The probability that a card drawn randomly from a standard deck of 52 cards is ed or a king = 7/13​

We know that the formula for the probability of an event is given by,

P = number of favourable outcomes / total number of possible outcomes of an event

Let us assume that event A : drawing a red card

and event B: drawing a king card

Here, sample space is a standard deck of 52 cards.

So, n(S) = 52

We know that there are 26 red cards in a standard deck of cards.

So, n(A) = 26

And there are 4 kings

So, n(B) = 4

Since there are two cards of king are red and two are black.

The favorable number of cards = 26+2

                                                 =28

So, the required probability is:

P = 28/52​

P = 7/13​

The equation for the graph will be y = 10x.

Let x be the number of T-shirts sold and y be the profit in dollars. Then, we can write the equation as:

y = (50/5)x

Simplifying the equation, we get:

y = 10x

To graph this linear equation, we can plot several points on the coordinate plane. For example, we need to plot points where x=0, y=0, x=1, y=10, x=2, y=20, and so on. We can then connect the points with a straight line to graph the equation. Check the attached document for clue.

The shaded region is below both lines, and the boundary line y = 2x - 1 is dashed because the inequality is strict. The solution can be described as: y < 5 - 3x and y < 2x - 1.

Inequality is a mathematical statement that compares two values or expressions. It uses symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to indicate the relationship between the two expressions. Inequalities are used to represent a range of possible values, rather than just a single value as in an equation.

Here,

We have the system of inequalities:

y + 3x < 5

2x - y > 1

To solve this system, we can start by isolating y in each inequality:

y < 5 - 3x

y < 2x - 1

Now we can graph each inequality on the coordinate plane and shade the region that satisfies both inequalities.

For the first inequality y < 5 - 3x, we can start by graphing the line y = 5 - 3x. This line has a y-intercept of 5 and a slope of -3. Since the inequality is y < 5 - 3x, we need to shade the region below the line.

For the second inequality y < 2x - 1, we can start by graphing the line y = 2x - 1. This line has a y-intercept of -1 and a slope of 2. Since the inequality is 2x - y > 1, we need to shade the region below the line.

The solution to the system is the region that is shaded by both inequalities. Here is a graph of the solution:

From greatest comparative advantage to least comparative advantage the list of toothpaste is Mint, Fresh, Sparkling, Bright White

To determine the comparative advantage of toothpaste companies in producing small tubes of toothpaste, we need to look at the opportunity cost of producing small tubes of toothpaste in terms of the production of large tubes of toothpaste. The company with the lowest opportunity cost of producing small tubes of toothpaste (i.e., the company that gives up the least amount of large tubes of toothpaste to produce small tubes of toothpaste) has the greatest comparative advantage in producing small tubes of toothpaste. We can calculate the opportunity cost by looking at the difference in the number of large tubes of toothpaste that each company could produce if they chose to produce only large tubes versus the number of large tubes they could produce if they chose to produce some small tubes as well.

So, using the data provided in the table, we can calculate the opportunity cost for each company as follows:

Sparkling:

Opportunity cost of producing small tubes of toothpaste = (200 large tubes/hour - 100 large tubes/hour) / 200 small tubes/hour = 0.5 large tubes per small tube

Bright White:

Opportunity cost of producing small tubes of toothpaste = (250 large tubes/hour - 100 large tubes/hour) / 250 small tubes/hour = 0.6 large tubes per small tube

Fresh:

Opportunity cost of producing small tubes of toothpaste = (250 large tubes/hour - 200 large tubes/hour) / 250 small tubes/hour = 0.2 large tubes per small tube

Mint:

Opportunity cost of producing small tubes of toothpaste = (150 large tubes/hour - 150 large tubes/hour) / 150 small tubes/hour = 0 large tubes per small tube

Therefore, the order of the companies from greatest comparative advantage to least comparative advantage in producing small tubes of toothpaste is: Mint, Fresh, Sparkling, Bright White

The median age of the remaining students in Professor Melendez's college algebra class is 18.5.

To find the median age of the remaining students in Professor Melendez's college algebra class, we need to first remove the outliers, which are the ages of 27 and 47. After removing these outliers, we are left with 8 ages: 19, 18, 18, 18, 7, 19, 20, and 18. To find the median age, we need to arrange the ages in order from least to greatest. The ordered list of ages is: 7, 18, 18, 18, 19, 19, 20. Since there are an even number of ages, we need to find the average of the middle two ages, which are 18 and 19.

What is transformation?

On a coordinate plane, forms can be translated, rotated, and reflected thanks to transformations. Any line, any point, and any vector can be reflected, rotated, and translated.

We are given coordinates of triangle ABC as A (1, -3), B (3, 0) and C (4, -2).

Now, we need to rotate the triangle 180 degrees about the origin.

We know that the rotation rule for rotating 180 degrees about the origin is that (x, y) becomes (-x, -y).

So, we get the new coordinates as

A' (-1, 3)

B' (-3, 0)

C' (-4, 2)

Now, on reflecting it over the y - axis, we get

A' (1, 3)

B' (3, 0)

C' (4, 2)

================================================

Explanation:

Inscribed angles w and s subtend the same arc that the inscribed angle 31 degrees is doing. Therefore, angle w = angle s = 31 degrees.

