Answer:

Step-by-step explanation:

On the Navajo Reservation, a random sample of 218 permanent dwellings in the Fort Defiance region showed that 60 were traditional Navajo hogans. In the Indian Wells region, a random sample of 139 permanent dwellings showed that 19 were traditional hogans. Let p1 be the population proportion of all traditional hogans in the Fort Defiance region, and let p2 be the population proportion of all traditional hogans in the Indian Wells region.

(a) Find a 95% confidence interval for p1 – p2. (Use 3 decimal places.)

lower limit

upper limit

(b) Examine the confidence interval and comment on its meaning. Does it include numbers that are all positive? all negative? mixed? What if it is hypothesized that Navajo who follow the traditional culture of their people tend to occupy hogans? Comment on the confidence interval for p1 – p2 in this context.

Because the interval contains only positive numbers, we can say that there is a higher proportion of hogans in the Fort Defiance region.Because the interval contains both positive and negative numbers, we can not say that there is a higher proportion of hogans in the Fort Defiance region. We can not make any conclusions using this confidence interval.Because the interval contains only negative numbers, we can say that there is a higher proportion of hogans in the Indian Wells region.

Answer:

The surface area of the net shown is: 88 \(in^2\)

Step-by-step explanation:

Break up the different shapes in the net:

Let's take the big square first:

It has a side of 5in and a base of 4in.

We multiply both these values to get 20\(in^2\)

Lets look at the small rectangular box now:

It has a side of 3in and a base of 4in.

We multiply both these values to get 12\(in^2\)

There are two big squares so we add up their surface areas:

20\(in^2\) + 20\(in^2\) = 40\(in^2\)

There are 4 small rectangular squares so we add up their surface areas:

12\(in^2\) + 12\(in^2\) + 12\(in^2\) + 12\(in^2\) = 48\(in^2\)

Now we add up the big square and small rectangular squares values:

40\(in^2\) + 48\(in^2\) = 88\(in^2\)

Therefore the answer is 88\(in^2\)

Complete Question

Evaluate the Fermi function for an energy kT above the Fermi energy. Find the temperature at which there is a 1% probability that a state, with an energy 0.5 eV above the Fermi energy, will be occupied by an electron.

Answer:

a

The Fermi function for the energy KT is  \(F(E_o) = 0.2689\)

b

The temperature is  \(T_k = 1261 \ K\)

Step-by-step explanation:

From the question we are told that

   The energy considered is  \(E = 0.5 eV\)

Generally the Fermi  function is mathematically represented as

       \(F(E_o) = \frac{1}{e^{\frac{[E_o - E_F]}{KT} } + 1 }\)

    Here K is the Boltzmann constant with value \(k = 1.380649 *10^{-23} J/K\)

            \(E_F\)  is the Fermi energy

            \(E_o\)  is the initial energy level which is mathematically represented as

     \(E_o = E_F + KT\)

So

     \(F(E_o) = \frac{1}{e^{\frac{[[E_F + KT] - E_F]}{KT} } + 1}\)

=>   \(F(E_o) = \frac{1}{e^{\frac{KT}{KT} } + 1}\)

=>   \(F(E_o) = \frac{1}{e^{ 1 } + 1}\)

=>   \(F(E_o) = 0.2689\)

Generally the probability that a state, with an energy 0.5 eV above the Fermi energy, will be occupied by an electron is mathematically represented by the  Fermi  function as

     \(F(E_k) = \frac{1}{e^{\frac{[E_k - E_F]}{KT_k} } + 1 } = 0.01\)

Here\(E_k\) is that energy level that is  0.5 ev above the Fermi energy  \(E_k = 0.5 eV + E_F\)

=>   \(F(E_k) = \frac{1}{e^{\frac{[[0.50 eV + E_F] - E_F]}{KT_k} } + 1 } = 0.01\)

=>   \(\frac{1}{e^{\frac{0.50 eV ]}{KT_k} } + 1 } = 0.01\)

