What is tree diagram ?
A tree diagram is a tool in the fields of general mathematics, probability, and statistics that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.
Tree diagrams, also known as probability trees or decision trees, are quite versatile and may be useful in many fields, including finance.
A tree diagram lets a user start at a single point and make mutually exclusive decisions or experience mutually exclusive events to follow a path down the branches of the tree. Using a tree diagram is simple once you assign the appropriate values to each node.

what will be the cost of a carpeting a rectangular room of 6 m long and 4 m wide with the carpet of width 1.5 m at rupees 200 per metre
need explanation pls....
(>0<；)
To determine the cost of carpeting the room, we first need to calculate the area of the room that needs to be carpeted.
The area of the room is:
A = l × w
A = 6 m × 4 m
A = 24 square meters
Next, we need to determine the area of the carpet required. Since the carpet has a width of 1.5 m, we can think of the room as being covered by a series of strips of carpet, each of width 1.5 m. We need to calculate the length of each strip and then multiply that by the width of the carpet.
The length of each strip is equal to the length of the room, which is 6 m. So, the area of each strip of carpet is:
A_strip = l × w_carpet
A_strip = 6 m × 1.5 m
A_strip = 9 square meters
To cover the entire room, we will need to use several strips of carpet. The number of strips required is the total area of the room divided by the area of each strip:
Number of strips = A / A_strip
Number of strips = 24 square meters / 9 square meters
Number of strips = 2.6667 strips
Since we cannot use a fractional number of strips, we will need to round up to 3 strips of carpet.
The total area of carpet required is the area of each strip multiplied by the number of strips:
Total area of carpet = A_strip × Number of strips
Total area of carpet = 9 square meters × 3
Total area of carpet = 27 square meters
Finally, we can calculate the cost of carpeting the room at the given rate of rupees 200 per meter:
Cost of carpeting = Total area of carpet × Cost per meter
Cost of carpeting = 27 square meters × Rs. 200 per meter
Cost of carpeting = Rs. 5,400
Therefore, the cost of carpeting the rectangular room of 6 m long and 4 m wide with the carpet of width 1.5 m at rupees 200 per meter would be Rs. 5,400.
The textbook says c = (1,2,3,4)
but according to my solution in the picture below,
I got c = (1,2,2,2).
Where did I get wrong?
(Don't mind the Korean words!
This question is about matrix factorization.)
According to the information the mistake is in the calculation of the vector y. According to your solution, y = [3, 2, 1, 0], but it should actually be y = [2, 2, 2, 2].
How to find the misftake?To see why, let's go back to the definition of y. We have:
y = c - Ax
Plugging in the given values, we get:
y = [1, 2, 3, 4] - [[1, 1, 0, 0], [0, 1, 1, 0], [0, 0, 1, 1]] [x1, x2, x3, x4]
Simplifying this matrix multiplication, we get:
y = [1-x1-x2, 2-x2-x3, 3-x3-x4, 4-x4]
Now we need to solve for x1, x2, x3, and x4 such that y = [2, 2, 2, 2]. That means we have the following system of equations:
1 - x1 - x2 = 2
2 - x2 - x3 = 2
3 - x3 - x4 = 2
4 - x4 = 2
Solving this system, we get x1 = -1, x2 = -1, x3 = 0, and x4 = 2. Plugging these values back into the equation for y, we get y = [2, 2, 2, 2], which is the correct solution.
So it looks like the mistake was in the calculation of y, which led to incorrect values for x1, x2, x3, and x4, and ultimately an incorrect value for c.

Write a quadratic function f whose only zero is 5.
Step-by-step explanation:
a quadratic function means it has an "x²" based term as highest x exponent.
and as such it has 2 zeroes.
the request here simply means that both zeros must be equal and 5.
remember, factoring the function expression tells us the zeroes right away.
now we reverse the process.
we know the zeroes (5 - two times).
so we define the factors to have the desired zeroes :
y = (x - 5)(x - 5)
you see what i did there ? we need to have a quadratic equation, and therefore 2 zeroes. both with the value of 5.
y = (x - 5)(x - 5) = x² - 5x - 5x + 25 = x² - 10x + 25
A quadratic function with only one zero can be derived using the vertex form of a quadratic function, where h equals the zero. Hence, a possible quadratic function with five as the only zero is f(x) = (x - 5)^2.
Explanation:
In mathematics, a quadratic function is written in the form f(x) = ax2 + bx + c.
If a quadratic function has only one zero or root, it means that the parabola touches the x-axis at that point only.Considering the given zero from the question, we have the zero equals 5.By using the concept of vertex form of a quadratic function which is f(x) = a(x-h)2 + k, where (h,k) is the vertex of the parabola, we can create a quadratic function with 5 as the only zero by setting h = 5 and a ≠ 0, k can be any value.So, a potential function could be f(x) = (x - 5)2.

