Let X_1,…,X_n be a random sample. For S(X_1,…,X_n )=1/(1/n ∑_(i=1)^n▒〖(x_i-c)〗^2 ) , find its asymptotic distribution where EX^k=α_k.

Answers

The asymptotic distribution of the estimator S(X₁, ..., Xₙ) is a standard normal distribution, denoted as N(0, 1).

To find the asymptotic distribution of the estimator S(X₁, ..., Xₙ), we can use the Central Limit Theorem (CLT). However, we need some additional assumptions to apply the CLT, such as the finite variance of the random variables.

Given that E(Xᵢ^k) = αₖ for all k, we can assume that the random variables Xᵢ have a finite variance. Let's denote the variance of Xᵢ as Var(Xᵢ) = σ².

First, let's simplify the estimator S(X₁, ..., Xₙ):

S(X₁, ..., Xₙ) = 1 / (1/n ∑ᵢ (Xᵢ - c)²)

Notice that the numerator is a constant and doesn't affect the asymptotic distribution. So, we can focus on analyzing the denominator.

Let's calculate the expected value and variance of the denominator:

E[1/n ∑ᵢ (Xᵢ - c)²] = 1/n ∑ᵢ E[(Xᵢ - c)²] = 1/n ∑ᵢ (Var(Xᵢ) + E[Xᵢ]² - 2cE[Xᵢ] + c²)

= 1/n (nσ² + α₁ - 2cα₁ + c²) (using the fact that E[Xᵢ] = α₁ for all i)

Var[1/n ∑ᵢ (Xᵢ - c)²] = 1/n² ∑ᵢ Var[(Xᵢ - c)²] = 1/n² ∑ᵢ (Var(Xᵢ - c)²) = 1/n² ∑ᵢ (Var(Xᵢ))

= 1/n² (nσ²) = σ²/n

Now, let's apply the CLT. According to the CLT, if we have a sequence of independent and identically distributed random variables with a finite mean (μ) and a finite variance (σ²), the sample mean (in this case, our denominator) converges in distribution to a standard normal distribution as the sample size approaches infinity.

Therefore, as n approaches infinity, the asymptotic distribution of S(X₁, ..., Xₙ) will follow a standard normal distribution.

Christina is buying a $170,000 home with a 30-year mortgage. She makes a $20,000 down payment.
Use the table to find her monthly PMI payment.
A. $51.25
B. $37.50
C. $23.75
D. $42.50

Answers

The monthly PMI Payment for Christina's loan is $37.50.The correct answer is option B.

To determine Christina's monthly PMI (Private Mortgage Insurance) payment, we need to find the corresponding interest rate for her loan-to-value (LTV) ratio. The LTV ratio is calculated by dividing the loan amount by the property value.

The loan amount can be calculated by subtracting the down payment from the property value:

Loan amount = Property value - Down payment

           = $170,000 - $20,000

           = $150,000

Now we can calculate the LTV ratio:

LTV ratio = Loan amount / Property value * 100

         = $150,000 / $170,000 * 100

         = 88.24%

Since Christina is obtaining a 30-year mortgage, we need to look at the interest rates for LTV ratios between 85.01% and 90%. According to the table, the interest rate for this range is 0.30%.

To calculate the PMI payment, we multiply the loan amount by the PMI rate and divide it by 12 months:

PMI payment = (Loan amount * PMI rate) / 12

           = ($150,000 * 0.30%) / 12

           = $450 / 12

           = $37.50

A sample of gas stored at ST has a volume of 3.56 L. The gas is heated to 400 K and has a pressure of 125 kPa. What is the volume of the gas after it is heated?

Answers

The volume of the gas after it is heated is approximately 0.0417 liters.

