Median :
The value that separates the upper half of a population, a data sample, or a probability distribution from the lower half is known as the median. It could be referred to as "the middle" value for a data set. The value in the middle of a data set is called the median. This means that 50% of the data points have values that are smaller than or equal to the median, and 50% of the data points have values that are higher than or equal to the median. First, you count the number of data points (n) and arrange them in ascending order for a small data set.
How is the Median Calculated?The middle value in a set of data is called the median. First, arrange the data in ascending order from smallest to largest. Divide the total number of observations by two to get the midpoint value. Round that number up if there are an odd number of observations, and the value in that position is the median. Take the average of the values found above and below that position if the number of observations is even.

at a local veterinary office, 48% of dogs get their teeth cleaned, while 35% of cats get their teeth cleaned. let p hat subscript upper d and p hat subscript upper c be the sample proportions of dogs and cats at this veterinary office, respectively, who get their teeth cleaned. suppose 25 dogs and 32 cats from this veterinary office are selected at random to collect data on their teeth-cleaning history. which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat subscript upper d baseline minus p hat subscript c ?
The difference (Dogs – Cats) in the sample proportions of those that get their teeth cleaned typically varies about 0.054 from the true difference in proportions.
The third option is correct.
What is the standard deviation?
Standard deviation is a statistical measure of the spread of a dataset, defined as the square root of its variance. It is a way to quantify the amount of variation or dispersion of a set of data values.
Percentage of Dogs getting their teeth cleaned = 48% = pD
Percentage of Cats getting their teeth cleaned = 35% = pC
Number of Dogs selected = nD = 25
Number of Cats selected = nc = 32
As the sample sizes are large enough, we can apply Central Limit Theorem
According to Central Limit Theorem for proportions –
pD-hat ~ Normal(pD, {pD*(1-pD)}/nD)
Thus, pD-hat ~ Normal(0.48, 0.009984)
Similarly,
pC-hat ~ Normal(pC, {pC*(1-pC)}/nC)
Thus, pC-hat ~ Normal(0.35, 0.0071094)
Now if X ~ N(E(X), Var(X)) and Y ~ N(E(Y), Var(Y))
then X -Y ~ N(E(X)-E(Y), Var(X)-Var(Y)) (If X and Y are Independent)
Thus,
pD-hat - pC-hat ~ Normal(0.48-0.35, 0.009984 – 0.0071094)
pD-hat - pC-hat ~ Normal(0.13, 0.0028746)
Thus, Standard Deviation of pD-hat - pC-hat = (0.0028746^0.5) = 0.0536 that is 0.054 approximately
Hence, the difference (Dogs – Cats) in the sample proportions of those that get their teeth cleaned typically varies about 0.054 from the true difference in proportions.

The polynomial[tex]1-x x^2-x^3 \ x^{16}-x^{17}[/tex] can be written in the form [tex]a0 + a1(x+1) + a2(x+1)^2 + ... + a16(x+1)^{16} + a17(x+1)^{17}[/tex] where y = x + 1 and a1's are constants.
a polynomial can be written in the form
[tex]a0 + a1x + a2x^2 + a3x^3 + ... + anx^n[/tex]
where a0, a1, a2, ..., an are constants (also known as coefficients) and x is the variable.
In this case, we are given a polynomial in the form [tex]1-x x^2-x^3 \ x^{16}-x^{17}[/tex] and we want to express it in the form [tex]a0 + a1y + a2y^2 + ... + a17y^{17}[/tex], where y = x + 1 and a1's are constants.
By substituting y = x + 1 into the polynomial, we get:
[tex]1 - (x + 1) + (x + 1)^2 - (x + 1)^3 + ... + (x + 1)^{16} - (x + 1)^{17}[/tex]
Each term in this polynomial is a function of y, which is in turn a function of x.
We can then match the coefficients a0, a1, a2, ..., a17 with the corresponding powers of y in the polynomial, i.e, a0 = 1, a1 = -1, a2 = -1, a3 = 0, ..., a16 = -1, a17 = -1, and we get the polynomial

