Data Presentation - Tables
Tables are a useful way to organize information using rows and columns. Tables are a versatile organization tool and can be used to communicate information on their own, or they can be used to accompany another data representation type (like a graph). Tables support a variety of parameters and can be used to keep track of frequencies, variable associations, and more.
For example, given below are the weights of 20 students in grade 10:
50, 45, 48, 39, 40, 48, 54, 50, 48, 48, \\ 50, 39, 41, 46, 44, 43, 54, 57, 60, 45.
50,45,48,39,40,48,54,50,48,48,
50,39,41,46,44,43,54,57,60,45.
To find the frequency of 4848 in this data, count the number of times that 4848 appears in the list. There are 44 students that have this weight.
The list above has information about the weight of 2020 students, and since the data has been arranged haphazardly, it is difficult to classify the students properly.
To make the information more clear, tabulate the given data.
\begin{array}{c}\\ \text{Weights in kg} & & & \text{Frequency} \\ 39 & & & 2 \\ 40 & & & 1 \\ 41 & & & 1 \\ 43 & & & 1 \\ 44 & & & 1 \\ 45 & & & 2 \\ 46 & & & 1 \\ 48 & & & 4 \\ 50 & & & 3 \\ 54 & & & 2 \\ 57 & & & 1 \\ 60 & & & 1 \end{array}

Examples of data presentation in math includes: Tables, Bar Graphs, Line Graphs, Pie Charts and Scatter Plots
1. Tables: Tables are used to organize and present data in rows and columns. They are effective for comparing values and showing relationships between different sets of data.
2. Bar Graphs: Bar graphs represent data using rectangular bars of varying lengths or heights. They are useful for comparing quantities across different categories.
3. Line Graphs: Line graphs show data points connected by line segments. They are commonly used to display trends and changes in data over time.
4. Pie Charts: Pie charts represent data as a circle divided into sectors, with each sector representing a proportion of the whole. They are effective for showing proportions and percentages.
5. Scatter Plots: Scatter plots display individual data points on a two-dimensional graph. They are useful for identifying relationships and correlations between two variables.

a) What is the area of the label of a can with dimensions as shown?
cm2
b) What is the total surface area of the can?
cm2
c) What is the volume of the soup can?
cm2
Answer:
Part a) The Labeled part of the Can ⇒ 263.76 cm^2
Part b) The Surface Area of the Can is ⇒ 340.69 cm^2
Part c) The Volume of the Can is ⇒ 38.465 * 12 = 461.58 cm^2
Step-by-step explanation:
~ If the dimensions of this can is 12 centimeters by 7 centimeters... ~
Part a)
1. Now a can is in the shape of a cylinder, thus the Base would act as a circle. That being said, 7 centimeters acts as the diameter of this circle.
2. If we were to unravel the middle of the can, it would be that this circular portion turns out of be a rectangle, with dimensions of the height of the cylinder, by the circumference of the Base of the cylinder. The circumference can be calculated by πd where d is the diameter ⇒ 3.14 * 7 ⇒ 21.98 cm. Thus the dimensions of this middle part of the can is 21.98 by 12 ⇒ 21.98 * 12 ⇒ 263.76 cm^2.
The Labeled part of the Can ⇒ 263.76 cm^2
Part b)
1. We know previously, that 7 centimeters acts as the diameter of this circle, so the radius must be half of that, which is 7/2 ⇒ 3.5 cm. Now we can apply the area of a circle formula πr^2 where r ⇒ radius, such that: 3.14 * ( 3.5 )^2 ⇒ 3.14 * 12.25 ⇒ 38.465 cm^2.
2. Knowing that the Base of this can is 38.465 cm^2, multiply this value by 2 to get the surface area of the two bases, provided they are equivalent: 38.465 * 2 ⇒ 76.93 cm^2
3. We know that this labeled section of the can is ⇒ 263.76 cm^2. This means that The Surface Area of the Can is ⇒ 263.76 + 76.93 = 340.69 cm^2
Part c )
The volume of the can is calculated by Base * height. We know from the previous questions that the Base ⇒ 38.465, and the height was given to be 12 centimeters. This means that The Volume of the Can is ⇒ 38.465 * 12 = 461.58 cm^2

