Find the value of x in the equation. 3/4 (8x-6) -2= 1/2-x
In linear equation, the value of x in the equation is 20/11.
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.3/4 (8x-6) -2= 1/2-x
24x - 18 - 2/4 = x/2
24x - 20/4 = x/2
2(24x - 20) = 4x
48x - 40 = 4x
48x - 4x =40
44x = 40
x = 40/44

Those methods involving the collection, presentation, and characterization of a set of data in order to properly describe the various features of that set of data are called descriptive statistics.
Descriptive statistics:- Descriptive statistics helps to describe, summarize and organize the set of data efficiently and in an informative way, so that it'll be easier to make conclusion about the data in order to make rational decisions. This method describes the characteristics of a dataset.
Example:- The average test score for the students of a particular class, gives descriptive sense of the typical scores.
There are three types of descriptive statistics-
Univariate statistics:- It summarizes only one variable at a time.Bivariate statistics:- It compares between two variables.Multivariate statistics:- It compares between more than two variables.Thus we can conclude that, those methods involving the collection, presentation, and characterization of a set of data in order to properly describe the various features of that set of data are called descriptive statistics.

Lucy rolls 2 fair dice and adds the results from each.
Work out the probability of getting a total of 10.
Answer:
Step-by-step explanation:
Discussion
The numbers on each die are 1 to 6.
They are all equally likely to turn up. There are 36 possibilities in all 6*6
So getting a 10 can be done in 3 ways.
6 + 4 = 10
4 + 6 = 10
5 + 5 = 10
You can't get 10 any other way.
So of the 36 ways of throwing 2 dice, only 3 will work.
Answer
P(10)= 3/36 = 1/12 = 0.0833333...

rectangle, parallelogram, or night triangle) on a grid and the scale
factor at which it was created.
Example Stem: This diagram of a rectangular city park was drawn
using a scale factor of 1 centimeter to 20 meters.
In the diagram shown, assume each square on the grid is 1
centimeter in length.
What is the area, in square meters, of the actual park on which this
scale drawing is based?
Scale factor for the drawing from actual park = 1/20
Area of the actual park = 1200 cm²
Area of a Rectangle. A = l × b. The area of any rectangle is calculated, once its length and width are known. By multiplying length and breadth, the rectangle's area will obtain in a square-unit dimension
Length of the rectangular city park = 5 cm
Width of the rectangular park = 6 cm
Using scale factor 1 cm = 20 meters
Scale factor = Length of the park in drawing/ actual length of park
⇒1/20.
5/actual length of park = 1/ 20
Actual length = 5 × 20 = 100 meters
Actual width = 6 × 20 = 120 meters
Area of the rectangular park = length × width
square meters

In the formula for calculating the standard deviation, what does the letter n represent? a. summation b. sample size c. mean score for group d. individual score
The correct option is (b) sample size.
In the formula for calculating the standard deviation, the letter n represent sample size.
What is standard deviation?
Standard deviation is a statistical standard measure in finance that, when applied to an investment's annual rate of return, sheds light on its historical volatility.
Some key features regarding the standard deviation are-
The higher the standard deviation of a security, the larger the variance between every price and the mean, indicating a wider price range.A volatile stock, for example, has a high standard deviation, whereas a stable blue-chip stock has a low deviation.A square root of a value deduced from correlating data points to a population's collective mean is used to calculate standard deviation. The formula is:
Standard Deviation = [tex]\sqrt{\frac{summation n to i=1 (x_{i}-bar x )}{n-1} }[/tex]
Where,
[tex]x_{i}[/tex]= value of the i th point the the given data set.
[tex]barx[/tex]= mean value
n = total number of data points.
Thus, the standard deviation, on the other hand, determines all ambiguity as risk, even when it is in the investor's favor, like above-average returns.

Coordinates of the point that partitions the line into the given ratio is; (1, 5)
How to divide a line segment?
If the ratio dividing a line segment represents a:b, then the formula to divide the line segment is;
Coordinates = {(bx₁ + ax₂)/(a + b), (by₁ + ay₂)/(a + b)}
From our question, we have the ratio as;
1:2. Thus; a = 1 and b = 2
Our coordinate of CD is; C(-1,7) and D(5, 1)
Thus;
x₁ = -1
x₂ = 5

Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets for $20. The venue has the capacity to hold 400 people. The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise $5,000 for her school
A.400
B.300
C.250
D.100
Number of At-the-Door tickets Anna needs to sell to make her goal = 100
Anna is selling pre-sale and at-the-door tickets.
Let 'x' be the number of pre-sale tickets and 'y' be the number of at-the-door tickets.
Price of a pre-sale ticket = $10
Price of an at-the-door ticket = $20
Total price to be raised = $5000
So the equation corresponding is 10x+20y = 5000-----------(1)
Total number of people the venue can hold = 400
Thus the next equation is x+ y = 400---------(2)
From the graph the line with points (0,250) and (500,0) represent the equation (1) since 10 x 0 + 20 x 250 = 5000 and 10 x 500 + 20 x 0 = 5000.
The line with points (0,400) and (400,0) represent the equation (2) as 0+400 = 400 and 400+0 = 400.
So to find x and y we need to solve equations (1) and (2).
10 x (2) ⇒ 10x+10y = 4000-------(3)
Now subtract (3) from (1)
⇒ 10y = 1000
⇒ y = 100
Hence the number of At-the-Door tickets Anna needs to sell to make her goal = 100

If the librarian had a budget of $500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of new-release and classic movies bought?
Answer: Answer is 16 new releases and 22 classic movies.
Step-by-step explanation:
He'll buy 16 new releases and 22 classic movies.
Let x = number of new releases
Let y = number of classics.
The equation to solve the question will be:
20x + 8y = 500
When x= 16 and y = 22, thus will be:
= 20x + 8y
= 20(16) + 8(22)
= 320 + 176
= 496
Therefore, since this is the number closest to $500, therefore this will be the appropriate number of movies that he can buy.
In conclusion, he'll buy 16 new releases and 22 classic movies.