Use elimination and back substitution to solve for x and y in the system of linear equations below.
Answer:
(-2,-8)
Step-by-step explanation:
6x + 7y = -68
-2x + 7y = -52
Time the first equation by -1
-6x - 7y = 68
-2x + 7y = -52
-8x = 16
x = -2
Now put -2 in for x and solve for y
6(-2) + 7y = -68
-12 + 7y = -68
7y = -56
y = -8
Let's Check
6(-2) + 7(-8) = -68
-12 - 56 = -68
-68 = -68
So, (-2, -8) is the correct answer.

What is hyperbola?A hyperbola is a two-dimensional, closed-curve shape with two branches, each of which is a mirror image of the other.
This equation is in the standard form of a hyperbola equation, which is
(x-h)²/a² - (y-k)²/b² = 1, where (h,k) is the center of the hyperbola and a and b are the distance from the center to the vertices of the hyperbola.
In this case, the center of the hyperbola is (1,1).
This can be determined by taking the average of the coordinates of the two vertices, (1,-1) and (1,3), which is (1,1).
The distance from the center to the vertices of the hyperbola is 8 for the x-coordinate, and 4 for the y-coordinate.
This can be determined by taking the difference of the coordinates of the vertices, which is 8 for the x-coordinate and 4 for the y-coordinate.
Therefore, the standard form of the equation that describes the hyperbola is (x-1)²/16-(y-1)²/4=1.

How many three-digit positive integers x are there, such that subtracting the sum of digits of x from x gives a three-digit number whose digits are all the same?
Answer:
Step-by-step explanation:Let $x$ be a three-digit positive integer, and let $a$, $b$, and $c$ be the digits of $x$. Then we want $x - (a + b + c)$ to be a three-digit number whose digits are all the same. This means that $x - (a + b + c) = 111$, $222$, $\ldots$, or $888$.
If $x - (a + b + c) = 111$, then we have $x = a + b + c + 111$. Since $x$ is a three-digit number, $1 \leq a \leq 9$, $0 \leq b \leq 9$, and $0 \leq c \leq 9$. Thus, there are $9 \cdot 10 \cdot 10 = 900$ possible values of $x$ that give a three-digit number whose digits are all $1$.
Similarly, we have $x = a + b + c + 222$, $x = a + b + c + 333$, $\ldots$, and $x = a + b + c + 888$. Each of these equations gives $900$ possible values of $x$.
Therefore, there are a total of $8 \cdot 900 = \boxed{7200}$ three-digit positive integers $x$ that satisfy the conditions of the problem.

If noah had 5 dollars and diego has 150% as noah how much does Diego.
Answer: 7.5
Step-by-step explanation: Because Noah has five dollars, 100% of 5 is 5, and 50% of 5 is 2.5 so Diego has 7.5 dollars.
Answer:
$7.5
Step-by-step explanation:
There are two ways to solve this:
1) First, write the equation:
150% of 5
Then calculate:
[tex]\frac{150}{100} *5[/tex]
Finally, simplify 1 zero with the 0 in 15:
1.5 * 5
= $7.5
2) For the second way, because 150 is more than over 100 (percent), you deduct 150 and 100:
150 - 100 = 50
Then find 50% of 50:
[tex]\frac{50}{100} *5[/tex]
Then cancel 1 zero in 100 with the zero in 50:
0.5 * 5
= 2.5
Finally, add the product with the original amount of Noah:
5 + 2.5
= $7.5

7 ft
5 ft
6 ft
5 ft
Therefore, the surface area of the second figure is 3049.6 square feet, and its volume is 11,483.68 cubic feet.
What is volume?Volume is a measure of the amount of space that a three-dimensional object occupies. It is the measure of how much space is enclosed within a boundary in three dimensions. In simple terms, volume is the amount of space that an object occupies. It is measured in cubic units such as cubic meters (m³), cubic centimeters (cm³), cubic feet (ft³), or gallons (gal).
Here,
To find the surface area and volume of the second figure, we need to know the dimensions of the figure. Since the second figure is similar to the first one, we know that the ratios of the corresponding sides of the two figures are equal. Let x be the unknown scale factor between the two figures. Then, we have:
x = 19/5 (the ratio of the heights of the two figures)
So, we can find the other dimensions of the second figure by multiplying the corresponding dimensions of the first figure by x.
The dimensions of the first figure are:
Height = 5 ft
Length = 6 ft
Width = 7 ft
Multiplying these dimensions by x, we get:
Height = 19 ft (given)
Length = 6 * (19/5) = 22.8 ft
Width = 7 * (19/5) = 26.6 ft
Now, we can find the surface area and volume of the second figure.
Surface area = 2lw + 2lh + 2wh
= 2(22.8 * 26.6) + 2(22.8 * 19) + 2(26.6 * 19)
= 3049.6 ft²
Volume = lwh
= 22.8 * 19 * 26.6