To find the volume of the gas after it is heated, we can use the combined gas law, which relates the initial and final conditions of a gas sample. The combined gas law is expressed as:

(P₁V₁) / T₁ = (P₂V₂) / T₂

Where:

P₁ and P₂ are the initial and final pressures of the gas (in kPa)

V₁ and V₂ are the initial and final volumes of the gas (in liters)

T₁ and T₂ are the initial and final temperatures of the gas (in Kelvin)

Given:

Initial volume (V₁) = 3.56 L

Initial temperature (T₁) = ST (which is typically 273.15 K)

Final temperature (T₂) = 400 K

Final pressure (P₂) = 125 kPa

Now we can plug these values into the combined gas law equation and solve for V₂:

(P₁V₁) / T₁ = (P₂V₂) / T₂

(1 * 3.56) / 273.15 = (125 * V₂) / 400

(3.56 / 273.15) = (125 * V₂) / 400

Cross-multiplying and solving for V₂:

3.56 * 400 = 273.15 * 125 * V₂

1424 = 34143.75 * V₂

V₂ = 1424 / 34143.75

V₂ ≈ 0.0417 L

As a result, the heated gas has a volume of approximately 0.0417 litres.

21. Determine whether CD || AB. Explain your reasoning.​

Answers

Answer: CD is not parallel to AB.

Reason:

If CD was parallel to AB, then triangles CDE and ABE would be similar. In turn it would mean that EA/EC = EB/ED is a true proportion.

Let's calculate each side separately.

EA/EC = 28/(28+20) = 0.5833EB/ED = 16/(16+10) = 0.6154

Both decimal values are approximate.

The two values don't match up which makes EA/EC = EB/ED to be false.

Since EA/EC = EB/ED is false, we know that triangles CDE and ABE are not similar. Therefore, CD is not parallel to AB.

Answer:

CD is not parallel to AB

Step-by-step explanation:

According to the Side Splitter Theorem, if a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.

Therefore, if CD is parallel to AB, then EA : AC = EB : BD.

Substitute the values of the line segments into the equation:

[tex]\begin{aligned}EA : AC &= EB : BD\\\\28:20&=16:10\\\\\dfrac{28}{20}&=\dfrac{16}{10}\\\\1.4 &\neq 1.6\end{aligned}[/tex]

As 1.4 does not equal 1.6, then CD is not parallel to AB.

The function that satisfies the given condition is y = 3x + 2.

The correct answer to the given question is option B.

We are to find the function that satisfies the condition: When x increases from a to a + 2, y increases by a difference of 6.

A statement such as this represents a linear function, where y increases at a constant rate with respect to the increase in x.Let y = mx + b, be a linear function.

We know that when x increases from a to a + 2, y increases by a difference of 6. In other words, we can express this relationship using the following equation:

2m + b − m − b = 6 ⇒ m = 3

The function has been found to be y = 3x + b.

To find the value of b, we need to use the fact that when x increases from a to a + 2, y increases by a difference of 6: y(a + 2) − y(a) = 6 ⇒ 3(a + 2) + b − 3a − b = 6 ⇒ 6 = 6

What is the angle of intersecting chords theorem?

The angle of intersecting chords theorem states that the angle formed by the intersection of two chords in a circle is half the sum of the measure of the intercepted arcs.

The diameter of the circle AB indicates that we get;

PB is the perpendicular of the chord CD

CE = DE = 16

CD = CE + DE = 16 + 16 = 32

The chords CB and BD are congruent, therefore, according to the chords arc theorem, the arcs the chords intercepts are congruent.

Therefore; (4·x + 7)° = (5·x - 5)°

4·x + 7 = 5·x - 5

5·x - 4·x = 7 + 5 = 12

x = 12

[tex]m\widehat{BD}[/tex] = (5·x - 5)° = (5 × 12 - 5)° = 55°

[tex]m\widehat{BC}[/tex] = [tex]m\widehat{BD}[/tex] = 55°

[tex]m\widehat{CD}[/tex] = [tex]m\widehat{BC}[/tex] + [tex]m\widehat{BD}[/tex] = 55° + 55° = 110°

The angle of intersecting chords theorem indicates that we get;

90° = (1/2) × ((5·x - 5)° + m[tex]\widehat{AC}[/tex])

90° = (1/2) × ((4·x + 7)° + m[tex]\widehat{AD}[/tex])

Therefore; 2 × 90° = (4·x + 7)° + m[tex]\widehat{AD}[/tex]

(4·x + 7)° = 55°

Therefore; 2 × 90° = (4·x + 7)° + m[tex]\widehat{AD}[/tex] = 55° + m[tex]\widehat{AD}[/tex]

180° = 55° + m[tex]\widehat{AD}[/tex]

($ 00)?

