The maximum likelihood estimator (MLE) for a single observation from a Bernoulli population, where the mean is known to be restricted to p [1/3, 2/3], is p = 0.

The maximum likelihood estimator (MLE) for a single observation from a Bernoulli population with a known mean restriction p [1/3, 2/3] can be found by maximizing the likelihood function.

In this case, the likelihood function can be defined as the probability of obtaining the observed value given the parameter p. Since the population follows a Bernoulli distribution, the likelihood function can be expressed as:

\(L(p) = p^x * (1-p)^(1-x)\)

where x is the observed value (0 or 1).

To find the MLE, we need to find the value of p that maximizes the likelihood function. Taking the derivative of the log-likelihood function with respect to p and setting it equal to zero, we can solve for the MLE.

The log-likelihood function for a single observation from a Bernoulli distribution is:

\(log L(p) = x * log(p) + (1-x) * log(1-p)\)

Taking the derivative with respect to p:

\(d/dp (log L(p)) = (x/p) - ((1-x)/(1-p))\)

Setting it equal to zero and solving for p:

\((x/p) - ((1-x)/(1-p)) = 0\)

Simplifying the equation, we get:

\(x(1-p) - (1-x)p = 0\)

Expanding the equation further, we get:

x - px - p + xp = 0

2xp - 2p = x

Factoring out p, we get:

\(p(2x-2) = x\)

Dividing both sides by (2x-2), we get:

p = x / (2x-2)

In this case, since the mean is restricted to the range [1/3, 2/3], we need to consider the possible values of x (0 or 1) and substitute them into the equation to find the MLE.

For x = 0:

p = 0 / (2*0-2)

= 0

For x = 1:

p = 1 / (2*1-2)

= 1 / 0

= undefined

Therefore, the maximum likelihood estimator (MLE) for a single observation from a Bernoulli population, where the mean is known to be restricted to p [1/3, 2/3], is p = 0.

The required length of AD is equal to the length of BC.

A polygon with four edges, four angles, and four vertices is called a quadrilateral. The Latin terms quadri, which means four, and latus, which means side, were combined to create the English word quadrilateral. A quadrilateral is shown in the above picture as an example.

First, we draw the quadrilateral ABCD and label the given angles:

\($\begin{align*}\angle ABD &= 35^\circ \\angle BDC &= 25^\circ\end{align*}\)

Since opposite sides of quadrilateral ABCD are equal, we have:

\($\begin{align*}AB &= DC\end{align*}\)

We can use this fact to draw diagonal BD and label its length as x:

\($\begin{align*}AB &= DC \AD + DB &= BC + DB \AD &= BC\end{align*}\)

Therefore, we can conclude that:

\($\begin{align*}AD &= BC\end{align*}\)

Thus, the length of AD is equal to the length of BC.

Answer:

\(K=-3\)

Step-by-step explanation:

According to the Factor Theorem, a binomial (x - a) is a factor of a polynomial P(x) if and only if P(a) = 0.

We have the polynomial:

\(P(x)=Kx^2-x+2\)

And we want to find the value of K such that (x + 1) is a factor.

We can rewrite our factor as (x - (-1)). Thus, a = -1.

Then in orer for (x + 1) to be a factor, P(-1) must equal 0. Hence:

\(P(-1)=K(-1)^2-(-1)+2=0\)

Simplify:

\(K+1+2=0\)

Solve for K. Hence:

A basis for W¹ consists of the vectors u₁ = (1, 0, 1) and u₂ = (0, 1, 0).  a different set of vectors that form a basis for W¹.

To find a basis for the set W¹, which consists of all vectors of the form (x, y, x + y) where x and y are real numbers, we need to determine a set of linearly independent vectors that span W¹.

Let's consider three vectors in W¹:

v₁ = (1, 0, 1)

v₂ = (0, 1, 1)

v₃ = (1, 1, 2)

To check if these vectors are linearly independent, we can form a matrix with these vectors as columns and row-reduce it to echelon form:

[1 0 1]

[0 1 1]

[1 1 2]

Performing row operations:

R3 - R1 -> R3

[-1 0 1]

[0 1 1]

[0 1 1]

Now, subtracting R2 from R3:

R3 - R2 -> R3

[-1 0 1]

[0 1 1]

[0 0 0]

Since the last row of the row-reduced matrix consists of all zeros, we can see that the vectors v₁, v₂, and v₃ are linearly dependent. Hence, we need to find a different set of vectors that form a basis for W¹.

Let's consider two different vectors in W¹:

u₁ = (1, 0, 1)

u₂ = (0, 1, 0)

Now, let's check if these vectors are linearly independent:

If we set the equation au₁ + bu₂ = 0 (where a and b are scalars), we get:

a(1, 0, 1) + b(0, 1, 0) = (0, 0, 0)

This gives the system of equations:

a = 0

b = 0

Since the only solution to this system is a = 0 and b = 0, we can conclude that the vectors u₁ and u₂ are linearly independent.

Therefore, a basis for W¹ consists of the vectors u₁ = (1, 0, 1) and u₂ = (0, 1, 0).

A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?

i have:

x=30

x+y=18

that would be -12..not right?

The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Let we assume x be the time required at the time when using both machines.

Let us assume the completed job = 1

we know that

copy machine 1 will do \(x/30\) of the job

and

copy machine 2 will do \(x/18\) of the job

So, it can be like

\(\frac{x}{30} + \frac{x}{18} = 1\)

So,

18x + 30x = 540

48x = 540

x = 11.25 minutes

hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

curve C in the first quadrant from (0, 2) to (√2, √2).

What is Quadrant?

