Gauss-Jordan elimination is a method used to solve a system of linear equations by reducing the augmented matrix of the system to a reduced row-echelon form through a series of elementary row operations.

The process involves manipulating the rows of the augmented matrix to obtain a triangular matrix, where all entries below the diagonal are zero. This is achieved by applying elementary row operations such as adding a multiple of one row to another row or multiplying a row by a scalar.

Once the augmented matrix is in triangular form, further elementary row operations are used to eliminate the nonzero entries above the diagonal. This results in the augmented matrix being in reduced row-echelon form, where the pivot elements are all equal to 1 and the columns corresponding to the pivot elements are linearly independent.

Answer:

y^2 - 5y = 750

Step-by-step explanation:

If length = y

then width = y - 5

Area = length x width

= y(y-5) = 750

Or, y^2 - 5y = 750

This equation can be further solved as follows:

y^2 - 5y - 750 = 0

Or, y^2 - 30y + 25y - 750 = 0

Or, y(y - 30) + 25(y - 30) = 0

Or, (y + 25)(y-30) = 0

So, there are two possibilities:

If (y + 25) = 0

then y = -25

but value of length cannot be negative,

Let us look at second possibility

If (y - 30) = 0

then y = 30

So, length = 30 feet

Check Answer:

Length = 30 feet

so, width = 30 - 5 = 25 feet

so, area  = 30 x 25 = 750 square feet

The coefficient of variation (CV) calculator is a tool that helps you calculate the relative variability of a dataset. The coefficient of variation is the ratio of the standard deviation (SD) to the mean (μ) expressed as a percentage, and it is used to compare the variability of datasets with different units or scales.

The formula for the coefficient of variation is:

CV = (SD / μ) x 100%

To use a coefficient of variation calculator, you need to input the values of the dataset, either one by one or as a list, and select the type of data you have (sample or population). The calculator will then calculate the mean, standard deviation, and coefficient of variation of the dataset.

The coefficient of variation is commonly used in quality control, finance, and other fields to compare the variability of different datasets. A high coefficient of variation indicates that the dataset has a large amount of variability relative to the mean, while a low coefficient of variation indicates that the dataset has a small amount of variability relative to the mean.

The coefficient of variation is only meaningful when the mean is non-zero. If the mean is zero or close to zero, the coefficient of variation can be infinite or undefined.

Answer: 20

Step-by-step explanation: The volume formula for a rectangular pyramid is [tex]\frac{lwh}{3}[/tex] so the initial volume would be 540. Since you are dilating it by 1/3 the length, with, and height are all shrinking by 1/3. 1/3*1/3*1/3 is 1/27 so that means the final thing will be 1/27 of its original size.

Answer:

So, first let's understand what a scale factor is. A scale factor is a number that tells you how much you need to multiply the size of an object to make it bigger or smaller. In this case, the scale factor is 1/3, which means we're going to make the pyramid one third of its original size.

Now, let's talk about how we can find the volume of the pyramid. The formula for the volume of a pyramid is:

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

The base area is the area of the rectangle at the bottom of the pyramid, which we can find by multiplying the length and width:

Base area = 9 cm x 12 cm = 108 square cm

The height of the pyramid is given as 15 cm, so we can substitute these values into the formula:

Volume = (1/3) x 108 square cm x 15 cm

Volume = 540 cubic cm

So the volume of the original pyramid is 540 cubic cm. But we need to find the volume of the pyramid after it is dilated by a scale factor of 1/3. To do this, we need to multiply the original volume by the scale factor cubed. The reason we cube the scale factor is because we're scaling in three dimensions (length, width, and height).

Scale factor cubed = (1/3) x (1/3) x (1/3) = 1/27

Volume of dilated pyramid = 540 cubic cm x 1/27

Volume of dilated pyramid = 20 cubic cm (rounded to the nearest whole number)

So the volume of the pyramid after it is dilated by a scale factor of 1/3 is 20 cubic cm.

The conversion of 2.5 inches to mm is 63.5 mm.

Millimeter (mm) and inch (in) are both units of length used to measure distance, length or height.

The millimeter is a metric unit of length, commonly used in most countries around the world. One millimeter is equal to one thousandth (1/1000) of a meter. Millimeters are often used in fields such as engineering, architecture, and manufacturing.

To convert 2.5 inches to millimeters (mm), you can use the conversion factor of 25.4 mm per inch.

So, the calculation is:

2.5 inches x 25.4 mm/inch = 63.5 mm

Therefore, 2.5 inches is equal to 63.5 mm.

A differential equation is an equation including dependent variables and their derivatives concerning independent variables.

Given the equation is y" - 6y' + 8y = 0. This can be written as [tex]\frac{d^2y}{dx^2}-6\frac{dy}{dx}+8y=0[/tex].

Now, let's substitute d/dx = m, and we get,

Then, the general solution will be written as [tex]y(x)=C_1e^{2x}+C_2e^{4x}[/tex]. Then, [tex]y_1=C_1e^{2x}[/tex] and [tex]y_2=C_2e^{4x}[/tex]. Hence, the solution of a given ODE is always this y₁ or y₂ or the combination of these. Therefore, (I) cannot be possible.

Answer:

Step 1: Given AD || BC and AB || CD.

Step 2: Angle A and Angle C are alternate interior angles, so they are congruent.

Step 3: Angle B and Angle D are alternate interior angles, so they are congruent.

Step 4: Angle B + Angle D = 180 degrees (because Angle A + Angle B + Angle C + Angle D = 360 degrees for a quadrilateral)

Step 5: Since Angle B and Angle D are congruent and their sum is 180 degrees, they must each be 90 degrees.

Step 6: Triangle ABZ and Triangle CDZ are both right triangles, since Angle B and Angle D are each 90 degrees.

Step 7: By the Angle-Angle Similarity Theorem, triangles ABZ and CDZ are similar.

Step 8: Since triangles ABZ and CDZ are similar, corresponding sides are proportional.

Step 9: Therefore, ZB/ZD = AB/CD, since ZB corresponds to AB and ZD corresponds to CD.

Step 10: Given that AB || CD, we know that AB/CD = AZ/CZ (the corresponding sides of similar triangles are proportional).

Step 11: Therefore, ZB/ZD = AB/CD = AZ/CZ.

Step 12: Since Angle A and Angle C are congruent (Step 2), we know that AZ = CZ (since they are opposite sides of an isosceles triangle).

Step 13: Therefore, ZB/ZD = AZ/CZ = 1, which means that ZB = ZD.

Thus, we have proved that ZB = ZD!

In general, if the sample size is large, adding an extremely large outlier to a data set will not substantially affect sample mean. The correct option is (b) sample mean

The sample size is large, adding an extremely large outlier to a data set will not substantially affect the sample mean.

This is because the sample mean is a measure of central tendency that is influenced by all the values in the dataset, but it is more affected by the values that are closer to it in magnitude. When the sample size is large, the impact of any individual outlier on the overall mean is typically reduced, as the outlier will be more likely to be balanced out by the other values in the dataset.

However, the addition of an extremely large outlier may still have an impact on the sample standard deviation and median, depending on the magnitude and distribution of the other values in the dataset.
