what is the quadrant of 51, -1

Answer:

26.6666667

Step-by-step explanation:

The selection depends on individual needs, preferences, and the intended use of the tiny house.

a) To find the amount of space inside each house, we need to calculate the volume for each design.

House on the left:

Volume = length x width x height = 2.5 m x 18 m x 2.8 m = 126 m³

Triangular house:

Volume of a triangular prism = (base area x height) / 2

Base area = (1/2) x base x height = (1/2) x 4 m x 10 m = 20 m²

Volume = (20 m² x 7 m) / 2 = 70 m³

b) When comparing the environmental impacts of each house, several factors need to be considered:

Positive impacts:

1. Material usage: Tiny houses use fewer materials, reducing resource consumption and waste generation.

2. Energy efficiency: Smaller living spaces require less energy for heating, cooling, and lighting, leading to lower energy consumption.

3. Land utilization: Tiny houses can be built on smaller plots of land, preserving green spaces and reducing urban sprawl.

Negative impacts:

1. Construction materials: Although tiny houses use less material overall, the environmental impact depends on the types of materials used. Sustainable and eco-friendly materials should be prioritized.

2. Water and waste management: Adequate provisions for water supply and waste disposal should be implemented to minimize environmental impacts.

3. Transportation: The transportation of tiny houses to their locations can contribute to carbon emissions if not done efficiently.

c) The choice of design for a tiny house depends on personal preferences and priorities. However, considering the provided information:

The house on the left offers a larger interior space of 126 m³, providing more room for living and storage. It may be suitable for individuals or couples who desire more space and functionality within their tiny house.

The triangular house has a smaller interior volume of 70 m³ but offers a unique design and aesthetic appeal. It may be preferred by individuals who prioritize a distinctive architectural style or who are looking for a minimalist and cozy living space.

Ultimately, the selection depends on individual needs, preferences, and the intended use of the tiny house. Factors such as lifestyle, desired amenities, and personal values regarding sustainability and resource conservation should be considered when making the final decision.

The disparities between the actual and anticipated values in a regression model were referred to as residuals in the context Tufte provided.

American statistician Edward Rolf Tufte is a retired professor of political science, statistics, and computer science at Yale University.

Tufte talked about the idea of residuals. The discrepancies between the actual value and the projected value are known as residuals in statistics. Depending on whether the observed value is higher or lower than the projected value, they might be either positive or negative.

A model's residuals offer a gauge of how well it matches the data. According to him, residual plots are a great tool for seeing issues with the model fit and spotting outliers that might be skewing the results.

In contrast to relying exclusively on statistical tests, Tufte emphasised the significance of visually evaluating residuals since graphs can highlight patterns and correlations that may be missed in the numbers.

Overall, residuals are a key idea in statistics since they may be used to evaluate a model's reliability and point out its flaws.

In a t-test, if the resultant t value is -2.72 and p < 0.05, the interpretation is that there is a significant difference between the sample value and the population. The correct option is B.

A t-test is a statistical test that determines whether there is a significant difference between the means of two groups. In general, a t-test is used to determine if two sets of data are significantly different from each other.

For example, suppose a researcher wants to know whether a new drug reduces the number of headaches experienced by patients. The researcher would conduct a t-test to determine whether the difference in the number of headaches experienced by patients who receive the drug is significantly different from those who do not receive the drug.

The p-value is the probability of obtaining a result as extreme or more extreme than the observed result if the null hypothesis is true.

If the p-value is less than the significance level, then the null hypothesis is rejected, and it is concluded that the alternative hypothesis is true.

In the given question, the t-value is -2.72 and p < 0.05, which means the p-value is less than the significance level (0.05), which means the null hypothesis is rejected, and the alternative hypothesis is accepted.

Therefore, there is a significant difference between the sample value and the population, and the correct answer is option B.

Compare two similar sides:

24:32 this reduces to 3:4

Answer: D) 3:4

Answer:

Step-by-step explanation:

You want the values of x and y when corresponding angles at parallel lines are marked (9x -14)° and (7x +18)°, and a vertical angle to those is marked y°.

Corresponding angles where a transversal crosses parallel lines are congruent:

  (9x -14)° = (7x +18)°

  2x = 32 . . . . . . . . . . divide by °, add 14-7x

  x = 16

Then these angles are ...

  (9(16) -14)° = (144 -14)° = 130°

Vertical angles are congruent, so ...

  y° = 130°

  y = 130

The probability P(GH) is 0%.

Since we know that,

Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one.

Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur.

This is the fundamental probability theory, which is also utilized in probability distribution, in which you will learn about the possible results of a random experiment.

