Corrected question;

Francine has a piece of wood that is five 5/12 feet long she uses three 1/4 feet of the wood from a science project how much for just Francine have left.

Step-by-step explanation:

Given;

Francine has a piece of wood that is five 5/12 feet long.

Total amount of wood T = 5 × 5/12 ft = 25/12 ft

she uses three 1/4 feet of the wood from a science project.

Amount of wood Used U = 3 × 1/4 = 3/4 ft

The amount of wood left equals the total amount of wood minus the amount of wood used;

The amount of wood left L = T - U = 25/12 - 3/4

L = 25/12 - 9/12

L = 16/12

L = 4/3 ft

Yes, the data provides strong evidence supporting the claim that the current audience share for WXYZ is higher than last year's 25 percent share. This is indicated by the calculated test statistic (z-value) of 5.31 and the corresponding p-value of 0.000, which is less than any of the specified significance levels (0.10, 0.05, 0.01, and 0.001). Therefore, we reject the null hypothesis (H0) and conclude that there is significant evidence to support the belief that the current audience share for WXYZ is higher than 25 percent.

In the given scenario, the objective is to determine if there is evidence supporting the claim that the current audience share for WXYZ is higher than last year's 25 percent share. Here is the explanation:

(a) The null hypothesis (H0) states that the current proportion (p) of viewers watching WXYZ is less than or equal to 25 percent, while the alternative hypothesis (Ha) states that the current proportion is greater than 25 percent.

H0: p ≤ 0.25 versus Ha: p > 0.25

(b) Using the MINITAB output, we observe that the sample proportion is 0.365, and the corresponding z-value is 5.31. The p-value associated with this test is 0.000.

At the significance levels of 0.10, 0.05, 0.01, and 0.001, the evidence against the null hypothesis is extremely strong, and we reject H0 in favor of Ha.

There is substantial evidence indicating that the current audience share for WXYZ is higher than last year's 25 percent share.

(a)The range of the given set of measurements is 4.

(b)The sample mean of the given set of measurements is approximately 5.625.

(c)The sample variance of the given set of measurements is approximately 2.337768, and the sample standard deviation is approximately 1.529.

(a) The range is the difference between the largest and smallest values in the set of measurements. In this case, the largest value is 8 and the smallest value is 4, so the range is 8 - 4 = 4.

To calculate the range, we subtract the smallest value from the largest value. In this case, the largest value is 8 and the smallest value is 4.

Range = Largest value - Smallest value

Range = 8 - 4

Range = 4

The range provides a simple measure of the spread or dispersion of the data. In this case, the range tells us that the values range from the smallest value of 4 to the largest value of 8, with a difference of 4 between them.

(b) The sample mean, denoted as x, is the sum of all the measurements divided by the total number of measurements.

To calculate the sample mean, we add up all the measurements and then divide by the total number of measurements. In this case, we have 8 measurements.

Sum of measurements = 4 + 4 + 7 + 6 + 4 + 6 + 6 + 8 = 45

Sample mean = Sum of measurements / Total number of measurements

Sample mean = 45 / 8

Sample mean ≈ 5.625

The sample mean represents the average value of the measurements and provides a measure of central tendency.

(c) The sample variance, denoted as s^2, measures the variability or dispersion of the data points around the sample mean. It is calculated as the average of the squared differences between each measurement and the sample mean.

To calculate the sample variance, we first calculate the squared difference between each measurement and the sample mean. Then, we average those squared differences.

Squared difference for each measurement:

(4 - 5.625)^2 = 2.890625

(4 - 5.625)^2 = 2.890625

(7 - 5.625)^2 = 1.890625

(6 - 5.625)^2 = 0.140625

(4 - 5.625)^2 = 2.890625

(6 - 5.625)^2 = 0.140625

(6 - 5.625)^2 = 0.140625

(8 - 5.625)^2 = 5.390625

Sum of squared differences = 2.890625 + 2.890625 + 1.890625 + 0.140625 + 2.890625 + 0.140625 + 0.140625 + 5.390625 = 16.364375

Sample variance = Sum of squared differences / (Total number of measurements - 1)

Sample variance = 16.364375 / (8 - 1)

Sample variance ≈ 2.337768

The standard deviation, denoted as s, is the square root of the sample variance.

Sample standard deviation = √(Sample variance)

Sample standard deviation = √(2.337768)

Sample standard deviation ≈ 1.529

These measures provide information about the dispersion or spread of the data points around the sample mean. A higher variance or standard deviation indicates greater variability in the measurements.

The formula for converting Celsius to Fahrenheit is to multiply the Celsius temperature by 9/5 and then add 32. To convert from 37c to Fahrenheit, the calculation is 37 x 9/5 + 32 = 98.6°F.

When converting Celsius to Fahrenheit, it is important to remember the differences between the two temperature scales. Celsius is a metric unit of temperature, while Fahrenheit is a customary unit of temperature. Celsius is based on a scale in which 0°C is the freezing point of water and 100°C is the boiling point of water. In Fahrenheit, the freezing point of water is 32°F and the boiling point is 212°F.

The Celsius and Fahrenheit scales are equal at the point -40°C = -40°F, often referred to as the absolute zero point. The difference between the two scales is that for every degree Celsius, there are 1.8 degrees Fahrenheit. This means that to convert from Celsius to Fahrenheit, one must multiply the Celsius temperature by 1.8 and then add 32.

