After considering all the given data and running a series of calculation we reach the conclusion that the probability of receiving both orders as the same colors is 0.2184, under the condition that a company has the information that 32% of their customers order their product in Black and 26% in White and 22% in Grey.

Then the evaluated probability of both orders being the same color can be found by applying summation of the probability of both orders being black, both orders being white, and both orders being grey.

Now, the probability of both orders being black is 0.32 × 0.32
= 0.1024.

Similarly the probability of both orders being white is 0.26 × 0.26
= 0.0676.

Lastly, the probability of both orders being grey is 0.22 × 0.22
= 0.0484.

Hence, the evaluated probability of both orders being the same color is 0.1024 + 0.0676 + 0.0484 = 0.2184 (rounded to four decimal places).

Selling 80 items will produce maximum profit if the profit function is [tex]P(x) = 2400x + 105x^2 - x^3 - 167,000[/tex].

To find value of x that produces maximum profit, we must get critical points of the profit function and determine which one corresponds to a maximum.

The profit function is given as:

[tex]P(x) = 2400x + 105x^2 - x^3 - 167,000[/tex]

Taking the derivative of P(x) with respect to x, we get:

[tex]P'(x) = 2400 + 210x - 3x^2[/tex]

Setting P'(x) equal to zero and solving for x, we get:

[tex]0 = 2400 + 210x - 3x^2\\3x^2 - 210x - 2400 = 0\\x^2 - 70x - 800 = 0\\(x - 80)(x + 10) = 0[/tex]

Here, the critical points are x = 80 and x = -10.

To determine one that corresponds to a maximum, we can use the second derivative test. Taking the derivative of P'(x), we get:

[tex]P''(x) = 210 - 6x[/tex]

Evaluating P''(80), we get:

[tex]P''(80) = 210 - 6(80)\\P''(80) = 210 - 420\\P''(80) = -330[/tex]

Since P''(80) is negative, the critical point x = 80 corresponds to a maximum. So, selling 80 items will produce maximum profit.

The rotation transformation of the quadrilateral IJKL, to obtain the quadrilateral I'J'K'L', are; I'(-2, 3), J'(0, -2), K'(-2, -3), L'(-3, 1)

A rotation transformation is one in which the coordinates of a geometric figure are rotated about a point.

Answer:

The surface area of the square pyramid is 18 km².

Step-by-step Explanation:

What is the surface area of a square pyramid with a slant height?

The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.

Mathematically, it can be expressed as:

Surface Area S.A = P × l/2

where;

Side length (a) = 3

Base perimeter (P) = 4a = 4(3) = 12km

Slant length (l) = 3 km

Surface Area (S.A) = 12 × (3/2)

Surface Area (S.A) = 12 x 1.5 = 18 km²

Therefore, the surface area of the same pyramid is 18 square km.

[tex]\sf SA_{Pyramid} =\boxed{\sf 27km^{2}}.[/tex]

We're asked to calculate the surface area (SA) of a pyramid. Surface area of a tridimensional shape isn't more than calculating the area of all of its "faces" and then adding them all together. Some of these tridimensional shapes already have equations that provide a direct calculation of this parameters, without the need to add together the area of the different parts of the shape.

There's a developed formula for directly calculating the surface area of square pyramids, but in this case it is easier to just calculate the individual areas of each face and add them all together.

This is pretty easy to calculate, as the base forms the shape of a square. Therefore, multiplying the length and width of this square will give us that area:

[tex]\sf A_{Base} =lw=3km*3km=\boxed{\sf 9km^{2}} .[/tex]

Check attached image 1 to see where we got these values from.

So these faces form the sape of a triangle. Therefore, mul;tiplying their lengh by width and then dividing by 2 should give us the area.

[tex]\sf A=\dfrac{lw}{2} =\dfrac{(3km)(3km)}{2}=4.5km^{2}.[/tex]

Check attached image 2 to see where we got these values from.

This is the area of an individual triangular face of the pyramid, but we have a total of 4 faces. Hence, let's multiply this area by 4 to find the total area of all triangular faces:

[tex]4.5km^{2} *4=\boxed{\sf 18km^{2}}.[/tex]

So the total surface area, as stated at the beginning of this answer, is given by the addition of all individual areas from all the faces of the shape, so let's do just that:

[tex]\sf SA_{Pyramid} =9km^{2} +18km^{2}=\boxed{\sf 27km^{2}}.[/tex]

Answer:

L * W

Step-by-step explanation:

To find the difference in volume between the original prism and the new prism, we need to calculate the volume of each prism and then subtract the volumes.

Let's assume the base of the prism is a rectangle with length L, width W, and height H.

The volume of a prism is given by V = L * W * H.

Original Prism:

Height = 3 inches

Volume = L * W * 3

New Prism:

Height = 4 inches

Volume = L * W * 4

The difference in volume between the original prism and the new prism is:

New Prism Volume - Original Prism Volume = (L * W * 4) - (L * W * 3)

= L * W * (4 - 3)

= L * W

Therefore, the difference in volume is L * W.

Since we do not have specific dimensions or values for L and W, we cannot calculate the exact difference in volume. We would need additional information to determine the values of L and W or their relationship to find the difference in volume.

The specified scalar is 12 as the result of u(v + w) is 12i + 12j.

The provided vectors are given to be u = 4i - j v = 3i + j w = i + 3j. First, we need to find the vector v + w,

v + w = (3i + j) + (i + 3j)

v + w = 4i + 4j

Now, we can find dot product, u(v + w),

u(v + w) = u(4i + 4j)

u(v + w) = 4ui + 4uj

Substituting the given values of u, we get,

u(v + w) = 4(4i - j)i + 4(4i - j)j

u(v + w) = 16i - 4j + 16j - 4i

Simplifying, we get,

u(v + w) = 12i + 12j

Therefore, the specified scalar is 12.

An equation for this linear function that describes how height varies with age is y = 1/5(x) + 2.

The predicted height at 9 is 3.8 feet.

The predicted height at 31 is 8.2 feet.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

Conversion:

1 feet = 12 inches

24 inches = 24/12 = 2 feet.

Next, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (4 - 2)/(10 - 0)

Slope (m) = 2/10

Slope (m) = 1/5

At data point (0, 2) and a slope of 1/5, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 2 = 1/5(x - 0)  

y = 1/5(x) + 2

When x = 9, the predicted height is given by;

y = 1/5(9) + 2

y = 3.8 feet.

When x = 31, the predicted height is given by;

y = 1/5(31) + 2

y = 8.2 feet.

Step-by-step explanation:

At f(2) we can notice that there is 2 y-values (one is an open circle and another is a closed circle)

But, an open circle means that the function is not defined at that point
But a closed circle means that it is defined

So we ignore the open circle and the closed circle is 3

Adding -4(row 1) to row 3 in the matrix will produce: 0, -9, 2, and 12 respectively.

A rectangular array of numbers or mathematical objects which are arranged in rows and columns is called a matrix. Each row of a matrix is a horizontal sequence of numbers or objects that are separated by commas and enclosed within square brackets, and it represents a vector in the row space of the matrix.

row 1 of the given matrix are: 1, 2, 1, and -5, multiplying -4(row1) will gives;

-4 × 1 = -4

-4 × 2 = -8

-4 × 1 = -4

Given the volume of the suitcase as 8,556 cubic inches, the length as 32 inches, and the height as 15.5 inches, we can write the equation:

8556 = 32 × w × 15.5

Simplifying this equation, we can divide both sides by the product of 32 and 15.5:

8556 ÷ (32 × 15.5) = w
