The MLE of σ² is a biased estimator of σ²

The maximum likelihood estimator (MLE) of σ² is a biased estimator, we need to demonstrate that its expected value is different from the true population variance, σ².

Let's start with the definition of the MLE of σ². In the context of simple linear regression, the MLE of σ² is given by:

MLE(σ²) = SSE/n

where SSE represents the sum of squared errors and n is the number of observations.

The expected value of the MLE, we need to take the average of all possible values of MLE(σ²) over different samples.

E(MLE(σ²)) = E(SSE/n)

Since the expectation operator is linear, we can rewrite this as:

E(MLE(σ²)) = 1/n × E(SSE)

Now, let's consider the expected value of the sum of squared errors, E(SSE). In simple linear regression, it can be shown that:

E(SSE) = (n - k)σ²

where k is the number of predictors (including the intercept) in the regression model.

Substituting this result back into the expression for E(MLE(σ^2)), we get:

E(MLE(σ²)) = 1/n × E(SSE)

= 1/n × (n - k)σ²

= (n - k)/n × σ²

Since (n - k) is less than n, we can see that E(MLE(σ²)) is biased and different from the true population variance, σ².

Therefore, we have shown that the MLE of σ² is a biased estimator of σ².

Answer:

The measures are 108 deg and 72 deg.

Step-by-step explanation:

The larger angle has measure x.

The smaller angle has measure (2/3)x.

They are supplementary, so the sum of their measures is 180 degrees.

x + (2/3)x = 180

(3/3)x + (2/3)x = 180

(5/3)x = 180

(3/5) * (5/3)x = (3/5) * 180

x = 108

(2/3)x = 2/3 * 108 = 72

Answer: The measures are 108 deg and 72 deg.

Answer:

132 minutes

Step-by-step explanation:

If you see that 1 mile is 22 minutes, then you would know 2 miles is double, three miles is triple and so on. So you would do 22x6 for the six miles to get your answer of 132, or you can even do 22 plus 22 six times.

Answer:

132 minutes = 2 hours and 12 minutes

Step-by-step explanation:

22 x 6 = 132 (minutes)

to find it in hours:

132 divided by 60 = 2.2 (2 hours)

2 x 60 = 120

132 - 120 = 12 (minutes)

Answer:

34 units

Step-by-step explanation:

The perimeter of a triangle is given by the sum of the lengths of its three sides.

So if the perimeter is 68 units and the sides measure x, 2x and 3x, we have that:

x + 2x + 3x = 68

6x = 68

x = 68/6 units

Now with the value of x we can find the length of EO:

EO = 3x

EO = 3 * (68/6)

EO = 68/2 = 34 units

Answer:

x = 25

y = 6

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

2x and 50 are opposite angles,

2x = 50

Divide 2 on both sides,

x = 50 / 2

x = 25

In a parallelogram opposite sides are equal.

y + 5 and 11 are opposite sides,

y + 5 = 11

y = 11 - 5

y = 6

Answer:

x=25

y=6

Step-by-step explanation:

from the diagram,

2x= 50(opposite angles of a parallelogram)

2x= 50

dividing bothsides by 2

2x/2=50/2

x= 25

then,

y+5=11(opposite sides of a parallelogram)

y= 11-5

y= 6

Number of steps that he needed to walk to achieve the goal is 3141 steps

The goal of the Jayden = 10000 steps

The number of steps that he walked = \((\frac{1}{19} )^{-3}\) steps

Here we have to convert  the given number of steps to the suitable form for calculation

The number of steps that he walked

\((\frac{1}{19} )^{-3}\) steps = \(19^3\) steps

Find the power of the number

\(19^3\) steps = 6859 steps

Number of steps that he needed to walk to achieve the goal = The goal of the Jayden - The number of steps that he walked

Substitute the value in the equation,

Here we have to sue the subtraction

Number of steps that he needed to walk to achieve the goal  = 10000 - 6859

= 3141 steps

Hence, number of steps that he needed to walk to achieve the goal is 3141 steps

The counterclockwise circulation around c is 12 and the outward flux through c is zero.

Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.

In this case,

we have a field f=(7x−4y)i+(9y−4x)j and

a square curve c bounded by x=0, x=4, y=0, y=4.

To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.

The curl of f is given by (0,0,3), so the line integral evaluates to 12.

To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.

Answer:

Step-by-step explanation:

m∠R = 180° - 110° [Linear pair of angles are supplementary]

m∠R = 70°

m∠S = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠P + m∠R + m∠S = 180°

m∠P + 70° + 45° = 180°

m∠P = 180 -115

        = 65°

Therefore, m∠A = m∠P = 65° [Vertically opposite angles]

By triangle sum theorem,

m∠B + m∠S + m∠T = 180°

m∠B + 45° + 65° = 180°

[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]

m∠B = 180° - 110° = 70°

m∠C + m∠B = 180° [Linear pair of angles are supplementary]

m∠C = 180° - 70° = 110°

m∠D + m∠T = 180° [Linear pair of angles are supplementary]

m∠D + 65° = 180°

m∠D = 115°

The cost to make 63 doughnuts per day is $101.5 and the cost to make 76 doughnuts is $108. We need to calculate the cost of producing one doughnut.

Using the given data,

Cost for 76 doughnuts - Cost for 63 doughnuts

= $108 - $101.5

= $6.5Cost per doughnut

= $\frac{6.5}{76-63}$

= $\frac{6.5}{13}$ = $0.5$

Now,

the cost to produce 258 doughnuts is $101.5 + (258 * 0.5) = $230.5.

Daily profit can be calculated by multiplying the number of doughnuts sold with the price of each doughnut, then subtracting the total cost of producing all the doughnuts.

Daily profit = (Number of doughnuts sold) * (Price per doughnut) - (Total cost to produce the doughnuts)

We are given that each doughnut sells for $2 and

we have calculated that the total cost to produce 258 doughnuts is $230.5.Daily profit = (258) * (2) - (230.5)

= $285.5.

Hence, the daily profit when 258 doughnuts are made and sold is $285.5.

Answer:

The missing fraction is 6/12

(you can further simplify this but the question requires that you don't do that)

Step-by-step explanation:

To add fractions easily, their denominators should have the same value, so the denominator should be 12,

Then, to get 16 in the numerator, we need to find a number that on adding to 10, gives 16, or,

10 + x = 16

x = 16 - 10

x = 6

So, the numerator should be 6

so we get the fraction, 6/12

We can also solve it in an alternate way,

\(10/12 + x = 16/12\\x = 16/12 - 10/12\\x = (16-10)/12\\x = 6/12\)

This integral represents the sum of the volumes of all the infinitesimally thin cylindrical shells that make up the solid.

To set up the integral for the volume of the solid obtained by rotating the region bounded by the curves y = x, y = 0, and x = 4 about the line x = 8, we can use the method of cylindrical shells.

First, let's draw a rough sketch of the region and the axis of rotation:

```

|       |           |

|       |           |

|       |

+------------------------ <-- x = 8

```

The region bounded by y = x, y = 0, and x = 4 is a triangle with a right angle at the origin.

To set up the integral, we consider an infinitesimally thin cylindrical shell with radius r, height h, and thickness Δy. The volume of this shell can be approximated as the product of its circumference, height, and thickness.

The radius of the shell, r, is the distance from the axis of rotation (x = 8) to the curve y = x. Since x = y for the region, r = 8 - y.

The height of the shell, h, is the difference between the x-values at the top and bottom of the region. In this case, h = 4 - 0 = 4.

The thickness of the shell, Δy, represents an infinitesimally small change in the y-direction.

Therefore, the volume of the shell is approximately given by V_shell = 2πr * h * Δy.

To find the total volume, we integrate this expression over the range of y-values that span the region. In this case, the integral is set up as follows:

∫[0, 4] 2π(8 - y) * 4 * dy

This integral represents the sum of the volumes of all the infinitesimally thin cylindrical shells that make up the solid. By evaluating this integral, you can find the exact volume of the solid obtained by rotating the region bounded by y = x, y = 0, and x = 4 about the line x = 8.

