Answer:

Here are the probabilities for each event when a card is chosen at random from the set of cards:

Probability of choosing a yellow card:

There are 15 yellow cards out of a total of 15 + 10 + 10 = 35 cards in the set. So, the probability of choosing a yellow card is 15/35 or approximately 0.4286, which can be expressed as a fraction as 15/35.

Probability of choosing a green card:

There are 10 green cards out of a total of 15 + 10 + 10 = 35 cards in the set. So, the probability of choosing a green card is 10/35 or approximately 0.2857, which can be expressed as a fraction as 10/35.

Probability of choosing a blue card:

There are 10 blue cards out of a total of 15 + 10 + 10 = 35 cards in the set. So, the probability of choosing a blue card is 10/35 or approximately 0.2857, which can be expressed as a fraction as 10/35.

Please note that these probabilities assume that each card has an equal chance of being chosen at random, and that the total number of cards in the set remains the same throughout the process of random selection.

The table that identifies the one-sided and two-sided limits of function f at x = 2 is table A.

It should be.noted that to graph this piecewise function, follow these steps:

Plot the two given points: open circle (2, 4) and closed circle (2, 1).

Draw a smooth curve that starts at the open circle (2, 4) and curves down toward the x-axis in quadrant 2. This is the curve part of the piecewise function.

Draw a straight line that starts at the closed circle (2, 1) and passes through the point (3, -2). This is the line part of the piecewise function.

The two parts of the piecewise function meet at the point (2, 0), which is where the curve intersects the x-axis. Mark this point with an open circle to indicate that it is not included in the function.

Shade in the region above the curve and to the left of the line, since those are the parts of the plane where the function is defined. The correct option is A.

Answer:

To find the twelfth term in a geometric sequence with the first term a1 and common ratio r, we use the formula:

an = a1 * r^(n-1)

In this case, a1 = 2 and r = -1. We want to find the twelfth term, so n = 12. Substituting these values into the formula, we get:

a12 = 2 * (-1)^(12-1)

a12 = 2 * (-1)^11

a12 = 2 * (-1)

a12 = -2

Therefore, the twelfth term in the geometric sequence with a first term of 2 and a common ratio of -1 is -2.

The twelfth term in the given geometric sequence, with a first term of 2 and a common ratio of -1, is 2 as per the formula of a geometric sequence.

The twelfth term in a geometric sequence can be found using the formula of a geometric sequence, an = a1 * r^(n-1), where a1 is the first term, r is the common ratio, and n is the term number. Here, a1=2, r=-1, and n=12.

Applying these values into the formula, the twelfth term (a12) would therefore be calculated as follows: a12 = 2 * (-1)^(12-1), which simplifies to 2*(1) = 2. So the twelfth term of the given geometric sequence -2.

The graph of the function y=x²- 4x + 5 is attached accordingly. See it's features below.

The features of the function y = x² - 4x + 5 if graphed are:

Opens: The coefficient of the x² term is positive, so the graph opens upwards.

Vertex: To find the vertex, we can use the formula x = -b / (2a) where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = -4, so x = -(-4) / (2*1) = 2. Substituting x = 2 into the equation gives y = 1, so the vertex is at (2, 1).

Axis of Symmetry: The axis of symmetry is a vertical line that passes through the vertex. In this case, the axis of symmetry is x = 2.

Circle Max or Min value: Since the graph opens upwards, the vertex is a minimum point. The minimum value of the function is y = 1.

Y-intercept: To find the y-intercept, we can set x = 0 in the equation. This gives y = 5, so the y-intercept is (0, 5).

Zeroes (x-intercepts): To find the x-intercepts, we can set y = 0 in the equation and solve for x. This gives x² - 4x + 5 = 0, which can be factored as (x - 2)² + 1 = 0. Since (x - 2)² is always non-negative, the equation has no real roots, and the graph does not intersect the x-axis.

Increasing interval: The function is increasing to the left of the vertex and decreasing to the right of the vertex. The increasing interval is (-∞, 2).

Decreasing interval: The decreasing interval is (2, ∞).

Average Rate of Change: The average rate of change between any two points on the graph is equal to the slope of the secant line that passes through the two points. The slope of a secant line between two points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1).

An angle with its vertex in the middle of the circle it creates with its two radii is said to be central.

Here in the question,

As per the central angle theorem:

(2x -30) ° + x° = 180°

⇒ 2x - 30 + x = 180

⇒ 3x - 30 = 180

Adding 30 on both sides:

⇒ 3x = 180 + 30

⇒ 3x = 210

Dividing both sides by 3.

