Which statement about histograms is true?
-Data is organized in categories
-Data appears as bars that are all about the same height
-Data is organized in equal intervals
-Data appears as bars that do not touch
Answer:
The third one is correct, the others bend the truth as they can touch but not overlap. As the third one states 'They are organized in equal intervals.' this means they share an equal growth opportunity within their own column, their own height and nominated place within the histogram. The bars are of equal width and correspond to the equal class intervals. But on rare occasions like size classes they can be shown as a wider variant within their groups. Example would be showing a wider column say on classes at a school as the width and data being achieved forces a true event of variant sizes in education upon the base of the graph, this rarely applies to staff graphs as planning for schools is a wider data share than say offices using these types of graphs. Work development would use just data percentages along with the frequencies is one example so group size are stated in the reports to support more specific data in the graphs instead.
Step-by-step explanation:
To display numerical data that has been organized into equal intervals. The bars should touch the adjacent bars but not overlap. These intervals allow you to see the frequency distribution of the data, or how many pieces of data are in each interval.

Mary bakes a chocolate cake, a vanilla cake, and a strawberry cake. Each cake is the same size. Angela eats four-eighths of the chocolate cake, two-eighths of the vanilla cake, and two-fourths of the strawberry cake. David eats one-fourth of the chocolate cake, three-eighths of the vanilla cake, and one-half of the strawberry cake. Who eats more cake, Angela or David? How much more cake? How much of each cake is left? Show all your mathematical thinking.
After Angela and David eat their portions, there is [tex]\( \frac{1}{4} \)[/tex] of the chocolate cake, [tex]\( \frac{3}{8} \)[/tex] of the vanilla cake, and [tex]\( \frac{1}{4} \)[/tex] of the strawberry cake left.
To compare how much cake Angela and David eat, let's calculate the total fraction of each cake consumed by each person:
For Angela:
- Chocolate cake: [tex]\( \frac{4}{8} = \frac{1}{2} \)[/tex]
- Vanilla cake: [tex]\( \frac{2}{8} = \frac{1}{4} \)[/tex]
- Strawberry cake: [tex]\( \frac{2}{4} = \frac{1}{2} \)[/tex]
Total cake eaten by Angela: [tex]\( \frac{1}{2} + \frac{1}{4} + \frac{1}{2} = \frac{5}{4} \)[/tex]
For David:
- Chocolate cake: [tex]\( \frac{1}{4} \)[/tex]
- Vanilla cake: [tex]\( \frac{3}{8} \)[/tex]
- Strawberry cake: [tex]\( \frac{1}{2} \)[/tex]
Total cake eaten by David: [tex]\( \frac{1}{4} + \frac{3}{8} + \frac{1}{2} = \frac{13}{8} \)[/tex]
Since [tex]\( \frac{13}{8} > \frac{5}{4} \),[/tex] David eats more cake than Angela.
To find out how much more cake David eats:
- David eats [tex]\( \frac{13}{8} - \frac{5}{4} = \frac{13}{8} - \frac{10}{8} = \frac{3}{8} \)[/tex] more cake.
To calculate how much of each cake is left:
- Chocolate cake: [tex]\( 1 - \frac{4}{8} - \frac{1}{4} = \frac{1}{4} \)[/tex]
- Vanilla cake: [tex]\( 1 - \frac{2}{8} - \frac{3}{8} = \frac{3}{8} \)[/tex]
- Strawberry cake: [tex]\( 1 - \frac{2}{4} - \frac{1}{2} = \frac{1}{4} \)[/tex]
So, after Angela and David eat their portions, there is [tex]\( \frac{1}{4} \)[/tex] of the chocolate cake, [tex]\( \frac{3}{8} \)[/tex] of the vanilla cake, and [tex]\( \frac{1}{4} \)[/tex] of the strawberry cake left.
A special form of the ellipse is called?
A circle is a special form of an ellipse, occurring when both focal points of an ellipse coincide at one point, making its eccentricity zero.
A special form of the ellipse is called a circle. This occurs when the two focal points of an ellipse coincide at a single point, which is also the center of the circle. In mathematical terms, an ellipse whose equation is scaled down in one direction, transforming it into x² + y² = a², represents a circle with center at the origin and radius a.
Kepler's first law regarding planetary orbits also refers to this special case of an ellipse. It states that planets follow an elliptical path with the Sun at one of its focal points. When both focal points are at the same location, indicative of zero eccentricity, the orbit is not elliptical but circular.
The properties of an ellipse are crucial in understanding celestial mechanics and orbits, reflecting the significance of this special case in both mathematics and astronomy.