Answers

Based on the data and the one-sample t-test, at the 0.05 level of significance, there is sufficient evidence to conclude that the average bear sales per store at Wal-Mart is significantly higher than $500

.

To determine if there is evidence that the average bear sales per store at Wal-Mart is more than $500 at the 0.05 level of significance, we can conduct a one-sample t-test. Let's go through the steps:

State the null and alternative hypotheses:

Null hypothesis (H₀): The average bear sales per store is equal to or less than $500.

Alternative hypothesis (H₁): The average bear sales per store is greater than $500.

Set the significance level (α):

In this case, the significance level is given as 0.05 or 5%.

Collect and analyze the data:

The weekly sales of bears in 10 stores are as follows:

8, 11, 0, 4, 7, 8, 10, 583

Calculate the test statistic:

To calculate the test statistic, we need to compute the sample mean, sample standard deviation, and the standard error of the mean.

Sample mean ([tex]\bar X[/tex]):

[tex]\bar X[/tex] = (8 + 11 + 0 + 4 + 7 + 8 + 10 + 583) / 8

[tex]\bar X[/tex] ≈ 76.375

Sample standard deviation (s):

s = √[Σ(x - [tex]\bar X[/tex])² / (n - 1)]

s ≈ 190.687

Standard error of the mean (SE):

SE = s / √n

SE ≈ 60.174

Now, we can calculate the t-value:

t = ([tex]\bar X[/tex] - μ₀) / SE

Where μ₀ is the hypothesized population mean ($500).

t = (76.375 - 500) / 60.174

t ≈ -7.758

Determine the critical value:

Since we are conducting a one-tailed test and the alternative hypothesis is that the average bear sales per store is greater than $500, we need to find the critical value for a one-tailed t-test with 8 degrees of freedom at a 0.05 level of significance. Looking up the critical value in the t-distribution table, we find it to be approximately 1.860.

Compare the test statistic with the critical value:

Since -7.758 is less than -1.860, we have enough evidence to reject the null hypothesis.

To find the mode, we can create a frequency table by counting the number of occurrences for each shoe size:

8     |     3

7     |     3

8.5 | 2

From the frequency table, we can see that both size 8 and size 7 appear three times each, while size 8.5 appears two times. Since both size 8 and size 7 have the highest frequency of occurrence (3), they are considered modal sizes. In this case, there is more than one mode, and we refer to it as a bimodal distribution.

To determine the mode, we performed a frequency count of each shoe size in the given data. We counted the number of occurrences for sizes 8, 7, and 8.5. Based on the frequency counts, we identified the sizes with the highest frequency, which turned out to be 8 and 7, both occurring three times. Thus, they are the modal sizes in the data set.

Which table of values represents a function? Step by step.

Answers

Answer:

A

Step-by-step explanation:

For a table of values to be a function, all inputs must have one unique output. The only table that doesn't violate this is table A.

Notice that while two different inputs (-4 and 1) have the same output of 7, it is still a function because both outputs of 7 are associated with two different inputs.

If two of the angles in a scalene triangle are 54° and 87°, what is the other angle?

Answers

Answer:

39°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

let the other angle be x , then

x + 54° + 87° = 180°

x + 141° = 180° ( subtract 141° from both sides )

x = 39°

that is the other angle is 39°

Final answer:

In a triangle, the sum of all angles is always 180°. To find the third angle in a scalene triangle where two angles are known, subtract the known angles from 180°. In this case, subtracting 54° and 87° from 180° gives a third angle of 39°.

