendicular lines, known as the x-axis and y-axis, which intersect at a point called the origin. These axes divide the plane into four quadrants.

The term "plane" in the context of the Cartesian coordinate system originates from the concept of a geometric plane, which is a fundamental concept in Euclidean geometry. In Euclidean geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions.

The Cartesian coordinate system borrows this concept and applies it to represent points, lines, curves, and shapes in a two-dimensional space.

By using the Cartesian coordinate system, we can assign coordinates (x, y) to any point in the plane, where the x-coordinate represents the horizontal position and the y-coordinate represents the vertical position.

This system allows us to precisely locate and describe objects or phenomena within the two-dimensional space, making it a valuable tool in various fields such as mathematics, physics, engineering, and computer graphics.

By  null hypothesis the given statement " in a two-sided test for mean, we do not reject if the parameter is included in the confidence interval."is True.

In a two-sided test for mean, if the null hypothesis is that the population mean is equal to some value μ0, then the alternative hypothesis is that the population mean is not equal to μ0.

If we compute a confidence interval for the population mean using a certain level of confidence (e.g. 95%), and the confidence interval includes the null value μ0, then we fail to reject the null hypothesis at that level of confidence.

This is because the confidence interval represents a range of plausible values for the population mean, and if the null value is included in that range, we cannot say that the data provides evidence against the null hypothesis.

However, if the confidence interval does not include the null value μ0, then we can reject the null hypothesis at that level of confidence and conclude that the data provides evidence in favor of the alternative hypothesis that the population mean is different from μ0.

The exterior angle of each polygon and the adjacent interior angle are

supplementary.

(a) 72°    (b) \(\displaystyle 51 \frac{3}{7} ^{\circ}\)    (c) 36°    (d) 20°    (e) 18°

Reasons:

The formula for the exterior angle of a regular polygon is, \(\displaystyle \theta = \mathbf{ \frac{360 ^{\circ}}{n}}\)

Where;

θ = The exterior angle of the polygon

n = The number of sides of the regular polygon

(a) The number of sides in a pentagon, n = 5 sides

Therefore, for a regular pentagon, we have;

\(Exterior \ angle , \displaystyle \theta = \frac{360 ^{\circ}}{5} = \mathbf{{72^{\circ}}}\)

The measure of the exterior angle of a pentagon, is 72°

(b) An heptagon has n = 7 sides

The measure of the exterior angle, θ, of a regular heptagon is therefore;

\(Exterior \ angle \ of \ a \ heptagon , \,\displaystyle \theta = \frac{360 ^{\circ}}{7} = \underline{51 \frac{3}{7} ^{\circ}}\)

(c) A decagon has n = 10 sides, which gives;

\(The \ exterior \ angle \ of \ a \regular \ decagon, \,\displaystyle \theta = \frac{360 ^{\circ}}{10} = \underline{36^{\circ}}\)

(d) The exterior angle of an 18-gon with n = 18 sides is given as follows;

\(The \ exterior \ angle \ of \ a \ regular \ 18-gon, \,\displaystyle \theta = \frac{360 ^{\circ}}{18} = \underline{20^{\circ}}\)

Master Theorem Version 2 subsumes Master Theorem Version 1, making the latter redundant and unnecessary.

Master Theorem Version 2, on the other hand, has only three cases, but these are designed to cover all possible scenarios.

There is no need for an extra answer case, as the theorem covers all possible growth rates of the subproblems and the combining factor.

This makes Master Theorem Version 1 redundant, as it has a gap that needs to be filled with additional analysis, while Master Theorem Version 2 covers all cases.

In terms of how the remaining answer cases align, both versions of the theorem have the same answer for the cases they share.

The difference is that Master Theorem Version 2 includes additional cases that were not covered by Version 1.

This means that Master Theorem Version 2 is a more comprehensive and complete tool for analyzing the time complexity of recursive algorithms.
