The median of this data set is 30. If the largest observation (50) were deleted, the median would become 25, which is a 5 unit change.
Here's a data set with five observations for which the median would change significantly if the largest observation were deleted:
Observation 1: 20
Observation 2: 25
Observation 3: 30
Observation 4: 35
Observation 5: 50
The median of this data set is 30. If the largest observation (50) were deleted, the median would become 25, which is a 5 unit change. This is a significant change because the median is a measure of central tendency that shows the midpoint of a set of data and is sensitive to outliers. By removing the largest observation, the data set is no longer skewed towards larger values, and the median changes to reflect this.

x/6x+25 domain i don't understand how to get this domain
The answer of the given question based on the finding the domain of the equation the answer is the domain of the function f(x) = x/(6x + 25) is all real numbers except x = -25/6. In interval notation, we can write the domain as: (-∞, -25/6) U (-25/6, ∞)
What is Function?In mathematics, function is rule or mapping that assigns unique output or value to each input or element from given set. A function can be thought of as machine that takes an input and produces an output, where output depends on input and specific rule that defines function.
To find the domain of the function f(x) = x/(6x + 25), we need to identify any values of x that would make the denominator zero or undefined.
So, we need to solve the equation 6x + 25 = 0 for x:
6x + 25 = 0
6x = -25
x = -25/6
Since x = -25/6 would make the denominator zero, we need to exclude this value from the domain of the function.
Therefore, the domain of the function f(x) = x/(6x + 25) is all real numbers except x = -25/6. In interval notation, we can write the domain as:
(-∞, -25/6) U (-25/6, ∞).

Solution check for this math problem
1. The solutions of the equation 6/(x+1)= x/(x-1) are x = 2 and x = 3.
2. The solutions of the equation x+ 4/x= -5 are x = -1 and x = -4.
What are the solutions ?
1. 6/(x+1) = x/(x-1)
To solve this equation, we first need to get rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators, which is (x+1)(x-1):
6(x-1) = x(x+1)
Expanding the left side, we get:
6x - 6 = x² + x
Moving all the terms to one side, we get:
x² - 5x + 6 = 0
This is a quadratic equation that can be factored as:
(x - 2)(x - 3) = 0
So, the solutions are x = 2 and x = 3. However, we need to check if these solutions are valid, because we cannot divide by zero.
Checking x = 2:
6/(2+1) = 2/(2-1)
2 = 2, which is true
Checking x = 3:
6/(3+1) = 3/(3-1)
3/2 = 3/2, which is true
Therefore, the solutions are x = 2 and x = 3.
2. x + 4/x = -5
To solve this equation, we first need to get rid of the fraction by multiplying both sides of the equation by x:
x² + 4 = -5x
Moving all the terms to one side, we get:
x² + 5x + 4 = 0
This is a quadratic equation that can be factored as:
(x + 1)(x + 4) = 0
So, the solutions are x = -1 and x = -4. However, we need to check if these solutions are valid, because we cannot divide by zero.
Checking x = -1:
-1 + 4/(-1) = -5
-1 - 4 = -5, which is true
Checking x = -4:
-4 + 4/(-4) = -5
-4 - 1 = -5, which is true
Therefore, the solutions are x = -1 and x = -4.

which of the following rotational symmetries apply to the regular octagon
Answer:
Rotational symmetry of 135° about the origin: Yes
Rotational symmetry of 180° about the origin: Yes.
Step-by-step explanation:
Notice that the figure is a regular octagon, then, the figure has a rotational symmetry for multiple of 1/8 of a whole turn. To find the measure of the minimum angle of symmetry, divide 360 by 8:
\( \frac{360}{8} = 45\)
The regular octagon will have rotational symmetry about the origin for any angle which is multiple of 45°.
Divide 135° and 180° by 45° to check if they are multiples of 45°.
\( \frac{135}{45} = 3 \\ \frac{180}{45} = 4\)
Since both fractions are intengers, then both 135° and 180° are multiples of 45°.
Then, the regular octagon has rotational symmetry in both cases.
Therefore, the answer are;
Rotational symmetry of 135° about the origin: Yes
Rotational symmetry of 180° about the origin: Yes.

The perimeter of the triangle is 350 units. Find the measure of each side (label your answers).
Answer:
125, 105, 120
Step-by-step explanation:
You would first make an equation with what you know:
x + 45 + x + 25 + x + 40 = 350.
Now, you would simplify and add like terms.
3x + 110 = 350
Now, you would subtract 110 from both sides.
3x = 240
Now, you would divide both sides by 3.
x = 80
Now that you know what x is, simply plug it in to the respective equations for all three sides.
x + 45 would become 80 + 45, and add up to 125.
x + 25 would become 80 + 25, and add up to 105.
x + 40 would become 80 + 40, and add up to 120.
To check your work, you would now add the three totals.
125 + 105 + 120 = 350.

Regular consumption of presweetened cereals contributes to tooth decay, heart disease, and other degenerative diseases, according to studies conducted by Dr. W. H. Bowen of the National Institute of Health and Dr. J. Yudben, Professor of Nutrition and Dietetics at the University of London. In a random sample consisting of 20 similar single servings of Alpha-Bits, the average sugar content was 11.3 grams with a standard deviation of 2.45 grams. Assuming that the sugar contents are normally distributed, construct a 95% confidence interval for the mean sugar content for single servings of Alpha-Bits.
Using the t-distribution, the 95% confidence interval for the mean sugar content for single servings of Alpha-Bits is (10.15, 12.45).
In this problem, we have that:
Sample of 20, thus \(n = 20\).Sample mean of 11.3 grams, thus \(\overline{x} = 11.3\).Sample standard deviation of 2.45 grams, thus \(s = 2.45\).The confidence interval is:
\(\overline{x} \pm t\frac{s}{\sqrt{n}}\)
First, we find the number of degrees of freedom, which is one less than the sample size, thus df = 19.
Now, we have to find the critical value for a 95% confidence interval with 19 df, thus, looking at the t-table or using a calculator, t = 2.093.
Then:
\(\overline{x} - t\frac{s}{\sqrt{n}} = 11.3 - 2.093\frac{2.45}{\sqrt{20}} = 10.15\)
\(\overline{x} + t\frac{s}{\sqrt{n}} = 11.3 + 2.093\frac{2.45}{\sqrt{20}} = 12.45\)
The interval is (10.15, 12.45).

The unit rate of computers per day using the graph is that 12 computers are made per day.
What is a unit rate?The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.
How to find the unit rate of computers per dayTo obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x
So, it is given by:
\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)
\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)
\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)
\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)
\(\bold{Slope = 12}\)
Unit rate = 12 computers per day.