For example, if the Celsius temperature is 37°C, this would be equal to 98.6°F (37 x 1.8 + 32 = 98.6°F). This makes it easy to remember the formula; simply multiply the Celsius temperature by 1.8 and then add 32 to get the Fahrenheit temperature.

To express the quadratic function f(x) = x^2 - 18x + 63 in standard form, we need to complete the square.

First, we can factor out the coefficient of x^2, which is 1: f(x) = 1(x^2 - 18x + 63), Next, we want to find the value that completes the square for the expression inside the parentheses,

which is (-18x + 63). To do this, we take half of the coefficient of x, which is -9, square it, and add it to both sides: f(x) = 1(x^2 - 18x + 81 - 81 + 63).

Notice that we added and subtracted 81 inside the parentheses, which is the value we got from (-9)^2. This allows us to write the expression as a perfect square trinomial, which can be factored as: f(x) = 1[(x - 9)^2 - 18].

Finally, we can simplify this expression by distributing the 1 and adding 63 outside the brackets: f(x) = (x - 9)^2 - 18 + 63, So the quadratic function f(x) in standard form is: f(x) = (x - 9)^2 + 45.

Note that standard form for a quadratic function is usually written as ax^2 + bx + c, where a, b, and c are constants. In this case, we factored out the coefficient of x^2, which is why our standard form expression doesn't have an "a" term.

A quadratic function in standard form is written as f(x) = a(x - h)^2 + k, where a, h, and k are constants. Our goal is to rewrite the given function in this format. So, the standard form of the given quadratic function is: f(x) = (x - 9)^2 - 18

Answer:

Step-by-step explanation:

1 shower job requires 3 hours of work,

plumber will fix only 1 shower that means he will work for 3 hours,

Charges of 1 hour = 25$

Charges of 3 hour = 25× 3 = 75$

The currency that plumber accept is British pound (£),

1 British pound (£) = 1.62 dollar ($)

x British pound = 75 dollar

\( \frac{1}{x} = \frac{1.62}{75} \)

taking reciprocal both the side,

\( \frac{x \cancel £}{1\cancel£} = \frac{75 \: \cancel\$ }{1.62 \:\cancel \$} \)

\(x = 46.296\)

Jamar need to pay 46.296 British Pounds to plumber for the shower job.

Answer:

The answer is B.

Step-by-step explanation:

We can evaluate the integral on the right side to find the particular solution for the given initial condition y(0) = 5.

(i) To determine if the given differential equation is linear, we need to check if the dependent variable y and its derivatives appear linearly (raised to the power of 1) and without any products or compositions. In the given differential equation dy/dx = e^(-x^2) (2x+1)sin(x) - 2xy, we can see that y and its derivative dy/dx appear linearly. Therefore, the given differential equation is linear.

(ii) In a linear first-order differential equation in the form dy/dx + p(x)y = q(x), the coefficient of y is denoted as p(x), and the right-hand side of the equation is denoted as q(x). Comparing this with the given differential equation dy/dx = e^(-x^2) (2x+1)sin(x) - 2xy, we can identify p(x) as -2x and q(x) as e^(-x^2) (2x+1)sin(x).

(iii) To find the particular solution given the initial condition y(0) = 5, we can solve the differential equation. Rearranging the given equation, we have:

dy/dx + 2xy = e^(-x^2) (2x+1)sin(x)

This is a linear first-order ordinary differential equation. We can solve it using an integrating factor. The integrating factor is given by the exponential of the integral of p(x) dx:

I(x) = e^(∫2x dx) = e^(x^2)

Multiplying the entire differential equation by the integrating factor, we get:

e^(x^2) dy/dx + 2xye^(x^2) = e^(-x^2) (2x+1)sin(x) e^(x^2)

Simplifying the left side using the product rule, we have:

d/dx (e^(x^2) y) = e^(-x^2) (2x+1)sin(x) e^(x^2)

Integrating both sides with respect to x, we obtain:

e^(x^2) y = ∫(e^(-x^2) (2x+1)sin(x) e^(x^2)) dx

The integral on the right side can be simplified as it cancels out the exponential terms:

e^(x^2) y = ∫(2x+1)sin(x) dx

Integrating the right side using integration techniques, we can find the antiderivative. Once we have the antiderivative, we divide both sides by e^(x^2) to isolate y:

y = (1/e^(x^2)) ∫(2x+1)sin(x) dx

Using numerical or numerical approximation methods, we can evaluate the integral on the right side to find the particular solution for the given initial condition y(0) = 5.

We can generate 2 repeats or groups of 3/8 by adding the sums.

What is summation?

A summation, which is the result of adding two or more numbers or quantities, is also known as a sum. A summation always has an integer number of terms.

If we add 3/8 and 3/8

⇒ 3/8 + 3/8 = 6/8

If we again add 3/8

⇒ 6/8 + 3/8 = 9/8 > 1

It means we can only 2 times allowed to add 3/8 to get 1.

3/8 + 3/8 + x = 1

6/8 + x = 1

x = 1 - 6/8

x = 2/8

3/8 + 3/8 + 2/8 = 1
