Let random variable S represent the age of the attendees at a local concert. The following histogram shows the probability distribution of the random variable S.
Alfonso claims that the distribution of S is symmetric with a mean age of 36. Does the histogram support Alfonso's claim?

The image of the transformation is R' (-12, 3), S' (-12, 12) and T' (-6, 3)

The complete question is added as an attachment

The coordinates of the triangle are given as

R = (-4, 1)

S = (-4, 4)

T = (-2, 1)

The transformation is given as

Dilation by a scale factor of 3

Centered at the origin

The rule of the transformations is

(x, y) = 3(x, y)

So, we have

R' = 3 * (-4, 1) = (-12, 3)

S' = 3 * (-4, 4) = (-12, 12)

T' = 3 * (-2, 1)= (-6, 3)

Hence, the image of the transformation is R' (-12, 3), S' (-12, 12) and T' (-6, 3)

There are an infinite number of planes that are orthogonal to a given plane in space, and this is due to the fact that a plane can be thought of as a flat surface that extends indefinitely in all directions.

Orthogonal Planes in Space: In three-dimensional space, a plane is said to be orthogonal to another plane if the two planes are perpendicular to each other, i.e., their normal vectors are perpendicular. Since the normal vectors of two orthogonal planes are perpendicular to each other, this means that the angle between them is equal to 90 degrees.

Maria spent $100 in total. She spent $60 at the supermarket and $40 at the hair salon.

This problem involves calculations with fractions. Maria had $160. She spent 3/8 of it at the supermarket and 1/4 of it at the hair salon. To find out much money she spent, add the fractions and then multiply the result by the total amount of money she had.

To find how much Maria spent at the supermarket, multiply $160 by 3/8: 160 * 3/8 = $60.

To find how much Maria spent at the hair salon, multiply $160 by 1/4: 160 * 1/4 = $40.

Now, add the amounts spent at the supermarket and the hair salon: $60 + $40 = $100. So Maria spent $100 in total.

The equation that represent the value of the computer in years is: computer cost at (n-1) year - 1/5 (n-1cost) and the computer be worth less than $100 at 10 year

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

According to the data problem,

The cost of computer = $ 800

It lost 1/5 of value every year.

The value of computer after 0 years = cost of computer = $ 800

The value after 1 year = 800 - (1/5*800) = $640

The value after 2 years = 640 - (1/5*640) = $512

The value after 3 years = 512- (1/5*512) = $409.6

Continue with the formula we have:

The value after 9 years = 134.21 - (1/5*134.21) = 107.37

The value after 10 years = 107.37 - (1/5*107.37) = 85.90

Answer: 90 degrees.

Step-by-step explanation:

Step 1: The smallest angle must be 90/2 = 45 degrees.

Step 2: The largest angle is twice the size of the smallest angle, so it is 90 degrees.

The solution to the division problem is xyz = −434 with a remainder of 0.

The given equation is [tex]$\frac{4-4-40-1-100-1}{xyz} = -434$[/tex]. To solve this equation, we need to find the value of [tex]$xyz$[/tex]. We can use the distributive property to break up the numerator, yielding [tex]$\frac{(-1)(-100)(-1)}{xyz} = -434$[/tex]. Then, we can multiply both sides by [tex]$xyz$[/tex] to get [tex]$(-1)(-100)(-1)xyz = -434xyz$[/tex] . Since the terms on both sides of the equation are equal, we can simplify to [tex]$(-1)(-1)(-100)xyz = -434xyz$[/tex] . Now, we can factor out the xyz, which yields  [tex]$xyz(-1)(-1)(-100) = -434xyz$[/tex]. Since we want to find the value of xyz, we can divide both sides by the common factor of xyz, yielding [tex]$(-1)(-1)(-100) = -434$[/tex] . Finally, we can solve for xyz by multiplying both sides by the common factor of (-1)(-1)(-100), yielding xyz = -434. Therefore, the value of xyz in the given equation is -434.

In nature, there are various constraints on population number and expansion. Some are depending on the density, whereas others are not.

A population's per capita growth rate changes—typically declines—with rising population density due to density-dependent limiting constraints. One illustration is how individuals in a group compete for scarce food.

Independent of population density, several factors impact the per capita growth rate. Natural catastrophes like forest fires are examples.

Diverse limiting variables can combine in intricate ways to generate different patterns of population expansion. Some populations exhibit cyclical oscillations, where the population size varies cycle by cycle in a predictable manner.

The area of the circle is 346.5 cm² while the area of the square is 272.25 cm². The figure that encloses more area is the circle.

If a wire of length 66cm is bent into the shape of a circle and square, then this length will be its circumference and perimeter, respectively.

C = 66cm = 2πr

r = 10.5 cm

P = 4s = 66cm

s = 16.5 cm

The area of the circle is given by the formula

A = πr²

A = π(10.5 cm)²

A = 346.5 cm²

So, the area of the circle is 346.5 cm².

The area of the square is given by the formula

Answer: a (x – x1) + b (y– y1) + c (z –z1) = 0.

Recall that the general form of the equation of a straight line in two dimensions is

++=0.

This can also be written in the form 

=+, where  is the gradient and  is the -intercept, which we can determine by knowing two points on the line.

If (,) is a point that lies on the line, we can determine  from the general form as =−(+); thus, the equation of the line can be written as

+−(+)=0.

The equation of the line can also be realized as a dot product of two vectors as (,)⋅(−,−)=0.

Now, if we define the position vectors,⃑=(,),⃑

then the equation of the line can be written in vector form as⃑ ⋅⃑=⃑⋅⃑,where ⃑=(,) is called a normal vector of the line and ⃑−⃑ will lie completely on the line.

A property of the dot product states that two vectors are perpendicular to each other if their dot product is zero. This equation of the line in vector form shows that the normal vector ⃑ and the vector ⃑−⃑ are perpendicular to each other by this property.

The general equation of a plane in three-dimensional space can be represented as Ax + By + Cz = D.

A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.

Where A, B, and C are coefficients and D is a constant.

The coefficients A, B, and C represent the components of the normal vector to the plane, and D represents the distance of the plane from the origin.
