Step-by-step explanation:

Rectangle has its adjacent sides perpendicular to each other. The lengths of the sides of the considered rectangle are: 5 inches and 12 inches.

Its the sum of length of the sides used to made the given figure.

For a rectangle, as the rectangle has two of its sides equal to its length, and rest two are equal to its width, thus,

perimeter of rectangle = twice of (width + length)

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]  

where |AB| = length of line segment AB.

In a rectangle, its adjacent sides are perpendicular to each other(making 90 degrees with each other), thus, when its diagonal is drawn, we can use Pythagoras theorem to relate its length, width and length of the diagonals (both of diagonals of a rectangle are of same length).

Thus,  using Pythagoras theorem, we get:

[tex](|Diagonal|)^2 = |Length|^2 + |Width|^2[/tex]

Suppose its length and width are L and W, then we get two equations:

Perimeter = 2(L + W) = 34 inches

Diagonal² = 13² = 169 = L² + W²

From the first equation, getting L in terms of W, we get:

[tex]L = 17 - W[/tex]

Putting this value in second equation, we get:

[tex]L^2 + W^2 = 169\\(17-W)^2 + W^2 = 169\\289 + W^2 + W^2 -34W = 169\\2W^2 -34W + 120 = 0\\W^2 - 17W + 60 = 0\\W^2 -12W - 5W + 60 = 0 \\W(W - 12) - 5(W - 12) = 0\\\\(W-5)(W-12) = 0\\W = 5, 12[/tex](in inches)

Thus, we get L= 17-W = 12 or 5,

Thus, dimensions of the considered rectangle are 5 inches and 12 inches.

A complete probability model provides a framework for calculating the likelihood of events within an experiment or a process. When we talk about a complete probability model, we are referring to a comprehensive description that includes all necessary components to understand and predict outcomes within a probability space.

Let's look at each option and determine which one correctly describes a complete probability model:

A. A list of all possible outcomes in the sample space and their probabilities.
- **This option is correct because a complete probability model does indeed require a list of all possible outcomes (the sample space) and the probability associated with each outcome.** Every outcome must be accounted for, and the sum of the probabilities of all individual outcomes must equal 1. This is because the sample space encompasses every possible outcome that could occur, and their associated probabilities reflect the likelihood of each of these outcomes.

B. The actual outcomes of a trial.
- This option is incorrect because the actual outcomes of a trial are observational results from a single execution of the probability experiment and do not represent a comprehensive model. A complete probability model is theoretical and does not depend on individual trial results, even though it can predict the distribution of those results over many trials.

C. The number of trials conducted.
- This option is incorrect. The number of trials refers to the experimental aspect of probability where an experiment or process is repeated multiple times. It does not provide a model of the entire probability space, only empirical data based on these repetitions.

D. The difference between the theoretical and experimental probabilities of all outcomes.
- This option is incorrect as it refers to the concept of variance between what is expected theoretically and what is observed in practice. While this can be a useful measure for understanding how closely an experiment follows its theoretical predictions, it is not a description of a complete probability model itself.

Given the options, the correct answer is:
A. A list of all possible outcomes in the sample space and their probabilities.

This is the definition of a complete probability model as it provides the necessary information to fully describe the probability of events within a given context.

Step-by-step explanation:

Alright, lets get started.

The total surface area of rectangular pyramid will be the area of all four faces and area of base.

The faces are triangular, so area will be = [tex]\frac{1}{2}*base*height[/tex]

Area of face = [tex]\frac{1}{2}*16*14=112[/tex]

Another face area = [tex]\frac{1}{2}*12*15=90[/tex]

Each face has its similar another face. So total area of faces will be = [tex]112+112+90+90=404[/tex]

Area of base = [tex]12*16=192[/tex]

So total surface area = [tex]404+192=596[/tex] square feet

Hence the total surface area is 596 square feet.   :   Answer

Final answer:

The radius of the circle with the equation (x − 3)² + (y − 7)² = 9 is found by taking the square root of 9, which is 3. Therefore, the correct answer is A) 3.

Explanation:

The question asks to find the radius of a circle given its equation. The standard form of the equation of a circle is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. Comparing this with the given equation (x − 3)² + (y − 7)² = 9, we see that the value of r² is 9.

Therefore, the radius r of the circle is the square root of 9, which is 3.

Hence, the correct answer is A) 3.

Answer is A because it’s moved 2 to the right which makes it x-2 and it’s moved 1 down so -1 and it needs to be -x because it’s facing down so the answer is A

Answer:

Option A. f(x) = -(x - 1)² - 1

Step-by-step explanation:

After the transformation of g(x) = x², vertex of the red parabola f(x) is (2, -1).

