the first term of arithmetic sequence is 4. We know that nth term of arithmetic sequence is given by Tn = a + (n-1) d, Where, Tn = nth term a = first term d = common difference.

Given :

Tenth term = 73 / 2 and Second term = 9 / 2

We know that nth term of arithmetic sequence is given by Tn = a + (n-1) d,

Where, Tn = nth term a = first term d = common difference

Let's find the common difference:73/2 = a + 9d  ... (i)9/2 = a + d  ... (ii)

By solving equation (i) and (ii) ,we can find the value of a

Let's subtract equation (ii) from equation (i)73/2 - 9/2 = 8da = 32/8 = 4

Hence, the first term of arithmetic sequence is 4.

Critical points of the function are given as:f'(x) = 39x^2 - 8x + 12 = 0Solving the above equation, we get:x = (-(-8) ± √((-8)^2 - 4(39)(12))) / 2(39)x = (8 ± √400) / 78x = 1/3, 4/13

We check the value of f(0), f(1/3), f(4/13), f(9).f(0) = -5f(1/3) = 1.88889f(4/13) = 2.6022f(9) = 10588

Absolute maximum value of the function is the maximum value among f(0), f(1/3), f(4/13), and f(9).

The point estimate of the difference between the population means, as calculated in your example, is indeed 15. This is obtained by subtracting the sample mean of Sample 2 from the sample mean of Sample 1. In this case, the point estimate suggests that the population mean of the first group is estimated to be 15 units higher than the population mean of the second group as follows :

Sample 1:

Sample mean ₁ = 50

Sample standard deviation ₁ = 13.1

Sample size ₁ = 2

Sample 2:

Sample mean ₂ = 35

Sample standard deviation ₂ = 11.6

Sample size ₂ = 3

The point estimate of the difference between the population means (µ₁ - µ₂) is given by:

Point Estimate = Sample mean ₁ - Sample mean ₂

             = 50 - 35

             = 15

We need to find the Taylor series for f(x) centered at the given value of a.

To find the Taylor series for ln(x) function we use the formula of the Taylor series which is:

[tex]f(x) = f(a) + f'(a)(x-a)/1! + f''(a)(x-a)^2/2! + ....+ f^n(a)(x-a)^n/n!......eqn.1[/tex]

Differentiating the given function ln(x), we get;

[tex]f'(x) = 1/x ......eqn.2\\f''(x) = -1/x^2 .......eqn.3\\f'''(x) = 2!/x^3 .....eqn.4\\f^4(x) = -3! /x^4 ....eqn.5[/tex]

Therefore, substituting the values of a, f(a), f'(a), f''(a), f'''(a) and f^4(a) in eqn.1, we get;

[tex]ln(x) = ln(4) + (1/4)(x-4) - (1/32)(x-4)^2 + (1/64)(x-4)^3 - (3/256)(x-4)^4 ......eqn.6[/tex]

The associated radius of convergence R is given by the formula;

[tex]R = lim |a_n / a_n+1 |[/tex]

where a_n is the nth term of the series.

In this case, the nth term is (x-4)^n/n!

Therefore, [tex]a_n+1 = (x-4)^(n+1) / (n+1)! and a_n = (x-4)^n/n!.[/tex]

Substituting these values in the formula, we get;

[tex]R = lim|(x-4)^n/n! x (n+1)!/(x-4)^(n+1) |[/tex]

on simplifying, we get;

[tex]R = lim |(x-4)/(n+1)|[/tex]

as n approaches, infinity, the denominator in the above equation becomes very large, and thus R approaches 0.

Hence the associated radius of convergence R is 0. Answer: [tex]ln(4) + (1/4)(x-4) - (1/32)(x-4)^2 + (1/64)(x-4)^3 - (3/256)(x-4)^4[/tex] and R = 0.

Therefore, the length of the curve defined by r(t) = 6ti^2 + tjt^3 + tk, where 0 ≤ t ≤ 1, is approximately 3.618.

To find the length of the curve given by the vector-valued function r(t) = 6ti^2 + tjt^3 + tk, where 0 ≤ t ≤ 1, we can use the arc length formula for a curve in three dimensions.

The arc length formula is given by:

L = ∫ ||r'(t)|| dt

First, we need to find the derivative of r(t):

r'(t) = d/dt (6ti^2 + tjt^3 + tk)

= 12ti^2 + 3t^2j + k

Next, we need to find the magnitude of r'(t):

||r'(t)|| = ||12ti^2 + 3t^2j + k||

= √((12t)^2 + (3t^2)^2 + 1^2)

= √(144t^2 + 9t^4 + 1)

Now, we can calculate the length of the curve using the integral:

L = ∫₀¹ √(144t^2 + 9t^4 + 1) dt

This integral can be challenging to solve analytically, so we can use numerical methods or calculators to approximate the value.

