Answer:

61

Step-by-step explanation:

The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.

The formula for this question would be \(c=\sqrt{a^2 + b^2}\)

Since we know that a = 11 and b = 60, we can do the following and substitute :

\(c = \sqrt{11^2 + 60^2}\)

11 squared is 121

60 squared is 3600

Now we need to add the two number together :

121 + 3600

3721

Since this number is under the square root, we have to square root it. :

\(\sqrt{3721}\)

61

Therefore c is equal to 61.

Answer: C) \(3x^3+ 6x^2 + 5x +10\)

Step-by-step explanation:

Using the FOIL method since we're multiplying two binomials. We get...

F: Firsts

\(3x^2(x)\)=\(3x^3\)

O: Outside

\(3x^2(2) = 6x^2\)

I: Insides

\(5(x) = 5x\)

L: Lasts

\(5(2) = 10\)

Put them together and we have \(3x^3+ 6x^2 + 5x +10\)! These two are both equivalent since the form given in the question was factored form and this form is just the same thing expanded!

Answer:

C

Step-by-step explanation:

The all out cost capability is C(x) = 2x + 110. The dollar amounts for the cost, revenue, and profit, as well as the number of units, are x.

The given minor expense (MC) for an item is MC = 2x + 5. Let's locate the function of total costs. Cost (C) = Total Cost (TC) / Number of Units (x)The total cost of 10 units is estimated to be $540, as we know from previous experience. We should substitute this worth in the above equation. C(10) = 540/10C(10) = 54Now, we should see as the proper expense. When there are no units produced, the fixed cost is presented as the cost.

That is when x = 0. Let's seek it out. When x is zero, C(x) equals Fixed Cost. From the given equation, MC equals 2x + 5, and when x is zero, MC equals 2(0) + 5 = 5. Let the fixed cost be a. Then,C(x) = 2x + 5aThe complete expense capability is given by C(x) = 2x + 5a. We really want to track down a with the end goal that when x = 10, the all out cost capability is 540.C(10) = 2(10) + 5a = 54On tackling, we get,a = 22The complete expense capability is given by,C(x) = 2x + 5a = 2x + 5(22) = 2x + 110Therefore, the all out cost capability is C(x) = 2x + 110. The dollar amounts for the cost, revenue, and profit, as well as the number of units, are x.

a). The difference between the two population means is estimated at a location to be 2.7.

b). 49 different possible outcomes make up the t distribution. The margin of error at 95% confidence is 1.7.

c). The range of the difference between the two population means' 95% confidence interval is (0.0, 5.4).

d). The (0.0, 5.4) represents the 95% confidence interval for the difference among the two population means.

The variability or spread in a set of data is commonly measured by the standard deviation. The deviation between the values in the data set and the mean, or average, value, is measured. A low standard deviation, for instance, denotes a tendency for data values to be close to the mean, whereas a high standard deviation denotes a larger range of data values.

Using the equation \(x_1-x_2\), we can determine the point estimate of the difference between the two population means. In this instance, we calculate the point estimate as 2.7 by taking the mean of Sample

\(1(x_1=22.8)\) and deducting it from the mean of Sample \(2(x_2=20.1)\).

With the use of the equation \(df=n_1+n_2-2\), it is possible to determine the degrees of freedom for the t distribution. In this instance, the degrees of freedom are 49 because \(n_1\) = 20 and \(n_2\) = 30.

We must apply the formula to determine the margin of error at 95% confidence \(ME=t*\sqrt[s]{n}\).

The sample standard deviation (s) is equal to the average of \(s_1\) and \(s_2\) (3.4), the t value with 95% confidence is 1.67, and n is equal to the

average of \(n_1\) and \(n_2\) (25). When these values are entered into the formula, we get \(ME=1.67*\sqrt[3.4]{25}=1.7\).

Finally, we apply the procedure to determine the 95% confidence interval for the difference between the two population means \(CI=x_1-x_2+/-ME\).

The confidence interval's bottom limit in this instance is \(x_1-x_2-ME2.7-1.7=0.0\) and the upper limit is \(x_1+x_2+ME=2.7+1.7=5.4\).

As a result, the (0.0, 5.4) represents the 95% confidence interval for the difference among the two population means.

Answer:

Choice B

Step-by-step explanation:

The best way to compare two lines is to solve for y.

The first equation:

For \(20y-24x=-20\) the first thing we should do is add the 24x on both sides which will cancel out itself on the left side \(20y=24x-20\). Now all we have to do is divide the 20 on both sides to leave us with \(y=\frac{6}{5}-1\).

The second equation:

For \(5y-6x=-5\) the first thing we should do is add the 6x on both side which will cancel itself on the left side \(5y=6x-5\). Now all we have to do is divide the 5 on both sides to leave us with \(y=\frac{6}{5}x-1\).

Correlation is a statistical method for determining the association or relationship between two variables. To put it another way, the correlation coefficient formula facilitates the calculation of the correlation coefficient, which assesses the degree to which one variable depends on another.