What are triangles?
Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.
A triangle is categorized into three categories based on its sides, namely:
Scalene Triangle - Each side has a distinct length.
Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.
Equilateral Triangle - A triangle has three sides that are of the same length.
A triangle is categorized into three categories based on its angles, namely:
Acute Angle Triangle - A triangle with all of its angles smaller than 90°.
Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.
Triangle with a Right Angle - A triangle with one of its angles equal to 90°.
Now,
As shown in image that the angles ∠BAD and ∠ADC are alternate angles, and therefore equal. Likewise, angles ∠ABC and BCD are also alternate and therefore equal.
∠BEA and ∠CED are opposite, which means that they are equal. You can see these equal angles in the image.
This means that the triangles ABE and DCE have the same angles as each other, and are therefore similar.
This means:
AE/ED=AB/DC=5m/10m=1/2
Therefore AE=1/3AD
This means E is 1/3 of the way up from the floor to D, so is at a height of 10/3m=3 1/3m

write the equation of an ellipse with center at (2, 1), one vertex at (2, -4), and one focus at (2, -2)
An ellipse is defined as the set of all points such that the sum of the distances between the point and the two foci is constant. The equation of an ellipse can be represented in the standard form as:
(x-h)^2/a^2 + (y-k)^2/b^2 = 1
where (h, k) is the center of the ellipse, a is the distance from the center to a vertex, and b is the distance from the center to the focus.
Given that the center of the ellipse is at (2, 1), one vertex is at (2, -4), and one focus is at (2, -2), we can use this information to find the values of a and b, and represent the equation of the ellipse:
a = distance from center to vertex = |1 - (-4)|/2 = 2.5
b = distance from center to focus = |1 - (-2)|/2 = 1.5
The equation of the ellipse is:
(x-2)^2/2.5^2 + (y-1)^2/1.5^2 = 1
which can also be written as:
(x-2)^2/6.25 + (y-1)^2/2.25 = 1
This equation represents the ellipse with center at (2, 1), one vertex at (2, -4), and one focus at (2, -2)

= 1/2 X 8 X 3.15
= 12.60 sq units
b)
Below the x-axis, the graph is a rectangle and a triangle
The area of the rectangle = length X width
Here length is the distance of the co-ordinates of the y-axis and width is the distance between the coordinates for the x-axis
Hence we get
(0 - (-5.14))(8 - 0)
= 5.14 X 8
= 41.12 sq units for the rectangle.
The area of the triangle will be
1/2 X (18 - 15.48) X (0 - (-1.05))
1/2 X 2.52 X 1.05
= 1.323 sq unit
Hence, the total area is
41.12 + 1.323
= 42.443 sq unit
c)
Since the area under the graph represents change,
Here we see that the change in the average cell phone bill will be
42.443 + 12.6
= 55.043

Which sign makes the following statement true?
1/4 _____ 5/16
Answer:
2. <
Step-by-step explanation:
To compare these two fractions we can first find them a common denominator. A common denominator between 4 and 16 is 16.
To get from 16 from 4 we multiply by 4 so we do the same to the numerator, changing 1/4 to 4/16.
5/16 already has a denominator of 16 so we can leave that one as is.
4/16___5/16
In this form it is obvious that 5/16 is the larger fraction because 5 is larger than 4, meaning that 5/16 is larger than 1/4.

Cotangent is the inverse of tangent:
cotΘ = 1/tanΘ
cotΘ = [tex]1/\frac{\sqrt{6} }{2}[/tex]
=[tex]\frac{2}{\sqrt{6}}[/tex]
=[tex]\frac{2}{\sqrt{6}}*\frac{\sqrt{6}}{\sqrt{6}}=\frac{2\sqrt{6}}{6}[/tex] Rationalize the denominator
cotΘ = [tex]\frac{\sqrt{6}}{3}[/tex]
Plug and solve.
[tex]\frac{\frac{\sqrt{6}}{2}+\frac{\sqrt{6}}{3} }{\frac{\sqrt{6}}{2}-\frac{\sqrt{6}}{3}}[/tex]
We'll break the problem into 2, simplify the denominator, then simplify the numerator.
Simplify the denominator with the common denominator 6, of 2 and 3:
[tex]{\frac{\sqrt{6}}{2}-\frac{\sqrt{6}}{3} = {\frac{3\sqrt{6}}{6}-\frac{2\sqrt{6}}{6} = {\frac{3\sqrt{6}-2\sqrt{6}}{6} = {\frac{\sqrt{6}}{6}[/tex]
Simplify the Numerator with the common denominator 6, of 2 and 3:
[tex]{\frac{\sqrt{6}}{2}+\frac{\sqrt{6}}{3} = {\frac{3\sqrt{6}}{6}+\frac{2\sqrt{6}}{6} = {\frac{3\sqrt{6}+2\sqrt{6}}{6} = {\frac{5\sqrt{6}}{6}[/tex]
Back in original equation with simplified numerator and denominator:
[tex]\frac{\frac{5\sqrt{6}}{6}}{\frac{\sqrt{6}}{6}}[/tex]
Multiply by reciprocal and simplify:
[tex]\frac{5\sqrt{6}}{6}*\frac{6}{\sqrt{6}} = \frac{5\sqrt{6} * 6}{6\sqrt{6}} = 5*\frac{6\sqrt{6}}{6\sqrt{6}} = 5*1 = 5[/tex]
