The set X/Y is the same as saying the set of all elements that are in X but not in Y and the answer is {3, 12}.

A set is a collection of distinct objects, called elements and are usually enclosed within braces { }.

An example of a set is the set of even numbers between 1 and 10 which can be written as {2, 4, 6, 8, 10}.

Types of set

Finite and Infinite Sets: A finite set is a set that has a specific number of elements, whereas an infinite set has an unlimited number of elements.

Empty Set: The empty set, denoted by ∅ or {} is a set that has no elements.

Singleton Set: A singleton set is a set that contains only one element. For example, {5} is a singleton set.

Subset: A subset is a set whose elements are all members of another set. For example, {1, 2} is a subset of {1, 2, 3, 4}.

Universal Set: The universal set is the set of all elements under consideration. It is usually denoted by U.

Disjoint Set: Two sets are disjoint if they have no common elements. For example, {1, 2} and {3, 4} are disjoint sets.

Equal Set: Two sets are equal if they have exactly the same elements.

The volume of the pyramid is 936 mi³

A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.

The volume of a pyramid is expressed as;

V = 1/3bh

where b is the base area and h is the height of the pyramid.

Area of the hexagon = 1/2 × p × a

perimeter = 6 × 6 = 36 mi

area = 1/2 × p × a

= 1/2 × 36 × 5.2

The cord will begin to stretch after approximately 1.46 seconds.

h(t) = -16t^2 + V0t + h0

149 = h0 - h(t)

Substituting h0 = 241 and h(t) = -16t^2 + V0t into this equation, we get:

149 = 241 - (-16t^2 + V0t)

The length of the hypotenuse is 7m.

Let the side opposite to 30° be the shortest leg.

The side opposite to 60° is the longest leg.

So, the side opposite to 90° is hypotenuse.

Length of the shortest side is x.

Length of longest side is [tex]\sqrt{3}x[/tex]

Length of the hypotenuse is 2x.

We know x = 7

Step-by-step explanation:

To find the greatest common factor (GCF) of three numbers, you can use the prime factorization method:

1. Find the prime factorization of each number:

- 152 = 2^3 * 19

- 171 = 3 * 3 * 19

- 57 = 3 * 19

2. Identify the common prime factors: 19 is the only common prime factor.

3. Multiply the common prime factors together: 19.

Therefore, the greatest common factor of 152, 171 and 57 is 19.

Three ordered pairs that could represent the location of another vertex of the square are (7, 2), (-5, 2), (1, 8).

To find the possible locations of the other vertices of the square, we need to determine the distance from point K to any other vertex of the square. Since the perimeter of the square is 20 units, each side of the square has a length of 20/4 = 5 units.

One way to find the other vertices is to draw a circle with center at K and radius 5 units, and then look for points on the circle that have integer coordinates. Alternatively, we can use the distance formula to calculate the distance from K to another point (x, y), which must be 5 units, and then solve for y in terms of x.

Using the distance formula, we get:

[tex]\sqrt{(x-1)^{2} +(y-1)^{2} }[/tex] = 5

Simplifying and squaring both sides, we get:

(x-1)^2 + (y-2)^2 = 25

Expanding the left side and simplifying, we get:

[tex]x^{2}[/tex] - 2x + [tex]y^{2}[/tex] - 4y + 20 = 0

Completing the square for x and y, we get:

[tex](x-1)^{2}[/tex]  + [tex](y-1)^{2}[/tex]  = [tex]6^{2}[/tex]

This is the equation of a circle with center at (1, 2) and radius 6 units. Any point on this circle that has integer coordinates could be a vertex of the square, since it will be exactly 5 units away from K.

Using this method, we can find several possible locations of the other vertices of the square. Three of them are:

The required posterior mean prevalence is closest to 0.47.

We can use Bayes' theorem to find the posterior distribution of the prevalence parameter, given the data and the Beta prior:

posterior ∝ likelihood x prior

where the likelihood is given by the binomial distribution:

likelihood = P(observing 4 cases out of 10 | prevalence)

and the prior is a Beta distribution with parameters α = β = 10:

prior = Beta(α=10, β=10)

We can calculate the posterior distribution by multiplying the likelihood and prior, and then normalizing:

posterior = Beta(α=14, β=16)

where the posterior Beta distribution has parameters α=14 (10 + 4) and β=16 (10 + 10 - 4).

