Answers
The polling methods likely to be biased are when Option d. Five of Janine's friends are selected and asked for whom they intend to vote.
When conducting a poll, it is important to ensure the sampling method is random and representative. Here are the methods and their potential biases:
Janine chooses 5 members that plan on voting for her and asks each to select another 5 members. These 25 members are asked for whom they intend to vote. — This method is likely to be biased because it relies on the initial selection of supporters, which creates a non-random and unrepresentative sample.Every 10th club member from a list of all members is selected and asked for whom the member intends to vote. — This method is less likely to be biased as it uses systematic sampling, which is more representative of the entire population.From a list of all club members, 25 members are selected at random and asked for whom they intend to vote. — This method is unlikely to be biased because it employs a simple random sample, ensuring each member has an equal chance of being selected.Five of Janine's friends are selected and asked for whom they intend to vote. — This method is likely to be biased due to the convenience sampling of her friends, which is not representative of the entire club.Hence option D is likely to be biased.

What is a decimal in tenths that is less than 2.42 but greater than2.0
Answers
If 5a=-4b+5 and 3a=-2b+3, what is 6b?
Answers
5a = -4b + 5
3a = -2b + 3
You can multiply the second equation by two, so the 4b and -4b in both equations will cancel each other out when you add them. So:
5a = -4b +5
6a = 4b +6
Add both equations together.
11a = 11
a = 1
Plug in the a value into any of the previous equations:
5(1) = -4b + 5
-4b = 0
b = 0
So, since we know that b = 0, 6b is also 0.

The living room in stacy's house is 18 feet by 12 feet and has wall-to-wall carpeting. Hiw many square inches of carpeting will Tom need for thevliving room in Stacy's doll house?
Answers
To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft.
Explanation:To find the area of the living room in Stacy's doll house, we need to use the given scale of 2 inches:3ft. First, we convert the dimensions of the living room from feet to inches. The dimensions of the living room in inches will be 18 feet * 12 inches/foot = 216 inches by 12 feet * 12 inches/foot = 144 inches.
Next, we multiply the dimensions by the scale factor of 2 inches:3ft. The dimensions of the living room in the doll house will be 216 inches * (2 inches/3ft) = 144 inches and 144 inches * (2 inches/3ft) = 96 inches.
Finally, we multiply the dimensions together to find the area: 144 inches * 96 inches = 13,824 square inches.

The triangle inequality theorem states that any two sides of a triangle must have a sum greater than the third side. Given the two sides we have, 7 and 4, the sum would be 11; this would mean that the missing side could be no more than 10.
If we take the unknown side and the smallest one we're given, we would have the inequality
n+4>7
Subtracting 4 from both sides we would have n>3. That means it would have to be the next integer up, which would be 4.

What series of transformations to quadrilateral ABCD map the quadrilateral onto quadrilateral EFGH to prove that ABCD≅EFGH ?
a reflection across x-axis, and then a translation 4 units left
a reflection across x-axis, and then a translation 4 units right
a reflection across y-axis, and then a translation 4 units right
a reflection across y-axis, and then a translation 4 units left
Answers
Comparing the points to their mapped images compares A to E, B to F, C to G, and D to H. In each point, the y-coordinate switches signs and the x-coordinate is subtracted by 4.
Reflections across the x-axis will switch the sign of the y-coordinate, and reflections across the y-axis will switch the sign of the x-coordinate. Since the y-coordinates are the ones whose sign changed, the points must have been reflected across the x-axis.
Translations to the left will cause the x-coordinate to increase, and translations to the right will case the x-coordinate to decrease. Since the x-coordinate of every point was subtracted, this means that the translation must have been to the right.
The correct series of transformations is a reflection across the x-axis, and then a translation 4 units left.
Let's start by labeling the vertices of quadrilateral ABCD as follows:
A(2, 4)
B(4, 5)
C(5, 4)
D(4, 1)
If we reflect quadrilateral ABCD across the x-axis, the new coordinates of the vertices will be:
A'(2, -4)
B'(4, -5)
C'(5, -4)
D'(4, -1)
Now, if we translate quadrilateral A'B'C'D' 4 units left, the new coordinates of the vertices will be:
E(-2, -4)
F(0, -5)
G(1, -4)
H(0, -1)
These are the coordinates of the vertices of quadrilateral EFGH.
Therefore, it can prove that for the transformation to quadrilaterals ABCD≅EFGH by reflecting quadrilateral ABCD across the x-axis and then translating it 4 units left.

Option (C) is correct.
The solutions of the graph showing a system consisting of a linear equation and a quadratic equation are (1,8) and (4,5).
Step-by-step explanation:
Given : The graph showing a system consisting of a linear equation and a quadratic equation.
We have to find the solution(s) to the system.
Since , the solution(s) to the system are the points where the both linear equation and a quadratic equation intersect each other.
So from the graph given the linear equation intersect the quadratic equation at two points namely (1,8) and (4,5).
Thus, the solutions of the graph showing a system consisting of a linear equation and a quadratic equation are (1,8) and (4,5).

