Explanation:

Here, we want to get the entire length of the 20 pieces

From the question, there are 20 pieces, each of 9 6/8 inches length

Janice donated 20 pants and 80 t-shirts of clothing to the Salvation Army.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Janice donates 100 items of clothing to the Salvation Army and the number of t-shirts were 4 times the number of pants.

Therefore, If the number of pants is 'x' then the number of t-shirts are '4x'.

So, x + 4x = 100.

5x = 100.

x = 20.

So, The number of pants are 20 and the number of t-shirts are 80.

The graph attached is the graph representing the cube root function y = ∛x.

The opposite of the cubic function is the cube root function. We are aware that the parent cubic function is growing, one-one, and onto, and that its form is f(x) = x³. It is a bijection as a result. As a result, its inverse function, the cube root function, is also a bijection and has the form f(x) = ∛x. The parent cubic function and parent cube root functions have the same graphs because we know that a function and its inverse function are symmetric about the line y = x.

In the question, we are asked to show the graph of y = ∛x.

Taking the function of the cube root function as y, we get f(x) = y = ∛x.

Thus, we can show the graph of the cube root function in the attached image.

========================================================

Explanation:

Refer to the diagram below. I'm using the points A,B,C,D,E to help label the triangles, and to label the angles as well.

For now, let's focus on triangle DEC.

The top most angle is given as D = 65. Note how the angles D and E are opposite the congruent lines (marked with the red single tickmarks). This means that angles D and E are congruent to one another. So E = 65 as well. This is shown in the diagram below.

For now we don't know what angle C is, so we'll call it y. More specifically, we'll make y the measure of angle DCE.

For any triangle, the three angles always add to 180

y+65+65 = 180

y+130 = 180

y = 180-130

y = 50

So angle DCE is 50 degrees.

-------------------------------

Now we move onto triangle ABC.

Because angles DCE and ACB are vertical angles, this makes angle ACB 50 degrees also. Effectively, anywhere you see a 'y' in the diagram below, replace it with 50.

So triangle ABC has the three angles y = 50, y = 50 and 7x-4

We can solve for x like so

y+y+(7x-4) = 180

50+50+(7x-4) = 180

7x+96 = 180

7x = 180-96

7x = 84

x = 84/7

x = 12

This points to choice C as the final answer.

If four friends have $525 that they want to share equally and they divide the money so that each friend gets a $100 bill, then next step will be divide the remaining money so that each friend gets a $31.25

Total money the have = $525

they divide the money so that each friend gets a $100 bill

The amount of money they split equally = 4×100

= $400

Remaining money = 525-400

= $125

Split the remaining money into 4 = 125/4

= $31.25

Hence, If four friends have $525 that they want to share equally and they divide the money so that each friend gets a $100 bill, then next step will be divide the remaining money equally so that each friend gets a $31.25

Step-by-step explanation:

when the discriminant is less than zero, then it has no real solutions. this can be written as

b²-4ac<0 has no real solutions.

Answer:

0.3846 = 38.46% probability that the subcommittee consists of 2 men and 1 woman.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

To solve this question, we need to know the combinations formula and conditional probability.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

Conditional Probability

We use the conditional probability formula to solve this question. It is

\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)

In which

P(B|A) is the probability of event B happening, given that A happened.

\(P(A \cap B)\) is the probability of both A and B happening.

P(A) is the probability of A happening.

What is the probability that the subcommittee consists of 2 men and 1 woman, given that it contains both men and women?

Event A: Contains both men and woman

Event B: Consists of two men and 1 woman.

Probability of containing both men and woman:

Desired outcomes:

2 men(from a set of 6) and 1 woman(from a set of 9), or 1 men(from a set of 6) and 2 women(from a set of 9). So

\(D = C_{6,2}*C_{9,1} + C_{6,1}*C_{9,2} = \frac{6!}{2!4!}*\frac{9!}{1!8!} + \frac{6!}{1!5!}*\frac{9!}{2!7!} = 351\)

Total outcomes:

3 people from a set of 6 + 9 = 15. So

\(T = \frac{15!}{3!12!} = 455\)

Probability:

\(P(A) = \frac{D}{T} = \frac{351}{455} = 0.7714\)

Intersection of events A and B:

Intersection between both men and women, and 2 men and 1 woman, is 2 man and 1 women. So

Desired outcomes:

2 men(from a set of 6) and 1 woman(from a set of 9).

\(D = C_{6,2}*C_{9,1} = 135\)

Total outcomes:

3 people from a set of 6 + 9 = 15. So

\(T = \frac{15!}{3!12!} = 455\)

Probability:

\(P(A \cap B) = \frac{D}{T} = \frac{135}{455} = 0.2967\)

Desired probability:

\(P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2967}{0.7714} = 0.3846\)

0.3846 = 38.46% probability that the subcommittee consists of 2 men and 1 woman.

x⁴ - 8x² + 17 is the function that represents the fog(x).

To find fog(x), we first need to find g(f(x)), which means we need to substitute the expression for f(x) into the expression for g(x):

g(f(x)) = g(x² - 4)

Now, we can substitute the expression for g(x) into the above expression:

g(f(x)) = (x² - 4)² + 1

Expanding the squared term, we get:

g(f(x)) = x⁴ - 8x² + 17

Therefore, fog(x) = g(f(x)) = x⁴ - 8x² + 17.

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

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

=>   \(T_k = 1261 \ K\)

Thanh's cost per month (four weeks) will be $300.00.The given fixed rate for Thanh is $49.00 per week. Thanh also pays $14.00 per week for the optional insurance and $12.00 weekly on gas.

To find Thanh's cost per month (four weeks), we need to multiply his weekly cost by 4.We can use the formula below to calculate Thanh's monthly cost.

Total weekly cost = Fixed rate + Insurance cost + Gas cost

Total weekly cost = $49.00 + $14.00 + $12.00

Total weekly cost = $75.00

The cost for Thanh per month (four weeks) = Total weekly cost × 4

Cost for Thanh per month (four weeks) = $75.00 × 4

Cost for Thanh per month (four weeks) = $300.00

Therefore, Thanh's cost per month (four weeks) will be $300.00.
