The formula for the maximum likelihood estimator (MLE) of the variance of the error term can be derived by maximizing the log-likelihood function.

Set up the model and log-likelihood function

Consider a regression model where we have a dependent variable (Y) and independent variables (X) with an error term (ε). We assume that ε follows a normal distribution with mean 0 and variance σ². The model can be written as Y = βX + ε.

To derive the MLE estimator of σ², we start by writing the log-likelihood function. Since the error terms are assumed to be independent and normally distributed, the log-likelihood function can be expressed as:

ln(L) = -n/2 * ln(2π) - n/2 * ln(σ²) - (1/2σ²) * ∑(Yi - βXi)²

where n is the sample size and the sum is taken over all observations.

Maximize the log-likelihood function

To find the MLE estimator, we need to maximize the log-likelihood function with respect to σ². We do this by taking the derivative of the log-likelihood function with respect to σ^2 and setting it equal to zero.

d(ln(L))/d(σ²) = -n/(2σ²) + (1/2σ⁴) * ∑(Yi - βXi)² = 0

Simplifying this equation gives us:

σ² = (1/n) * ∑(Yi - βXi)²

Thus, the MLE estimator for the variance of the error term is the average of the squared residuals.

In a right triangle with an angle of 60° and a hypotenuse of 12 feet, we need to find the length of the side opposite the angle. The correct answer is b. x - 6√3 ft.

In a right triangle, the side opposite an angle is called the "opposite" side. To find the length of the side x, we can use the trigonometric relationship involving the angle 60°, which is known as the sine function.
The sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, we have the equation:
sin(60°) = x / 12
To solve for x, we can multiply both sides of the equation by 12:
12 * sin(60°) = x
The sine of 60° is √3 / 2, so we can substitute that value into the equation:
x = 12 * (√3 / 2)
Simplifying the expression, we get:
x = 6√3 ft
Therefore, the length of the side opposite the angle 60° is x - 6√3 ft, which matches option b.

The value of the given expression [[tex]87^3+ 13^3/87^2 -87 * 13 + 13^2[/tex]] by simplifying the numerator and denominator using suitable identities is 100.

We will first calculate the numerator:

As  ([tex]a^3[/tex] + [tex]b^3[/tex]) = (a + b)([tex]a^2[/tex] - ab + [tex]b^2[/tex]) :

[tex]87^3[/tex] + [tex]13^3[/tex] = (87 + 13)([tex]87^2[/tex] - [tex]87 * 13[/tex] + [tex]13^2[/tex])

= 100([tex]87^2[/tex] - 87 * 13 + [tex]13^2[/tex])

Now, calculate the denominator:

[tex]87^2 - 87 * 13 + 13^2[/tex]

As,([tex]a^2 -2ab +b^2[/tex]) =[tex](a - b)^2[/tex]:

[tex]87^2 - 87 * 13 + 13^2 = (87 - 13)^2[/tex]

[tex]= 74^2[/tex]

So by solving the equation further:

[tex](87^3+13^3) / (87^2- 87 * 13+13^2) = 100*(87^2- 87 *13 + 13^2)/(87^2 - 87 * 13 + 13^2)[/tex]

As we can see the numerator and denominator are the same expressions ([tex]87^2 - 87 * 13 + 13^2[/tex]). so, they cancel each other:

[tex](87^3 + 13^3) / (87^2 - 87 * 13 + 13^2) = 100[/tex]

So, the value of the given expression is 100.

Answer:

yes

Step-by-step explanation:

The value of a computer is decreasing at a rate that is proportional at any time to the value of the computer at that time The computer is worth 8850 initially, and it is worth S306 after 2 years. Then $66 will the computer be worth after 5 years.

To solve this problem, we can use the concept of exponential decay, where the value of the computer decreases exponentially over time.

Let's denote the value of the computer at any time t as V(t). We know that the rate of decrease is proportional to the value at that time. This can be expressed as:

dV/dt = k × V(t)

where dV/dt represents the rate of change of V with respect to t, and k is the proportionality constant.

