Answer:

Corresponding angles

Step-by-step explanation:

The name of these angels lying in the same position are called corresponding angle.

These angles are equal. When we talk of parallel lines, they are sets of lines that travel in the same direction but never meet. The third line that cuts through the two sets of parallel lines is referred to as the transversal line.

So the positions of these angles on each of the set of the parallel lines are equal in each of the cases and they are equal and are referred to as being corresponding to each other

The size of the subculture or group under studied determines the sampling size in ethnography. In this regard, it might not be possible to predetermine the participant count. The complete subculture or group being studied serves as the study sample size in anthropological research.

The non-random sample that best resembles stratified random sampling is quota sampling.

Using the non-probability sampling technique of quota sampling, researchers select a sample of people who are typical of the population. These people are chosen by researchers based on specific traits or qualities. In order to use market research samples for data collecting, they decide on and set sample quotas. These samples accurately reflect the entire population. The interviewer's or researcher's knowledge of the population will be the only factor used to select the final subgroup.

Probability sampling means that every member of the population has a chance of being selected.

There are four main types of probability sample.

Simple random sampling.

Systematic sampling.

Stratified sampling.

Cluster sampling.

For instance, a tobacco company would want to know which age group in a given city loves which brand of smokes. The age groups of 21–30, 31–40, 41–50, and 51+ are subject to survey quotas. Based on these findings, the researcher makes an estimation of the smoking trend in the city's inhabitants.

Therefore,

The size of the subculture or group under studied determines the sampling size in ethnography. In this regard, it might not be possible to predetermine the participant count. The complete subculture or group being studied serves as the study sample size in anthropological research.

From images seen online, the first missing proof is Alternate Interior angles because they are formed when a transversal intersects two coplanar lines.

The second missing proof is Transitive property because angles are congruent to the same angle.

The last missing proof is  Converse alternate interior angles theorem

because two lines are intersected by a transversal forming congruent alternate interior angles, then the lines are parallel.

the dimensions of the lot is 100 yards by 400 yards. In this problem, a parking lot has a rectangular area of 40,000 square yards, and the length is 200 yards more than twice the width.

Determining the dimensions of a rectangular area, such as a parking lot, can be a useful task for many purposes, such as planning and designing a new lot or estimating the amount of space available for parking.

Let's call the width of the parking lot "w". Then, the length of the parking lot can be represented as 2w + 200.

The total area of the parking lot is 40,000 square yards, so we can set up an equation to solve for w: w * (2w + 200) = 40,000.

Solving for w, we get w = 100. This means that the width of the parking lot is 100 yards and the length is 2 * 100 + 200 = 400 yards.

The dimensions of the parking lot are 100 yards by 400 yards.

The ordered pairs that are in the domain and range of hog are (-3, (9,-9)) and (7, (-6,3)).

To find the function hog, we need to perform the composition of functions h and g, written as h(g(x)).

First, we need to apply g to its domain, which is {7, 4, -3, 1}.

g(7) = (1,9)
g(4) = (-5,4)
g(-3) = (-6,-3)
g(1) = (9,1)

Now, we can apply h to the range of g.

h((1,9)) = (-6,3)
h((-5,4)) = undefined (since (-5,4) is not in the domain of h)
h((-6,-3)) = (9,-9)
h((9,1)) = undefined (since (9,1) is not in the domain of h)

Thus, the ordered pairs that are in the domain and range of hog are (-3, (9,-9)) and (7, (-6,3)).

Therefore, hog = {(-3, (9,-9)), (7, (-6,3))}.

Corresponding point on a unit circle is equal to \(\boldsymbol{\left [ \frac{-\sqrt{3}}{2},\frac{-1}{2} \right ]}\)

So, option C. is correct.

A unit circle is a circle with radius is equal to one.

Any point on a unit circle is of the form \(\boldsymbol{\left ( cos\, \theta, \sin\, \theta \right )}\)

Value of \(\theta\) is \(\boldsymbol{\frac{7\pi}{6}}\)

So, corresponding point on a unit circle is equal to \(\boldsymbol{\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]}\)

\(\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]=\left [\cos \left (\pi + \frac{\pi}{6} \right ),\sin \left (\pi + \frac{\pi}{6} \right ) \right ]\)

There are 176,851 ways to assign the 100 pages to the four printers.

Since there are no restrictions on how many pages a printer can print, we can think of this problem as distributing 100 identical pages among 4 distinct printers. This is an example of a "balls and urns" problem, which can be solved using the stars and bars formula.

The stars and bars formula states that the number of ways to distribute k identical objects among n distinct containers is:

C(k+n-1, n-1)

where C represents the combination function. In this case, we have k = 100 identical pages and n = 4 distinct printers. Therefore, the number of ways to assign the pages to the printers is:

C(100+4-1, 4-1) = C(103, 3) = 176,851

So there are 176,851 ways to assign the 100 pages to the four printers.

Step-by-step explanation:

The measure of angle 1 is 67.4°. The measure of angle 2 is 104.5°.

An angle is the measure of the amount of rotation between two lines or two planes that meet at a point. It is typically measured in degrees or radians. An angle can be acute, meaning it is less than 90 degrees, right, meaning it is exactly 90 degrees, obtuse, meaning it is greater than 90 degrees but less than 180 degrees, or straight, meaning it is exactly 180 degrees. An angle can also be positive or negative, depending on the direction of rotation between the lines or planes. Angles are used in various fields such as mathematics, engineering, physics, and geometry.

Here,

180-121.8=58.2°

180-(58.2+17.3)=104.5°

180-104.5=75.5°

Answer:

42

Step-by-step explanation:

You have to find the greatest number that divide 294, 252 and 210, i.e., the greatest common factor.

Then, you need to factor each number and calculate the product of the common factors raised to the lowest exponent.

294 = 2*3*7^2

252 = 2^2 * 3^2 * 7

210 = 2*3*5*7

Greatest common factor = 2*3*7 = 42

Answer:

SA = 94 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

SA = 2 ( 47 )

SA = 94 ft²

Step-by-step explanation:

To find the slope we must find the change in y over the change in x. Δ

Or rise over run.  \(\frac{rise}{run}\)

In the graph, we have two "good" points. (0, -6) and (4,0)

So for Δy 0 to -6 = -6

So -6 goes on top  \(\frac{-6}{x}\)

Now Δx goes from 4 to 0 so the change would be -4.

So now it becomes \(\frac{-6}{-4}\)

Since there are two negatives it becomes a positive. \(\frac{6}{4}\) Or simply put, \(\frac{3}{2}\)

The yearly exponential model for the population of bats is C'(t) = 8500 · 1.1ⁿ and the quarterly percentage rate is 2.41 %.

In this question we must determine the exponential model that represents the population of bats, whose model is shown below:

Where:

The yearly exponential model is represented by: (C = 8500, r = 10)

C'(t) = 8500 · 1.1ⁿ

The quarterly rate of change can be found by using the following expression:
