The probability that they share the same color is 7/15.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The likelihood that an event will occur increases with its probability.
A straightforward illustration is tossing a fair (impartial) coin.
The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half (which may also be.
According to our question-
Then n(S)= number of ways of drawing 2 balls out of (6+4)=10
Let E= event of getting both balls of same color
Then, n(E)= no of ways (2 balls out of six) or (2 balls out of 4)
= 6C 2+ 4c2
∴P(E)= n(S)/n(E)= 45/21= 15/7

What are the 7 ways to classify a triangle?
Classifying Triangle by Sides or Angles: Equilateral triangle, Isosceles triangles, Scalene triangle, Right triangle, Obtuse triangle, Acute triangle, Equiangular triangle.
What are the seven ways to classify triangles ?A triangle is said to be equilateral or equiangular if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.
A scalene triangle is a triangle with three different side lengths and three different angle measurements. The total of all internal angles, however, is always equal to 180 degrees.
A triangle with two sides that have the same length is said to be isosceles. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

How do polynomial identities apply to complex numbers?
Polynomial identities can be applied to complex numbers in the same way they are applied to real numbers, by replacing the real numbers in the polynomial with complex numbers and following the same algebraic rules and procedures.
What is a complex number?
A complex number is a number that can be written in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1.
Polynomial identities are equations that are always true for any values of the variables, regardless of whether the variables represent real numbers or complex numbers. Complex numbers can be represented in the form of a + bi, where a and b are real numbers and i is the imaginary unit.
For example, the identity[tex](x + y)^2 = x^2 + 2xy + y^2[/tex] is true for any real numbers x and y, and it also applies to complex numbers a + bi and c + di. The identity becomes [tex](a + bi + c + di)^2 = (a + c)^2 + 2(a + c)(bi + di) + (bi + di)^2[/tex]
Another example is the identity [tex](a+bi)^2 = a^2 + 2abi - b^2[/tex] which is always true for any complex number a+bi. This identity applies to any complex number and can be used to simplify polynomials involving complex numbers.
Hence, polynomial identities can be applied to complex numbers in the same way they are applied to real numbers, by replacing the real numbers in the polynomial with complex numbers and following the same algebraic rules and procedures.

Write two equations that represent the graph shown below- one equation using sine, and one equation using cosine.
Two equations that represent the graph shown below as sine function y = 0.909x−3 and as cosine function y = −0.416x −3.
What is sine function?The sine graph or sinusoidal graph is an up-down graph and repeats every 360 degrees i.e. at 2π.
The general form of a cosine function is:
y = a cosb (θ±c) ± d

What is a dilation of a line?
A dilation of a line is a transformation that changes the size of the line but preserves its shape.
It is a type of similarity transformation. A dilation can either be a reduction, in which the line is made smaller, or an enlargement, in which the line is made larger. In both cases, the line's shape is preserved, but the size is changed.
The center of dilation, also known as the scale factor, is a fixed point around which a dilation takes place. The scale factor is a value that represents the amount of change in size, it can be greater than 1 for an enlargement or less than 1 for a reduction.
In geometry, a dilation is represented by a multiplication of the coordinates of a point by a scale factor. For example, a dilation of a line with a scale factor of 2 will result in the line being twice as long as the original line.
In conclusion, a dilation of a line is a transformation that changes the size of the line but preserves its shape. The center of dilation or scale factor is a fixed point around which a dilation takes place and is represented by a multiplication of the coordinates of a point by a scale factor.
It can be either an enlargement or a reduction depending on the scale factor value.

What type of triangle has side lengths 5'7 and 11?
As the triangle cannot be equilateral since the sides are not equal. So the obtuse triangle has side lengths 5, 7 and 11.
Assume that a triangle has sides that measure 5, 7, and 11.
Finding the sum of the squares on the triangle's two shorter sides and comparing it to the square on the longest side will reveal the type of triangle.
A triangle must be sharp in order to:
Let a = 5, b = 7 and c = 11
a^2 + b^2 = (5)^2 + (7)^2 = 25 + 49 = 74
c^2 = (11)^2 = 121
(1) If the triangle is
a^2 + b^2 > c^2
Therefore, the triangle is not acute.
(2) Eqviangular means that each internal angle must be 60 degrees in length.
As a result, the triangle is not eqviangular.
(3) The triangle cannot be equilateral since the sides are not equal.
(4) We note that a^2 + b^2 = c^2.
The triangle is hence obtuse.