A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?
The volume of a cylinder with a base diameter of 8ft and height of 20ft is approximately 1005.3 cubic feet.
Explanation:The volume of a cylinder can be calculated using the formula Volume = πr²h where π represents approximately the number 3.14, 'r' signifies the radius of the cylinder, and 'h' denotes the height of the cylinder.
In this case, the diameter of the cylinder is given as 8 feet, so the radius will be half of that which is 4 feet. The height is specified as 20 feet.
Substitute these values into the equation:
Volume = π * (4 ft)² * 20 ft
This simplifies to:
Volume = 3.14 * 16ft² * 20ft
By multiplying these values, we get the volume equals the product of these numbers:
Volume ≈ 1005.3 cubic ft. Hence, the volume of this cylinder to the nearest tenths is 1005.3 cubic feet.

The volume of a cylinder with an 8ft diameter and 20ft height is approximately 1005.3 cubic feet, rounded to the nearest tenths place.
To calculate the volume of a cylinder, we use the formula V = πr²h, where V represents the volume, r is the radius of the cylinder's base, and h is the height of the cylinder. Given that the diameter of the cylinder is 8ft, the radius is half of the diameter, which is 4ft. Now, using the formula:
V = πr²h
V = π(4ft)² × 20ft
V = π16ft² × 20ft
V = π 320ft³
V = 1005.31ft³
Therefore, the volume of the cylinder is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
In other terms, a function is a relationship between variables, and the type of relationship that exists between the variables defines the function, such as y = sinx and y = x +6.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the function
f(x) = 1/2 x - 5
value of function at x = 6
f(6) = (1/2)6 - 5
f(6) = 3 - 5 = -2
Hence, value of function f(x) at x = 6 will be -2.

the volume of a rectangular dog kennel is modeled by the polynomial x3 +14x2 +60+72. If the height of the kennel is modeled by (x+2) and the length and width are equal to each other, what expression could represent the dog kennel
The expression could represent the dog kennel is (x + 2)(x + 6)²
What expression could represent the dog kennel
From the question, we have the following parameters that can be used in our computation:
Volume = x³ + 14x² + 60x + 72
Height = x + 2
Dividing the Volume by the Height , we have
x² + 12x+ 36
x + 2 | x³ + 14x² + 60x + 72
x³ + 2x²
--------------------------------------------------------
12x² + 60x + 72
12x² + 24x
--------------------------------------------------------
36x + 72
36x + 72
--------------------------------------------------------
0
So, we have
x³ + 14x² + 60x + 72 = (x + 2)(x² + 12x+ 36)
Expand
x³ + 14x² + 60x + 72 = (x + 2)(x + 6)²
Hence, the expression could represent the dog kennel is (x + 2)(x + 6)²

For the polyhedron, use Euler's Formula to find the missing number. faces: __ edges: 12 vertices: 9
There are 5 faces of a given polyhedron.
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.
Euler's formula states that for a polyhedron with V vertices, E edges, and F faces,
V - E + F = 2.
In this case, we know that the polyhedron has 12 edges and 9 vertices. Let's use Euler's formula to solve for the number of faces:
9 - 12 + F = 2
F = 2 + 12 - 9
F = 5
Therefore, the polyhedron has 5 faces.