A regular hexagon is rotated about its center. Which degree measure will carry the regular hexagon onto itself ?
Final answer:
A regular hexagon will coincide with itself when rotated by angles of 60 degrees, or multiples of it like 120, 180, 240, 300, and 360 degrees, because these are the angles of rotational symmetry for a hexagon.
Explanation:
A regular hexagon has six sides of equal length and interior angles that are also equal. When a regular hexagon is rotated about its center, there are specific degree measures for which it will fit exactly onto itself, known as the angles of rotational symmetry. Since a full rotation measures 360 degrees and a hexagon has six sides, we can divide 360 degrees by the number of sides to find the smallest angle of rotation that will carry the regular hexagon onto itself.
The calculation is 360 ÷ 6 = 60 degrees. Therefore, a regular hexagon will coincide with itself every 60-degree turn. Other angles that will carry the hexagon onto itself are multiples of 60 degrees: 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees (a full rotation).
Every day the teacher has her class of ten students line up for lunch. How many different ways can the students line up?
3,628,800
100
55
90
The number of different ways ten students can line up for lunch is 3,628,800, which is found by calculating the factorial of 10 (10!).
The question asks how many different ways ten students can line up for lunch. This is a problem of calculating permutations without repetition, as each student is unique and once a student takes a place in line, they cannot be in another position at the same time. The formula to calculate the number of permutations for 'n' unique items is n! (n factorial), which is defined as the product of all positive integers from 1 to n.
In this case, 'n' is 10 because there are 10 students. Therefore, the calculation is 10! = 3,628,800 different ways.

Which function is equivalent to y = 3(x + 2)2 + 7?
A y = 3x2 + 12x + 33
B y = 3x2 + 12x + 19
C y = 3x2 + 19
D y = 3x² + 33
Answer:
B y = 3x^2 + 12x + 19
Step-by-step explanation:
y = 3(x + 2)^2 + 7
To expand the square of the binomial,
either recall that (a + b)^2 = a^2 + 2ab + b^2, or use FOIL.
y = 3(x^2 + 4x + 4) + 7
y = 3x^2 + 12x + 12 + 7
y = 3x^2 + 12x + 19
Answer: B y = 3x^2 + 12x + 19
Final answer:
After expanding and simplifying the given function, we find that the equivalent function is y = 3x^2 + 12x + 19, which corresponds to option B.
Explanation:
The task is to find the equivalent function to y = 3(x + 2)2 + 7. We'll start by expanding the square and then distributing the 3 across the resultant terms.
First, expand the square: (x + 2)2 = x2 + 4x + 4.
Next, distribute the 3: 3(x2 + 4x + 4) = 3x2 + 12x + 12.
Finally, add the 7 to complete the expansion: 3x2 + 12x + 12 + 7 = 3x2 + 12x + 19.
Therefore, the equivalent function is B y = 3x2 + 12x + 19.

object is on the ground 58.5 m away from the building on a line directly beneath the person. Compute
the angle of depression of the person's line of sight to the object on the ground.
Answer:
[tex]\theta = 12.16^0.[/tex]
Step-by-step explanation:
Given,
Height = 12.6 m
Object distance from the person = 58.5 m
Angle of depression
[tex]tan \theta = \dfrac{P}{B}[/tex]
[tex]tan \theta = \dfrac{12.6}{58.5}[/tex]
[tex]tan \theta = 0.2154[/tex]
[tex]\theta = 12.16^0[/tex]
Hence, angle of depression is equal to [tex]\theta = 12.16^0.[/tex]
The angle of depression of the person's line of sight to the object on the ground is 12.15°.
The information forms a right angle triangle. The person eyes above the ground is the opposite side of the triangle. The object distance from the building in line of the sight is the adjacent side of the right angle triangle.
Therefore,
using trigonometric ratio,
tan Ф = opposite /adjacent
tan Ф = 12.6 / 58.5
tan Ф = 0.21538461538

(To find the x-intercept, substitut in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y. As shown in the pictur)
The x-intercept and y-intercept of the equation will be (8, 0) and (0, 20).
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The school band is selling sweatshirts and baseball caps to raise $2000 to attend a band competition.
Sweatshirts cost $25 each and baseball caps cost $10 each.
The equation 25x + 10y = 2000 models this situation.
Where x is the number of sweatshirts sold and y is the number of baseball caps sold.
Then the x-intercept will be
25x = 200
x = 8
The x-intercept will be (8, 0).
And the y-intercept will be
10y = 200
y = 20
The y-intercept will be (0, 20).
The x-intercept and y-intercept of the equation will be (8, 0) and (0, 20).
