The plot makes it obvious that the residuals are not indiscriminate; rather, they are forming a U-shape. Thus, we might infer that fitting a nonlinear model is preferable to doing so for a linear one.

Residual plot

The residual value of a regression line measures how much vertically a data point is missing. Regression lines offer the greatest fit for a collection of data. You can think of the lines as averages; some data points will fit the line while others won't. The independent variable is plotted on the horizontal axis, while the residual values are plotted on the vertical axis.

A residual plot is frequently used to identify regression problems. For some sets of data, regression is not a good fit, such as:

Data sets include outliers.

A residual plot makes these flaws more obvious than when viewing a representation of the original data set. Ideal residual values distribution on the horizontal axis should be uniform and random.

Answer: -3 + 3x/2 i believe this is the answer

Step-by-step explanation:

Answer: If the question is asking to make it into slope-intercept form then the answer is y= -3x/2 + 3

Step-by-step explanation:

To solve the given system of equations, let's go through the steps:

Step 1: Rearrange the equations:

2 = 4x₁ + 4x₂

0 = ₁x₁ + €₂x₂

0 = ₁₂x² + ₂x²

0 = C₁x² + ₂x

Step 2: Rewrite the system of equations in matrix form:

⎡ 4 4 ⎤ ⎡ x₁ ⎤ ⎡ 2 ⎤

⎢ ₁ €₂⎥ ⎢ x₂ ⎥ = ⎢ 0 ⎥

⎣ ₁₂ ₂⎦ ⎣ x² ⎦ ⎣ 0 ⎦

⎡ 4 4 ⎤ ⎡ x₁ ⎤ ⎡ 2 ⎤

⎢ ₁ €₂⎥ ⎢ x₂ ⎥ = ⎢ 0 ⎥

⎣ C₁ ₂ ⎦ ⎣ x ⎦ ⎣ 0 ⎦

Step 3: Calculate the determinant of the coefficient matrix:

det ⎡ 4 4 ⎤ = 4(€₂) - 4(₁) = 4€₂ - 4₁

⎢ ₁ €₂⎥

Step 4: Set the determinant equal to zero and solve for €₂:

4€₂ - 4₁ = 0

4€₂ = 4₁

€₂ = ₁

Step 5: Substitute the value of €₂ back into the original equations:

4x₁ + 4x₂ = 2

x₁ + ₁x₂ = 0

C₁x² + ₂x = 0

Step 6: Solve the system of equations using any method of your choice. The specific solution will depend on the values of €₁ and C₁.

Answer:

5x - y = - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x - 12 ← is in slope- intercept form

with slope m = 5

• Parallel lines have equal slopes , then

y = 5x + c ← is the partial equation

to find c substitute (- 2, - 6 ) into the partial equation

- 6 = - 10 + c ⇒ c = - 6 + 10 = 4

y = 5x + 4 ← in slope- intercept form ( subtract 5x from both sides )

- 5x + y = 4 ( multiply through by - 1 )

5x - y = - 4 ← in standard form

The probability that the proportion of overweight or obese children in the sample will be greater than 0.57 is less than 50%.

The first paragraph summarizes the answer, stating that the probability is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

In the second paragraph, we can explain the reasoning behind this conclusion. The Central Limit Theorem states that for a large sample size, the sampling distribution of the sample proportion will be approximately normal, regardless of the shape of the population distribution. In this case, the sample was taken in a way that meets the conditions for using the Central Limit Theorem.

Since the population proportion of overweight or obese children is 0.60, any sample proportion below this value is more likely to occur. Therefore, the probability of obtaining a sample proportion greater than 0.57 would be less than 50%. This is because the resulting z-score, which measures how many standard deviations the sample proportion is away from the population proportion, would be negative.

To summarize, the probability of the proportion of overweight or obese children in the sample being greater than 0.57 is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

To ensure a zero cash flow in the portfolio, the writer needs to set up a portfolio that offsets the cash flow from selling the derivatives. The writer should have -3 underlying assets in the portfolio (meaning short sold assets)

The cash flow from selling 100 derivatives can be calculated as:

Cash Flow from selling derivatives = 100 * (Premium at time 0 - Expiry value)

Cash Flow from selling derivatives = 100 * (1.34 - 0.64) = 70

To offset this cash flow, the writer needs to include an equal and opposite cash flow from the underlying assets. Let's assume the writer buys ""x"" underlying assets.

