If the random variable X has the binomial, bin(n, p) distribution, does the unbiased estimator of (1/p)exist? Explain your answer clearly by providing the step-by-step solution.

Answers

The unbiased estimator of 1/p does not exist.

What is an unbiased estimator?

An estimate that deviates from the genuine population value is said to be biased. If the kind and extent of the bias are known, a biased sample may still be informative. When a sample's value matches the actual value of a population parameter, that is an unbiased estimator.

Given:

If the random variable X has the binomial.

1/p = 1 /{1-(1-p)} = 1 + (1-p) + (1-p)²/2! + ....

And let an unbiased estimator of 1/p exist.

[tex]\sum^n_k_=_0T(k)(^n_k)p^k(1-p)^k[/tex] = 1 + (1-p) + (1-p)²/2! + ....

The above series is finite on the LHS and infinite power series on the RHS.

That is contradiction.

The basic idea is that an unbiased estimator of 1/p would have to have the property that its expected value as a function of p would have to tend to infinity as p tends to 0.

But since Ep[U(x)] is bounded above by some function of n that is independent of p, no such estimator can exist.

Therefore, the unbiased estimator 1/p can not exist.

what is the answer for x?​

Answers

The answer of x is 100 degree.We can find by using percentage formula.

What do we mean by percentage?

Percentage is a value or ratio that shows a fraction of 100. Percent means per 100. It does not have any units.If we have to calculate percent of a number then we  divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

What is the percentage formula?

The formula used to calculate percentage is: (value/total value)×100%.The most basic application of percentages is to compare one quantity against another. When we want to talk about data in this way we use it with the word, "of." To use this data as an example, we would say, for example, "25% of people prefer cake," as in this example.

Now we have

100 = x of 100%

100= x * 100/100

100=  x

Hence we can calculate value of x.

A rectangle off the length (x+2) cm and breadth (x)cm has an area of 15cm².find the va of x hence the perimeter of the rectangle.​

Answers

Answer:

The area of a rectangle is given by the formula:

area = length * breadth

In this case, the length of the rectangle is (x+2) cm and the breadth is (x) cm, so the area is:

area = (x+2) cm * (x) cm

= x^2 + 2x cm^2

We know that the area of the rectangle is 15 cm^2, so we can set up the following equation:

x^2 + 2x cm^2 = 15 cm^2

We can solve for x by using the quadratic formula:

x = (-2 +/- sqrt(4 - 41(-15))) / (2*1)

= (-2 +/- sqrt(64)) / 2

= (-2 +/- 8) / 2

= (-4, 2)

We have two solutions for x, so we need to consider both of them to find the dimensions of the rectangle.

If x=-4, then the length of the rectangle is (x+2) cm = (-4+2) cm = (-2) cm and the breadth is (x) cm = (-4) cm. Since the length and breadth of a rectangle must both be positive, this solution is not valid.

If x=2, then the length of the rectangle is (x+2) cm = (2+2) cm = 4 cm and the breadth is (x) cm = 2 cm. These dimensions give us a valid rectangle with an area of 15 cm^2.

The perimeter of the rectangle is the sum of all four sides, so the perimeter is 2 cm + 2 cm + 4 cm + 4 cm = 12 cm.

Therefore, the value of x that gives us a rectangle with an area of 15 cm^2 and a perimeter of 12 cm is x=2.

We want to find the number of positive 10 digit numbers that can be made using seven ones and three zeros.

Now, the leftmost position digit cannot be 0 and as such it is 1, due to the fact that there are no other possibilities.

The rightmost position therefore must be 0 in order to fill the need for an even number.

Thus, we have 8 remaining positions that we need to fill with six ones and two zeros using an arbitrary manner.

According to question as both side are equal so it is an isosceles triangle and the value of X is 18.

What are the properties of Isosceles Triangle?

