Commutative property

commutative if changing the order of the operands does not change the result.

To determine if a given graph is the reciprocal function of y = (x + 3)%, we can examine its characteristics and compare them to the properties of the reciprocal function. Similarly, to sketch the graph of y = 3 sin(x + n)-1, we can use key points to identify the shape and behavior of the function.

For the given function y = (x + 3)%, we can determine if it is the reciprocal function by analyzing its behavior.

The reciprocal function has the form y = 1/f(x), where f(x) is the original function. In this case, the original function is (x + 3)%.

If the given graph exhibits the properties of the reciprocal function, such as asymptotes, symmetry, and behavior around x = 0, then it can be considered the reciprocal function.

However, without a specific graph or further information, we cannot conclusively determine if it is the reciprocal function.

To sketch the graph of y = 3 sin(x + n)-1, we can start by choosing key points and plotting them on a coordinate plane. The graph of a sine function has a periodic wave-like shape, oscillating between -1 and 1. The amplitude of the function is 3, which determines the vertical stretching or compression of the graph.

The parameter n represents the phase shift, shifting the graph horizontally.

To create a mapping table, we can select values of x within the given interval -2n ≤ x ≤ 2n and evaluate the corresponding y-values using the equation y = 3 sin(x + n)-1.

For example, we can choose x = -2n, x = 0, and x = 2n as key points and calculate the corresponding y-values using the given equation. By plotting these points on the graph, we can get an idea of the shape and behavior of the function within the specified interval.

The sum of the exterior angles for ALL polygons is 360 degs.

360/32 = 11.25�

This question is based on the concept of exterior angles polygon. Therefore, the measure of an exterior angle of a regular polygon with 32 sides that is 32- gon is 11.25 degree.

In this question we need to determined the exterior angles of the 32- gon.

A polygon which has 32 sides is called 32- gon.

By using the formula of the exterior angle we have to calculate this.

As we know that,

The sum of exterior angles in a polygon is always equal to 360 degrees.

Now calculate the exterior angle of an regular polygon with 32 sides that is 32- gon. Therefore,

\(=\dfrac{360}{32}\)

Now, solve it further, we get,

= 11.25 degree

Therefore, the measure of an exterior angle of a regular polygon with 32 sides that is 32- gon is 11.25 degree.

Therefore, the 95% confidence interval for the population proportion of disks that are defective is (0.8357, 0.9475). This means that there is a 95% probability that the true population proportion of disks that are defective is between 0.8357 and 0.9475.

The quality-conscious disk manufacturer can use a 95% confidence interval to estimate the fraction of defective disks made by the company. The 95% confidence interval is calculated using the sample data to construct an interval estimate of the population proportion.
Using the given data, the sample proportion of disks that are not defective is 904/1015 = 0.8915.
The 95% confidence interval for the population proportion of disks that are defective is then given by:
Lower limit = 0.8915 – (1.96 x √(0.8915 x (1- 0.8915)/1015))
= 0.8915 – (1.96 x 0.0285)
= 0.8915 – 0.0558
= 0.8357
Upper limit = 0.8915 + (1.96 x √(0.8915 x (1- 0.8915)/1015))
= 0.8915 + (1.96 x 0.0285)
= 0.8915 + 0.0558
= 0.9475

Among the three options provided, the cross-sectional data set is the demographic data. Correct option is B).

Cross-sectional data refers to a type of data that captures information about different individuals, entities, or units at a specific point in time. It provides a snapshot of a population or sample at a particular moment, allowing for comparisons and analysis of various characteristics or variables. In the case of demographic data, it typically includes information about individuals' age, gender, education level, income, and other demographic attributes. This data set does not capture changes or trends over time but rather provides a snapshot of the population's characteristics at a specific time.

On the other hand, the BCAD data and links could refer to data related to building codes, regulations, and their corresponding references, while code cases may refer to specific instances or examples of code violations or compliance. These data sets may be specific to certain incidents or cases and do not necessarily capture information about a population or sample at a particular point in time, making them less likely to be considered cross-sectional data.

Step-by-step explanation:

a) Using the Euclidean algorithm, we can find gcd (707,413) as follows:707 = 1 · 413 + 294413 = 1 · 294 + 119294 = 2 · 119 + 562119 = 2 · 56 + 71356 = 4 · 71 + 12 71 = 5 · 12 + 11 12 = 1 · 11 + 1

Thus, gcd (707,413) = 1.

We can find the coefficients s and t that solve the equation 707s + 413t

= 1 as follows:1 = 12 - 11 = 12 - (71 - 5 · 12) = 6 · 12 - 71 = 6 · (119 - 2 · 56) - 71

= - 12 · 56 + 6 · 119 - 71

= - 12 · 56 + 6 · (294 - 2 · 119) - 71 = 18 · 119 - 12 · 294 - 71

= 18 · 119 - 12 · (413 - 294) - 71 = 30 · 119 - 12 · 413 - 71

= 30 · (707 - 1 · 413) - 12 · 413 - 71 = 30 · 707 - 42 · 413 - 71

Thus, s = 30, t = -42. So we have found that 707(30) + 413(−42) = 1.

b) Since 707s + 413t = 1 and 9 does not divide 1, the equation 707x + 413y = 9 has no integer solutions. Therefore, we can conclude that there are no such integers x and y.

\(angle \: 2 \: = angle \: 5\)

\(3x - 20 = x + 20\)

Add sides 20

\(3x - 20 + 20 = x + 20 + 20\)

\(3x = x + 40\)

Subtract sides x

\( - x + 3x = - x + x + 40\)

\(2x = 40\)

Divide sides by 2

In the image, we can identify the region of the plane in which the two subregions overlap (the part of the graph which has vertical and horizontal lines). We can obtain the values of x and y in that region by means of the inequalities, in this way:

We solve the first inequality for y

This gives us the first constrain for the value of y

Now, to obtain the second constrain we simply need to use the second inequality:

Finally, the last step is to get the constraints for the value of x.

For this, we can directly analyze the image of the region, notice how it covers any value of x. This means that there are no constraints for the value of x.

So, the region is given by:

Finally, the point that is in the region is the one that satisfies the previous inequalities.

1. (2,0)

If x=2, then

So, (2,0) cannot be the correct option

2. (0,2)

This means that (0,2) cannot be the right option

3. (0,3) notice that the same condition (y>2) holds in this situation too (since x=0)

But y=3>2. This point indeed satisfies the conditions! (0,3) is the answer

4. (0,-1) Notice that in this case y=-1 but it should happen that y>2. So this point cannot be in the region
