The range of data set 1 is 20 and the range of data set 2 is 25.

From the given figure, the observations in data set 1 are 20, 25, 25, 25, 30, 30, 30, 35, 35 and 40.

The observations in data set 2 are 35, 40, 40, 45, 45, 45, 50, 50, 55 and 60.

In statistics, the range of a set of data is the difference between the largest and smallest values, the result of subtracting the sample maximum and minimum. It is expressed in the same units as the data.

From data set 1:

Highest observation = 40 and lowest observation = 20.

So, range = 40-20=20

From data set 2:

Highest observation = 60 and lowest observation = 35.

So, range = 60-35=25

Therefore, the range of data set 1 is 20 and the range of data set 2 is 25.

The first derivatives for the given functions are:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For  \(y = 100200x + 7x,\) the first derivative is dy/dx = 100207.

For \(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

To find the first derivative for each of the given functions, we'll use the power rule, constant rule, and chain rule as needed.

For the function\(y = 3x^2 + 5x + 10:\)

Taking the derivative term by term:

\(d/dx (3x^2) = 6x\)

d/dx (5x) = 5

d/dx (10) = 0

Therefore, the first derivative is:

dy/dx = 6x + 5

For the function y = 100200x + 7x:

Taking the derivative term by term:

d/dx (100200x) = 100200

d/dx (7x) = 7

Therefore, the first derivative is:

dy/dx = 100200 + 7 = 100207

For the function \(y = ln(9x^4):\)

Using the chain rule, the derivative of ln(u) is du/dx divided by u:

dy/dx = (1/u) \(\times\) du/dx

Let's differentiate the function using the chain rule:

\(u = 9x^4\)

\(du/dx = d/dx (9x^4) = 36x^3\)

Now, substitute the values back into the derivative formula:

\(dy/dx = (1/u) \times du/dx = (1/(9x^4)) \times (36x^3) = 36x^3 / (9x^4) = 4/x\)

Therefore, the first derivative is:

dy/dx = 4/x

To summarize:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For y = 100200x + 7x, the first derivative is dy/dx = 100207.

For\(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

The cylinder x = (1/z)^z has a unique shape defined by its generator curve, a directrix line at x = 1, and rulings connecting the generator curve to the directrix.

The cylinder x = (1/z)^z represents a cylindrical surface in three-dimensional space. The generator of the cylinder is obtained by fixing the x-coordinate and allowing z to vary. By doing so, we generate a curve that lies on the surface of the cylinder. This curve is known as the generator.

The directrix of the cylinder is the line x = 1. It acts as a reference line parallel to the z-axis and helps determine the position of the ruling lines. The rulings of the cylinder are straight lines that connect corresponding points on the generator curve to the directrix. These lines create a grid-like pattern that extends across the surface of the cylinder.

The statement that describes the slope how it relates to the height of the water in the pool is, A. The height of the water increases 2 inches per minute.

The slope can also be referred too as a unit rate or constant rate of change. It is calculated as:

Slope (m) = change in y / change in x.

Given the table, where:

x = time in minutes

y = height of water

Using two points, (2, 8) and (4, 12) from the table:

Slope (m) = the height of water per minute = change in y / change in x = (12 - 8) / (4 - 2)

  \   /    

   B    

  /   \

 F     B     F

In this molecule, there are three atoms (one boron and two fluorine) and a total of 12 valence electrons. Boron is in group 3, so it has 3 valence electrons, while each fluorine atom has 7 valence electrons.

To form the Lewis dot structure, we first place the atoms in a linear arrangement. Each fluorine atom shares one electron with the boron atom, giving a total of two shared electrons (or one bond) between the boron and each fluorine atom. This gives us a total of four electrons (or two bonds) between the boron and the two fluorine atoms.

The remaining four electrons are placed as nonbonding electron pairs around each fluorine atom to satisfy the octet rule. Therefore, there are a total of two bonding domains and two nonbonding electron domains around the boron atom. The electron domain geometry is tetrahedral, and the molecular geometry is linear.

Step-by-step explanation:

The given sequence is arithmetic (linear). Recursive expression:** tn = tn-1 - 15

In an arithmetic sequence, each term is obtained by adding or subtracting a constant value, called the common difference, to the previous term. In this case, each term is obtained by subtracting 15 from the previous term. Therefore, the recursive expression to represent the sequence is tn = tn-1 - 15.

The recursive expression tn = tn-1 - 15 indicates that to find the nth term (tn) of the sequence, we subtract 15 from the (n-1)th term (tn-1). This pattern continues throughout the sequence, with each term decreasing by 15 compared to the previous term.

Answer:

(x + 1)(x + 2) is divisible by 3.

Step-by-step explanation:

Assume that x is not divisible by 3. This means that x can be expressed as x = 3k + r, where k is an integer and r is the remainder when x is divided by 3. Since x is not divisible by 3, the remainder r must be either 1 or 2.

