Answer: The measure of an exterior angle of a regular polygon is given by the formula:
(n-2) * 180 / n
Where n is the number of sides of the polygon.
So, if the measure of an exterior angle of a polygon is 36 degrees, we can set up the equation:
(n-2) * 180 / n = 36
To find the measure of an interior angle, we can use the formula:
(n-2) * 180 / n = (n-2) * 180 / n
So, if the measure of an exterior angle is 36, the measure of an interior angle would be:
(n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n
To find the number of sides, we can use the formula:
n = (180 / (180-x))
So, if the measure of an exterior angle is 36, the number of sides would be:
n = (180 / (180-36)) = (180 / 144) = 5
Therefore, a regular polygon with an exterior angle measure of 36 degrees has 5 sides and an interior angle measure of 144 degrees.

what is the probability that their total completion time in the maze for all rats is between 6 and 8 minutes
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.
This means that 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%.

Graph g(x)=4cosx .
Use 3.14 for π .
Use the sine tool to graph the function. Graph the function by plotting two points. The first point must be on the midline and closest to the origin. The second point must be a maximum or minimum value on the graph closest to the first point.
Answer: The graph of g(x) = 4cosx is a horizontal dilation of the graph of y = cosx by a factor of 4.
To graph the function, we can use the following two points:
(0, 4) which is the point on the midline closest to the origin
(3.14/2, 0) which is the maximum point closest to the first point
We can then use these points to plot the graph of g(x) = 4cosx using the sine tool. It will be horizontal shifted of the graph of y = cos(x) by a factor of 4.

2 red and 2 overlapping balls in the center are surrounded by a green, fuzzy, circular cloud with a white line running through it. 2 green balls sit on the white line, and a line leading a bracket around the balls is labeled A. A line leading to a bracket overlapping the white line is labeled B.Identify the parts of the atom that are labeled in the diagram.
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.

Draw the first through the fifth generations of squares, triangles and trapezoids. count how many of each shape are needed to create each generation. explain the pattern that you have observed. if a pattern does hold for each generation, how many tiles would be required at the 20th generation? how do you determine if the generation you are building is similar (by mathematical definition) to the other generations? what happens to area when you double the dimensions of a given polygon? triple them? describe the pattern and give the value needed for the 20th generation.
At the 20th generation, 400 squares, 400 triangles, and 400 trapezoids are needed.
The pattern for the first through the fifth generations of squares, triangles, and trapezoids is that each generation is made up of the previous generation's shapes, but with each shape having an additional set of smaller shapes attached to each side.
For example, in the first generation, there is only one square. In the second generation, four smaller squares are attached to the sides of the first square. In the third generation, nine smaller squares are attached to the sides of each of the four squares in the second generation, and so on.
The number of shapes needed to create each generation can be found using the formula:
(n^2)
Where n is the generation number.
For example, in the first generation, only 1 square, 1 triangle and 1 trapezoid is needed, in the second generation, 4 of each are needed, in the third generation, 9 of each are needed, and so on.
If this pattern holds for each generation, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula:
(20^2) = 400
To determine if the generation you are building is similar (by mathematical definition) to the other generations, you would need to check whether the ratio of corresponding sides is the same for each shape in the generation.
When you double the dimensions of a given polygon, the area is multiplied by four. When you triple the dimensions of a given polygon, the area is multiplied by nine.
The pattern for the number of shapes needed to create each generation follows the pattern of a square of n^2. Therefore, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula, n^2 = 20^2 = 400.

a positive integer divisor of $11!$ is chosen at random. what is the probability that this divisor is prime? express your answer as a common fraction.
The probability of a randomly chosen divisor of [tex]$11!$[/tex] being prime is [tex]$\frac{32}{3^{2}\cdot2^{10}} = \frac{1}{243}$[/tex].
COMMON FRACTION EXPRESSIONThe prime factorization of [tex]$11!$[/tex] is 11!=[tex]11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2\cdot1$[/tex], so there are [tex]$(2+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1) = (3^{2})(2^{10})$[/tex] divisors of [tex]$11!$[/tex]
The prime divisors of [tex]$11!$[/tex] are [tex]$2,3,5,7,11$[/tex], and there are [tex]$(1+1)(1+1)(1+1)(1+1)(1+1) = 2^{5} = 32$[/tex] divisors that are prime.
So the probability of a randomly chosen divisor of [tex]$11!$[/tex] being prime is [tex]$\frac{32}{3^{2}\cdot2^{10}} = \frac{1}{243}$$[/tex]
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.

a set s of distinct positive integers has the following property: for every integer x in s, the arithmetic mean of the set of values obtained by deleting x from s is an integer. given that 1 belongs to s and that 2002 is the largest element of s, what is the greatest number of elements that s can have?
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 height of a cylinder is increasing at a constant rate of 9 inches per second. the volume remains a constant 1318 cubic inches. at the instant when the radius of the cylinder is 99 inches, what is the rate of change of the radius? the volume of a cylinder can be found with the equation v
The rate of change of the radius is -9/(2π*99) inches/second.
The volume of a cylinder can be found with the equation V = πr^2h, where V is the volume, r is the radius, h is the height and π is a constant. We know that the volume is constant at 1318 cubic inches and we know that the height of the cylinder is increasing at a constant rate of 9 inches per second.
V = πr^2h
1318 = π * 99^2 * h
Now we can differentiate this equation with respect to time.
dV/dt = 2πr*dr/dt * h + πr^2 * dh/dt
where dV/dt is the rate of change of the volume, dr/dt is the rate of change of the radius and dh/dt is the rate of change of the height.
Now we know that dV/dt = 0, dh/dt = 9 and we know the value of r, we can substitute these values in the above equation and solve for dr/dt
0 = 2π * 99 * dr/dt * h + π * 99^2 * 9
dr/dt = -9/(2π*99) inches/second
The rate of change of the radius is -9/(2π*99) inches/second at the instant when the radius of the cylinder is 99 inches.