⇒ x = 70°

Now BC = 2x-30

= 2 × 70 -30

C = 2πr = 2π(8) ≈ 50.27 inches

Rounding to the nearest hundredth:

A ≈ 201.06 square inches

C ≈ 50.27 inches

Therefore, the area is approximately 201.06 square inches and the circumference is approximately 50.27 inches.

A circle with a diameter of 20 meters has a radius of 10 meters. The area and circumference are given by:

A = πr² = π(10²) ≈ 314.16 square meters

C = 2πr = 2π(10) ≈ 62.83 meters

Rounding to the nearest hundredth:

No, the sides of a triangle cannot have lengths 7, 15, and 20.

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry. A triangle is defined by its three sides and the three angles formed by those sides. The sum of the three angles in a triangle is always 180 degrees.

No, the sides of a triangle cannot have lengths 7, 15, and 20.

This is because of the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side.

In this case, if we add the two smaller sides, 7 and 15, we get 22, which is less than the length of the longest side, 20. Therefore, it is impossible to form a triangle with these side lengths.

What is slope?

In mathematics, slope refers to the steepness or incline of a line on a graph.

Let's say that the amount of green chilies used is represented by "x" (in cups), and the amount of sauce Renita can make is represented by "y" (in cups). Then, the equation of the line that represents this relationship is:

y = mx + b

where "m" is the slope of the line (which represents the amount of sauce Renita can make per cup of green chilies used), and "b" is the y-intercept of the line (which represents the amount of sauce Renita can make when she uses 0 cups of green chilies).

To find the values of "m" and "b", we need two points on the line. Let's say that Renita can make 2 cups of sauce when she uses 1 cup of green chilies, and she can make 4 cups of sauce when she uses 2 cups of green chilies. Then, we have the following two points:

(1, 2) and (2, 4)

Using these points, we can find the slope "m" of the line:

m = (y2 - y1) / (x2 - x1)

= (4 - 2) / (2 - 1)

= 2

Now, we can use one of the points to find the y-intercept "b":

y = mx + b

The area of the region is 17/6 square units.

How to calculate the area

To sketch the region between y = x²+x-2 and the x-axis over the interval [-5, 5], we first need to find the x-intercepts and the vertex of the parabola.

To find the x-intercepts, we set y = 0 and solve for x:

x² + x - 2 = 0

Using the quadratic formula, we get:

x = (-1 ± √(1 + 8)) / 2

x = (-1 ± 3) / 2

So the x-intercepts are (-2, 0) and (1, 0).

To find the vertex, we use the formula:

x = -b / 2a

where a = 1 and b = 1. So the x-coordinate of the vertex is:

x = -1 / (2*1) = -1/2

To find the y-coordinate of the vertex, we substitute this value of x into the equation:

y = (-1/2)² + (-1/2) - 2 = -9/4

So the vertex is at (-1/2, -9/4).

The region is bound by the x-axis, the vertical line x = -2, the parabola y = x²+x-2, and the horizontal line y = 0.

To find the area of the region, we need to integrate the function y = x²+x-2 over the interval [-2, 1].

∫[-2,1] (x²+x-2) dx = [x³/3 + x²/2 - 2x]_(-2,1)

= [(1/3 + 1/2 - 2) - (-8/3 + 2 - 4)]

= 17/6

The value of 'Y' and Angle A = y - 5 = 60 degrees and value of 'X' = 97 and angle B = x + 3 = 100 degrees.

A quadrilateral is a geometric shape that consists of four straight sides connected end to end to form a closed figure. The term "quadrilateral" comes from the Latin words "quadri" (meaning "four") and "latus" (meaning "side").

Quadrilaterals come in a variety of shapes and sizes, including rectangles, squares, parallelograms, trapezoids, and kites. They can be classified based on their properties, such as the length and angles of their sides, the degree of symmetry, and the presence or absence of parallel sides.

In a quadrilateral, the sum of all angles is 360 degrees. Therefore, we can use this fact to find the measures of angles A and B. We have:

Angle A + Angle B + Angle C + Angle D = 360°

Substituting the given values, we get:

[tex](y - 5) + (x + 3) + 120 + 80 = 360[/tex]

Simplifying and solving for x and y, we get:

[tex]x + y -2 = 360-200\\x + y = 162[/tex]

Therefore, we have one equation in two unknowns. We need another equation to solve for x and y. To find this equation, we can use the fact that the sum of opposite angles in a quadrilateral is 180 degrees. Therefore, we have:

∠ A + ∠ C = 180

∠ B + ∠ D = 180

Substituting the given values, we get:

(y - 5) + 120 = 180

(x + 3) + 80 = 180

Simplifying and solving for x and y, we get:

y = 65

x = 97

Therefore, angle A = y - 5 = 60 degrees and angle B = x + 3 = 100 degrees.