Cash Flow from underlying assets = x * (Value at time 0 - Value at time 1)

Cash Flow from underlying assets = x * (36 - 57) = -21x

To make the cash flow from underlying assets equal to the cash flow from selling derivatives, we set up the equation:

-21x = 70

Solving this equation, we find:

x ≈ -3.33

Since the number of underlying assets must be an integer, we round -3.33 to the nearest integer, which is -3.

Therefore, the writer should have -3 underlying assets in the portfolio (meaning short sold assets).

Answer:

The answer is A. Yes, because the points in the plot are all very close to the line, which indicates a strong association.

Step-by-step explanation:

plouto answer

Answer:

Yes, because the points in the plot are all very close to the line, which indicates a strong association.

Step-by-step explanation:

When the points in a scatter plot are very close to the line of best fit, there is a strong association between the two variables and the line of best fit can be expected to make reliable predictions.

So, yes, the line of best fit could be used to make reasonable predictions, because the points in the plot are all very close to the line, which indicates a strong association.

The height of the right triangle is 24 centimeters. This is determined by solving the equation for the area of the triangle, which is given as 96 cm², and considering that the height is 3 times the length of the base. By substituting the values and solving the equation, we find that the height is indeed 24 centimeters.

To determine the height of the right triangle, we can use the formula for the area of a triangle, which is given by the formula A = (1/2) * base * height. In this case, the area is known to be \(96 cm^2\).

Let's denote the length of the base as x. According to the problem statement, the height is 3 times the length of the base, so the height can be expressed as 3x.

Substituting these values into the area formula, we get:

\(96 = (1/2) * x * 3x\)

Simplifying the equation:

\(96 = (3/2) * x^2\)

To solve for x, we can divide both sides of the equation by (3/2):

\(64 = x^2\)

Taking the square root of both sides, we find:

x = 8

Since the height is 3 times the length of the base, the height is:

3 * 8 = 24 centimeters.

Therefore, the height of the right triangle is 24 centimeters.

The best point estimate for the mean monthly car payment for all residents of the local apartment complex is 631

The best point estimate for the mean monthly car payment for all residents of the local apartment complex is simply the sample mean, which is $631. This is because the sample mean is an unbiased estimator of the population mean, meaning that on average, it will give us an accurate estimate of the true population mean.

To explain this in mathematical terms, let's use X to represent the monthly car payment for an individual resident of the apartment complex. We have a sample of n=97 residents, and we can calculate the sample mean as follows:

\($\bar{X} = \frac{1}{n} \sum_{i=1}^{n} X_i$\)

In this case, we know that \(\bar{X} = $631,\) so this is our point estimate for the population mean:

\($\mu \approx \bar{X} = 631$\)

Answer:

Since it is negative they lost yards.

Step-by-step explanation:

the solution to the equation 9w = 5w + 20 is w = 5.

To solve the equation 9w = 5w + 20, we can start by simplifying both sides of the equation. By subtracting 5w from both sides, we obtain:

9w - 5w = 5w - 5w + 20

Simplifying further, we have:

4w = 20

To isolate the variable w, we divide both sides of the equation by 4:

4w/4 = 20/4

This simplifies to:

w = 5

Therefore, the solution to the equation 9w = 5w + 20 is w = 5.

Step-by-step explanation:

The probability of getting:

a) 2 apples is 5/33

b) 1 apple and 1 orange 35/132 .

Here, we have,

given that,

A fruit basket contains 5 apples and 7 oranges.

Paul picks a fruit at random from the basket and eats it.

He then picks another fruit at random to eat.

so, we get,

total number of fruits = 12

now, we have,

a) P( pick 1 apple) = 5/12

then, P( pick another 1 apple) = 4/11

so, we get,

P( picking 2 apples) = 5/12 * 4/11 = 20/132 = 5/33

b) P( pick 1 apple) = 5/12

then, P( pick 1 orange) = 7/11

so, we get,

P( picking 1 apple and 1 orange) = 5/12 *  7/11 = 35/132

Hence, The probability of getting:

a) 2 apples is 5/33

b) 1 apple and 1 orange 35/132 .
