As per the given matrix, the stable distribution for the regular stochastic matrix is [tex]\begin{bmatrix}x \\y\end{bmatrix}=\begin{bmatrix}0.40 \\0.10\end{bmatrix}[/tex]

The term matrix is defined as  a set of numbers arranged in rows and columns so as to form a rectangular array.

Here we have given that the matrix is written as

[tex]\begin{bmatrix}0.5 & 0.2 \\0.5 & 0.8\end{bmatrix}[/tex]

In order to find the  stable distribution for the regular stochastic matrix, we must know what does it means in matrix.

The term  stable distribution for the regular stochastic matrix in math is defined as a square matrix whose columns are probability vectors. And the  probability vector is a numerical vector whose entries are real numbers between 0 and 1 whose sum is 1.

Here in order to find the solution, we have to equate the value with x and y and then we have to cross multiply the terms, then we get,

=> [tex]\begin{bmatrix}x \\y\end{bmatrix}=\begin{bmatrix}0.5\times0.8 \\0.2\times0.5\end{bmatrix}[/tex]

When we simplify this we get the solution as,

[tex]= > \begin{bmatrix}x \\y\end{bmatrix}=\begin{bmatrix}0.40 \\0.10\end{bmatrix}[/tex]

Answer: Let's call the hourly rate of the first mechanic "r1" and the hourly rate of the second mechanic "r2".

We know that the total time they worked is 20 hours + 5 hours = 25 hours.

We also know that the sum of their hourly rates is $95 per hour, so:

r1 + r2 = $95

We can use this information along with the total amount they charged, $1150, to find out how much each mechanic charged. We know that the total amount charged is the product of the number of hours worked and the hourly rate. So we can use the following equation:

(20 hours * r1) + (5 hours * r2) = $1150

Now we can substitute the equation r1 + r2 = $95 into the above equation and solve for r1:

(20 hours * r1) + (5 hours * (95 - r1)) = $1150

20r1 + 475 - 5r1 = 1150

15r1 = 675

r1 = $45/hour

To find out the hourly rate of the second mechanic, we can use the equation r1 + r2 = $95

r2 = $95 - r1

r2 = $95 - $45

r2 = $50/hour

So the first mechanic charges $45 per hour and the second mechanic charges $50 per hour.

the sum of the interior angles in a triangle is 180°, take away the know angle and divide by 2, it's an isosceles triangle so 2 side and 2 equal angles

(180 - 134) : 2 =                         (remember PEMDAS)

46 : 2 =

23°

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

23 + 23 + 134 = 180°

The reaction at Roller A is 1800 N and the reaction at Pin B is 2450 N. To calculate the reaction at Pin B, you need to multiply the length of the pin (3 m) by the load (450 N) and add the additional load (600 N).

Reaction at Roller A:

2 m * 900 N = 1800 N

Reaction at Pin B:

3 m * 450 N + 600 N = 2450 N

To calculate the reaction at Roller A, you need to multiply the length of the roller (2 m) by the load (900 N). This gives you 1800 N.

To calculate the reaction at Pin B, you need to multiply the length of the pin (3 m) by the load (450 N) and add the additional load (600 N). This gives you 2450 N.

Even Function

A function is "even" when:

Stated in other terms, the function graph is symmetric about the vertical(y-axis). The right part of the function graph about the y-axis is a reflection of the left part of the function graph  about the y-axis

Looking at the function graph, we see it is indeed symmetric about the y-axis

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

What is an equivalent ratios?

A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.

Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.

Given ratios are 2:1 and 3:1

we can write it as 2/1 and 3/1.

The lcm of 2 and 3 is 6.

Multiply denominator of both ratio with 6, we get

2/6 and 3/6 And we can see both the ratios are not equal.

Hence, there are not equivalent ratios.

4:1 and 8:3 are equivalent ratios -----> is false, because 4:1 is equivalent to 8:2

11:2 and 2:11 are equivalent ratios------> is false (because, are reciprocal ratios, not equivalent ratios)

The probability is 1/10.

The equation x(x+5) = -n can be rewritten as x^2 + 5x + n = 0. To find the solutions of this equation, we can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a, where a = 1, b = 5, and c = n.

For there to be no real solutions, the discriminant (b^2 - 4ac) must be negative. The discriminant is 5^2 - 4(1)(n) = 25 - 4n. So for there to be no real solutions, 25 - 4n < 0, or n > 6.25.

Since the integer n is between 1 and 10 inclusive, the only value that would not have a real solution is n = 7. Therefore, the probability that for the randomly chosen n there exist no real solutions is 1/10.

Answer:

x = 5

Step-by-step explanation:

You are solving for a x that can, when plugged in, equate both given expressions. To do so, set each given expression equal to each other:

4x - 4 = 8x - 24

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 8x and add 4 to both sides of the equation:

4x (-8x) - 4 (+4) = 8x (-8x) - 24 (+4)

4x - 8x = -24 + 4

-4x = -20

Next, divide -4 from both sides of the equation:

(-4x)/-4 = (-20)/-4

x = -20/-4

x = 5

5 is your answer.

Check:

Plug in 5 for x in both given expressions:

4x - 4

4(5) - 4

= 20 - 4

= 16

8x - 24

A percentage is a fraction or ratio in which the whole value is always 100. For instance, Sam would have received 30 out of a possible 100 points if he had received 30% on his math test. It is expressed as 30/100 in fractional form and 30:100 in ratio form.

so we put 8 and 4 in this equation:

8! / (4! *(8-4)!)

The maximum area of the rectangle is determined by the distance between the two points on the graph and the -axis.

A rectangle is a four-sided shape with four right angles and two pairs of parallel sides. It is one of the most common shapes in the world, found in everything from building designs to artwork. Rectangles are also used in math, specifically to measure area and perimeter. Rectangles can also be classified according to their sides, with squares being a special type of rectangle with four equal sides.

To calculate the maximum possible area of the rectangle, we can use the formula A = (x2 - x1)(y2 - y1).

In this case, the two points on the graph have the same -coordinate, so the x2 - x1 part of the equation is zero. This means that the y2 - y1 part of the equation gives the maximum possible area of the rectangle. To calculate this, we need to take the difference between the two points on the graph.

For example, if the two points on the graph were (2,4) and (2,6), the maximum area of the rectangle would be (6 - 4) = 2.

Therefore, the maximum possible area of the rectangle is equal to the difference between the two points on the graph.

The value of x in the expression 1 - (2/x²) = - x - 1 is  ± √2, 4.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, An expression 1 - (2/x²) = - x - 1.

- (2/x²) + x = 2.

Multiplying each term by x².

- 2 + x³ = 2x².

x³ - 2x² = 2.

x²(x - 2) = 2.

x² = 2 ⇒ x = ± √2 Or x - 2 = 2 ⇒ x = 4.
