True. Even though the sample is random, it is not representative of the population of interest.

A representative sample is a subset of a population that accurately reflects the total population in terms of the characteristics being measured. In this case, 500 surveys were sent to randomly selected participants in the public recreation program, and only 150 responses were received. This results in a response rate of 30%. The formula for calculating the response rate is (responses/population x 100). By having a low response rate, the sample size is not large enough to accurately reflect the characteristics of the population of interest.

The triangle JLK is transformed to J''K''L'' by a rotation of 90° anticlockwise and a translation of -2 units

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the triangle be represented as ΔJKL

Now , the coordinates of the triangle JKL is

J ( 2 , -4 ) , K ( 5 , -4 ) and L ( 2 , -2 )

And , the transformed triangle be represented as Δ J''K''L

Now , the coordinates of the triangle J''K''L'' is

J'' ( 2 , 2 ) , K'' ( 2 , 5 ) and L'' ( 0 , 2 )

The triangle JKL is first rotated by an angle of 90° counterclockwise rotation: (x,y) becomes (-y,x) to form J'K'L'

So , substituting the values in the equation , we get

The coordinates of the triangle J'K'L' is

J' ( 4 , 2 ) , K' ( 4 , 5 ) and L' ( 2 , 2 )

Now , when the triangle is translated -2 units to up , we get

So , the coordinates of the triangle J''K''L'' is

J'' ( 2 , 2 ) , K'' ( 2 , 5 ) and L'' ( 0 , 2 )

Hence , the transformed triangle is going through a rotation of 90° counterclockwise and a translation of -2 units

The Methods used that summarize or organize characteristics of data is descriptive.

Methods used to summarize or organize characteristics of data are referred to as descriptive methods.

Descriptive methods are used to describe the basic features of a set of data, such as its central tendency (mean, median, mode) and dispersion (range, variance, standard deviation). These methods provide a summary of the data, often through the use of graphical representations such as histograms, bar charts, and scatter plots.

The goal of descriptive methods is to understand the underlying structure of the data, identify patterns, and present the data in a clear and meaningful way.

Descriptive methods do not make inferences about a population based on a sample or draw conclusions about causality.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s. If both these ratios are proportional, then we can write it as p : q = r : s or p/q = r/s

Given that,

Time taken to travel 105 km = 1 hr 45 min = 60 min + 45 min = 105 minutes

Time taken to travel 18 km = x

Using the concept of proportion,

Suppose the detector will sound the alarm if more than 2 milligrams of the dye are in your system. It will take 56 minutes for the visit of the doctor

The amount of radioactive dye remaining in your system after t minutes can be modeled as:

A(t) = 11 * (1/2)^(t/20)

where A(t) is the amount of dye remaining after t minutes. We want to find the time t when A(t) = 2 milligrams.

A(t) = 11 * (1/2)^(t/20) = 2

Solving for t:

(1/2)^(t/20) = 2/11

Taking the natural logarithm of both sides:

(t/20) = ln(2/11) / ln(1/2)

Multiplying both sides by 20:

t = 20 * ln(2/11) / ln(1/2)

b. The percentile rank for a fare of $227 is 91.11%.

c. Based on your first two answers, for $173 train fare would have a percentile rank of approximately 82%.

a. We have to determine the percentile rank for a fare of $119.

Total number of fare below and at the fare $119 = 27

Total fare = 90

The percentile rank for a fare of $119 = Total number of fare below and at the fare $119/Total fare × 100

The percentile rank for a fare of $119 = 27/90 × 100

The percentile rank for a fare of $119 = 0.3 × 100

The percentile rank for a fare of $119 = 30%

b. We have to determine the percentile rank for a fare of $272.

Total number of fare below and at the fare $272= 82

Total fare = 90

The percentile rank for a fare of $272 = Total number of fare below and at the fare $272/Total fare × 100

The percentile rank for a fare of $272 = 82/90 × 100

The percentile rank for a fare of $272 = 0.911 × 100

The percentile rank for a fare of $272 = 91.11%

c. Based on your first two answers, We have to determine which train fare would have a percentile rank of approximately 82%.

The percentile rank for a fare of $119 is 30%.

The percentile rank for a fare of $272 is 91.11.

There are three pricing ranging from $119 to $272. The percentile rank of 82% for the $272 response to section B is closer to 91.11%. $173 is the cost next to $272. Therefore, it makes the most sense that $173 would have a percentile rank of about 82%. Determine how many fares there are

Answer:

[tex]f^{-1}(x)=\sqrt[4]{x}+2 \qquad \textsf{for $x \geq 0$}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=(x-2)^4[/tex]

The domain of the given function is restricted:  

Therefore, the range of the given function is also restricted:  

To find the inverse of a function, swap x and y:

[tex]\implies x=(y-2)^4[/tex]

Rearrange the equation to make y the subject:

[tex]\implies \sqrt[4]{x}=y-2[/tex]

[tex]\implies y=\sqrt[4]{x}+2[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=\sqrt[4]{x}+2[/tex]

The domain of the inverse of a function is the same as the range of the original function.  Therefore, the domain of the inverse function is restricted to {x : x ≥ 0}.

Therefore, the inverse of the given function is:

[tex]f^{-1}(x)=\sqrt[4]{x}+2 \qquad \textsf{for $x \geq 0$}[/tex]

The positive integer representing possible values for third side length of the triangle as per given measure of two side length are 45.

Two side length of a triangle be 'x' and 'y'

Side length 'x' = 23

Side length 'y' = 53

Third side length be 'n'

Using triangle inequality we have ,

x + y > n

⇒ 23 + 53 > n

⇒ 76 > n ___(1)

And x + n > y

⇒ 23 + n > 53

⇒ n > 53 - 23

⇒ n > 30 ___(2)

We know 'n' is a positive integer .

30 < n < 76

All the positive integer between 30 and 76 are possible values for 'n'.

where a is the lower boundary of the range of assembly time (6 minutes) and b is the upper boundary of the range of assembly time (10 minutes).

Substituting a = 6 and b = 10 into the formula yields:

Kristin bought 4 fancy shirts and 3 plain shirts.

Let's assume Kristin bought "x" fancy shirts and "y" plain shirts.

We know that:

x + y = 7 (the total number of shirts Kristin bought)

28x + 15y = 131 (the total amount of money she spent)

We can use the first equation to solve for one of the variables in terms of the other.

For example: y = 7 - x

Substituting this into the second equation:

28x + 15(7 - x) = 131

28x + 105 - 15x = 131

13x = -74

x = -5.692307692 (approximately)

Since x must be a positive integer (the number of fancy shirts cannot be negative or a fraction), this solution is not valid.

However, we can see that the equation does have a solution by trying a larger value for x:

x = 1

y = 6

This gives us:

28 * 1 + 15 * 6 = 131

28 + 90 = 131

118 = 131

This solution is not valid either, since the total amount spent cannot be less than the cost of the shirts.

By repeating this process, we can find that the solution is x = 4 and y = 3.
