What is square?

Having four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. Each square form may be recognised by its equal sides and 90° inner angles. A square is a closed form with four equal sides and interior angles that are both 90 degrees. Numerous different qualities can be found in a square.

On the entire sheet of paper, 243 cards were created.

The sheet is described as being 324 cm 144 cm in size.

Measures 324 centimeters in length.

The sheet has a 144-cm width.

We need to determine how many cards with a 16 cm by 12 cm size can be produced from a single sheet of paper.

The length of segment PM would be 12 units

I won't proceed based on your circle's association with any specific segments; instead, I'll use the illustration below.

We can determine QM = 15, SM = 10, and RM = 18 from the image. We apply the formula for determining segment lengths when there are two chords in a circle to determine the length of segment PM.

Our equation QM = (SM)(RM) (PM)

We now enter the information and resolve: (10)(18) = (15)(x) (x)

(10)(18) = 180

(15)(x) = 15x

180 = 15x → 180 ÷ 15 = 12 & 15x ÷ 15 = x

The amplitude of v(t) at steady-state is (a) Amplitude = KFc. This is because the amplitude of the response in a linear system is proportional to the amplitude of the forcing function, and the constant of proportionality is the system gain, K.

In this case, the forcing function has an amplitude of Fc, and the system gain is K, so the amplitude of the response at steady-state is K times Fc, or KFc. The amplitude of v(t) at steady-state can be found by considering the relationship between the system gain (K) and the forcing function f(t). Given the forcing function f(t) = Fc * sin(100t/τ), we can determine the steady-state response by taking the amplitude of the sinusoidal forcing function and multiplying it by the system gain K. Hence, the amplitude of v(t) at steady-state is: Amplitude = K * Fc Therefore, the best answer is: a. Amplitude = KFc.

To calculate the perimeter and volume of the small rectangular mirror, we'll use the given dimensions in inches and convert the final answer to centimeters.

First, let's calculate the perimeter of the front of the mirror:

Perimeter = 2 * (length + width)

Perimeter = 2 * (2.2325 in + 1.116 in)

Perimeter = 2 * 3.3485 in

Perimeter = 6.697 in

Now, let's convert the perimeter from inches to centimeters:

Perimeter_cm = Perimeter * 2.54 cm/in

Perimeter_cm = 6.697 in * 2.54 cm/in

Perimeter_cm = 17.00138 cm (rounded to 5 significant figures)

Next, let's calculate the volume of the mirror:

Volume = length * width * thickness

Volume = 2.2325 in * 1.116 in * 0.041 in

Volume = 0.10137243 in^3

Now, let's convert the volume from cubic inches to cubic centimeters:

Volume_cm = Volume * (2.54 cm/in)^3

Volume_cm = 0.10137243 in^3 * (2.54 cm/in)^3

Volume_cm = 1.66487136112 cm^3 (rounded to 6 significant figures)

Therefore, the perimeter of the front of the mirror is approximately 17.001 cm and the volume of the mirror is approximately 1.66487 cm^3.

The statement "The OLS parameter estimates minimize the Bj S" is False.Explanation:The ordinary least squares (OLS) estimator is an estimator that calculates the best linear unbiased estimates for multiple linear regression models with a single response variable and many predictor variables.

The method of least squares can be used to estimate unknown parameters in a statistical model by minimizing the differences between observed responses and those predicted by the model.The method of least squares estimates the model parameters by minimizing the sum of the squares of the residuals (the difference between the observed data values and the fitted values provided by a model) rather than the sum of the residuals. OLS regression finds the slope and intercept that minimize the sum of squared residuals, also known as the residual sum of squares (RSS).In multiple linear regression, it is common to use the residual sum of squares (RSS) as a measure of how well the model fits the data.

RSS is defined as:

$$RSS = \sum_{i=1}^n (y_i-\hat{y_i})^2$$

where $$y_i$$is the ith observed response value, $$\hat{y_i}$$is the ith predicted response value, and n is the sample size. The OLS estimates of the regression parameters that minimize the residual sum of squares (RSS) are known as the least squares estimates or OLS estimates, which is what makes this method so popular and useful in linear regression modelling.So, The OLS parameter estimates minimize the residual sum of squares (RSS). Therefore, the given statement "The OLS parameter estimates minimize the Bj S" is False.

Answer:

1.25 oz

Step-by-step explanation:

Since 1 / 0.80= 1.25

The probability that X is between 57 and 105 is 0.8914.

Given:

* X is normally distributed with mean=90 and standard deviation=12

* P(57 < X < 105)

Solution:

* Convert the given values to z-scores:

   * z = (X - μ) / σ

   * z = (57 - 90) / 12 = -2.50

   * z = (105 - 90) / 12 = 1.25

* Use the z-table to find the probability:

   * P(Z < -2.50) = 0.0062

   * P(Z < 1.25) = 0.8944

* Add the probabilities to find the total probability:

   * P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

Therefore, the probability that X is between 57 and 105 is 0.8914.

Answer:  

Slope = 2/3

y-intercept = 1

The equation in slope intercept form is y = 2/3 x + 1

OR y = 2x/3 + 1

Step-by-step explanation:

m is the slope. b is the y-intercept.

Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 2/3 and the y-intercept is +1

Step-by-step explanation: To find the slope, m, determine  "rise over run"

Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–3,–1), (0,1) and (3,3)

The "rise" is the difference in y-values. Here, they increase by 2.

The "run" is the difference in x-values. Here they increase by 3.

So the slope is 2/3. Put that in place of m in the equation

The graphed line crosses the y-axis at +1

That is the y-intercept.  Use +1 in the place of  b

Keep the y and x; substitute the values for m and b we found.

y = 2/3 x + 1

OR

y = 2/3+ 1  This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be multiplied by 2 and divided by 3.

Answer:

0, 1/18, and 1/36

Step-by-step explanation:

For i = 2, the probability it lands on 6 is 0, because you cannot sum to 2 with a 6. The same applies to i = 3 thru i = 6.

For the probability that at least one of a pair of fair dice lands on 6 for i = 7, there are only two possible ways, the first roll is a 6 and the second roll is a 7, and the first roll is a 1 and the second roll is a 6. The total amount of ways is 6 * 6 = 36, so the total probability is 1/18. This also applies to i = 8 thru i = 11.

For i = 12, there is only one way to get 12, the first dice lands on 6 and the second dice lands on 6. Assuming the dice are indistinguishable, the probability is 1/36.

The probability that at least one of a pair of fair dice lands on 6, given that the sum of the dice is i, where i ranges from 2 to 12, is 23/12.

We have,

The complementary probability of "at least one die lands on 6" is "neither of the dice lands on 6."

Therefore, you need to find the probability that neither of the dice lands on 6 for each possible sum i, and then subtract that probability from 1 to get the desired probability.

Let's go through the cases:

i = 2 (only possible sum with two dice):

In this case, both dice must show a 1.

The probability of this happening on a fair 6-sided die is

(1/6) * (1/6) = 1/36.

i = 3: The combinations are (1, 2) and (2, 1).

The probability of either happening is 2 * (1/6) * (1/6) = 1/18.

i = 4:

The combinations are (1, 3), (2, 2), and (3, 1).

The probability of any of these happening is 3 * (1/6) * (1/6) = 1/12.

i = 5:

The combinations are (1, 4), (2, 3), (3, 2), and (4, 1).

The probability of any of these happening is 4 * (1/6) * (1/6) = 1/9.

i = 6:

The combinations are (1, 5), (2, 4), (3, 3), (4, 2), and (5, 1).

The probability of any of these happening is 5 * (1/6) * (1/6) = 5/36.

i = 7:

The combinations are (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).

The probability of any of these happening is 6 * (1/6) * (1/6) = 1/6.

i = 8:

The combinations are (2, 6), (3, 5), (4, 4), (5, 3), and (6, 2).

The probability of any of these happening is 5 * (1/6) * (1/6) = 5/36.

i = 9:

The combinations are (3, 6), (4, 5), and (5, 4).

The probability of any of these happening is 3 * (1/6) * (1/6) = 1/12.

i = 10:

The combinations are (4, 6) and (6, 4).

The probability of either happening is 2 * (1/6) * (1/6) = 1/18.

i = 11:

The combinations are (5, 6) and (6, 5).

The probability of either happening is 2 * (1/6) * (1/6) = 1/18.

i = 12:

The combination is (6, 6).

The probability of this happening is (1/6) * (1/6) = 1/36.

Now, sum up the probabilities for each case:

(1/36) + (1/18) + (1/12) + (1/9) + (5/36) + (1/6) + (5/36) + (1/12) + (1/18) + (1/18) + (1/36)

This simplifies to:

69/36 = 23/12

Thus,

The probability that at least one of a pair of fair dice lands on 6, given that the sum of the dice is i, where i ranges from 2 to 12, is 23/12.

Answer:

When x = 4 and z = 3, y = 4.5.

Step-by-step explanation:

If y varies directly as x and inversely as z, then we can write the following proportion:

y/x = k/z

where k is the constant of proportionality. We can solve for k using the given values:

6/5 = k/2

k = 12/5

Now we can use this value of k to find y when x = 4 and z = 3:

y/4 = (12/5)/3

y/4 = 4/5

y = (4/5) * 4

y = 3.2

Therefore, when x = 4 and z = 3, y = 4.5.

The volume of the pyramid is approximately 5.9 cm³.

To find the volume of a pyramid with a square base, you can use the formula:

Volume = (1/3) * base area * height

First, let's find the area of the square base. The perimeter of the base is given as 5.7 cm, which means each side of the square has a length of 5.7 cm / 4 = 1.425 cm.

The area of a square is given by the formula:

Area = side length * side length

Substituting the side length, we have:

Area = 1.425 cm * 1.425 cm = 2.030625 cm²

Now, we can calculate the volume of the pyramid:

Volume = (1/3) * base area * height

= (1/3) * 2.030625 cm² * 8.6 cm

= 5.91834375 cm³

Rounding to the nearest tenth of a cubic centimeter, the volume of the pyramid is approximately 5.9 cm³.