The correlation coefficient is a numerical indicator of correlation. Between -1 and 1, the correlation coefficient is found. An inverse association between two variables is shown by a negative correlation coefficient. A high correlation coefficient means that the two variables directly affect one other's values. There is no association between the two variables, according to a zero-correlation coefficient.

Considering that lines m and n are parallel, we have that angles (7x - 30)º and (6x - 10)º are congruent angles, hence the value of x is of x = 20º.

The problem is incomplete, but researching it on the internet, we have that:

There are two parallel lines, and the angle of (6x - 10)º is alternate interior with the opposite angle by the same vertex of (7x - 30)º, hence they are congruent.

Congruent angles are angles that have the same measure, hence, the value of x can be found as follows:

7x - 30 = 6x - 10

7x - 6x = 30 - 10

x = 20.

The value of x is of x = 20º.

(a) To evaluate (x^2) for the ground state of the Harmonic Oscillator, we need to integrate x^2 multiplied by the square of the absolute value of the wavefunction ψ0(x).

(b) The expectation value of p^2 for the ground state of the Harmonic Oscillator is simply the eigenvalue corresponding to the momentum operator squared.

(c) By calculating the uncertainties in position (Δx) and momentum (Δp) for the ground state, we can verify that their product satisfies Heisenberg's uncertainty principle, Δx · Δp ≥ ħ/2.

(a) In the ground state of the Harmonic Oscillator, the wavefunction is given by \(\psi_0(x) = \frac{1}{\sqrt{\sigma}}e^{-\frac{x^2}{2\sigma^2}}\), where \(\sigma\) is the standard deviation.

To evaluate \((x^2)\), we need to find the expectation value of \(x^2\) with respect to the wavefunction \(\psi_0(x)\). Using the formula for the expectation value, we have:

\((x^2) = \int_{-\infty}^{\infty} x^2 \left|\psi_0(x)\right|^2 dx\)

Substituting the given wavefunction, we have:

\((x^2) = \int_{-\infty}^{\infty} x^2 \frac{1}{\sqrt{\sigma}}e^{-\frac{x^2}{\sigma^2}} dx\)

Evaluating this integral gives us the value of \((x^2)\) for the ground state of the Harmonic Oscillator.

To evaluate \(\sigma_2\), we can simply take the square root of \((x^2)\) and subtract the expectation value of \(x\) squared, \((x)^2\).

(b) To evaluate \((p^2)\), we need to find the expectation value of \(p^2\) with respect to the wavefunction \(\psi_0(x)\). However, in this case, it is clear that the ground state of the Harmonic Oscillator is an eigenstate of the momentum operator, \(p\). Therefore, the expectation value of \(p^2\) for this state will simply be the eigenvalue corresponding to the momentum operator squared.

(c) The Heisenberg's uncertainty principle states that the product of the uncertainties in position and momentum (\(\Delta x\) and \(\Delta p\)) is bounded by a minimum value: \(\Delta x \cdot \Delta p \geq \frac{\hbar}{2}\).

To show that the uncertainty product satisfies the uncertainty principle, we need to calculate \(\Delta x\) and \(\Delta p\) for the ground state of the Harmonic Oscillator and verify that their product is greater than or equal to \(\frac{\hbar}{2}\).

If the ground state wavefunction \(\psi_0(x)\) is a Gaussian function, then the uncertainties \(\Delta x\) and \(\Delta p\) can be related to the standard deviation \(\sigma\) as follows:

\(\Delta x = \sigma\)

\(\Delta p = \frac{\hbar}{2\sigma}\)

By substituting these values into the uncertainty product inequality, we can verify that it satisfies the Heisenberg's uncertainty principle.

Regarding the statement \((x) = 0\) and \((p) = 0\) for this problem, it seems incorrect. The ground state of the Harmonic Oscillator does not have zero uncertainties in position or momentum. Both \(\Delta x\) and \(\Delta p\) will have non-zero values.

\(\frac{3}{4}p+8\geq 3\)

⇒\(\frac{3}{4}p\geq 3-8\)                              (subtracting 8 on both sides)

⇒\(3p\geq -5*4\)                             (multiplying both sides by 4)

⇒\(p\geq \frac{-20}{3}\)                                  (dividing both sides by 3)

A pyramid is a solid shape with a specified shaped base. The required answer is 8.67 cubic feet.

A pyramid is a solid shape with a specified shaped base. While a square based pyramid is a type of pyramid which has its base to be a square.

Volume of a square based pyramid = \(\frac{1}{3}\) x base area x height

Also, are of a square = length x length

So that,

i. For the first pyramid;

volume =  \(\frac{1}{3}\) x (2 x 2) x 6

            = 8 cubic feet

The volume of the first pyramid is 8 cubic feet.

ii. For the second pyramid, we have;

height = 8 feet

base side = 2.5 feet

So that.

Volume =  \(\frac{1}{3}\) x (2.5 x 2.5) x 8

             = 16.6667

Volume = 16.67 cubic meters

The volume of the second pyramid is 16.67 cubic meters.

Therefore, the volume of the second pyramid is greater than the volume of the first pyramid by;

volume of the second pyramid - volume of the first pyramid = 16.67 - 8.0

                                              = 8.67 cubic feet
