The probability of spinning yellow and having the number cube show an odd number = 1/12.

What is probability ?

probability can be defined as the ratio of number of favourable outcomes and total number of outcomes .

Given,

A game includes spinning the spinner with 6 equal sections

Then rolling a number cube with numbers 1-6.

Let the probability of spinning a yellow be x .

and the probability of having the number cube showing an odd number be y .

so,

The probability of spinning yellow and having the number cube show an odd number = x * y .

x = 1/6 .

y = 3/6

y = 1/2

So,

x*y =  1/6 * 1/2

x*y = 1/12

Hence, The probability of spinning yellow and having the number cube show an odd number = 1/12.

Then the two solutions are: x = (4 + 5.66) / 8 = 11.2075  and x = (4 - 5.66) / 8 = -0.2075

The sine approximation formula of Bhaskara I is a rational equation in one variable for computing the approximations of the trigonometric sines found by Bhaskara I (c. 600–c. 680), an Indian mathematician of the seventh century.

Indian astronomer and mathematician Bhaskara II lived in the 12th century. He created a number of the same foundations and findings that are entirely attributable to Europeans and are still very helpful in modern science and forecasts, such as a basic form of calculus.

Here we have the equation:

y = 4 × x² - 4 × x - 1

And the graph should be available (you can see it below this answer)

Now, we're seeking answers to:

4 × x²- 4 × x - 1 = 0

The two x values at which the graph of our function intersects the y = 0 line, or the x-axis, will be these solutions.

The next step is to identify the two x values where our graph crosses the x-axis.

We can estimate the solutions in the graph as follows:

x = -0.2

x = 1.2

The Bhaskara's equation can be used to determine the precise solutions, and we will discover that the solutions are provided by:

[tex]$x=\frac{-(-4)+-\sqrt{(-4)^2-4 * 4 *(-1)}}{2 * 4}=\frac{4+-\sqrt{32}}{8}=\frac{4+-5.66}{8}[/tex]

Then the two solutions are:

x = (4 + 5.66) / 8 = 11.2075

x = (4 - 5.66) / 8 = -0.2075

By graphing the system of equations, we can see that the solution of the system is (-5, -3).

Here we want to solve the following system of equations:

y = (2/5)*x - 1

2x - 3y + 1 = 0

To solve a system of equations graphically, we just need to graph both equations on the same coordinate axis, and then find the point where the two lines do intersect.

The graph of the system of equations can be seen on the image below.

Below you can see the graph of the system of equations, and you can see that the graphs intercept at the point (-5, -3)

To check if this is a solution, just replace these values in both equations and see if you get the same thing.

For the first one:

-3 = (2/5)*-5 - 1

-3 = -2 - 1

-3 = -3

And for the other line

2*-5 - 3*-3 + 1 = 0

-10 + 9 + 1 = 0

A system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."

A finite collection of equations for which we searched for the common solutions is referred to as a system of equations, also known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized. In everyday life, systems of equations are used to model issues when the unknown values may be represented by variables.

A system of equations has only one unique solution if the L.H.S. and R.H.S. of all the provided equations in the system are identical when the variable or point of intersection of the lines representing those equations is substituted.

What is the graph of a function?

The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.

The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.

-4y > -x + 12 is a linear inequality. To solve this inequality, we can start by isolating y:

y < x/4 - 3

This inequality is in slope-intercept form (y = mx + b), where the slope is m = -1/4 and the y-intercept is b = -3.

To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.

You can use x = -8, x = -4, x = 0, x = 4, x = 8 for example and find the y-values for each x, y < -8/4 -3 = -2, y < -4/4 -3 = -1, y < 0/4 -3 = -3, y < 4/4 -3 = -1 and y < 8/4 -3 = -1/2.

Then plot those points on a coordinate plane and draw the line that goes through them, and shade the half-plane that is above the line

Heron's formula is a formula used to calculate the area of a triangle when the lengths of its three sides are known.

It is named after Hero of Alexandria, a Greek mathematician and engineer who first derived this formula.

The formula states that the area of a triangle is equal to the square root of the product of the semi-perimeter (half the sum of the three sides) and the differences of the semi-perimeter and each side.

Mathematically, Heron's formula can be written as:

A = √(s(s-a)(s-b)(s-c)),

where A is the area of the triangle, s is the semi-perimeter and a, b, c are the length of the three sides of the triangle.

For example, if the lengths of the three sides of a triangle are 5 cm, 6 cm and 7 cm, then the semi-perimeter (s) is (5 + 6 + 7)/2 = 9 cm.

Using Heron's formula, the area of the triangle is:

A = √(9(9-5)(9-6)(9-7)) = √(9*4*3*2) = √432 = 6.48 cm2

Let L, A, and W represent the length, area, and width of the rectangular field respectively.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

Based on the data given we have,

Answer: yes

Step-by-step explanation:

(A) To find x, we can use the fact that the measures of the angles in a triangle must add up to 180 degrees. So we can write an equation using that information and the measures of angles q and r:

m angle q + m angle r + 90 = 180

(3x+25) + (4x+30) + 90 = 180

so:

7x+45 = 90

7x = 45

x = 45/7 = 5

(B) To find the degree measure of each angle, we can substitute x = 5 back into the expressions for angles q and r.

m angle q = (3x+25) = (3*5+25) = 40 degrees

m angle r = (4x+30) = (4*5+30) = 50 degrees

Since the angle p is a right angle, it has a degree measure of 90 degrees.

So the angle measures are: angle q = 40 degrees, angle r = 50 degrees, angle p = 90 degrees.

The solutions for the following equations are:

1. 2x + 1 = 7, x = 3

2. 4x + 7 = 11, x = 1

3. 2x - 3 = 7, x = 5

4. x + 3 = 4, x = 1

5. 3x - 11 = 19, x = 10

1. 2x + 1 = 7

2x = 7 - 1 = 6

2x = 6

divide both sides by 2

x = 6/2, x = 3

2. 4x + 7 = 11

= 4x = 11 - 7

= 4x = 4

divide both sides by 4

x = 4/4, x = 1

3. 2x - 3 = 7

= 2x = 7 + 3

= 2x = 10

divide both sides by 2

x = 10/2, x = 5

4. x + 3 = 4

= x = 4 - 3

x = 1

5. 3x - 11 = 19

3x = 19 + 11

3x = 30
