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.

Which equation gives this number of 1/3 inches that are in 5/6 inch
The correct answer is [tex]\frac{5}{6}[/tex] inch.
To find the number of 1/3 inches that are in 5/6 inch, we need to convert both fractions to have a common denominator and then divide the numerators.
[tex]\text{Step 1: Find the LCM of 3 and 6}[/tex]
[tex]\text{LCM}(3, 6) = 6[/tex]
[tex]\text{Step 2: Convert the fractions to equivalent fractions with the denominator of 6}[/tex]
[tex]\frac{1}{3} = \frac{2}{6}[/tex]
[tex]\frac{5}{6} = \frac{5}{6}[/tex]
[tex]\text{Step 3: Divide the numerators of the equivalent fractions}[/tex]
[tex]\frac{5}{6} \div \frac{2}{6} = \frac{5}{2} = 2.5[/tex]
Therefore, there are [tex]2.5[/tex] one-third inches in [tex]\frac{5}{6}[/tex] inch.

Which graph represents the system of equations?
y=2x+1y=2x2+1
Graphing the system involves plotting points for both equations and identifying their intersections. The graph visually illustrates the simultaneous solutions to "y = 2x + 1" and "y = 2x^2 + 1.
Graphing the system of equations "y = 2x + 1" and "y = 2x^2 + 1" involves plotting points that satisfy both equations to identify their intersection. The first equation, "y = 2x + 1," represents a straight line with a slope of 2 and a y-intercept of 1. The second equation, "y = 2x^2 + 1," is a quadratic function, creating a parabolic curve.
To visualize their intersection, plot several points for each equation and observe where they coincide on the graph. For the linear equation, select x-values, calculate the corresponding y-values using the equation, and plot the points. For the quadratic equation, choose various x-values, calculate the corresponding y-values, and plot these points.
The intersection points on the graph represent solutions to both equations. Depending on the specific values chosen, the intersection may occur at one or more points.
The question probable may be:
Graph the following system of equations.
y=2x+1 y=2x^2+1
The two equations intersect at points (0, 1) and (1, 3).
Analyzing the Equations:
Equation 1: y = 2x + 1 represents a linear equation. This means the graph will be a straight line. The slope of the line is 2, and the y-intercept is 1.
Equation 2: y = 2x² + 1 represents a parabolic equation. This means the graph will be a U-shaped curve. Since the coefficient of the x² term (2) is positive, the parabola will open upwards. The y-intercept is also 1.
Identifying the Intersections:
To find the points of intersection, we can set the two equations equal to each other and solve for x:
2x + 1 = 2x² + 1
0 = 2x² - 2x
0 = 2x(x - 1)
The solutions are x = 0 and x = 1. We can then plug these x-values back into either equation to find the corresponding y-values:
y = 2(0) + 1 = 1 (for x = 0)
y = 2(1)² + 1 = 3 (for x = 1)
Therefore, the two equations intersect at points (0, 1) and (1, 3).

Identify the independent and dependent variables.
The equation A=25w gives the area A (in square feet) of a rectangular dance floor with a width of w feet.
The independent variable is
.
The dependent variable is
.
The equation given is: A=25w
This equation gives the area A (in square feet) of a rectangular dance floor with a width of w feet.
As we can clearly see, the area of the rectangular dance floor is dependent on the value of the width,w. As we increase the width, w, the area, A increases and as we decrease, w, A too decreases.
Therefore, the independent variable is "w" and the dependent variable is "A".

Hassan is correct because the point is on the middle of the number line.
Hassan is incorrect because the square root of 15 is less than 0.4

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.