Using the formula of Simple Interest, the value for the principal amount is obtained to be P = $1333.33.
What is Simple Interest?
Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
The value for Simple Interest is given as = $180
The value for rate is given as = 4.5%
The value for time is given as = 3 years
To find the value for Principal amount, follow the formula for Simple Interest -
SI = P R T/100
Where P is the principal amount, R is the rate and T is the time.
Substitute the values in the equation -
180 = (P × 4.5 × 3)/100
180 = 13.5P / 100
P = (180 × 100) / 13.5
P = 18000 / 13.5
P = 1333.33

How do you dilate a triangle by 2 with a compass?
Construct a dilate, with scale factor 2, of a triangle using only a ruler and compasses.
What is Dilation ?The center of dilation—the location from where the picture is shrunk or expanded—is necessary to build a dilation. A scale factor, or the quantity that controls how big or tiny the new picture will be, is also necessary. If the scale factor is more than 1, the new picture will be bigger than the original image, creating an enlargement. We see a decrease if the scale factor is less than 1, as the new picture will be smaller than the original image.
Step-1
Let's dilate triangle PQR by a scale factor of 2 with a center of dilation at point C.
Step-2
First, we will use a straightedge to connect the center of dilation C to each vertex. We are going to extend those lines across the whole page.
Step-3
Next, we'll place the point of the compass on the center of dilation C and the pencil on vertex Q and measure that distance.
Step-4
Now, without changing the size of the compass, we will move the point of the compass to vertex Q, and make a mark on the line that is extended through Q.
Step-5
Notice that since we measured the distance from C to Q and then used that same distance to mark the line, we have now created a new point that is twice the distance from C that Q was.
We now repeat the process for each of the other vertices of the triangle.
Step-6
These marks represent the vertices of our dilated image. We often use the same letters with an apostrophe to show that it is the corresponding vertex.
Step-7
Finally, we use the straightedge to connect all of the new vertices.

• The radius of the central circle is 1cm.
• OE and OB form a right angle.
Calculate the perimeter of the egg.
The perimeter of the egg comprising of arcs AB, AC, BD, and CD is π·(6-√2)/2 centimeters
What is the perimeter of a plane figure?The perimeter of a figure is the length of the boundary line of a plane occupied by the figure.
The perimeter of the egg can be found by finding the sum of the lengths of the arcs that together form a composite figure of the perimeter of the egg
The length of arc AC centered at point B is found as follows;
The angle at the center B is the base angle of the isosceles right triangle
The acute angle of an isosceles right triangle is 45°, therefore, the angle at B = 45°
The radius of the arc AC, AB = AO + OB = BC
AO and OB are the radii of the circle with center O
AO = OB = 1 cm
AB = 1 + 1 = 2 = BC
The length of AC = (45/360)× 2×π×2 = π/2
AC = π/2
The radii and angle at the center of arc BD are also 2 cm and 45°
The length of arc BD is therefore, (45/360) × 2 × π × 2 = π/2
BD = π/2
The angle at the center of arc CD = ∠CED
∠CED ≅ ∠AEB (Vertical angle postulate)
∠AEB = ∠AEO + ∠BEO = 45° + 45° = 90°
∠CED = ∠AEB (Definition of congruency)
∠CED = ∠AEB = 90°
The radius of the arc CD, CE = ED = BC - EB
EB = √(1² + 1²) = √2
CE = 2 - √2
Length of arc CD = (90°/360°) × 2 × π × (2 - √2)) = π × (2 - √2))/2
CD = π·(2 - √2)/2
The radius of the arc AB = 1 cm
Angle at the center of arc AB = 180°
Length of arc AB = π × 1 = π
AB = π
The perimeter of the egg = AC + CD + BC + AB
Therefore;
The perimeter of the egg = π/2 + π × (2 - √2))/2 + π/2 + π = π·(6 - √2)/2

