Answer:

Part A

The addition equation that gives Amber's total running time is presented as follows;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr

Part B

Amber's total running time = 5/6 hr = 50 minutes

Step-by-step explanation:

Part A

The given parameters are;

The time duration Amber first ran = 10 min = 1/6 hr

The time duration Amber walks in between = 5 min = 1/12 hr

The increase in the number of minutes Amber runs in subsequent times = 5 min = 1/12 hr

Therefore, the Amber's total time is given as follows;

1/6 hr + 1/12 hr + (1/6 + 1/12) hr + 1/12 hr + x hr = 1 hr

7/12 hr + x hr = 1 hr

x hr = 1 hr - 7/12 hr  = 5/12 hr

x = 5/12

Therefore, her total running time is given by the following addition equation;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr

Part B

Therefore her total running time is given as follows;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr = 5/6 hr = 50 minutes

To find the general solution of the given system using substitution, we need to solve for one variable in terms of the other in one of the equations, and then substitute that expression into the other equation. In this case, we can solve the second equation for x1 in terms of x2, which gives us x1 = (3/2)x2. We can then substitute this expression for x1 into the first equation, which becomes x'2 = 9x2 - 18x2 = -9x2. Thus, we have the system x1 = (3/2)x2, x2 = Ce^(-9t), where C is a constant of integration. This is the general solution to the system.

The process of substitution involves solving for one variable in terms of the other in one of the equations, and then substituting that expression into the other equation. This allows us to reduce the system to a single equation in one variable, which we can then solve to find the general solution.

The general solution of the given system using substitution is x1 = (3/2)x2, x2 = Ce^(-9t), where C is a constant of integration. This solution shows the relationship between the two variables and how they change over time. The process of substitution is a useful tool for solving systems of linear differential equations and can be applied to more complex systems as well.

The number of voters that should be sampled for a confidence interval depends on the desired level of confidence and the margin of error.

A larger sample size generally leads to a smaller margin of error and a higher level of confidence in the accuracy of the results. However, the relationship between sample size and margin of error is not linear, meaning that doubling the sample size will not necessarily halve the margin of error.
To calculate the required sample size, a formula can be used that takes into account the margin of error, level of confidence, and population size.
the number of voters that should be sampled for a confidence interval depends on several factors and cannot be determined without more information.
To determine the required sample size, you can use the following formula:
n = (Z^2 * p * (1-p)) / E^2

Where:
- n is the sample size
- Z is the Z-score (usually 1.96 for a 95% confidence interval)
- p is the estimated proportion of the population (usually 0.5 for the worst-case scenario)
- E is the margin of error (in decimal form)

Hence, without the specific margin of error, we cannot provide the exact sample size needed.

You have the following equation:

(6²)ˣ = 1

In order to determine what is the possible value of x, you consider the following expression:

a⁰ = 1

which means that any number exponentiated to zero equals to 1.

Then, in the given equation (6²)ˣ = 1, you can conclude that x must be equal to zero because it is the only way that the equation has a valid solution. In fact:

(6²)⁰ = 1

Hence, x = 0

In the second case, that is, for (6⁰)ˣ = 1, you take into account that the exponent must be multiplied. Thus, you have 6⁰ˣ = 1. Any number multiplied by 0 equals 0. Then, the solution for this equation are all real numbers.

The friend is correct. Split the 2D figure as indicated in the diagram below. The rectangle on the left rotates to form the cylinder. The triangle rotates to form the cone. Think of these as like a revolving door that carves out a 3D shape. Or you could think of propellers.

The eigenvalues and eigenvectors of a Markov matrix are important in understanding the long-term behavior of a system. Let's first find the eigenvalues and eigenvectors of the given Markov matrices.

For matrix A, the characteristic equation is:

|λI - A| = 0

where I is the identity matrix. Solving for λ, we get:

(λ - 1)(λ - 0.5)(λ + 0.5) = 0

So the eigenvalues are λ1 = 1, λ2 = 0.5, and λ3 = -0.5.

