Step-by-step explanation:

Using it's concept, it is found that the probability that the person is from Texas given that the person prefers Brand b is given by:

A. 0.43.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 105 people prefer brand B, and of those, 45 are from Texas, hence:

p = 45/105 = 0.43.

Ariel's plant is 1.6 inches taller than Dyani's.

It doesn't seem that you can multiply the measurement of Dyani's plant anymore than Ariel's. So I believe that would be 0 inches.

H is E

Step-by-step explanation:

In the formula of the energy of photons "h" signifies Planck's constant.

The Planck constant, often known as Planck's constant, is a crucial physical constant in quantum physics. The mass-energy equivalency establishes the relationship between mass and frequency, and the constant establishes the relationship between a photon's energy and frequency.

In the equation energy E = h X v. The "h" there signifies Planck's constant

Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.

Therefore,  in the formula of the energy of photons "h" signifies Planck's constant.

Answer: Yes, you can use this inequality to find the numbers of cars required.

Step-by-step explanation:

12  + 3n > 28     where n = the number of cars required

3n > 28 -12

3n > 16

n > 5 1/3

Greater than 5 1/3 gives 6 cars.

Answer:

See below.

Step-by-step explanation:

12 + 3n ≥ 28

3n ≥ 16

n ≥ 5 1/3

The number of cars must be equal to or greater than 5 1/3.

Since there is no 1/3 of car, that means there must be 6 cars.

Whether the inequality is 12 + 3n > 28 with a solution of more than 5 1/5 or the inequality is 12 + 3n ≥ 28 with a solution of 5 1/3 or more, the answer is the same because the minimum number of cars that will be enough is 6.

Arithmetic sequence

Step-by-step explanation:

An list of numbers whereby the difference between each consecutive number is constant is called an arithmetic sequence. Given thelistvif numbers:

–8, –4, 0, 4, 8, 12 ;

We can see that each consecutive number in the list has a constant difference of 4. Hence x this is called an arithmetic sequence.

We obtain the values a = -4, b = 5, and c = 1. These coefficients represent the best-fit quadratic function, which is y = -4 + 5x + x².

The least squares method is used to find the best-fitting polynomial curve to a given set of data points. In this case, we are trying to find a second-degree polynomial (a quadratic function) that approximates the data points (0, -4), (2, 4), and (3, 11). By minimizing the sum of the squared errors between the polynomial and the data points, we can determine the coefficients of the quadratic function.

To solve for the coefficients, we substitute the x-values of the data points into the polynomial equation and equate it to the corresponding y-values. This results in a system of equations that can be solved to find the values of a, b, and c.

After solving the system, we obtain the values a = -4, b = 5, and c = 1. These coefficients represent the best-fit quadratic function, which is y = -4 + 5x + x². This polynomial provides the least square approximation to the given data, minimizing the overall error between the data points and the curve.

The point of diminishing returns for the revenue function R(x) occurs when the amount spent on advertising is approximately $16.9 thousand.

To find the point of diminishing returns for the revenue function R(x) = 11,000 - x^3 + 36x^2 + 700x, we need to determine the value of x at which the marginal revenue, which is the derivative of R(x), equals zero. Let's find the derivative first.

R'(x) = d/dx (11,000 - x^3 + 36x^2 + 700x)

= -3x^2 + 72x + 700

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

-3x^2 + 72x + 700 = 0

This is a quadratic equation, which can be solved using the quadratic formula. Applying the quadratic formula, we find two solutions: x ≈ -9.15 and x ≈ 26.15.

However, we are given the constraint 0 ≤ x ≤ 20, so the value of x cannot exceed 20. Therefore, we disregard the solution x ≈ 26.15.

Thus, the point of diminishing returns occurs when x is approximately 16.9 (rounded to one decimal place) thousand dollars. At this advertising expenditure, the rate of increase in revenue slows down, indicating diminishing returns.

Area of a circle is equal to \(\boldsymbol{132.8}\) square inches.

A circle is a collection of all the points that are at the fixed distance (radius) from a fixed point (center).

Radius of a circle is half of the diameter.

So,

Radius of a circle \(=\frac{13}{2}\) centimeter

Area of a circle \(=\boldsymbol{\pi r^2}\) where \(r\) denotes radius of a circle.

                         \(=\frac{22}{7}\times \left ( \frac{13}{2} \right )^{2}\\=132.7857\)

In the given right triangle, the perimeter is 12 in.

According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the length of the two legs (a and b). Hence,

c^2 = a^2 + b^2

In the given triangle,

c = x in

a = 3 in

b = 4 in

Hence,

x^2 = 3^2 + 4^2

x^2 = 9 + 16

x^2 = 25

x = √25

x = 5

The perimeter of a geometric shape is the sum of all its side. Hence,

From the given graph, the numeric values of the expressions are given as follows:

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.

On the graph of the function, the equivalent to this is that we have to find where the x-axis has the value, and find the value of y for which the function passes through the y-axis.

From the graph, when x = -1, f(x) passes the point at y = 12, hence f(-1) = 12.

For the second item, applying the same logic, we have that:

Hence:

f(1) - g(1) = 10 - 2 = 8.

For the third item, we have to look at the graph of g(x), and find the value of x when y = 4, hence g(x) = 4 when x = 2.

For the fourth item, the functions intersect at point (3,8), hence f(x) = g(x) when x = 3.

Step-by-step explanation:

In geometry, we have many formal definitions using defined words or terms. However, I can think of three words that are not formally defined. These words are point, line and plane. Even though these words are undefined we can describes them as follows:

1. Point. A point is an exact position or location in space.

It is important to understand that a point has no dimension (that is, actual size). So, it has no length, no width, and no height (thickness).

We usually named a point with a capital letter. In the coordinate plane, a point is named by an ordered pair, x,y .

Even though we represent a point with a dot, the dot can be very tiny or very large. Recall that a point has no size.

2. Line (Straight line)

A line has no thickness.

So, its length extends in one dimension.

The line extends in both directions without end (infinitely). A line has infinite length and has no width, no height.

We assume the line to be straight.

and can be drawn with arrowheads on both ends.

3. Plane

A plane is a flat surface with no thickness extending indefinitely in all directions and having two dimensions. So, it has infinite length, infinite width and has no height (thickness). Moreover, a plane is drawn as a four-sided figure resembling a parallelogram.

The representation of each concept is shown in the Figure below.

The correct triple integral in cylindrical coordinates that gives the volume of the solid bounded below by the paraboloid z = \(x^2 + y^2 - 1\)and above by the sphere \(x^2 + y^2 + z^2\)= 7 is (d) ∫∫∫ (r dz dr dθ).

Here are the limits of integration for each variable:

r: 0 to √(7 - \(z^2\))

θ: 0 to 2π

z: \(r^2\) - 1 to √3

The volume integral can be written as:

∫∫∫ (r dz dr dθ) from z = \(r^2\) - 1 to √3, θ = 0 to 2π, and r = 0 to √(7 - \(z^2\))

The limits of integration for r are determined by the equation of the sphere \(x^2 + y^2 + z^2\) = 7. Since we are in cylindrical coordinates, we have \(x^2 + y^2 = r^2\). Therefore, the expression inside the square root is 7 - \(z^2\),
