The event containing the outcomes belonging to a or b or both is the union of a and b.

Let us consider two sets a and b, and say events or the elements in set a are: (x, y, z), and the elements in set b are: (o, p, q)

The union of these two sets will give:

aUb=(x, y, z, o, p, q)

Now, a union of two sets (denoted by U), for our case a and b, is the set or event containing the elements belonging to a or b or both the elements in a and b altogether.

Thus, the even containing the outcomes belonging to a or b or both in a and b altogether is the union of a and b.

Step-by-step explanation: Each game is $25.50 which in math means it has an "x"

So if x=1 then 25.50x says that 1 video game is $25.50

Set up the equation:

200 = 25.50x (divide both sides by 25.50 to isolate the x)

200/25.50 = 7.84

x = 7.84

You can't have 0.84 of a video game, so Roberto can only buy 7 of them.   The answer is correct good job!

Answer:

\(\overline{AC} \cong \overline{BC}\)

"line segment AC is congruent to line segment BC"

Step-by-step explanation:

First, establish that the two triangles \(\triangle ADC\) and \(\triangle BDC\) are congruent.

The triangles share side \(\overline{CD}\), and through the reflexive property of congruence, we know that any line segment is congruent to itself.

Angles \(\angle ADC\) and \(\angle BDC\) are congruent because they are supplementary, and \(\angle BDC\) is a right angle, or its measure is 90°; therefore the other angle must also be 90°, and angles with the same measure are congruent.

It is given that \(\overline{AD}\) and \(\overline{BD}\) are congruent.

Now, it can be proven that \(\triangle ADC\) and \(\triangle BDC\) are congruent using the SAS theorem.

Finally, \(\overline{AC}\) is congruent to \(\overline{BC}\), or \(\overline{AC} \cong \overline{BC}\), because of the Corresponding Parts of Congruent Triangles are Congruent theorem (CPCTC).

Step-by-step explanation:

There are  19+ 28 + 21 + 29 = 97 balls total

  19 + 21 = 40  are red or blue

      40 out of 97    is   40 / 97 chance of red or blue

The measure of angle 1 is 50 degrees

The measure of angle 2 is 40 degrees

The measure of angle 3 is 40 degrees

The measure of angle 4 is  100 degrees

The measure of angle 5 is 40 degrees

The shapes formed are triangles. A triangle is a three-sided polygon. The sum of the angles is a triangle is 180 degree. A right triangle is a triangle in which one of its angle measure 90 degrees. An isosceles triangle has two opposite sides of equal lengths and equal angles.

1 = 180 - 130 = 50 degrees (this is because angle on a straight line is equal to 180 degrees)

2 = 180 - 90 - 50 = 40 degrees (this is because sum of angles in a triagnle is equal)

3 = 40 degrees ( this is because alternate angles are equal)

5 = 40 degrees ( this is because the triangle is an isosceles triangle)

4 = 180 - 40 - 40 = 100 degrees

The partial derivative diffusivity equation for spherical flow is ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t, and for hemispherical flow, it is the same equation.

1. The partial derivative diffusivity equation for spherical flow is derived from the spherical coordinate system and applies to radial flow in a spherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

2. The partial derivative diffusivity equation for hemispherical flow is derived from the hemispherical coordinate system and applies to radial flow in a hemispherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

1. For the derivation of the partial derivative diffusivity equation for spherical flow, we consider a spherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the polar angle (φ). By assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in spherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

2. Similarly, for the derivation of the partial derivative diffusivity equation for hemispherical flow, we consider a hemispherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the elevation angle (ε). Again, assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in hemispherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

In both cases, the term ϕμC/k ∂p/∂t represents the source or sink term, where ϕ is the porosity, μ is the fluid viscosity, C is the compressibility, k is the permeability, and ∂p/∂t is the change in pressure over time.

These equations are commonly used in fluid mechanics and petroleum engineering to describe radial flow behavior in spherical and hemispherical geometries, respectively.

To determine which differential equation(s) are linear, we need to examine the form of each equation. A linear differential equation is one that can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x), b(x), c(x), and g(x) are functions of x.

The differential equation 2xy" - 5xy' + y = sin(3x) is linear. It can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x) = 2x, b(x) = -5x, c(x) = 1, and g(x) = sin(3x).
The differential equation (v)² + xy = In(x) is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (v)², where v represents the derivative of y with respect to x. This term does not have a linear coefficient.
The differential equation y' + sin(y) = e^(3x) is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = sin(y), and g(x) = e^(3x).

The circulation integral of F around the given circle is 2π. To compute the circulation integral using the tangential vector form of Green's Theorem, we first need to parameterize the circle C.

The given circle has the equation x^2 + y^2 = 1, which can be parameterized as follows:

x = cos(t)

y = sin(t)

where t is the parameter ranging from 0 to 2π.

Next, we compute the tangential vector for the parameterization:

r(t) = cos(t)i + sin(t)j

Taking the derivative of r(t) with respect to t, we get:

r'(t) = -sin(t)i + cos(t)j

Now, we can compute the circulation integral using the formula:

∮C F · dr = ∫(F · T) ds

where F is the given vector field, T is the tangential vector, and ds is the differential arc length.

Plugging in the values, we have:

F · T = (-1 yi + 1 xj) · (-sin(t)i + cos(t)j) = -sin(t)y + cos(t)x

ds = ||r'(t)|| dt = dt

Now, we integrate over the parameter t from 0 to 2π:

∫[0 to 2π] (-sin(t)y + cos(t)x) dt

= ∫[0 to 2π] (-sin(t)sin(t) + cos(t)cos(t)) dt

= ∫[0 to 2π] (-sin^2(t) + cos^2(t)) dt

= ∫[0 to 2π] (1) dt

= [t] from 0 to 2π

= 2π

Therefore, the circulation integral of F around the given circle is 2π.

Therefore, the measure of the central angle whose radii define the given arc is approximately 83.077 degrees.

The length of an arc on a circle is given by the formula:

Arc Length = (Central Angle / 360°) * Circumference

In this case, we know the arc length is 6π centimeters, and the radius of the circle is 13 centimeters. The circumference of the circle can be calculated using the formula:

Circumference = 2π * Radius

Substituting the radius value, we get:

Circumference = 2π * 13

= 26π

Now we can use the arc length formula to find the central angle:

6π = (Central Angle / 360°) * 26π

Dividing both sides of the equation by 26π:

6π / 26π = Central Angle / 360°

Simplifying:

6 / 26 = Central Angle / 360°

Cross-multiplying:

360° * 6 = 26 * Central Angle

2160° = 26 * Central Angle

Dividing both sides by 26:

2160° / 26 = Central Angle

The standard deviation of a sample proportion is given by the formula:

σ = sqrt((p * (1 - p)) / n)

where σ is the standard deviation, p is the sample proportion, and n is the sample size.

If we want the standard deviation to be one-half of what it was for a sample of size 100, we can write the following equation:

(sqrt((p * (1 - p)) / n)) / 2 = sqrt((p * (1 - p)) / 100)

To simplify the equation, we can square both sides:

((p * (1 - p)) / n^2) / 4 = (p * (1 - p)) / 100

Simplifying further:

100 * n^2 = 4 * 1

n^2 = (4 * 1) / 100

n^2 = 0.04

Taking the square root of both sides:

n = sqrt(0.04)

n = 0.2

Therefore, the sample size should be 0.2. However, since the sample size must be a positive integer, we round it up to the nearest whole number. Therefore, the sample size should be 1.
