When the same variety of radish is grown in the same
way but with fertilizer added, the weights of the
radishes produced are also normally distributed, but
with mean 140 g and standard deviation 40g.
Determine the proportion of radishes grown:
d) With fertilizer with weights less than 60 grams
e) With fertilizer with weights between 20 and 60 g
f) With fertilizer with weights greater than 60 g
Answer:
Step-by-step explanation:
a) Without fertilizer with weights less than 50 grams:
Let X be the weight of radishes produced without fertilizer. Then, X ~ N(40, 10^2).
We need to find P(X < 50).
Using the standard normal distribution, we have:
Z = (X - 40)/10
P(X < 50) = P(Z < (50-40)/10) = P(Z < 1) = 0.8413 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown without fertilizer with weights less than 50 grams is 0.8413.
b) Without fertilizer with weights between 20 and 60 g:
We need to find P(20 < X < 60).
Using the standard normal distribution, we have:
Z1 = (20 - 40)/10 = -2
Z2 = (60 - 40)/10 = 2
P(20 < X < 60) = P(-2 < Z < 2) = 0.9544 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown without fertilizer with weights between 20 and 60 grams is 0.9544.
c) Without fertilizer with weights greater than 60 g:
We need to find P(X > 60).
Using the standard normal distribution, we have:
Z = (60 - 40)/10 = 2
P(X > 60) = P(Z > 2) = 0.0228 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown without fertilizer with weights greater than 60 grams is 0.0228.
d) With fertilizer with weights less than 60 grams:
Let Y be the weight of radishes produced with fertilizer. Then, Y ~ N(140, 40^2).
We need to find P(Y < 60).
Using the standard normal distribution, we have:
Z = (60 - 140)/40 = -2
P(Y < 60) = P(Z < -2) = 0.0228 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown with fertilizer with weights less than 60 grams is 0.0228.
e) With fertilizer with weights between 20 and 60 g:
We need to find P(20 < Y < 60).
Using the standard normal distribution, we have:
Z1 = (20 - 140)/40 = -3
Z2 = (60 - 140)/40 = -2
P(20 < Y < 60) = P(-3 < Z < -2) = 0.0668 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown with fertilizer with weights between 20 and 60 grams is 0.0668.
f) With fertilizer with weights greater than 60 g:
We need to find P(Y > 60).
Using the standard normal distribution, we have:
Z = (60 - 140)/40 = -2
P(Y > 60) = P(Z > -2) = 0.9772 (using a standard normal table or calculator)
Therefore, the proportion of radishes grown with fertilizer with weights greater than 60 grams is 0.9772.

In the figure below, find the exact value of . (Do not approximate your answer.)
The value for x is 4√3. The solution has been obtained by using the Pythagoras theorem.
What is Pythagoras theorem?
Pythagoras' Theorem states that the square of a right - angled triangle's hypotenuse side is equal to the sum of the squares of its other two sides.
We are given the length of the hypotenuse to be 8.
Let the base be 'y'.
So, using Pythagoras theorem,
[tex]x^{2} + y^{2} = 8^{2}[/tex]
From this, we get
[tex]y^{2} = 8^{2} - x^{2}[/tex] ...(1)
Also,
[tex]2^{2} + Perpendicular^{2} = y^{2}[/tex] ...(2)
From the figure, we also know that
[tex]6^{2} + Perpendicular^{2} = x^{2}[/tex]
So,
[tex]Perpendicular^{2} = x^{2} - 6^{2}[/tex]
On substituting this in (2), we get
[tex]2^{2} + x^{2} - 6^{2} = y^{2}[/tex] ...(3)
On equating (2) and (3), we get
⇒[tex]2^{2} + x^{2} - 6^{2} = 8^{2}-x^{2}[/tex]
⇒ 4 + [tex]x^{2}[/tex] - 36 = 64 - [tex]x^{2}[/tex]
⇒ [tex]2x^{2}[/tex] - 32 = 64
⇒ [tex]2x^{2}[/tex] = 96
⇒ [tex]x^{2}[/tex] = 48
⇒ x = 4√3
Hence, the value for x is 4√3.

What is the meaning of "a group under composition"?
The resulting set of isometries, together with the operation of composition, forms a group.
Define the term "a group under composition" in given paragraph?In the context of the paragraph, "a group under composition" refers to a group that is formed by combining isometries (permutations that preserve distances) of a geometric configuration through the operation of composition.
In other words, if you have a set of isometries of a geometric configuration (such as translations, rotations about a point, and symmetries about a straight line), you can combine them through composition (applying one after the other) to obtain new isometries. The resulting set of isometries, together with the operation of composition, forms a group, which is called the group of isometries of the configuration.
This group has certain properties, such as closure (meaning that the result of composing two isometries is also an isometry), associativity (meaning that the order of composition doesn't matter), identity (meaning that there is an isometry that leaves all points fixed), and inverses (meaning that for every isometry, there is another isometry that undoes its effect). These properties make the group a useful tool for studying the symmetries and transformations of geometric configurations in fields such as crystallography and quantum mechanics.