Therefore, equation of the parabola in the vertex form will be

f(x) = (x - 2)² - 1

Since opening of the parabola is downwards so the function will be

f(x) = - (x - 2)² - 1

This function matches with option A.

To correctly rewrite the equation 4(10+5)=6(12-2) using the distributive property, we apply the property to each term inside the parentheses. Starting with the left side, we have 4(10+5). Using the distributive property, this becomes 4(10) + 4(5) = 40 + 20 = 60. Now, let's apply the distributive property to the right side of the equation. We have 6(12-2), which becomes 6(12) - 6(2) = 72 - 12 = 60. Therefore, the equation 4(10+5)=6(12-2) can be correctly rewritten as 60=60 using the distributive property.

Step-by-step explanation:

The vertex of the quadratic equation is (-7,8).

Isolate the variable y for the equation 2x-5y=7

You get y = 2/5x-7/5

The slope we have to find is the inverse of the current slope.

So the slope for the final equation is -5/2.

Then use point slope form to get y - 8 = -5/2 * (x+7)

Then convert it into slope intercept form to get y - 8 = -5/2x - 35/2

Then add 8 to each side to get y=-5/2x-19/2

Step-by-step explanation:

The true statement is B. A rhombus is a parallelogram. This is true because rhombuses have parallel opposite sides, defining them as parallelograms. The other statements are false due to specific conditions not met by all parallelograms, rhombuses, or trapezoids.

The true statement among the options provided is B. A rhombus is a parallelogram. This is because all rhombuses have opposite sides that are parallel to each other, which is a defining property of parallelograms. Not all parallelograms are squares because a square is a special type of parallelogram where all sides are equal in length and all angles are right angles - a condition not required for a general parallelogram.

Similarly, not all rhombuses are squares since rhombuses do not require all angles to be right angles. Lastly, a trapezoid typically has only one pair of parallel sides, not two, which differentiates it from parallelograms.

To illustrate why a rhombus is a parallelogram, we can consider A1 Constructibility of parallelograms: Given any three points P, Q, and R, there exists a point S such that quadrilateral PQRS is a parallelogram. In a rhombus, all four sides are of equal length - satisfying the conditions of a parallelogram, which requires only that opposite sides be parallel and of equal length.

When it comes to the diagonals of a rhombus being perpendicular, we use the concept of the scalar or dot product of vectors. The diagonals bisect each other at right angles because the dot product of the vectors representing the diagonals equals zero, indicating that they are perpendicular to each other. This fact further underscores the relationship between rhombuses and parallelograms and their distinct geometric properties.

Answer:

1 3/8 ft.

Step-by-step explanation:

The cabinet's center will be at the same place as the wall's center. The wall's center is at its 3 1/8 ft mark. The cabinet's center will also be at the wall's 3 1/8 mark. This means that both sides of the cabinet is 1 3/4 around the center line (if my wording is vague, look at the image). So, we have to find 3 1/8 - 1 3/4, which is 1 3/8 ft.

Subtraction is one of the most basic mathematical operations. The end of the cabinet is 1.375 feet far from the edge of the wall.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The centre of the cabinet will lie at half the width of the cabinet, therefore, the centre of the cabinet will be at,

[tex]\text{Centre of the cabinet}= \dfrac{3\frac{1}{2}}{2}[/tex]

                                  [tex]\rm = \dfrac{\frac{(3 \times 2)+1}{2}}{2}\\\\=\dfrac{7}{2 \times 2} = \dfrac{7}{4} = 1.75\ feet[/tex]

Since Bobby wants the cabinet to be at the centre of the wall horizontally, we need to find the centre point of the wall as well, and then align both the centres together, therefore, the centre of the wall is at,

[tex]\text{Centre of the wall} = \dfrac{6\frac{1}{4}}{2}[/tex]

                            [tex]\rm = \dfrac{\frac{(6 \times 4)+1}{4}}{2}\\\\=\dfrac{25}{2 \times 4} = \dfrac{25}{8} = 3.125\ feet[/tex]

Now, the length between the end of the cabinet from the edge of the wall is the difference between the half the length of the wall and half the length of the cabinet, therefore, the length can be written as,

[tex]\rm Length = \text{Centre of the Wall} - \text{Centre of the Cabinet}\\[/tex]

            [tex]\rm = 3.125 - 1.75\\\\= 1.375\ feet[/tex]