The natural and social sciences frequently utilise normal distributions to describe real-valued random variables whose distributions are unknown, which is why normal distributions are essential in statistics. The central limit theorem contributes to some of their significance. According to this statement, under some circumstances, the average of numerous samples (observations) of a random variable with finite mean and variance is itself a random variable, whose distribution converges to a normal distribution as the number of samples rises. As a result, the distributions of physical quantities, such as measurement errors, that are predicted to be the sum of numerous distinct processes frequently resemble normal distributions.

To find the coordinates of the center and the length of the radius of a circle given its equation, we need to rewrite the equation in the standard form (x - h)^2 + (y - k)^2 = r^2.

Where (h, k) represents the center of the circle and r represents the radius.

In the given equation x^2 + y^2 - 2x + 6y + 3 = 0, we can complete the square for both the x and y terms. Let's start with the x terms:

x^2 - 2x + y^2 + 6y + 3 = 0

(x^2 - 2x + 1) + (y^2 + 6y + 9) = 1 + 9

(x - 1)^2 + (y + 3)^2 = 10

Comparing this with the standard form, we can see that the center of the circle is at (1, -3) and the radius is √10.

Probability for selecting household is going to be only 46%.

To find the probability of randomly selecting a household that has one or two televisions, we need to sum the probabilities of the households with one television and two televisions.

In this case, we would sum the probabilities for P(x=1) and P(x=2).

The probability distribution provided gives us the probabilities for each number of televisions per household. Let's calculate the probability:

P(x=1) = 0.15

P(x=2) = 0.31

To find the probability of randomly selecting a household with one or two televisions, we add the probabilities together:

P(x=1 or x=2) = P(x=1) + P(x=2) = 0.15 + 0.31 = 0.46

Therefore, the probability of randomly selecting a household that has one or two televisions is 0.46 or 46%.

This means that if we were to randomly select a household from the small town, there is a 46% chance that the household will have either one or two televisions.

It is important to note that the given probability distribution should sum up to 1, which ensures that all possible outcomes are accounted for. In this case, the sum of all the probabilities is indeed 1, as 0.01 + 0.15 + 0.31 + 0.53 = 1.

By understanding the probability distribution, we can gain insights into the prevalence of different numbers of televisions in households in the small town.

In this problem, we have i.i.d. random variables X1, X2, ..., Xn with a specific density function. We are interested in estimating the parameter a using the method of moments. The method of moments involves equating the sample moments with the theoretical moments to obtain an estimate for the parameter.

The maximum likelihood estimation (MLE) of a satisfies a certain equation. The asymptotic variance of the MLE can be determined, and a sufficient statistic for a can be found.

(i) To estimate the parameter a using the method of moments, we equate the sample moments with the theoretical moments. Since we know that E(X) = 1/2 and Var(X) = 1/4(2a + 1), we can set the sample mean and sample variance equal to their respective theoretical values and solve for a.

(ii) The maximum likelihood estimation (MLE) of a can be found by maximizing the likelihood function based on the observed data. In this case, the MLE of a satisfies an equation obtained by taking the derivative of the log-likelihood function with respect to a and setting it equal to zero.

(iii) The asymptotic variance of the MLE in (ii) can be determined using the Fisher information. The Fisher information quantifies the amount of information that the data provides about the parameter. In this case, it involves taking the second derivative of the log-likelihood function with respect to a and evaluating it at the MLE.

(iv) To find a sufficient statistic for a in (i), we need to determine a statistic that captures all the information in the data regarding the parameter a. In this case, a sufficient statistic can be found using the factorization theorem or by considering the joint density function of the random variables. The specific form of the sufficient statistic will depend on the given density function and the parameter a.

Now, let's differentiate w with respect to u and v.

dw/du = d(2u² + u²v - 2v² + 3uv²)/du

      = 4u + 2uv + 3v^2

dw/dv = d(2u² + u²v - 2v² + 3uv²)/dv

      = -4v + u^2 - 4uv + 6uv

Now, we can evaluate dw/du and dw/dv at the point (u, v) = (-1/3, -3):

dw/du = 4(-1/3) + 2(-1/3)(-3) + 3(-3)²

     = -4/3 + 2/3 + 27

     = 25

and, dw/dv = -4(-3) + (-1/3)² - 4(-1/3)(-3) + 6(-1/3)(-3)

     = 12 + 1/9 + 4 - 6

     = 11 + 1/9

Therefore, at the point (u, v) = (-1/3, -3), dw/du = 25 and dw/dv = 11 + 1/9.