Straight Line Graphs Question. I tried to solve the section (a) part of the question correctly I followed the gradient method plugging in the values and got [tex]y = \frac{1}{6} x + 1.6 (recurring). However the answer is y = \frac{1}{2} x + 3.[/tex]. Where am I going wrong? Can someone explain step by step how to solve this please.
The equation of the straight line joining A to B is y = (1/2)x + 3, the equation of the straight line joining B to C is y = (1/2)x + 3, and A, B, and C are collinear.
What are collinear points?
Collinear points are three or more points that lie on the same straight line. In other words, if three points A, B, and C are collinear, then there exists a straight line that passes through all three points. To determine if three or more points are collinear, we can find the slope of the line that passes through any two of the points. If the slope is the same for all possible pairs of points, then the points are collinear. Otherwise, they are not collinear.
a) To find the equation of the straight line joining A to B, we can use the slope-intercept form of the equation of a line:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
The slope of the line passing through A and B is:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (-8, -1) and (x₂, y₂) = (-4, 1).
m = (1 - (-1)) / (-4 - (-8)) = 2/4 = 1/2
To find the y-intercept, we can use the point-slope form of the equation of a line:
y - y₁ = m(x - x₁)
where (x₁, y₁) = (-8, -1) and m = 1/2.
y - (-1) = (1/2)(x - (-8))
y + 1 = (1/2)(x + 8)
y = (1/2)x + 3
Therefore, the equation of the straight line joining A to B is y = (1/2)x + 3.
b) To find the equation of the straight line joining B to C, we can use the same method:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (-4, 1) and (x₂, y₂) = (12, 9).
m = (9 - 1) / (12 - (-4)) = 8/16 = 1/2
Using point-slope form with the point (x₁, y₁) = (-4, 1) and slope m = 1/2:
y - 1 = (1/2)(x - (-4))
y - 1 = (1/2)x + 2
y = (1/2)x + 3
Therefore, the equation of the straight line joining B to C is y = (1/2)x + 3.
c) From the equations of the lines joining A to B and B to C, we can see that both lines have the same slope of 1/2. This implies that the three points A, B, and C are collinear, i.e., they lie on the same straight line.

What is expression?In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, −, ×, ÷, ^) that represents a quantity or a mathematical relationship between quantities. Expressions can include variables, which are letters that represent unknown or varying values. Expressions can be simple or complex, and they can be used to represent mathematical formulas, equations, inequalities, and functions. Expressions can be evaluated by replacing the variables with specific values and performing the arithmetic operations according to the rules of algebra. Expressions can also be simplified by combining like terms, distributing multiplication, and factoring. Simplifying expressions can help us to better understand their structure and relationships, and it can make them easier to work with in calculations and problem-solving.
Here,
To perform the operation (8x² + 3x - 4) + (-2x² + 8x), we need to combine like terms, i.e., terms that have the same variable and exponent.
First, let's combine the x² terms:
8x² - 2x² = 6x²

How to find a surface area with 2in 6in 10in 8in 2in
The surface area of the rectangular prism is 376 square inches.
What is surface area?Surface area is the total area that the surface of a 3-dimensional object covers, including all of its faces and sides. It is measured in square units.
To find the surface area of a 3-dimensional object with dimensions of 2in, 6in, 10in, 8in, and 2in, you will need to add up the areas of each of its faces.
Assuming that the object is a rectangular prism, here are the steps to find its surface area:
Identify the dimensions of the rectangular prism: length, width, and height.
Length: 10in
Width: 8in
Height: 6in
Calculate the area of each face:
Front and back faces: length x height = 10in x 6in = 60 sq.in x 2 = 120 sq.in
Top and bottom faces: width x length = 8in x 10in = 80 sq.in x 2 = 160 sq.in
Side faces: height x width = 6in x 8in = 48 sq.in x 2 = 96 sq.in
Add up the areas of each face to get the total surface area:
Total surface area = 120 sq.in + 160 sq.in + 96 sq.in = 376 sq.in

The net present value of the project is $0.15 million.
What is the net present value?Net present value is the present value of after-tax cash flows from an investment less the amount invested.
hee, we have,
The first step is to determine the cash flow of the project.
Cash flow = (sales - cost - depreciation) × (1 - tax) + depreciation
Depreciation = (cost of the asset ) / useful life
Depreciation = $2.18 million / 3
Depreciation = 0.727 million
Cash flow = (1.645 - 0.61 - 0.727) x (1 - 0.21) + 0.727 = $0.97 million
Net present value = -2.18 million + 0.97 / 1.12 + 0.97 / 1.12² + 0.97 / 1.12³

At the hardware store, a zinc washer has an inner radius of r inches and a width of 1 inch from inner edge to outer edge. Write a polynomial equation for the area A of one side of the zinc washer.
A polynomial equation for the area of one side of the zinc washer is given by A = pi*(r+1)² - pi*r².
What is polynomial?Polynomial is a mathematical expression containing one or more terms, each of which is composed of a constant coefficient and one or more variables raised to a power. It can be used to represent a variety of functions, such as linear, quadratic, and cubic functions.
This equation is derived from the area formula for a circle, which states that the area of a circle is equal to pi multiplied by the square of the radius. In this case, the inner radius of the zinc washer is r and the outer radius is r + 1, so the area of one side of the zinc washer is equal to the area of a circle with a radius of r + 1 minus the area of a circle with a radius of r. This can be expressed mathematically as pi*(r+1)² - pi*r², which is a polynomial equation for the area of one side of the zinc washer.
