A gaming store marks up the video games it receives from the manufacturer 30%. Which expressions can be used to determine the price the store charges when the manufacturer charges x dollars? Select all that apply.

Answer:

(x+10)² + (y+5)² = 125

Step-by-step explanation:

We are given that a circle has a center (-10,-5), and passes through the point (-5,5).

We want to write the equation of this circle in the standard equation. The standard equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.

As we are already given the center point, we can substitute its values into the equation.

Reminder: the equation uses negative values, and we have negative numbers.

(x--10)² + (y--5)² = r²

This can be simplified to:

(x+10)² + (y+5)² = r²

Now, we need to find r².

As the point passes through (-5,5), we can use its values to solve for r².

Substitute -5 as x and 5 as y.

(-5+10)² + (5+5)² = r²

(5)² + (10)² = r²

25 + 100 = r²

125=r²

The radius is 125

Substitute 125 as r².

(x+10)² + (y+5)² = 125

If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.

So, the answer is:

a. MSwithin > MSbetween

If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

Answer:

∠A = 100

∠B = 50

∠C = 30

Step-by-step explanation:

Sum of all angles of triangle = 180

∠A + ∠B + ∠C = 180

2x +x + x - 20 = 180  {Combine like terms}

4x - 20 = 180      

Add 20 to both sides

4x = 180 + 20

4x = 200

Divide  both sides by 4

x = 200/4

x = 50

∠A = 2x = 2*50 = 100

∠B = x = 50

∠C = x - 20 = 50 - 20 = 30

Answer:

A. The probability that one selected subcomponent is longer than 122 cm can be found by calculating the area under the normal distribution curve to the right of 122 cm. We can use the z-score formula to standardize the value and then look up the corresponding probability in the standard normal distribution table.

z = (122 - μ) / σ = (122 - 100) / 5.6 = 3.93 (approx.)

Looking up the corresponding probability for a z-score of 3.93 in the standard normal distribution table, we find that it is approximately 0.9999. Therefore, the probability that one selected subcomponent is longer than 122 cm is approximately 0.9999 or 99.99%.

B. To find the probability that the mean length of three randomly selected subcomponents exceeds 122 cm, we need to consider the distribution of the sample mean. Since the sample size is 3 and the subcomponent lengths are normally distributed, the distribution of the sample mean will also be normal.

The mean of the sample mean will still be the same as the population mean, which is 100 cm. However, the standard deviation of the sample mean (also known as the standard error) will be the population standard deviation divided by the square root of the sample size.

Standard error = σ / √n = 5.6 / √3 ≈ 3.24 cm

Now we can calculate the z-score for a mean length of 122 cm:

z = (122 - μ) / standard error = (122 - 100) / 3.24 ≈ 6.79 (approx.)

Again, looking up the corresponding probability for a z-score of 6.79 in the standard normal distribution table, we find that it is extremely close to 1. Therefore, the probability that the mean length of three randomly selected subcomponents exceeds 122 cm is very close to 1 or 100%.

C. If we want to find the probability that all three randomly selected subcomponents have lengths exceeding 122 cm, we can use the probability from Part A and raise it to the power of the sample size since we need all three subcomponents to satisfy the condition.

Probability = (0.9999)^3 ≈ 0.9997

Therefore, the probability that if three subcomponents are randomly selected, all three of them have lengths that exceed 122 cm is approximately 0.9997 or 99.97%.

Based on the given information about the normal distribution of subcomponent lengths, we calculated the probabilities for different scenarios. We found that the probability of selecting a subcomponent longer than 122 cm is very high at 99.99%. Similarly, the probability of the mean length of three subcomponents exceeding 122 cm is also very high at 100%. Finally, the probability that all three randomly selected subcomponents have lengths exceeding 122 cm is approximately 99.97%. These probabilities provide insights into the performance of the automatic machine in terms of producing longer subcomponents.

After the Civil War, many farmers struggled and felt victimized by banks and big business. Self-help clubs for farmers, called granges, sprang up all over the Midwest. Pressure from grangers led some states to pass laws limiting railroad shipping rates and prices for grain storage. Big businesses protested this interference and sometimes sued. In a series of cases, the Supreme Court sided with the granges, strengthening the idea that the government has a responsibility to protect the common good. As conditions improved, membership in the granges dropped. By the mid-1870s, the National Grange had grown into a political force.