To determine the likelihood of a particular event occurring, we must first determine the total number of alternative possibilities.

Now to find the probability of GH,

We can see that there is no any poit G and H are showing in the given number line,

Therefore,

Favorable outcomes = 0

Since we know that,

Probability = number of favorable outcomes/total number of outcomes

Thus,

⇒ P(GH) = 0/total number of outcomes

Hence,

⇒ P(GH) = 0%

The parametric equations for the line of intersection of the planes 4x - 3y + z = 1 and 3x + y - 4z = 4 are:

x = (208 + 70t) / 52

y = (13 + 19t) / 13

z = t

To find the parametric equations for the line of intersection of the planes 4x - 3y + z = 1 and 3x + y - 4z = 4, we can solve these two equations simultaneously.

Step 1: Set up a system of equations:

4x - 3y + z = 1

3x + y - 4z = 4

Step 2: Solve the system of equations to find the values of x, y, and z. One way to solve the system is by using the method of elimination:

Multiply the first equation by 3 and the second equation by 4 to eliminate the y term:

12x - 9y + 3z = 3

12x + 4y - 16z = 16

Subtract the first equation from the second equation:

12x + 4y - 16z - (12x - 9y + 3z) = 16 - 3

12x + 4y - 16z - 12x + 9y - 3z = 13y - 19z = 13

Step 3: Express y and z in terms of a parameter, let's call it t:

13y - 19z = 13

y = (13 + 19z) / 13

We can take z as the parameter t:

z = t

Substituting the value of z in terms of t into the equation for y:

y = (13 + 19t) / 13

Step 4: Express x in terms of t:

From the first equation of the original system:

4x - 3y + z = 1

4x - 3((13 + 19t) / 13) + t = 1

4x - (39 + 57t) / 13 + t = 1

4x - (39 + 57t + 13t) / 13 = 1

4x - (39 + 70t) / 13 = 1

4x = (39 + 70t) / 13 + 1

x = ((39 + 70t) / 13 + 13) / 4

x = (39 + 70t + 169) / 52

x = (208 + 70t) / 52

Therefore, the parametric equations for the line of intersection of the planes 4x - 3y + z = 1 and 3x + y - 4z = 4 are:

x = (208 + 70t) / 52

y = (13 + 19t) / 13

(a) The function y over x can be represented as y = x × 59 - 80,000. (b) Hang needs to save approximately 2,034.48 dong every day to have enough money to buy the shoes.

To calculate the function y over x, we need to consider the amount of money Hang has after saving for the shoes.
a) Hang plans to save money from February 1, 2020, to March 31, 2020, which is a total of 59 days. Let's assume Hang saves x (dong) per day. So the total amount of money saved is x × 59.
After buying the shoes for 680,000 dong, Hang has 600,000 dong left.

Therefore, the function y over x can be represented as:
y = x  × 59 - 680,000 + 600,000
Simplifying the equation, we get:
y = x × 59 - 80,000
b) Hang's grandparents give lucky money of 360,000 dong to both sisters, which is divided according to the age ratio. As Hang is 15 years old and her younger brother is 12, the age ratio is 15:12 or 5:4.
To find out how much money Hang needs to save every day, we need to divide the remaining amount of money (y) by the number of days (59). So the equation becomes:
(x × 59 - 80,000) / 59 = (360,000 / (5 + 4))
Simplifying the equation, we get:
x × 59 - 80,000 = 40,000
Rearranging the equation, we find:
x × 59 = 120,000
Dividing both sides by 59, we get:
x = 2,034.48 dong

Using central limit theorem, the shape of the sample proportions is normal

The shape of the sample distribution can be found using central limit theorem (CLT) which states that that "if you take sufficiently large samples from a population, the samples’ means will be normally distributed, even if the population isn’t normally distributed."

In this problem, our sample size is 10 and the population proportion is 52% which is roughly 0.5 and still reasonable, we can use CLT to approximate the shape of the sample proportion.

mean = 0.52

standard error = √(p(1 - p(hat) / n) = √(0.53 * 0.48) / 10 = 0.15

Step-by-step explanation:

The acceleration of an object increases with increased forced and decreases with increased mass which is in the same direction as the force.

To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.

1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.

2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.

3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.

4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.

5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].

6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.

7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

So it’ll be

2x-3y=-14

2x=-14+3y

x=-7+1.5y

X is -7+1.5y

Now you can subsitute into other equations to find what Y is worth

So lets use the second equation

5(-1+1.5y) + 9y = 14

Now solve for y which is -2

If you subsitute Y back in an equation you’d get -4 for x

So y = -2