To find the value of k, we can use the initial condition. The computer is worth 8850 initially, so we have:

V(0) = 8850

After 2 years, the computer is worth $306, so we have:

V(2) = 306

Now we can solve for k. Integrating the differential equation, we get:

∫(1 / V(t)) dV = ∫k dt

ln(V(t)) = kt + C

Taking the exponential of both sides, we have:

V(t) = e^(kt+C)

Since V(0) = 8850, we can substitute these values into the equation to solve for C:

e^(k × 0 + C) = 8850

e^C = 8850

C = ln(8850)

Now we have the equation:

V(t) = e^(kt + ln(8850))

Using the value V(2) = 306, we can substitute these values into the equation:

306 = e^(2k + ln(8850))

Taking the natural logarithm of both sides, we get:

ln(306) = 2k + ln(8850)

Solving for k:

k = (ln(306) - ln(8850)) / 2

Now, to find the value of the computer after 5 years (V(5)), we substitute t = 5 into the equation:

V(5) = e^(5k + ln(8850))

Calculating the value using the previously found value of k:

V(5) = e^(5 × [(ln(306) - ln(8850)) / 2] + ln(8850))

After evaluating this expression, we find that the value of the computer after 5 years is approximately $66. Therefore, the correct answer from the provided options is $66.

Mr. Alvarez can make a total of 18 complete pillows with 12.5 yards of fabric.

To determine the number of complete pillows that can be made with 12.5 yards of fabric, we need to divide the total fabric by the amount of fabric required for each pillow.

Each pillow requires 2/3 of a yard of fabric.

To calculate the number of complete pillows, we divide the total fabric available by the fabric required per pillow:

Number of pillows = Total fabric / Fabric required per pillow

Number of pillows = 12.5 yards / (2/3) yards

To divide by a fraction, we multiply by its reciprocal:

Number of pillows = 12.5 yards * (3/2) yards

Calculating this, we have:

Number of pillows = (12.5 * 3) / 2

Number of pillows = 37.5 / 2

Number of pillows = 18.75

Since we can't have a fraction of a pillow, we need to round down to the nearest whole number ≈ 18

The similarity dimension of the Cantor point set is approximately 0.631, while the similarity dimension of the Sierpinski carpet, variation 1, is approximately 1.893.

Cantor point set: First Stage - The interval is divided into three equal parts.

Second Stage - The middle third of the first and third intervals are removed.

Third Stage - The middle third of the remaining intervals is removed.

This process is continued infinitely to create the Cantor set. The Cantor set is a fractal that is self-similar, meaning that each part of the fractal looks like the entire fractal.

To find the similarity dimension of the Cantor set, we will use the following formula:

log(2)/log(3) ≈ 0.631

log(8)/log(3) ≈ 1.893

The similarity dimension of the Cantor point set is approximately 0.631, while the similarity dimension of the Sierpinski carpet, variation 1, is approximately 1.893.

The two positive real numbers with a product of 11 that have the smallest possible sum are √11 and √11. In decimal form, these numbers are approximately 3.3166 and 3.3166.

To determine two positive real numbers whose product is 11 and have the smallest possible sum, we can use the concept of the arithmetic mean-geometric mean inequality.

Let the two numbers be x and y.

We have the following conditions:

1. xy = 11 (product of the two numbers is 11)

2. x > 0, y > 0 (both numbers are positive)

According to the AM-GM inequality, the arithmetic mean of two numbers is always greater than or equal to the geometric mean of those numbers.

Using this inequality, we have:

(x + y)/2 ≥ √(xy)

Substituting the value of xy as 11, we get:

(x + y)/2 ≥ √11

To minimize the sum (x + y), we need to make it as close as possible to the right side of the inequality.

This occurs when equality holds, that is, when:

x = y = √11

So, the answer is approximately (3.3166, 3.3166).