A scale model is a physical representation of an object that is geometrically equivalent (known as the prototype).
Since the scale drawing is 3 inches : 10 feet, this means that every 3 inches on the drawing represents 10 feet in real life. Hence, 1 inch on the drawing represents 10/3 = 3.33 feet in real life.
So the patio measures 6 inches by 12 inches on the drawing, which corresponds to 6 * 3.33 feet by 12 * 3.33 feet in real life, or 20 feet by 40 feet.
Therefore, the total area of the patio will be 20 * 40 = 800 square feet.

Is x 8 a factor of the function f x 2x3 17x2 64?
A factor of a polynomial function is a polynomial that divides the function evenly when using polynomial division.
To check if x - 8 is a factor of the function f(x) =[tex]2x^3 - 17x^2 + 64[/tex] , we can use polynomial division.
When dividing f(x) by x - 8, the remainder should be zero.
x - 8 is a factor of the function when the remainder is zero.
In this case, the quotient is [tex]2x^2 + x + 8[/tex] , and the remainder is zero, so x - 8 is a factor of the function f(x) = [tex]2x^3 - 17x^2 + 64.[/tex].
So we can say [tex]f(x) = (x-8)(2x^2 + x + 8)[/tex]
Alternatively, we can also use synthetic division to check if x - 8 is a factor of the function.
Synthetic division is a shorthand method of dividing a polynomial by a linear factor such as x - 8.
If the remainder is zero, then x - 8 is a factor of the function.

Which example illustrates the commutative property of addition for polynomials?
(2x^2 + 5x) = –(–2x2 – 5x)
(2x^2 + 5x) + 0 = (2x^2 + 5x)
(2x^2 + 5x) + (4x^2 – 4x) = 2x^2 + 5x + 4x^2 – 4x
(2x^2 + 5x) + (4x^2 – 4x) = (4x^2 – 4x) + (2x^2 + 5x)
D) The example (2x^2 + 5x) + (4x^2 - 4x) = (4x^2 - 4x) + (2x^2 + 5x) illustrates the commutative property of addition for polynomials.
The commutative property of addition for polynomials states that the order in which polynomials are added does not affect the result of the sum. In other words, it states that if we have two polynomials A and B, the result of adding A and B (A+B) will be the same as adding B and A (B+A).
For example, consider the polynomials (2x^2 + 5x) and (4x^2 - 4x). If we add these two polynomials in the order given, (2x^2 + 5x) + (4x^2 - 4x) = 6x^2 + x. Now, if we add these two polynomials in the reverse order, (4x^2 - 4x) + (2x^2 + 5x) = 6x^2 + x. We can see that the order of the polynomials does not affect the result of the sum, and thus it holds the commutative property of addition.
Option (2x^2 + 5x) + (4x^2 - 4x) = (4x^2 - 4x) + (2x^2 + 5x) illustrates the commutative property of addition for polynomials, because it shows that the order of the polynomials does not matter and it gives the same answer.
It is important to note that the other options does not illustrate the commutative property.

A cylinder with a height of 9cm. And a width of 10cm. Find the exact volume.
A. 90pi cm^3
B. 45pi cm^3
C. 900pi cm^3
D. 225pi cm^3
Answer:
The correct answer is D. 225pi cm^3.
To find the volume of a cylinder, you use the formula:
V = πr^2h
Where V is the volume, π is pi, r is the radius of the base, and h is the height of the cylinder.
In this case, the height is 9cm, and the width is 10cm. To find the radius, we divide the width by 2:
r = 10cm / 2 = 5cm
Now we can plug in the values into the formula:
V = πr^2h
V = π(5cm)^2(9cm)
V = π(25cm^2)(9cm)
V = 225π cm^3
So the volume of the cylinder is 225π cm^3