Answer:

-1/24 < x < 0

Step-by-step explanation:

Answer: 25

Step-by-step explanation:

the exterior angle at q is 155, and the exterior and interior angle add up to 180. so, the interior angle at q is 180-155, which equals 25. angle PSR is across from interior angle q, and in parallelograms, angles across from one another must equal each other. this means that for PQRS to be a parallelogram, angle PSR must be 25 degrees.

Hannah's debt-to-equity ratio when her liabilities was $30,000 (excluding her mortgage of $100,000 ) and her net worth is $45,000 is 0.75.

Debt-to-equity ratio is a financial ratio that measures the proportion of total liabilities to shareholders' equity. To calculate the debt-to-equity ratio for Hannah, we need to first calculate her total liabilities and shareholders' equity.

We are given that Hannah has liabilities of $30,000 excluding her mortgage of $100,000. Therefore, her total liabilities are $30,000 + $100,000 = $130,000.

We are also given that her net worth is $45,000. The net worth is calculated by subtracting the total liabilities from the total assets. Therefore, the shareholders' equity is $45,000 + $130,000 = $175,000.

Now we can calculate the debt-to-equity ratio by dividing the total liabilities by the shareholders' equity.

Debt-to-equity ratio = Total liabilities / Shareholders' equity = $130,000 / $175,000 = 0.74 (rounded to two decimal places)

Therefore, Hannah's debt-to-equity ratio is 0.74, which is closest to option 0.75.

The survey method that is most likely to lead to nonresponse bias in the sample when gathering opinions regarding a tuition increase for online degree programs is an online survey.

Conducting an online survey is the survey method that is most likely to lead to nonresponse bias in this scenario. Nonresponse bias occurs when certain groups within the population are less likely to respond to the survey, resulting in a sample that does not accurately represent the entire population.

In the case of an online survey, there are several factors that can contribute to nonresponse bias. First, not all students may have reliable internet access or may not regularly check their emails or online accounts, leading to a lower response rate among these individuals. This can result in an overrepresentation of students who have easy access to online resources and are more likely to participate in the survey.

Additionally, students who feel strongly about the tuition increase may be more motivated to complete the survey, while those who are indifferent or opposed to the increase may be less inclined to respond. This can lead to a biased sample that overrepresents the opinions of students who are in favor of the tuition increase, potentially skewing the results.

Therefore, it is important to consider alternative survey methods, such as in-person interviews or paper surveys, to mitigate nonresponse bias and ensure a more representative sample of student opinions regarding the tuition increase for online degree programs.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

First we find the square root of 100(for this we use a calculator)

\(\sqrt{100\\}\) = 10

The square root of 100 is 10.

Now locate 10 on a number line.

The linearization of the function f(x, y) = 3xy^2 + 2y at the point (1, 3) is L(x, y) = 17 + 15(x - 1) + 18(y - 3). Using this linear approximation, we can approximate value of f(1.2, 3.5) as L(1.2, 3.5) = 17 + 15(0.2) + 18(0.5) = 21.7.

To find the linearization of f(x, y) = 3xy^2 + 2y at (1, 3), we first calculate the partial derivatives of f with respect to x and y:

∂f/∂x = 3y^2

∂f/∂y = 6xy + 2

Next, we evaluate these partial derivatives at (1, 3):

∂f/∂x (1, 3) = 3(3)^2 = 27

∂f/∂y (1, 3) = 6(1)(3) + 2 = 20

Using the point-slope form of a linear equation, we construct the linearization:

L(x, y) = f(1, 3) + ∂f/∂x (1, 3)(x - 1) + ∂f/∂y (1, 3)(y - 3)

       = 17 + 27(x - 1) + 20(y - 3)

       = 17 + 27x - 27 + 20y - 60

       = 15x + 20y - 70

       = 17 + 15(x - 1) + 18(y - 3)

Now, to approximate the value of f(1.2, 3.5), we substitute the given values into the linear approximation:

L(1.2, 3.5) = 17 + 15(0.2) + 18(0.5)

           = 21.7

Therefore, using the linearization, we can approximate the value of f(1.2, 3.5) as approximately 21.7.