Explanation:

The question refers to finding the third angle in a scalene triangle, where we know two of the angles. A scalene triangle is a triangle where all three sides are of a different length, and therefore all three angles are also different. The sum of the angles in any triangle is always 180°.

To find the third angle in the triangle, you can use the equation: Angle C = 180° - Angle A - Angle B.

So, we subtract the known angles from 180°: Angle C = 180° - 54° - 87° = 39°.

Therefore, the third angle in this scalene triangle is 39°.

A camera sensor with a fixed size of 720 × 680 is used in the system described in the article. For a sensor of these dimensions, calculate

i.the resolution in pixels in scientific notation to 4 significant figures

ii.the resolution in megapixels, rounded to the nearest thousandth of a megapixel

iii.the aspect ratio of the sensor, cancelled down to its lowest terms

Answers

i. To calculate the resolution in pixels, we multiply the width by the height of the sensor:
Resolution = 720 × 680 = 489,600 pixels.

In scientific notation to 4 significant figures, the resolution would be approximately 4.896 × 10^5 pixels.

ii. To find the resolution in megapixels, we divide the total number of pixels by 1 million:
Resolution in megapixels = 489,600 pixels / 1,000,000 = 0.4896 megapixels.

Rounded to the nearest thousandth of a megapixel, the resolution would be approximately 0.490 megapixels.

iii. The aspect ratio of the sensor can be found by dividing the width by the height and canceling down to its lowest terms:
Aspect ratio = 720 / 680 = 36 / 34.

Therefore, the aspect ratio of the sensor in its lowest terms is 18:17.
Final answer:

The pixel resolution is 4.896 x 10^5 pixels; in megapixels, it's approximately 0.490; and the aspect ratio is 18:17.

Explanation:

First, let's calculate the resolution in pixels: Resolution is simply the width times the height of the sensor. Specifically for this question, multiply 720 by 680. This gives us 489600 pixels for the resolution - in scientific notation to 4 significant figures we have 4.896 x 10^5.

Next, to calculate the resolution in megapixels, we need to divide the resolution by 1 million (since one megapixel is equal to 1 million pixels). So, 489600/1,000,000 is approximately 0.490 megapixels when rounded to the nearest thousandth of a megapixel.

Finally, the aspect ratio is the relationship of the width to the height of an image or screen. For a 720 x 680 sensor, if we divide 720 by 680, the result would be approximately 1.0588. However, we want this ratio in its simplest form, so we should use the greatest common divisor (GCD). In this case, the GCD of 720 and 680 is 40, so by dividing both dimensions by 40, we get an aspect ratio of 18:17.

Determine the surface area and volume Note: The base is a square.

Answers

The volume of the can is approximately 304 cubic centimeters.

To determine the surface area and volume of the can, we need to consider the properties of a cylinder with a square base.

Surface Area:

The surface area of the can consists of three parts: the square base and the two circular faces.

a) Square Base:

The base of the can is a square, so its area is given by the formula:

Area = side^2.

Since the diameter of the can is 8 centimeters, the side of the square base is also 8 centimeters.

Therefore, the area of the square base is 8 cm [tex]\times[/tex] 8 cm = 64 square centimeters.

b) Circular Faces:

The can has two circular faces, one at the top and one at the bottom.

The formula for the area of a circle is[tex]A = \pi \times r^2,[/tex] where r is the radius. The radius of the can is half the diameter, which is 8 cm / 2 = 4 cm.

Thus, the area of each circular face is [tex]\pi \times (4 cm)^2 = 16\pi[/tex]  square centimeters.

To find the total surface area, we sum the areas of the square base and the two circular faces:

Total Surface Area = Square Base Area + 2 [tex]\times[/tex] Circular Face Area

[tex]= 64 cm^2 + 2 \times 16\pi cm^2[/tex]

≈ [tex]64 cm^2 + 100.48 cm^2[/tex]

≈[tex]164.48 cm^2[/tex]

Therefore, the surface area of the can is approximately 164.48 square centimeters.

Volume:

The volume of the can is given by the formula:

Volume = base area [tex]\times[/tex] height.