Quadrant: Each of the four quarters of a circle or instrument used for angular measurements of altitude in astronomy and navigation, typically consisting of a graduated quarter circle and a sighting mechanism.

To integrate the function f(x, y) = x^2 - y over the given curve C: x^2 + y^2 = 4 in the first quadrant from (0, 2) to (√2, √2), we can parameterize the curve C and then evaluate the line integral.

We can parameterize the curve C as follows:

x = rcos(t)

y = rsin(t)

Since the curve is defined on the circle with radius 2, we have r = 2. Thus, the parameterization becomes:

x = 2cos(t)

y = 2sin(t)

To determine the limits of integration for t, we need to find the values of t that correspond to the given points on the curve.

For the starting point (0, 2), we have:

x = 2*cos(t) = 0

Solving for t, we find t = π/2.

For the ending point (√2, √2), we have:

x = 2*cos(t) = √2

Solving for t, we find t = π/4.

Now we can calculate the line integral of f(x, y) over C using the parameterization:

∫[C] f(x, y) ds = ∫[t=π/2 to t=π/4] (x^2 - y) ||r'(t)|| dt

where ||r'(t)|| represents the magnitude of the derivative of the vector function r(t) = (x(t), y(t)).

Let's calculate the derivatives:

x'(t) = -2sin(t)

y'(t) = 2cos(t)

Therefore, ||r'(t)|| = sqrt(x'(t)^2 + y'(t)^2) = sqrt((-2sin(t))^2 + (2cos(t))^2) = sqrt(4sin(t)^2 + 4cos(t)^2) = sqrt(4) = 2.

Substituting the parameterization, limits of integration, and ||r'(t)|| into the line integral, we have:

∫[C] f(x, y) ds = ∫[t=π/2 to t=π/4] (x^2 - y) ||r'(t)|| dt

= ∫[t=π/2 to t=π/4] ((2cos(t))^2 - 2sin(t)) * 2 dt

= 2∫[t=π/2 to t=π/4] (4cos(t)^2 - 2sin(t)) dt.

Now we can evaluate this definite integral to find the value of the line integral over the given curve C in the first quadrant from (0, 2) to (√2, √2).

To find out how much Jacob earns per hour, we need to plug in the number of hours he worked into the equation y = 16.5x. Let's say Jacob worked the same number of hours as Ariana, 24 hours. So the equation becomes y = 16.5 * 24 = $396.

To find out how much more Ariana earns per hour than Jacob, we need to subtract Jacob's hourly earnings from Ariana's hourly earnings: $29.50/hour - $16.50/hour = $13.00/hour.

The answer is Option 4) two-line stanzas that slowly build suspense about the girl’s fear of the hawk.

In literature, metaphors are frequently used to evoke strong feelings and express nuanced concepts. Because they establish a clear connection between two objects, they can be more effective than similes, but they can also be trickier to understand because they depend on the reader's comprehension of the suggested meaning. On the other hand, similes are frequently used in everyday language and might have a clearer meaning.

The poem is divided into two-line stanzas, with each stanza offering a specific concept or illustration that helps to heighten the tension around the girl's hawk phobia. Up until the final stanza, where the story's climax is disclosed, each of the stanzas builds on the one before it, intensifying the situation and the girl's anxiety. The short, pointed lines that emphasise the bird's unexpected arrival and motions, as well as the poem's structure, all contribute to its tense, unsettling atmosphere.

The measures of the angles of the rhombus are as follow: m∠1 = 66°, m∠2 = 123°, m∠3 = 66 ° and m∠4 = 123°

A rhombus' opposite angles are congruent because all of its sides are congruent. Angles 1 and 3 therefore share the same measure, as do angles 2 and 4.

As a result of the fact that any quadrilateral's total angles equal 360°, we also have:

m∠1 + m∠2 + m∠3 + m∠4 = 360

Putting the given value of 114°, we get:

m∠1 + 114 + m∠3 + 114 = 360

Simplifying and solving for m∠1 and m∠3, we get:

m∠1 + m∠3 = 132

⇒ m∠1 = 132 - m∠3

Similarly, we have:

m∠2 + m∠4 = 246

⇒ m∠2 = 246 - m∠4

Since opposite angles in a rhombus are congruent, we have:

m∠1 = m∠3 and m∠2 = m∠4

Substituting these equalities, we get:

m∠1 = (132 - m∠1) and m∠2 = (246 - m∠2)

Solving for m∠1 and m∠2, we get:

⇒ m∠1 = 66°

⇒ m∠2 = 123°

Since opposite angles in a rhombus are congruent, we have:

⇒ m∠3 = m∠1 = 66°

⇒ m∠4 = m∠2 = 123°

The local maximum and minimum values of the function are as follows: maximum at (smaller x value), minimum at (larger x value), and there are no saddle points.

To find the local maximum and minimum values of the function, we need to analyze its critical points, which occur where the partial derivatives are equal to zero or do not exist.

Let's denote the function as f(x, y) = -8 - 2x + 4y - x^2 - 4y^2. Taking the partial derivatives with respect to x and y, we have:

∂f/∂x = -2 - 2x

∂f/∂y = 4 - 8y

To find critical points, we set both partial derivatives to zero and solve the resulting system of equations. From ∂f/∂x = -2 - 2x = 0, we obtain x = -1. From ∂f/∂y = 4 - 8y = 0, we find y = 1/2.

Substituting these values back into the function, we get f(-1, 1/2) = -9/2. Thus, we have a local minimum at (x, y) = (-1, 1/2).

There are no other critical points, which means there are no local maximums or saddle points. Therefore, the function has a local minimum at (x, y) = (-1, 1/2) but does not have any local maximums or saddle points.