1: What square root best approximates the point on the graph?
Well, here you are shown a number line. On the number line, there is a point. Guesstimating it shows it's around 5.1-5.2. It is definitely lower than 5.5, as that would be directly in the middle of 5 and 6.
Well, the answer are:
A square root of 5
A square root of 15
A square root of 28
A square root of 53
Well, this question is a little unclear to me. I am considering if the question is stating that those numbers, 5, 15, 28, and 53 are ALREADY the sqaure root of a number, or if those 4 numbers are what you are supposed to find out which square root lines up to the point on the chart.
Because it seems that none of these four numbers would work with my first theory, I'll go with the simpler of the two, the latter. Meaning those four numbers are the numbers that you have to find the square root of, and the correct one should line up with the chart.
SO, pull out your calculator kiddo. You don't want to have to calculate square root by hand, you'll run out of paper/and or pencils before you know it. It usually takes a bit of time for each one, and considering you have multiple one's to calculate. . . Yeah, go with the calculator.
So, plug in each of the numbers into a TI-84 or basically any calculator that works with square root calculations.
Square root of 5: 2.2360679775
Square root of 15: 3.87298334621
Square root of 28: 5.29150262213
Square root of 53: 7.28010988928
Alright. Well, what do we know? From our guesstimation, the point looked to be close to 5.2
None of these match that EXCEPT C: 28
Your best shot for #1 is 28
2. Hassan used the iterative process to locate the square root of 15 on the number line.
I'll be frank: I've never heard of the "iterative process" in my life, and if I have, i definitely can't recall. This is most likely a different term used for some other process that I probably DO know, but anyways, that's not quite relevant, so I'll carry on:
Looking at the graph we see H-man graphed his point on the number line at EXACTLY .45
We know this because the dot is directly in the middle of .4 and .5, and .45 is the best way to represent that (imagine .4 is .40, and .5 is .50 if this helps, the value is ultimately the same)
Now, H-man graphed this point specifically because he used his "process" to find the square root of 15.
Once again, I'm not sure what this process is, but I'll help to the best of my ability. The square root of 15 is around 3.9
I'm assuming H-man's process simply moved around the decimal place, somehow. This I am not sure on, but it's the only thing that makes somewhat sense to me.
So, if this is correct, on his terms, the graphed point should be more like: 0.39
Now, his point is considerably further than this. This would mean (don't quote me on this) that Hassan is incorrect, and I would say this because the sqare root of 15 is less than .4
Yes, this doesn't make much sense to me, but if I'm correct, then this answer should also be correct. Relatively.
3. The point plotted on the number line is the square root of x.
What is the approximate value of x?
Basically X represents the original number, and the numbers they give you are what they want you to choose the original number is. This is based on the point on the graph, which is at around 4.1, because this number is the square root of X.
To solve this, find the square roots of all 4 numbers (separately of course).
The square root of 4 is: 2
The square root of 9 is: 3
The square root of 17 is: 4.12310562562
The square root of 20 is: 4.472135955
Now, from our guess we can clearly see the point is around 4.1
The answer that nearly matches this estimate EXACTLY is C: 17
Your choice here is 17
Total:
#1=28
#2=Hassan is incorrect because the square root of 15 is less than 0.4 (guess)
#3=17
The square root which is best approximated by the point on the graph is given by: Option C: A square root of 28. Also, the square root of 15 lies between 3 and 4.
How to find the closest integer less than and greater than the square root of a number?The function [tex]y = \sqrt{x}[/tex] is strictly increasing function for x ≥ 0.
Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too.
That means, we've got:
[tex]x_1 < x_2 < x_3 \implies \sqrt{x_1} < \sqrt{x_2} < \sqrt{x_3} \: \text{(such that } x_1 \leq 1)[/tex]
Perfect square are those integers whose square root is an integer.
Let x-a be the closest perfect square less than x,
and let x+b be the closest perfect square more than x, then we get:
x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).
Then, we get:
[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]
Thus, [tex]\sqrt{x-a}[/tex] and [tex]\sqrt{x+b}[/tex] are the closest integers, less than and more than the value of [tex]\sqrt{x}[/tex]. (assuming x is non-negative value).
Now, from the first graph, we see that the value of the square root is between 5 and 6, therefore, we have:
[tex]5 < \sqrt{x} < 6[/tex]
Now, squaring all the sides, we get:
[tex]25 < x < 36[/tex]
Thus, the number out of the given options, whose square root lies between 5 and 6 is given by: Option C: A square root of 28
It is because 25 < 28 < 36, and no other option satisfies this,
For square root of 15, the perfect squares closest to 15 are 9 and 16, therefore, we get:
[tex]\sqrt{9} < \sqrt{15} < \sqrt{16}\\\\3 < \sqrt{15} < 4[/tex]
Thus, the square root which is best approximated by the point on the graph is given by: Option C: A square root of 28. Also, the square root of 15 lies between 3 and 4.

Answers
So the right answers are 4 and 5.
Let's explain each case.
First. A prism and a horizontal plane
The representation of this statement is shown in Figure 1. A prism has the following characteristics:
1. These objects have identical ends.
2. They have flat faces.
3. They have the same cross section all along its length
So in the figure, you can see how the horizontal plane intersects the prism. The cross section of this object is a triangle. Thus, it has the same cross section all along its length and this object is called a triangular prism.
Second. A vertical plane and a pyramid
As shown in Figure 2 you can see the representation of this statement. If the pyramid is cut with a plane that passes through the top vertex and it is perpendicular to the base, then the intersection of this pyramid and the plane becomes a triangular cross section.
The geometric figures that intersect to form a cross-section are:
4. a prism and a horizontal plane 5. a vertical plane and a pyramidFor a cross-section to be formed, then the intersected figures must be a plane and a three-dimensional object.
From the list of given options, option (1) through (3) cannot be true;
This is so because: lines and points are not three-dimensional or planes
However, in options (4) and (5);
Vertical planes, horizontal planes and prism are planes or three-dimensional object.
