What is parallelogram?
A unique variety of quadrilateral made up of parallel lines is known as a parallelogram. A parallelogram can have any angle between its adjacent sides as long as its opposite sides are parallel. If two opposite sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both pairs of opposite sides are parallel and equal is known as a parallelogram.
We can solve this easily using alternative interior angles. A parallelogram's interior is always 360 degrees, right?
In the given parallelogram the side vy = yx
VY = YX = 80 = 6x+2
6x = 80-2=78
x = 78/6= 13
Hence The measured value x = 13.

Which of the following comparisons is TRUE?
Attention Grabbers Bookstore Budget
Advertising 1/6
Rent 7/12
Supplies 1/4
A] The bookstore spends more on advertising than rent.
b} The bookstore spends more on supplies than advertising.
c}The bookstore spends more on advertising than supplies.
d]The bookstore spends more on supplies than rent.
Answers
==========================================================
Explanation:
Let's go through each answer choice to see which are true and which are false.
A.
The fractions for advertising and rent are 1/6 and 7/12 respectively. The LCD is 12, so let's get 1/6 to have a denominator of 12. Multiply top and bottom by 2 to get 1/6 = 2/12.
Now we can compare the fractions 2/12 (aka 1/6) and 7/12. Clearly 7/12 is larger. It's like saying "having 7 slices of pizza is more than 2 slices of pizza". Therefore, the claim that more was spent on advertising compared to rent is false.
----------------------
B.
1/4 = 3/12 when multiplying top and bottom by 3
3/12 was spent on supplies and 2/12 was spent on advertising
We see that more was spent on supplies, so claim B is true
----------------------
C.
This claim is false because it contradicts claim B.
Another way to see why it's false is to use a calculator to get these decimal values
advertising = 1/6 = 0.17 approximatelysupplies = 1/4 = 0.25 exactlySince 0.17 is not larger than 0.25, this means 1/6 is not larger than 1/4.
----------------------
D.
We could use any of the methods mentioned in the previous sections, but I'll go another route.
For now assume that the fractions for supplies and rent (1/4 and 7/12 respectively) are equal.
Let's use cross multiplication to say the following:
1/4 = 7/12
1*12 = 4*7
12 = 28
Clearly the two sides are different so the original fractions aren't equal. To fix this error, replace each equal sign with a "less than" sign like so
1/4 < 7/12
1*12 < 4*7
12 < 28
Think of it like working backward up the chain. Start with 12 < 28 which is clearly true, and you can work backwards to end up with 1/4 < 7/12.
The fact we end up with 1/4 < 7/12 shows the claim "The bookstore spends more on supplies than rent" is false. It's the other way around: the bookstore spent more on rent compared to supplies.
----------------------

What do you mean by SRS (Simple Random Sample)?Simple Random Sample (SRS) is a statistical technique for selecting a sample from a population, where each individual or item in the population has an equal chance of being selected for the sample. In other words, a simple random sample is a representative subset of a population where every individual or item in the population has an equal chance of being selected for the sample.
To take a simple random sample, each individual in the population is assigned a unique number, and then random numbers are generated to select the required number of individuals for the sample. This method ensures that the sample is not biased towards any particular subset of the population, and that the sample is representative of the whole population.

Answers
(x - 10)² = -12 (y + 4) represents a parabola with a vertical axis of symmetry, vertex at (10, –4), and p = –3 .
What's a vertical parabola?
A vertical parabola has its axis of symmetry at x = h, and the vertex is (h, v). With this information, you can find the focus and directrix. The focus is the distance from the vertex to the focus is 1/(4a), where a can be found in the equation of the parabola (it is the scalar in front of the parentheses).
we know that
If the axis of symmetry is parallel to the y-axis, then we have a vertical parabola
The equation of a vertical parabola is equal to
4p(y - k) = (x - h)²
where
(h,k) is the vertex
In this problem we have
(h,k) = (10, –4)
p= -3
substitute

What do you mean by Domain?In mathematics, the domain of a function is the set of all possible input values (independent variable) for which the function is defined. In other words, the domain is the set of values that we can substitute for the independent variable in a function to produce a meaningful output.
For example, consider the function f(x) = 2x. Here, we can substitute any real number for x and get a meaningful output. Therefore, the domain of this function is all real numbers, or (-∞, ∞). However, if we consider the function g(x) = 1/x, we can see that we cannot substitute 0 for x because division by 0 is undefined. Therefore, the domain of this function is all real numbers except 0, or (-∞, 0) U (0, ∞).
The domain of a relation is the set of all possible values for the independent variable (x) for which there exists a corresponding value of the dependent variable (y). In this case, the given coordinates are (1,3), (4,1), and (-5,-4).
The domain of the relation would be the set of x-values that correspond to the given coordinates. So, the domain of this relation is {-5, 1, 4}.

What are Asymptotes?An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required
There are 3 types of asymptotes
Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero
Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero
Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b
Given data ,
Let the function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = ( -4x² + 36 ) / ( x + 3 )
On simplifying , we get
g ( x ) = -4 ( x² - 9 ) / ( x + 3 )
On further simplification , we get
g ( x ) = -4 ( x + 3 ) ( x - 3 ) / ( x + 3 )
g ( x ) = -4 ( x - 3 )

In a large group of students who completed STA 2023, 20% earned an A in the course, 12% didn’t bring their phone to class and 85% of those who didn’t bring their phone to class earned an A
Answers
It is given that:
20% of the students earned an A in STA 2023.
12% of the students didn't bring their phones to class.
85% of the students who didn't bring their phones to class earned an A.
To answer the following questions, we assume whether all students took STA 2023 and brought their phones to class or not.
a) Let's assume that x% of the students earned an A and brought their phones to class. Then, since the remaining (100% - 12%) = 88% of students brought their phone to class but their grade is not specified, we can set up the following equation:
x% + 85% of 12% = 20%
x% + 0.102 = 0.20
x% = 0.098
Therefore, 9.8% of students earned an A and brought their phones to class.
b) Let's assume that y% of the students didn't earn an A and didn't bring their phones to class. Then, we can set up the following system of equations:
x% + y% = 100% - 12%
0.85*(12%) = y%
Solving for y, we get:
y% = 9.6%
Therefore, 9.6% of students didn't earn an A and didn't bring their phones to class.

What is dilation?Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image. Resizing an object is accomplished through the transformation of dilation. The objects can be enlarged or shrunk using dilation. The result of this transformation is an image that has the same shape as the original shape. The size of the shape varies, though. A dilation should either stretch or contract the original shape. The term "scale factor" describes this transformation.

For this problem, the option D gives the irrational number, as it is the lone non-repeating decimal. For the others, we have that:
Option A: 26 is the repeating decimal part.Option B: 3 is the repeating decimal part.Option C: due to the large number of zeros, the number is the exact decimal 2.8.More can be learned about rational and irrational numbers at brainly.com/question/5186493

How to put anything from least to greatest?
The decimals that you have put are the following:
2.16
2.1682
2.2
2.016
How to do it:
If you look at the decimals the last one, 2.016 does not have a 1 or a 2 instead it has a 0 so that would be a our first decimal in the least to greatest form.
We can also include the third one 2.2 is the only one that has a 2 so now we know that 2.2 will go last.
Lets compare the first and second ones which are 2.16 and 2.1682 and I think we obviously know that the answer is 2.1682 because it is greater then 2.16.
So now here are the decimals from least to greatest:
2.016, 2.16, 2.1682, 2.2
