The monthly rents for five apartments advertised in a newspaper were $670, $670, $790, $1550, and $810. Use the mean, median, mode, and range of the rents to answer the following question: Which measure of central tendency best described the advertised rents? Calculate the four measures of central tendency and provide two to four sentences supporting the answer. (I already calculate the four, I just need help with picking out the best one. Range: 880.

Answer:

First find what f(-4) is, it is 2. Then substitute the 2 into x for e(x). Then is becomes e(2) which equals -4. The output is the same as the input because they are inverses. When putting the output of the original equation as the input of the inversed equation, the output of the inversed equation becomes the input of the original equation.

The function e(f(-4)) = -4. This happens because when two function machines are pushed together, the output of the first machine is used as the input for the second machine.

The inverse of a function f(x) is a function e(x) such that e(f(x)) = x for all x in the domain of f(x). To find the inverse of Amanda's favorite function, f(x) = 1 + sqrt(x + 5), we need to isolate x in the expression 1 + sqrt(x + 5) and call it y:

y = 1 + sqrt(x + 5)

Squaring both sides of the equation, we get:

y^2 = 1 + 2sqrt(x + 5) + (x + 5)

y^2 - 1 = 2sqrt(x + 5) + x + 5

Expanding the square on the left side, we get:

y^2 - y - 6 = x

So the inverse function, e(x), can be defined as:

e(x) = y^2 - y - 6

Finally, to evaluate e(f(-4)), we first need to find f(-4), then use the result as an input to the inverse function e(x):

f(-4) = 1 + sqrt(-4 + 5) = 1 + sqrt(1) = 1 + 1 = 2

e(f(-4)) = e(2) = 2^2 - 2 - 6 = 4 - 8 = -4

Therefore, e(f(-4)) = -4.

This happens because when two function machines are pushed together, the output of the first machine is used as the input for the second machine.

The inverse of Amanda's favourite function takes the output of the first machine and finds the original input that would have produced the same output. In this case, the original input was -4.

The equation of the inverse of y = x + 3 is y = x - 3.

The theory used in this question is the concept of inverse relationships. In mathematics, an inverse relationship is a relationship where two variables are related in such a way that when one variable increases, the other decreases.

In this case, the relationship between x and y is represented by the equation y = x + 3.

To find the inverse of this equation, we need to switch the coordinates in each ordered pair, which is done by subtracting 3 from the output (y) for each ordered pair.

This gives us the equation y = x - 3, which is the inverse of y = x + 3.

The percentage decrease from the August price to the September price = 20%

Here, In July the price of a holiday is £500.

And in August the price increases by 25%.

Let 'p' represents the price of a holiday.

First we need to find the value of the 25 percent of £500.

25% of £500

= 500 × (25/100)

= £125

so, the value of p would be,

p = £500 + 25% of £500

p = £500 + £125

p = £625

In September the price drops to £500 again.

i.e., p = 500

So, the decrease in price is: 625 - 500 = 125

Now we find the percentage decrease from the August price to the September price.

(125/625) × 100 = 20%

Poisson's ratio v can get close to 1, but never reach it 1/2. G/B = 3(1-2v)/(2(1+v)) limits it.

The right hand side must be positive because the shear G and bulk B moduli must both be positive since else an elastic material would spontaneously deform. This results in -1 v 12.

Because of those  symbols, equality is not possible; consequently, G/B cannot be zero. The elasticity formulas are invalid because any substance with G = 0 is a fluid.

Keep in mind that v = 12 is the typical model for rubbers. Since the ratio G/B is greater than 6000 for gum rubbers, this estimate is only a rough guide. This presumption has the effect of ignoring any volumetric distortion.

An arithmetic progression (AP) is a sequence of numbers such that the difference between any two consecutive terms is always the same.

This common difference is called the common ratio of the arithmetic progression. The general form of an arithmetic progression is a, a + d, a + 2d, ..., where a is the first term and d is a common difference.

The nth term of an arithmetic progression can be found by using the formula: a_n = a + (n-1)d, where a is the first term, d is a common difference, and n is the position of the term in the progression.

If a, b, and c are in arithmetic progression, then the common difference is (b-a) = (c-b).

If d, e, and f are also in arithmetic progression, then the common difference is (e-d) = (f-e).

If a, d are the same and b, e are the same, then c = f.

so the common difference between both progressions is the same, and c = f

x = -3.84

y = -4.96

Step-by-step explanation:

-7x+3y=12

2x-8y=32

We multiply the first equation by 2 and the second equation by 7

-14x + 6y = 24

14x -56y = 224

-50y = 248

y = -4.96

Now put -4.96 in for y and solve for x

-7x+3(-4.96) = 12

-7x - 14.88 = 12

-7x = 26.88

x = -3.84

Let's check

-7(-3.84) + 3(-4.96) = 12

26.88 - 14.88 = 12

12 = 12

So, x = -3.84, and y = -4.96 is the correct answer.

The intensity in watts per meter squared of 85.0-dB sound is 0.316 watts per meter squared.

To calculate the intensity in watts per meter squared of 85.0-dB sound, we first need to convert the dB sound level to a ratio.

This is done by calculating 10 raised to the power of the dB sound level divided by 10.

Therefore, 10^(85.0/10) = 316.

Next, we need to convert the ratio to intensity in watts per meter squared. This is done by dividing the ratio by 1,000,000.

Therefore, 316 / 1,000,000 = 0.000316.

Finally, we need to convert the intensity in watts per meter squared to a more readable number. This is done by multiplying the intensity by 1,000,000.

Therefore, 0.000316 * 1,000,000 = 0.316 watts per meter squared.

We must first translate the dB sound level into a ratio in order to determine the intensity of 85.0-dB sound in watts per square meter.

To do this, divide the decibel sound level by 10 and multiply the result by 10 raised to that power.

Consequently, 10 (10/85.0) = 316.

The ratio must then be changed to intensity in watts per square meter. To do this, double the ratio by 1,000,000.

316 divided by 1,000,000 equals 0.000316.

Finally, we must translate the intensity measured in watts per square meter into a more understandable value. The intensity is multiplied by 1,000,000 to achieve this.
