The outlier of 2 decreases the mean page count.
What is mean and median?
The mean is that the variety you get by dividing the total of a collection of values by the quantity of values within the set.
In distinction, the median is that the middle variety in an exceedingly set of values once those values square measure organized from smallest to largest.
Main Body:
From the picture we can know that outlier of 2 does not effect the median page count.
But outlier of 2 decreases the mean page count.
it can be found out by taking mean
(1+2+3+2+1+2+2+1)/8= 1.75
and if we remove outlier of 2 ,then
(1+3+2+1+2+2+1)/7 = 1.86
Hence ,the outlier of 2 decreases the mean page count.

What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.
According to our question-
(1/5) / (4/10) = x / 1
Cross-multiplication yielding
1/5 * 1 = 4/10 * x

cars doe the class need for this trip? Write a system of equations to solve.
12/24
The number of trucks and cars need by the class for the trip will be 3 and 2 respectively
How to find the number of trucks and cars the class need for this tripInformation from the question is used as follows
There are 22 people going on this trip.
total number = 22
There are four drivers and two types of vehicles, cars and trucks
drivers = 4
vehicle types = 2
The cars set four people, including the driver and the truck seats six people again including drive
cars = 4 people
truck = 6 people
Total number of people + drivers = 26
let the number of people in the truck be t and the number of people in the car be c
6t + 4c = 26
assuming the trucks were 3
6 * 3 + 4c = 26
4c = 26 - 18

9x² + 31x+ 20 = ( ? ) ( ? )
2x² +7x-4 = ( ? )( ? )
2x² - 13x-5 = ( ? )( ? )
Answer: The square root of 169 is 13, so the two solutions for x are:
x = (13 + 13) / 4 = 3.25
x = (13 - 13) / 4 = -0.25
Since the quadratic expression 2x^2 - 13x - 5 equals 0 when x is either 3.25 or -0.25, the factors of this expression are (x - 3.25)(x + 0.25).
In summary, the factors of the first quadratic expression are (x + 1.056)(x + 5.937), the factors of the second expression are (x - 0.75)(x + 3.75), and the factors of the third expression are (x - 3.25)(x + 0.25).
Step-by-step explanation: To find the factors of a quadratic expression, we can use the quadratic formula. The quadratic formula states that for a quadratic expression of the form ax^2 + bx + c = 0, the solutions for x are given by the formula x = (-b ± sqrt(b^2 - 4ac)) / (2a).
In the first equation, a is 9, b is 31, and c is 20. Plugging these values into the quadratic formula, we get:
x = (-31 ± sqrt(31^2 - 4 * 9 * 20)) / (2 * 9)
This simplifies to:
x = (-31 ± sqrt(961 - 720)) / 18
This further simplifies to:
x = (-31 ± sqrt(241)) / 18
We can find the value of the square root by using a calculator or by remembering some common square roots. The square root of 241 is approximately 15.937, so the two solutions for x are:
x = (-31 + 15.937) / 18 = -1.056
x = (-31 - 15.937) / 18 = -5.937
Since the quadratic expression 9x^2 + 31x + 20 equals 0 when x is either -1.056 or -5.937, the factors of this expression are (x + 1.056)(x + 5.937).
We can use the same approach to find the factors of the other two quadratic expressions. For the second expression 2x^2 + 7x - 4, the values of a, b, and c are 2, 7, and -4, respectively. Plugging these values into the quadratic formula, we get:
x = (-7 ± sqrt(7^2 - 4 * 2 * -4)) / (2 * 2)
This simplifies to:
x = (-7 ± sqrt(49 + 32)) / 4
This further simplifies to:
x = (-7 ± sqrt(81)) / 4
The square root of 81 is 9, so the two solutions for x are:
x = (-7 + 9) / 4 = 0.75
x = (-7 - 9) / 4 = -3.75
Since the quadratic expression 2x^2 + 7x - 4 equals 0 when x is either 0.75 or -3.75, the factors of this expression are (x - 0.75)(x + 3.75).
For the third expression 2x^2 - 13x - 5, the values of a, b, and c are 2, -13, and -5, respectively. Plugging these values into the quadratic formula, we get:
x = (13 ± sqrt(13^2 - 4 * 2 * -5)) / (2 * 2)
This simplifies to:
x = (13 ± sqrt(169 + 40)) / 4

The value of the equation log(3 47) is about 4.235.
Describe log.The power to which a number must be increased in order to obtain another number is known as a logarithm. For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2: log 100 = 2.
Given that the approximate values of log(3) and log(47) are 1.1 and 3.85, respectively,
we must determine the approximate value of log(347).
log(a × b) = log(a) × log(b)
we get ,
log(3 × 47) = log(3) × log(47)
substituting , the values of log(3) and log(47) ,
we get ,

For a project in his Geometry class, Feng uses a mirror on the ground to measure the height of his school’s flagpole. He walks a distance of 8.65 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. He then steps 1.1 meters to the other side of the mirror, until he can see the top of the flagpole clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.65 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
The height of the flagpole, found using the ratio of the sides of similar triangles is 12.975 meters
What are similar triangles?Similar triangles are triangles in which two angles of one triangle are congruent to two angles in the other triangle, such that they have the same shape.
The parameters that can be used to find the height of the flagpole are;
Distance of the mirror from the flagpole = 8.65 meters
Distance of Feng on the other side of the flagpole = 1.1 meters
The height from Feng's eyes to the ground = 1.65 meters
According to the law of reflection, the angle of incident and the angle of reflection are the same
The angle made by Feng and the ground = Angle made by the flagpole and the ground = 90°
The triangle formed by the Feng and the flagpole are therefore similar by AA similarity postulate
The ratio of corresponding sides of similar triangles are the same, therefore;
[tex]\dfrac{1.65}{Height\, of \, the \, flagpole} = \dfrac{1.1}{8.65}[/tex]
[tex]Height\, of \, the \, flagpole = \dfrac{1.65}{1.1} \times 8.65 = 12.975[/tex]

The meaning of the standard deviationA measure of how far the data are from the mean is called standard deviation (or). Data that have a low standard deviation are more likely to be centered around the mean than those that have a high standard deviation.

In 2017, a company's sales were about $9 million. Sales increased at an approximately constant rate and reached
about $14.5 million in 2020, Estimate the sales in 2026. Show your work.
Answer: To estimate the company's sales in 2026, we need to find the average increase in sales per year and then use that to predict the sales for 2026.
The total increase in sales from 2017 to 2020 was $14.5 million - $9 million = $<<14.5-9=5.5>>5.5 million.
The number of years from 2017 to 2020 is 2020 - 2017 = <<2020-2017=3>>3 years.
Therefore, the average increase in sales per year was $5.5 million / 3 years = $<<5.5/3=1.83>>1.83 million/year.
Since the average increase in sales per year was $1.83 million/year, we can estimate the sales in 2026 by adding that amount to the sales for each year from 2020 to 2026. For example, the estimated sales for 2021 would be $14.5 million + $1.83 million = $16.33 million. Similarly, the estimated sales for 2022 would be $16.33 million + $1.83 million = $18.16 million, and so on.
Using this method, we can estimate that the sales for 2026 will be $26.73 million.
