The cost of labor, per hour, will be equal to $125.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tristan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged him $50 for parts.

The cost for labor per hour is,

TC = 50 + 4.75x

643.75 = 50 + 4.75x

x = ( 643.75 - 50) / 4.75

x = $125

Therefore, the cost of labor, per hour, will be equal to $125.

Answer:

Step-by-step explanation:

f(x) = x + 7

g(x) = x^2 - 1

Part A: f(x^2 - 1) = x^2 - 1 + 7 = x^2 + 6

Part B: g(x+7) = (x + 7)^2 - 1 = x^2 + 14x + 49 - 1 = x^2 + 14x + 48

The value of the test statistic for the one-sample t-test, given a sample size of 16, sample mean of 5.7, sample standard deviation of 1.3, and a testing mean of 6.1, can be calculated using the formula for the t-test statistic.

To calculate the test statistic for a one-sample t-test, we use the formula:

t = (sample mean - testing mean) / (sample standard deviation / √sample size)

Plugging in the given values:

t = (5.7 - 6.1) / (1.3 / √16)

Simplifying the equation:

t = (-0.4) / (1.3 / 4)

t = (-0.4) / (0.325)

t = -1.23

Therefore, the value of the test statistic for the given scenario is -1.23. The test statistic represents the number of standard errors the sample mean is away from the testing mean, and it is used to assess the likelihood of obtaining the observed sample mean under the null hypothesis. In this case, a negative test statistic indicates that the sample mean is lower than the testing mean.

The prime factorization of the radicand 2 is 9√15.

A number can be expressed as the product of its prime components through the process of prime factorization. A number with precisely two elements, 1 and the number itself, is said to be a prime number.

As an illustration, let's use the number 30. We know that 30 = 5 × 6, but 6 is not a prime number. The number 6 can further be factorized as 2 × 3, where 2 and 3 are prime numbers. Therefore, the prime factorization of 30 = 2 × 3 × 5, where all the factors are prime numbers.

Given that,

x= 3√135

Solving the equation further using the rule √A*B = √A*√B

x= 3√9*15

x= 3√9*√15

x=3*3*√15

x= 9√15

Therefore, the prime factorization of the radicand 2 is 9√15.

Step-by-step explanation:

Triangle Area formula: bh/2

Plug it in: (7.4)(4.5)/2=16.65

Perimeter: Add the sides

12.6+7.4+6.3=26.3

Answer:

Step-by-step explanation:

Remark

Here are the formulas for what you are asking for.

P = s1 + s2 + s3

Area = height * base / 2

Givens

s1 = 12.6

s2 = 6.3

s3 = 7.4

height = 4.5

base = 7.4

The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended.  See the givens for what that is.

Solution

Perimeter

P = s1 + s2 + s3                        Substitute givens into the formula

P = 12.6+6.3 + 7.4

p = 26.3

Area

Area = (B * H)/ 2

Area = 7.4 *4.5 / 2

Area = 16.65

The length of wire fence required to enclose the garden is 52 feet.

We have to determine the length of wire fence required to enclose a square garden of area 169 square feet.

To find the length of wire fence required, we can start by determining the side of the square garden:

Let s be the length of the side of the square garden.

Area of the garden = s²

Given that the area of the garden is 169 square feet.

s² = 169Taking square root on both sides of the above equation, we get:

s = √169=13 feet

Therefore, the garden is a square of side length 13 feet.

To enclose the garden with wire fence, we need to find the perimeter of the garden.

Perimeter of the square garden = 4s (since all sides of a square are equal)

Therefore, the length of wire fence required to enclose the garden = 4s = 4×13= 52 feet.

Hence, the length of wire fence required to enclose the garden is 52 feet.

All of these equations have two complex solutions.

Step-by-step explanation:

The two complex solutions of a given equation refer to the two distinct solutions that can be obtained when the equation is solved. In this case, the equation is a polynomial equation with degree two (also known as a quadratic equation). The two complex solutions are found by using the quadratic formula, which states that if a, b, and c are given real or complex coefficients, then the two solutions to the equation ax2 + bx + c = 0 are: x = (-b ± √(b2 - 4ac))/2a. These two values will always be complex if the discriminant, b2 - 4ac, is negative. This means that these two complex solutions represent the two different roots of the equation.

The number of degrees of freedom that should be used for finding the critical value is 5.

To determine the number of degrees of freedom, we need to understand the context of the problem and the given information. Unfortunately, the accompanying data display and the provided text are incomplete and unclear, making it difficult to fully address the question.

However, based on the information given, we can make some assumptions and provide a general explanation of degrees of freedom.

Degrees of freedom (df) refer to the number of independent pieces of information available for estimation or testing in statistical analysis. In the case of hypothesis testing or confidence intervals, degrees of freedom are crucial in determining critical values from probability distributions.

In this question, we need to find the critical value for a 96% confidence level. The critical value corresponds to a specific significance level and degrees of freedom.

The significance level is a predetermined threshold used to assess the strength of evidence against the null hypothesis. However, without complete information about the statistical test or the sample size, it is not possible to determine the exact degrees of freedom or critical value.

To determine the degrees of freedom, we need to consider the specific statistical test being used. For example, in a t-test, the degrees of freedom are calculated based on the sample size and the type of t-test (e.g., independent samples or paired samples).

In an analysis of variance (ANOVA), the degrees of freedom are calculated based on the number of groups and the sample sizes within each group. The formula for calculating degrees of freedom varies depending on the statistical test.

In conclusion, the question does not provide enough information to determine the exact number of degrees of freedom or the corresponding critical value. It is important to have complete information about the statistical test, sample size, and any other relevant details in order to accurately determine the degrees of freedom and corresponding critical value.

The solution to the system of differential equations dx/dt = [[3, 9], [-1, -3]]x with x(0) = [[2], [4]] is x = [[6cos(2t)], [2cos(2t)]].

To solve the system of differential equations dx/dt = [[3, 9], [-1, -3]]x with x(0) = [[2], [4]], we can use the eigenvalue method. The matrix [[3, 9], [-1, -3]] has eigenvalues λ₁ = 2 and λ₂ = -2, with corresponding eigenvectors v₁ = [[3], [1]] and v₂ = [[3], [-1]].

Let's denote x = [[x₁], [x₂]]. Using the eigenvectors, we can write x as a linear combination of the eigenvectors: \(\[x = c_1 \mathbf{v}_1 e^{\lambda_1 t} + c_2 \mathbf{v}_2 e^{\lambda_2 t}\]\), where c₁ and c₂ are constants to be determined.

Using the given initial condition x(0) = [[2], [4]], we have:

[[2], [4]] = c₁[[3], [1]] + c₂[[3], [-1]]

Solving this system of equations, we find c₁ = 2 and c₂ = 0.

Thus, the solution to the system of differential equations is:

\(\[x = 2 \begin{bmatrix} 3 \\ 1 \end{bmatrix} e^{2t}\]\)

In real form, we can expand the exponential term using Euler's formula: e^(2t) = cos(2t) + i sin(2t). So the solution becomes:

x = [[6cos(2t)], [2cos(2t)]]

In real form, the solution is x₁ = 6cos(2t) and x₂ = 2cos(2t).