Case 1: r = 1

If r = 1, then x = 3k + 1. Now let's consider (x + 1)(x + 2):

(x + 1)(x + 2) = (3k + 1 + 1)(3k + 1 + 2)

= (3k + 2)(3k + 3)

= 3(3k^2 + 5k + 2)

We can see that (x + 1)(x + 2) is divisible by 3.

Case 2: r = 2

If r = 2, then x = 3k + 2. Now let's consider (x + 1)(x + 2):

(x + 1)(x + 2) = (3k + 2 + 1)(3k + 2 + 2)

= (3k + 3)(3k + 4)

= 3(3k^2 + 7k + 4)

We can see that (x + 1)(x + 2) is divisible by 3.

The domain is (-∞, ∞) and the range of the function is (3, ∞). The minimum value of the given function is the lowest point at (2, 3) the maximum value cannot be determined as the function is extending.

The collection of all potential input values—also referred to as the independent variable—for which a function can be defined is known as the domain of the function. In order for the function to provide a useful output, a set of all possible values of x must be passed into it.

The collection of all potential output values (sometimes referred to as the dependent variable) that a function can generate for the input values falling within its domain is known as the function's range. In other words, it is the collection of all possible values of y that result from the function when x values from the domain are plugged in.

The domain of the function is all the input values or the x-coordinates of the graph.

Here, the x-coordinates of the graph are from all the real numbers as the function extents to infinity on both sides.

The range of the function is all the output values or the y-coordinate of the graph.

In the given graph the y-coordinates are 3 to infinity as the graph extends.

Hence, the domain is (-∞, ∞) and the range of the function is (3, ∞)

Step-by-step explanation:

Note:
The formula to find probability is:

P(A) = n(A) / n(S)

where:

For question:

a.

There are 13 hearts in a standard deck of 52 cards, so the probability of drawing a heart is 13/52.

The probability that the first card drawn is a heart is 13/52 = 1/4.

b.

Since the first card was not a heart, there are 13 hearts left in the deck. There are also 51 cards left in the deck overall, so the probability of drawing a heart is 13/51.

The probability that the second card drawn is a heart given that the first card drawn was not a heart is 13/51.

c.

Since the first card was a heart, there are 12 hearts left in the deck. There are also 51 cards left in the deck overall, so the probability of drawing a heart is 12/51.

The probability that the second card drawn is a heart given that the first card drawn was a heart is 12/51.

The appropriate domain of the function, using h to represent time, is [0, ∞) or h ≥ 0, since Jevonne's distance from home can never be negative.

Since Jevonne's distance from home can never be negative, the domain of the function is restricted to non-negative values of h. Therefore, an appropriate domain of the function, using h to represent time, is:

h ≥ 0

Inequality notation can be used to express this domain as:

[0, ∞)

This means that h can take any non-negative value, including zero (which corresponds to the starting point of Jevonne's journey), and can increase without bound as Jevonne continues to drive further away from home.

The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

Step-by-step explanation:

The area (A) of each pizza is given by:

\( A = \pi r^{2} \)

Where:

r: is the radius

For the 12-inch pizza we have:

\( A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch \)

And for the 6-inch pizza we have:

\( A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch \)

The ratio between A₆ and A₁₂ is:

\( \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} \)

Hence:

\( A_{6} = \frac{A_{12}}{4} \)

Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

I hope it helps you!

To determine the percentage of Ralph's total annual income withheld for taxes, we need to calculate the total amount withheld for taxes and then divide it by his total annual income.

The total amount withheld for taxes is the sum of federal taxes and state taxes: Total taxes withheld = Federal taxes + State taxes, Total taxes withheld = $18,380 + $3,448, Total taxes withheld = $21,828. To calculate the percentage, we divide the total taxes withheld by Ralph's total annual income and multiply by 100: Percentage of taxes withheld = (Total taxes withheld / Total annual income) * 100.  Percentage of taxes withheld = ($21,828 / Total annual income) * 100.

Step-by-step explanation:

The population 4 years later is approximately 6,000. To find the population 4 years later, we need to integrate the rate of growth equation dN/dt = 500 + 600√t with respect to t.

The population of the new city 4 years after its incorporation can be found by integrating the rate of the growth equation dN/dt = 500 + 600√t with the initial condition N(0) = 3,000.

This will give us the function N(t) that represents the population at any given time t.

Integrating the equation, we have:

∫dN = ∫(500 + 600√t) dt

N = 500t + 400√t + C

To find the value of the constant C, we use the initial condition N(0) = 3,000. Substituting t = 0 and N = 3,000 into the equation, we can solve for C:

3,000 = 0 + 0 + C

C = 3,000

Now we can write the equation for N(t):

N(t) = 500t + 400√t + 3,000

To find the population 4 years later, we substitute t = 4 into the equation:

N(4) = 500(4) + 400√(4) + 3,000

N(4) = 2,000 + 800 + 3,000

N(4) ≈ 6,000

Therefore, the population of the new city 4 years after its incorporation is approximately 6,000.