Inscribed angles that subtend the same arc will be equal in measure.

Similarly, the 17 degree angle and angle u both subtend the same arc. This must mean angle u = 17 degrees.

------------

Use the inscribed angle theorem to determine the central angle t

angle t = 2*(inscribed angle w)

angle t = 2*(31)

angle t = 62 degrees

The water level is rising at a rate of 0.1 cm/min when the water is 50 cm deep

Let's begin by finding the volume of water in the trough when the water is 50 cm deep. We know that the trough has an isosceles trapezoid cross-section, so we can find the area of the cross-section using the formula for the area of a trapezoid

A = ((b1 + b2)/2) × h

where b1 and b2 are the lengths of the parallel sides of the trapezoid, and h is the height of the trapezoid.

In this case, b1 = 20 cm, b2 = 80 cm, and h = 60 cm. So the area of the cross-section is

A = ((20 + 80)/2) × 60

A = 3000 cm^2

To find the volume of water in the trough when the water is 50 cm deep, we need to multiply the cross-sectional area by the length of the trough and the depth of the water

V = A × L × d

V = 3000 cm^2 × 10 m × 0.5 m

V = 15000 L

Now that we know the volume of water in the trough, we can find how fast the water level is rising by taking the derivative of the volume with respect to time

dV/dt = 0.3 m^3/min

We need to convert this rate to units of L/min, so we can multiply by 1000 to convert m^3 to L

dV/dt = 0.3 m^3/min × 1000 L/m^3

dV/dt = 300 L/min

Finally, we can use the formula

dV/dt = A × dh/dt

to find how fast the water level is rising when the water is 50 cm deep. We know A = 3000 cm^2, and we want to find dh/dt when d = 50 cm. We can rearrange the formula to solve for dh/dt

dh/dt = dV/dt / A

dh/dt = 300 L/min / 3000 cm^2

dh/dt = 0.1 cm/min

A rate is a measure of the amount of change of one quantity with respect to another quantity, often expressed as a ratio or a fraction. It tells us how much one quantity changes per unit of time or per unit of another quantity. Examples of rates include speed, velocity, acceleration, interest rate, and growth rate

In the given table, the independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$".

The relationship between the number of snacks purchased and the total cost is a linear relationship, where the total cost increases by $3 for every additional snack purchased.

We can write the equation for the relationship between the two variables as:

$ = 3s + 15

Here, the constant term 15 represents the fixed cost or the cost of buying zero snacks. The coefficient 3 of the independent variable "s" represents the additional cost incurred for each additional snack purchased.

Step-by-step explanation:

Given an initial ratio of boys : girls = 6 : 5 that becomes 1 : 1 when 3 boys leave the room, you want to know the number of girls in the room.

The initial difference in the number of ratio units is 6 -5 = 1. Removing 1 ratio unit from the "boys" side makes the ratio 5 : 5 = 1 : 1.

So, that 1 ratio unit corresponds to 3 boys. There are 5 ratio units of girls, so 3·5 = 15 girls.

There are 15 girls (Y) in the room.

__

Alternative solution

You could write an equation or two:

  b/g = 6/5 . . . . . . initial ratio of boys/girls

  (b-3)/g = 1/1 . . . . final ratio of boys/girls

Solving the first for b gives

  b = 6/5g

Using that in the second gives ...

  (6/5g -3) = g . . . . . . substitute for b, multiply by g

  1/5g = 3 . . . . . . . . add 3-g

  g = 15 . . . . . . . multiply by 5

Define coordinates of a triangle?

A location on the plane that is defined by an ordered pair of numbers is called a coordinate in a triangle (x,y). The y-coordinate and x-coordinate of a point indicate its vertical and horizontal positions, respectively.

Triangles can be described using a variety of coordinate systems in the Euclidean plane. Triangular coordinates is a name for one of these systems. It is a particular instance of barycentric coordinates for a triangle, and in that case it is sometimes referred to as a ternary plot or as areal coordinates

A barycentric coordinate system in geometry is a coordinate system where a point's location is determined by reference to a simplex (a triangle for points in a plane, a tetrahedron for points in three-dimensional space, etc.) . A point's barycentric coordinates can be thought of as the center of mass (or barycenter) of masses that are positioned at the vertices of a simplex. These masses can all be positive or negative, but only if the point is contained within the simplex.

Many branches of mathematics and physics, such as computer graphics, finite element analysis, and fluid dynamics, make use of barycentric coordinates.

So,(AC + AD) = x + (x + 50) = 2x + 50 metersNow we can use the value of AC / (AD + 50) in equation (3) and solve for AB.AB = AC tan(17°) = (2x + 50) tan(17°) tan(31°) / (tan(31°) - tan(17°))Substitute the value of AB from equation (1), so;AC tan(17°) = (2x + 50) tan(17°) tan(31°) / (tan(31°) - tan(17°))AC = (2x + 50) tan(31°) / (tan(31°) - tan(17°))Now, let's use the value of AC in equation (1),AB = AC tan(17°) = (2x + 50) tan(17°) tan(31°) / (tan(31°) - tan(17°)) = 102.86 meters (approx.)So, the height of the building is AB = 102.86 meters (approx.)