When measuring the effects of a new diuretic medication, hourly urine output represents the ratio level of measurement.

What is ratio level of measurement?

Ratio level of measurement is a type of measurement that features a true zero point, meaning that the value 0 represents the absence of the characteristic being measured.

Some examples of ratio level measurements include weight, height, length, distance, speed, and many others. In this case, the hourly urine output of subjects is measured to determine the effects of a new diuretic medication.

The hourly urine output is a ratio measurement because it has a true zero point, which is the absence of urine output. In other words, if there is no urine output, the value would be 0, which represents the absence of the characteristic being measured.

One advantage of installing a copper wire twisted-pair cable versus a fiber optic cable is the lower cost.

The cost advantage of copper wire twisted-pair cable over fiber optic cable stems from several factors. Firstly, the materials used in copper wire cables are less expensive than the specialized materials used in fiber optic cables.

Copper wire is readily available and widely used in various industries, resulting in lower production costs. Fiber optic cables, on the other hand, require the use of costly materials such as glass or plastic fibers, which need to be carefully manufactured to ensure optimal performance.

Additionally, the installation and maintenance of copper wire cables are generally more straightforward and less expensive compared to fiber optic cables.

Copper cables can be easily terminated and connected using standard connectors, while fiber optic cables require more precise fusion splicing or mechanical connectors, which can increase installation costs.

Copper wire cables are a popular choice for short-distance communication due to their cost-effectiveness.

The coordinate vector of p(t) = -7 + 12t - 14t² relative to the basis B = (1 + t², 2 - t², 1 + t + t²) is [-7, 12, -14].

To find the coordinate vector of p(t) relative to the given basis B, we need to express p(t) as a linear combination of the basis vectors. The coordinate vector represents the coefficients of the linear combination.

The basis B consists of three vectors: (1 + t², 2 - t², 1 + t + t²).

We want to find the coefficients that satisfy p(t) = c₁(1 + t²) + c₂(2 - t²) + c₃(1 + t + t²), where c₁, c₂, and c₃ are the coefficients to be determined.

Comparing the coefficients of each term, we have:

-7 = c₁

12t = -c₁t² + c₂t² + c₃t

-14t² = c₁t² - c₂t² + c₃t²

Simplifying these equations, we find:

c₁ = -7

12 = (c₂ - c₁)t

-14 = (c₃ - c₁)t²

From the first equation, we obtain c₁ = -7.

Substituting this value into the second equation, we get 12 = (c₂ + 7)t. Thus, c₂ = 12/t - 7.

Similarly, substituting c₁ = -7 into the third equation, we get -14 = (c₃ + 7)t², which gives us c₃ = -14/t² - 7.

Therefore, the coordinate vector of p(t) relative to the basis B is [-7, 12/t - 7, -14/t² - 7].

The graph of N(t) = 75t + 120 is a straight line with a positive slope of 75. It intersects the y-axis at (0, 120) and has a y-intercept of -8/5. As t approaches infinity, N(t) increases without bound, indicating a positive relationship between the number of days of training and the average number of components assembled per day.

To sketch the graph of N(t) = 75t + 120, we can plot points on the coordinate plane by substituting different values of t into the equation.

For example, when t = 0, N(0) = 75(0) + 120 = 120. So, we have the point (0, 120).

When t = 1, N(1) = 75(1) + 120 = 195. So, we have the point (1, 195).

We can continue to calculate more points using different values of t.

The intercept is when N(t) = 0:

0 = 75t + 120

-120 = 75t

t = -120/75

t = -8/5

So, we have the intercept (0, -8/5).

To find the asymptote, we need to check what happens to N(t) as t approaches infinity. As t becomes larger and larger, the constant term 120 becomes less significant compared to the term 75t. Therefore, as t approaches infinity, N(t) approaches infinity as well.

In practical terms, this means that as the number of days of training (t) increases, the average number of components assembled (N) per day also increases. However, it is important to note that this is based on past records and the actual performance of new employees may vary. The equation provides an average trend and does not account for individual variations or other factors that may affect productivity.