Answer A is 4 units by 2 units, Answer B is the needed 5 units by 2 units, Answer C is 7 units by 2 units, and Answer D is 6 units by 2 units. This leaves us with Answer B.
Quadrilateral ABCD has vertices A(2,4), B(5, 4), C(8, 1), and D(5, 1). Graph the image of quadrilateral ABCD after a dilation centered at D with a scale factor of
followed by a reflection in the line x = 1.
The final image of quadrilateral ABCD after a dilation centered at D with a scale factor of 2, followed by a reflection in the line x = 1, is attached below, where A', B', C', and D' are the new points after the transformation.
What are Transformation and Reflection?
Single or multiple changes in a geometrical shape or figure are called Geometrical Transformation. A geometrical transformation in which a geometrical figure changes his position to his mirror image about some point or line or axis is called Reflection.
First, we need to apply the dilation centered at point D with a scale factor of 2. To do this, we will multiply the coordinates of each point by 2, with D as the center of dilation.
Point D remains the same since the scale factor does not affect it:
D(5, 1)
To find the new coordinates of points A, B, and C, we will use the following formula:
New Point = Center of Dilation + Scale Factor * (Original Point - Center of Dilation)
For point A:
New A = D + 2 * (A - D)
New A = (5, 1) + 2 * (-3, 3)
New A = (-1, 7)
For point B:
New B = D + 2 * (B - D)
New B = (5, 1) + 2 * (0, 3)
New B = (5, 7)
For point C:
New C = D + 2 * (C - D)
New C = (5, 1) + 2 * (3, -3)
New C = (11, -5)
Now that we have the new coordinates, we can reflect the image in the line x = 1. To do this, we will reflect each point across the line x = 1 by replacing the x-coordinate with its reflection across the line.
The equation of line x = 1 is a vertical line passing through x = 1. Therefore, to reflect a point across this line, we need to find the difference between the x-coordinate of the point and the line (which is 1), and subtract that difference from the line.
For point D:
D(5, 1) reflected in x = 1 is (2, 1)
For point A:
New A(-1, 7) reflected in x = 1 is (-3, 7)
For point B:
New B(5, 7) reflected in x = 1 is (-3, 7)
For point C:
New C(11, -5) reflected in x = 1 is (13, -5)
Hence, The final image of quadrilateral ABCD after a dilation centered at D with a scale factor of 2, followed by a reflection in the line x = 1, is attached below, where A', B', C', and D' are the new points after the transformation.

12. Pure fruit concentrate must be diluted with water in the ratio 1:7.
How many millilitre of concentrate are needed to make 5litres cool drink?
By answering the presented question, we may conclude that To prepare ratio 5 litres of cold drink, we'll need 625 millilitres of pure fruit concentrate.
what is ratio?In mathematics, ratios demonstrate how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit plate, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, whereas the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of integers a and b represented as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one male and three girls (for every boy she has three daughters), 3/4 are girls and 1/4 are boys.
If the concentrate-to-water ratio is 1:7, it signifies that the final product requires 7 parts water for every 1 part concentrate. As a result, the total number of components in the combination is 1+7=8.
To produce 5 litres of the cold drink, we must first establish the quantity of concentrate necessary to make 8 parts, and then multiply this figure by 5 litres.
As a result, we need 1 part concentrate and 7 parts water to create 8 parts.
As a result, we require 1/8th of 5,000 millilitres of concentrate, or 625 millilitres.
To prepare 5 litres of cold drink, we'll need 625 millilitres of pure fruit concentrate.

Follow these steps to graph y = 2x - 1 and y = -x + 3:
To plot, pick a set of x-values. For instance, you could select -5 x 5.
For each equation, enter x values to determine the associated y values. You can create a table to aid with work organization:
Draw a coordinate plane and plot the points from your table there. For instance, the first row of the table is represented by the point (-5, -11).
For each equation, draw a straight line to join the points. The slope of the line for y = 2x - 1 will be positive, whereas the slope of the line for y = -x + 3 will be negative.
Use a graphing calculator to double-check your work and make sure your graph matches the one in the image.
Simply enter the equations into the calculator and use the graphing option to visualize these equations.