Since the base is a square, the base area is equal to the side^2, which is 8 cm [tex]\times[/tex] 8 cm = 64 square centimeters.

The height of the can is the height we calculated earlier, which is approximately 4.75 centimeters.

Volume = Base Area [tex]\times[/tex] Height

[tex]= 64 cm^2 \times4.75[/tex] cm

≈ 304 [tex]cm^3[/tex]

Find the length of an isosceles 90 degree triangle with the hypothenuse of 4 legs x

Answers

The length of the hypotenuse in the isosceles 90-degree triangle is √(2).

In an isosceles 90-degree triangle, two legs are equal in length, and the third side, known as the hypotenuse, is longer. Let's denote the length of the legs as x and the length of the hypotenuse as 4x.

According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse. In this case, we have:

[tex]x^2 + x^2 = (4x)^2.[/tex]

Simplifying the equation:

[tex]2x^2 = 16x^2.[/tex]

Dividing both sides of the equation by [tex]2x^2[/tex]:

[tex]1 = 8x^2.[/tex]

Dividing both sides of the equation by 8:

[tex]1/8 = x^2[/tex].

Taking the square root of both sides of the equation:

x = √(1/8).

Simplifying the square root:

x = √(1)/√(8),

x = 1/(√(2) * 2),

x = 1/(2√(2)).

Therefore, the length of each leg in the isosceles 90-degree triangle is 1/(2√(2)), and the length of the hypotenuse is 4 times the length of each leg, which is:

4 * (1/(2√(2))),

2/√(2).

To simplify the expression further, we can rationalize the denominator:

(2/√(2)) * (√(2)/√(2)),

2√(2)/2,

√(2).

Answer:

The correct option is the 3rd one

angle 1 = angle 4 = angle 5 = angle 8 = 60 degrees,

angle 2 = angle 3 = angle 6 = angle 7 = 120 degrees

Step-by-step explanation:

To solve this, we only need to look at the top two angles, 1 and 2

Since line l is a line, angle 1 and 2 must sum to 180,

Since angle 1 = 60 degrees, then,

angle 1 + angle 2 = 180

60 + angle 2 = 180

angle 2 = 120 degrees

the only option that corresponds to this is the third option,

angle 1 = angle 4 = angle 5 = angle 8 = 60 degrees,

Anna volunteers on the weekend at the Central Library. As a school project, she decides to record how many people visit the library, and where they go. On Saturday, 382 people went to The Youth Wing, 461 people went to Social Issues, and 355 went to Fiction and Literature. On Sunday, the library had 800 total visitors. Based on what Anna had recorded on Saturday, about how many people should be expected to go to The Youth Wing? Round your answer to the nearest whole number.

Answers

Based on the data recorded by Anna on Saturday, we can estimate the number of people expected to visit The Youth Wing on Sunday.

Let's calculate the proportion of visitors to The Youth Wing compared to the total number of visitors on Saturday:

[tex]\displaystyle \text{Proportion} = \frac{\text{Visitors to The Youth Wing on Saturday}}{\text{Total visitors on Saturday}} = \frac{382}{382 + 461 + 355}[/tex]

Next, we'll apply this proportion to the total number of visitors on Sunday to estimate the number of people expected to go to The Youth Wing:

[tex]\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times \text{Total visitors on Sunday}[/tex]

Now, let's substitute the values into the equation and calculate the estimated number of visitors to The Youth Wing on Sunday:

[tex]\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355}[/tex]

[tex]\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times 800[/tex]

Calculating the proportion:

[tex]\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355} = \frac{382}{1198}[/tex]

Calculating the estimated number of visitors to The Youth Wing on Sunday:

[tex]\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \frac{382}{1198} \times 800[/tex]

Simplifying the equation:

[tex]\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx \frac{382 \times 800}{1198}[/tex]

Now, let's calculate the approximate number of visitors to The Youth Wing on Sunday:

[tex]\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx 254[/tex]

Therefore, based on the data recorded on Saturday, we can estimate that around 254 people should be expected to go to The Youth Wing on Sunday.