=>   \(1 = 0.01 * e^{\frac{0.50 eV ]}{KT_k} } + 0.01\)

=>   \(0.99 = 0.01 * e^{\frac{0.50 eV ]}{KT_k} }\)

=>   \(e^{\frac{0.50 eV ]}{KT_k} } = 99\)

Taking natural  log of both sides

=>   \(\frac{0.50 eV }{KT_k} } =4.5951\)

=>    \(0.50 eV =4.5951 * K * T_k\)

Note eV is electron volt and the equivalence in Joule is     \(eV = 1.60 *10^{-19} \ J\)

So

     \(0.50 * 1.60 *10^{-19 } =4.5951 * 1.380649 *10^{-23} * T_k\)

=>   \(T_k = 1261 \ K\)

Answer:

  A: 8x +24

  B: not equivalent for any value of x

Step-by-step explanation:

Part A:

The factor of 4 on the outside of parentheses multiplies each term inside:

  M = 4(2x) +4(6)

  M = 8x +24 . . . . . expression equivalent to M

__

Part B:

Expressions M and N are not equivalent for any value of x. They are equivalent if their difference is zero or can be made to be zero. Subtracting N from M, we find the difference to be ...

  M -N = (8x +24) -(8x +10) = 14

There is no value of x that will make the difference of 14 become zero.

Answer:

20% of the Congress is made of Senators.

Step-by-step explanation:

Our whole here is 500, since the House of Representatives and Senate combined would have 500 members in this case. So, we now need to find out how many senators there are.

\(2\) x \(50\) = \(100\)

Now, since we know the fact that there are 100 senators in Congress, we will find out what percent of 500 is 100.

100 = 20% of 500. To check, we will multiply 5 by 100. We get 500.

Therefore, the answer is 20%.

Answer:

A. True.

Step-by-step explanation:

To get the standard error of the mean, you need to do the sample standard deviation over the square root of the number of samples, n.

In this case, n = 100. The standard deviation is 12. To get the SAMPLE standard deviation, you do the population standard deviation over the square root of n. That is 12 / sqrt(100) = 12 / 10 = 1.2.

So, to get the standard error: 1.2 / sqrt(100) = 1.2 / 10 = 0.12.

The standard error of the mean is, indeed, 0.12, so the statement is A. True.

Hope this helps!

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

According to the triangle Inequality theorem, any two triangle sides must add up to more than the third side's length.

You may get the potential length of a triangle by multiplying the sum of two sides by the difference between two sides.

Therefore,

Let x is the possible length of the third side of a triangle.

Step-by-step explanation:

Given a tangent segment of length 24, and a secant segment from the same point with an external length of 12 and a total length of (12+x), you want to find the value of x.

The product of lengths from the common point to the two intersections with the circle are the same for both segments. In the case of the tangent, the two intersections with the circle are the same point, so the square of the length is used.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

Value of LN = 19 units

Step-by-step explanation:

Given:

LN = 3 + 8x

Find:

Value of LN

Computation:

We know that LM + MN = LN

So,

8 + 6x - 1 = LN

So,

3 + 8x = 8 + 6x - 1

3 + 8x = 7 + 6x

8x - 6x = 7 - 3

2x = 4

x = 2

So,

LN = 3 + 8x

LN = 3 + 8(2)

LN = 3 + 16

LN = 19

\(16^2-(\dfrac{x}{2})^2=(16+\dfrac{x}{2})(16-\dfrac{x}{2})\)

Step-by-step explanation:

The given expression is : \(256-\dfrac{x^2}{4}\).

We need to factorize it.

We know that, 16² = 256

So,

\(256-\dfrac{x^2}{4}=(16)^2-(\dfrac{x}{2})^2\)

We know that, \(a^2-b^2=(a-b)(a+b)\)

\(16^2-(\dfrac{x}{2})^2=(16+\dfrac{x}{2})(16-\dfrac{x}{2})\)

Hence, this is the required solution.