The posterior mean of a Beta distribution with parameters α and β is:

posterior mean = α / (α + β)

Plugging in the values of α and β from the posterior distribution, we get:

Let x be the length of the shortest side. Then, the length of the second side is 2x, and the length of the third side is x + y, where y is the additional length.

The perimeter of the triangle is the sum of the three sides, so we have:

x + 2x + (x + y) = 60

Simplifying this equation, we get:

4x + y = 60

We also know that the area of a triangle is given by:

A = (1/2)bh

where b is the length of the base, and h is the height. Since the base of the flower bed is the shortest side of length x, we can choose the height to be y. Therefore, we have:

A = (1/2)xy

Now we need to solve for x and y. We can use the equation for the perimeter to solve for y:

y = 60 - 4x

Substituting this into the equation for the area, we have:

A = (1/2)x(60 - 4x)

Simplifying and expanding, we get:

A = 30x - 2x^2

To maximize the area, we can take the derivative of A with respect to x and set it equal to 0:

dA/dx = 30 - 4x = 0

Solving for x, we get:

x = 7.5

Substituting this back into the equation for y, we get:

y = 60 - 4x = 45

Therefore, the dimensions of the flower bed are:

shortest side = x = 7.5 feet second side = 2x = 15 feet third side = x + y = 52.5 feet

The sum of the interior angles of a 10-sided polygon is 1,440 degrees.

To find the sum of the interior angles of any polygon, you can use the formula:

sum of interior angles = (n - 2) x 180 degrees

where n is the number of sides of the polygon.

So, for a 10-sided polygon, we have:

sum of interior angles = (10 - 2) x 180 degrees

sum of interior angles = 8 x 180 degrees

sum of interior angles = 1,440 degrees

The exponential function for the given data is  y = 1.806(1.107)ˣ ,

Interpretation about parameters are,

a represents  initial population and b increase in growth by 10.7%.

Population size during 35th year is 63.

The exponential function that best represents the population growth of the species of crocodiles.

Values for parameters a and b in equation y = abˣ that best fit given data.

Using the data in the table, set up a system of equations as follows,

2 = ab¹

5 = ab¹⁰

12 = ab²⁰

22 = ab³⁰

25 = ab⁴⁰

To solve for a and b, we can divide the equations to eliminate a.

5/2 = (ab¹⁰)/(ab¹)

⇒5/2 = b⁹

12/5 = (ab²⁰)/(ab¹⁰)

⇒ 12/5= b¹⁰

22/12 = (ab³⁰)/(ab²⁰)

⇒ 22/12= b³/²

25/22 = (ab⁴⁰)/(ab³⁰)

⇒25/22 = b⁴/³

Taking the ninth root of the first equation,

The tenth root of the second

b = 1.107

a = 1.806

Exponential function that best represents the population growth of species of crocodiles is y = 1.806(1.107)ˣ

Interpreting the parameters of the model in the context of the problem.

a represents the initial population when x = 0 which is not given in the table.

And b represents the growth factor or rate of increase.

The growth factor is approximately 1.107, meaning that the population is increasing by about 10.7% each year.

To predict the population size during their 35th year, we simply plug x = 35 into the equation.

y = 1.806(1.107)³⁵

  = 63.4

  = 63(whole number)

Predict that population size of species of crocodiles during their 35th year will be approximately 63 individuals.

Therefore, the exponential function is  y = 1.806(1.107)ˣ ,

Interpretation of parameters are a is the initial population and b represents the growth increased by 10.7%.

During 35th year population is 63.

We can use the information provided to estimate the number of ducks that have red marks on the bottom.

If only 3 out of 50 people have won a small prize, then we can estimate that the probability of winning a small prize is 3/50 or 0.06. Since the person wins a small prize if there’s a red mark on the bottom of the duck, we can estimate that the proportion of ducks with red marks is also 0.06.

So, we can estimate the number of ducks with red marks as follows:

Number of ducks with red marks = 0.06 x 160

Number of ducks with red marks = 9.6

We can estimate that there are about 9 or 10 ducks with red marks on the bottom.