An isosceles triangle is a triangle with two sides of equal length. Some properties of an isosceles triangle include:

The two equal sides are called the legs of the triangle and the remaining side is called the base.The angle between the legs is always equal to the angle between the base and one of the legs.The altitude (perpendicular line segment from a vertex to the opposite side) bisects the base of the triangle.The median (line segment from a vertex to the midpoint of the opposite side) and the altitude from the same vertex to the opposite side are also congruent.The circumcenter (center of the circle that passes through all three vertices) of an isosceles triangle is always located at the midpoint of the line connecting the two vertices of the congruent sides.The line that is bisecting the angle between the congruent sides (also known as the angle bisector) also bisects the side opposite to that angle.

so In this triangle ,

The mid point on horizontal side is given and 5m line cut the mid point of both the sides.

both side are equal as it is an isosceles triangle.

and given in the question,

side/2 =9

and  one side is equal to x.

and both sides are equal,

therefore

side = 9*2 = 18

We have,

Right triangle ABC.

AB = 6

BC = 10

AC = 8

In order for the triangle to be a right triangle it must satisfy the Pythagorean theorem.

ln 4 - ln x = 2
Solve for x
Show all steps

Answers

Answer:

To solve this equation, we first need to isolate the ln term on one side of the equation. To do this, we can subtract ln 4 from both sides to get:

ln 4 - ln x - ln 4 = 2 - ln 4

This simplifies to:

-ln x = 2 - ln 4

Next, we can add ln 4 to both sides to get:

-ln x + ln 4 = 2

This simplifies to:

ln 4 - ln x = 2

Now, we can apply the identity ln a - ln b = ln(a/b) to both sides of the equation to get:

ln(4/x) = 2

To solve for x, we can apply the inverse logarithm function (exp) to both sides:

4/x = exp(2)

This simplifies to:

x = 4/exp(2)

Finally, we can evaluate this to get the value of x:

x = 4/exp(2) = 4/7.38905609893065

So the solution is x = 4/7.38905609893065.

Answer: 24 units.

Step-by-step explanation: To find the perimeter of a triangle, you need to add the length, width, and hypotenuse. The length and width are provided, but we need to find the hypotenuse of the triangle. To do this, we need to use the Pythagorean Theorem.

The Pythagorean Theorem is basically a^2 + b^2 = c^2 where a and b are the legs of the triangle and c is the hypotenuse (also known as the triangle's longest side). However, whatever answer you get needs to be square-rooted, which is your complete answer. Let's say that the side that's 6 units is leg a and the side that's 8 units is leg b.

6^2 + 8^2 = c^2

36 + 64 = 100

√100 = 10.

Now that we know the hypotenuse, we can add it to our other two sides.

6 + 8 + 10 = 24.

Therefore, 24 is your answer.

What if I only know the length of the shorter side consider the triangle equilateral triangle than determine the values of n and m without using a calculator

Answers

Answer: An equilateral triangle is a three-sided polygon with three equal sides and three equal angles of 60 degrees each. If you know the length of one of the sides of an equilateral triangle, you can use the formula for the area of an equilateral triangle to determine the values of n and m. The formula for the area of an equilateral triangle is:

Area = (sqrt(3)/4) * s^2

where s is the length of one of the sides of the triangle.

To determine the values of n and m, you can rearrange the formula to solve for s. For example, if you know that the area of the triangle is n and the value of m is the length of one of the sides of the triangle, you can rearrange the formula to solve for s:

s = sqrt(4n/sqrt(3))

Then, you can use the value of s to determine the value of m.

If n is a two-digit number, what is the sum of the digits of 99×n?

Answers

Answer: The sum of the digits of 99 × n is 27 - 10 = 17.

Step-by-step explanation:

To find the sum of the digits of 99 × n, we can use the fact that 99 × n = 100 × n - n. The sum of the digits of 100 × n is simply n, since the hundreds digit is zero. Therefore, the sum of the digits of 99 × n is equal to the sum of the digits of n - n, which is simply zero.

For example, if n = 37, then 99 × n = 99 × 37 = 3,699. The sum of the digits of 3,699 is 3 + 6 + 9 + 9 = 27. The sum of the digits of 37 is 3 + 7 = 10. Therefore, the sum of the digits of 99 × n is 27 - 10 = 17.