Next, we can find the eigenvectors associated with each eigenvalue by solving the system of equations:

(A - λI)x = 0

For λ1 = 1, we have:

A - I =

[0.5 0.2 0.3]

[0.1 0.7 0.2]

[0.2 0.1 0.7]

Reducing to row echelon form, we get:

[1 0.4 0.6]

[0 1 -0.2857]

[0 0 0 ]

So the eigenvector associated with λ1 is:

[0.6]

[-0.2857]

[1 ]

Similarly, for λ2 = 0.5, we get the eigenvector:

[1]

[-1]

[0]

And for λ3 = -0.5, we get the eigenvector:

[-0.6]

[-0.5714]

[1 ]

For matrix A_00, the process is the same. The eigenvalues are λ1 = 1, λ2 = 0.6, and λ3 = 0.3. The corresponding eigenvectors are:

λ1: [0.6, -0.4, 0.7]

λ2: [0.8, 0.5, -0.3]

λ3: [-0.1, -0.75, -0.65]

Now, let's consider why A_100 is close to A_00. We can use the fact that A_100 = A^n, where n is the number of transitions in the Markov process. As n gets larger, the behavior of the system approaches the steady state, which is represented by the eigenvector associated with the eigenvalue of 1.

Since the eigenvalue of 1 is common to both A and A_00, we can see that the long-term behavior of both systems is governed by the same eigenvector. Therefore, as n gets larger, the difference between A_100 and A_00 becomes smaller, and the systems approach the same steady state behavior.

(im not the best at explaining, so sorry if i dont explain it well, but ill try!)

so rounding a number to a certain amount of sig figs is a pretty easy concept to grasp, in my opinion.

ex: lets say you need to round 231.45 to 3 sif figs.

basically what you have to do in this situation is count the digits up to you get to the 3rd digit.

check if the digit that follows it is smaller or bigger than 5 to see if the 3rd number will stay the same or has to go up a number.

for this problem the third digit is 1, and the digit that follows it is 4. but 1 is less than 4, so that means that it will stay as 1.

thus the answer would be 231.

Answer:

x = 7

Step-by-step explanation:

Since the two sides (9x - 25) of the triangle are congruent to each other, we can add them together

(9x - 25) + (9x - 25)

18x - 50

A triangle is 180 degrees when adding all three sides

So if 2 sides together equal 18x - 50 and the last side equals 104, then they should equal 180 total

18x - 50 + 104 = 180

Combine like terms

18x + 54 = 180

Subtract both sides by 54 to isolate the variable

18x + 54 - 54 = 180 - 54

18x = 126

Divide both sides by 18 to isolate the variable

18x ÷ 18 = 126 ÷ 18

x = 7

Check your work by plugging in the x value for the expression and adding all three sides to equal 180 degrees

9(7) - 25 + 9(7) - 25 + 104 = 180

Pemdas says to multiply first

63 - 25 + 63 - 25 + 104 = 180

38 + 38 + 104 = 180

76 + 104 = 180

180 = 180

The work is correct

Answer:

y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.

Step-by-step explanation:

The triangle with exterior angle x = 120° have the interior angles as: m∠A = 70, m∠B = 50, and m∠C = 60°

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

interior opposite angles are 2x° and (x + 15)°

2x + x + 15 = 120

3x + 15 = 120

3x = 120 - 15 {subtract 15 from both sides}

3x = 105

x = 105/3 {divide through by 3}

x = 35

m∠A = 2(35) = 70

m∠B = 35 + 15 = 50

m∠C = 180° - 120° {sum of angles on a straight line}

m∠C = 60°

In conclusion, the triangle with exterior angle x = 120° have the interior angles as: m∠A = 70, m∠B = 50, and m∠C = 60°.

For a taxable income of $1,80,900, the effective tax rate is 21.11%.

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

The system equations to describe situation are -:\(7s + 1b = 47 , 4s + 5b = 49\)

A system of equations is a set of equations containing two or more unknowns that are simultaneously solved. It is a mathematical way of representing two or more equations with the same set of variables. The solution set for a system of equations is the set of values that can make all the equations true. Systems of equations are commonly used to solve problems in mathematics, engineering, economics, and other fields. In order to solve a system of equations, methods such as substitution, elimination, and graphing can be used. Each of these methods has its own advantages and disadvantages.

where s represents the cost of strawberry taffy per pound and b represents the cost of banana taffy per pound.

Solving using elimination:

\(7s + 1b = 47\)

\(4s + 5b = 49\)

Subtract 4s from both equations:

\(3s + 1b = 47 - 4s\)

\(4s + 5b = 49\)
