Answer: The domain and range is equal to all positive real numbers.

Explanation: The domain and range of the function shown is equal to all positive real numbers because there is no such a value that the function can have an indeterminate situation and also there is no such another positive value that the function cannot have as a result.

The greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

The property of the set s states that for every element x in s, the arithmetic mean of the set obtained by deleting x from s is an integer.

To understand this property, we can start by considering the case when the set s has only two elements, say x and y. In this case, the arithmetic mean of the set obtained by deleting x from s is y, and the arithmetic mean of the set obtained by deleting y from s is x. As both x and y are integers, this property holds true.

When the set s has three elements, say x, y, and z. The arithmetic mean of the set obtained by deleting x from s is (y+z)/2. as y and z are integers, (y+z) is always even, thus (y+z)/2 is always an integer. The same applies to the arithmetic mean of the set obtained by deleting y and z.

As we can see, this property holds true for any set of distinct positive integers, no matter the number of elements.

Given that 1 belongs to s and that 2002 is the largest element of s, we can use the property of the set to find the greatest number of elements that s can have.

The arithmetic mean of the set obtained by deleting 1 from s is (x+y+z+...+2002)/(n-1) = (x+y+z+...+2002)/n + 1/n. as x, y, z... 2002 are integers, (x+y+z+...+2002) is always an integer, thus (x+y+z+...+2002)/n is always an integer. Then, as 1/n is always an integer, (x+y+z+...+2002)/n + 1/n is always an integer.

Therefore, the greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

The previous balance in the account is equivalent to $68.303.

Given is that in August, Billy Quinlin deposited a total of $724 into his checking account. He wrote $585.27 in checks, had a service charge of $29.00 and earned $10.00 in interest. If his current balance is 239.46.

Assume that the initial cost was ${x}. So the total cost after depositing $724, the total amount will be ${x + 724}.

Total amount withdrawn = $585.27 + $29 = $614.27

Amount earned after interest -

10% of 614.27

(10/100) x 614.27

$61.427

Now, we can write -

{x + 724} - {614.27} + {61.427} = {239.46}

{x + 724} + {61.427} = {239.46 + 614.27}

x + 785.427 = 853.73

x = 853.73 - 785.427

x = 68.303

Therefore, the previous balance in the account is equivalent to $68.303.

The system of equations can have an infinite number of solutions when the equations are equivalent.

A system of equations can have infinitely many solutions when the equations are equivalent, meaning that the equations are identical when one is subtracted from the other. When this happens, the system of equations is said to have an infinite number of solutions. To solve a system of equations by elimination with infinitely many solutions, the equations must first be rearranged so that the same variable terms are on one side and the constant terms are on the other. Then, the coefficients of one variable must be made equal by multiplying one or both equations by a constant. After this, the equations can be added together or subtracted from one another and the variable terms will cancel out. This will result in an equation with only the constant terms, which is equivalent to 0=0. This equation is true for all values of the variables, so the system of equations has an infinite number of solutions.

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x

-4x + 1 = 6x - 9   Add 4x from both sides

-4x  + 4x + 1 = 6x + 4x -9

1 = 10x - 9  Add 9 to both sides

The required difference in time taken by bob and sam is 0.8 hour.

Speed is defined as. The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Bob can drive 50 miles in 40 minutes.

So, Speed of bob = 50×60/40 = 75 miles/hour

And Sam can drive 90 miles in 105 minutes.

Speed of Sam = 90×60/105 = 51.4 miles/hour

Now/

Time taken by bob(d) = 120/75 = 1.6

Similarly,

Time taken by Sam(e) = 120/51.4 = 2.4

So,

Answer: 45°

Step-by-step explanation:

Let the angle be x and its complement be y

Also,

Complement = 1/3 × Supplement

So,

Supplement = 3 × Complement

                     = 3y

According to Question:

I.              x + y = 90°                          -----(1)

II.             x + 3y = 180°                       -----(2)

On subtracting eq (1) from (2) we get

               2y=90°

                 y=45°

Now, From eq (1)

                x + y = 90°  

                 x = 90° - 45°

                 x = 45°

∴ The angle is 45°

They describe a model of an atom with two protons, two neutrons, electron density (orbitals), and two electrons. Now suppose we want to know what the labels A and B stand for.

The nucleus is at the center where the protons and neutrons are arranged. This is supported by his three models: the Rutherford model, the Bohr model and the (now accepted) quantum model.

So the red sphere and the two overlapping spheres in the middle represent protons and neutrons.

The line labeled A with the sphere in brackets represents the nucleus, as it signals both protons and neutrons within the nucleus.

The green blurry circular clouds represent the regions where electrons reside. This is blurry according to the quantum model, which states that the electrons are not in a fixed position, but in the region around the atom. This area is called the trajectory. According to the model, the electron's exact position cannot be determined, which means a blurry cloud.

This white line, which in Bohr's model should be circular where the electrons are, represents the electron orbits and shells identified by the letters L, M, N, and K. The first shell was the L shell.

In the quantum model, this line corresponds to the principal quantum number n (principal energy level). Therefore, the lines leading to brackets overlapping the white lines indicate the main energy levels.

Atoms are neutral because they contain as many electrons as protons around the nucleus.

A common fraction is a way of representing a ratio of two integers, where the numerator (the top part) represents the number of "favorable outcomes" and the denominator (the bottom part) represents the total number of possible outcomes.

In this case, the favorable outcome is a randomly chosen divisor of 11! being prime, and the total number of possible outcomes is the total number of divisors of 11! which is[tex]$(3^{2} )(2^{10})$[/tex]. So the probability of a randomly chosen divisor of 11! being prime can be represented as a common fraction by writing [tex]$\frac{32}{3^{2} \cdot2^{10}}$[/tex], with 32 as the numerator and [tex]$(3^{2})(2^{10})$[/tex] as the denominator.

The measure of angle ∠WDY is 89° in problem 20.

Two rays (half-lines) that share an endpoint make up an angle. The rays serve as the angle's sides, occasionally serving as the angle's legs and occasionally serving as its arms, while the latter is referred to as the vertex of the angle.

Two angles are said to be congruent by this definition if either of their vertex and side coordinates can be rigidly moved to coincide with the other. The angle may be written as AOB or BOA if O is the vertex and A and B are the points on the two sides (and this for any selection of the two points A and B.)

Given that D is the common point of line segments DW, DX and DY

m∠WDX = 2x - 5

m∠XDY = 52

m∠WDY = 5x - 16

to find m∠WDY

m∠WDY = m∠XDY + m∠WDX

5x - 16 = 52 + 2x - 5

5x - 2x = 52 - 5  + 16

3x = 63

x = 63/3

x = 21

m∠WDY = 5(21) - 16

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes is 0.375, or 37.5%.

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes can be calculated using the Binomial Distribution formula. The formula is P = (nCr) * (p^r) * (1-p)^(n-r), where n is the number of trials, r is the number of successes, and p is the probability of success.

In this case, n = 4 (4 rats), r = 2 (completion time between 6 and 8 minutes), and p = 0.5 (50% chance of success). Therefore, P = (4C2) * (0.5^2) * (1-0.5)^(4-2) = 0.375.
