The given statement is false as taking a survey on the heights of all your classmates is an example of quantitative data.
Quantitative data is data that can be measured and expressed as numbers,
such as height, weight, age, etc. Categorical data, on the other hand, consists of distinct categories or groups, such as eye color, gender, favorite color, etc.
Data can be classified into two main types: quantitative data and categorical data.
Quantitative data:
Quantitative data is numerical data that represents measurements or quantities.
It deals with things that can be measured and expressed as numbers.
For example, the heights of people, the weights of objects, the ages of individuals, and the temperatures in degrees are all examples of quantitative data.
Quantitative data can be further divided into two subtypes: discrete and continuous data.
Discrete data: Discrete data consists of whole numbers that cannot be further divided into smaller parts.
For example, the number of students in a class, the number of cars in a parking lot, and the number of books on a shelf are all examples of discrete data.
Continuous data: Continuous data consists of real numbers that can take on any value within a specific range.
For example, the height of a person can be measured as 165.5 cm, 170.2 cm, 178.9 cm, etc. These are all examples of continuous data.
Categorical data:
Categorical data, also known as qualitative data, involves the grouping of items into categories or classes.
It represents characteristics or attributes and is not numerical in nature. Categorical data is further divided into two subtypes: nominal and ordinal data.
Nominal data: Nominal data consists of categories with no intrinsic order or ranking.
For example, eye color ( blue, brown, green) and types of fruits (e.g., apple, banana, orange) are examples of nominal data.
Ordinal data: Ordinal data consists of categories with a meaningful order or ranking.
However, the differences between the categories are not quantifiable.
For instance, educational levels (elementary, middle, high school) and satisfaction levels (very satisfied, satisfied, neutral, dissatisfied, very dissatisfied) are examples of ordinal data.
The height survey of classmates, the data collected would be numerical values representing the heights of each individual.
Since heights are measured and expressed as numbers, this falls under quantitative data, not categorical data.

Consider the graph of the function below.
Which statement about the graph below is incorrect?
A. The degree of the polynomial is even.
B. There is a positive leading coefficient.
C. There is one relative minimum.
D. There is one relative maximum.
a
A
b
B
С
d
D
Answer: A) The degree of the polynomial is even
We can determine this by noticing that the end behavior is different on both sides. The left end goes downward while the right end goes upward. This opposing nature indicates we have an odd degree function like a cubic. If this was an even degree function, then the left end must also point upward to mirror the right end. That's why choice A is the final answer.
Choice B can be ruled out since it's a true statement. This is because the right end behavior goes to positive infinity. Such end behavior is tied to positive leading coefficients (whether even or odd functions, it doesn't matter).
Choice C is also true and can be ruled out because this function curve does have one relative minimum. It's the location where the curve bottoms out in the valley at around x = 3.5 or so. It's the lowest point in the neighborhood/interval of points.
Choice D can be ruled out for similar reasons as choice C, except this time we're looking at the highest point in a certain neighborhood. That highest point occurs somewhere between x = 1.5 and x = 2 where the peak of the hill is located.
To rephrase those last three paragraphs: choices B through D are true statements, so they can be ruled out.

A car manufacturing company asked 1000 people to view their latest two-door coupe available in four colors (White, Black, Cherry, and Blue).The viewers were asked to list their color preferences in order form favorite. How many ways could the colors be ordered? Of the 1000 viewers, how many would you expect to choose the following preference order: White, Black, Cherry, and Blue?
The first choice can be aby one of the 4 colors.
For each of these . . .
The 2nd choice can be any one of the 3 remaining colors.
For each of these . . .
The 3rd choice can be either one of the 2 remaining colors.
So there are (4 · 3 · 2) = 24 different ways to order the colors.
If everybody you ask thinks the same way, you'd expect all of the possible combinations to be chosen equal numbers of times . . . that is, every choice would be chosen once in every group of 24 people.
In 1,000 people, there are (1000/24) = (41 and 2/3) groups of 24 people.
So you'd expect any one possible preference order to be chosen by 41 or 42 viewers, if all of the viewers think the same way, and their preferences are perfectly random.

it is a rectangle. 18m × 4m = 72 m²
the paving costs $35 per m², and we have 72 m², so it does not take a genius to figure out what to do next ...
right : we multiply 35 by 72
35×72 = $2520

how much volume is a liter ?
a liter fits into a cube of 10cm side length.
and 1 meter = 100 cm = 10×10cm.
so, 1 m³ = 10×10×10 = 1000 such cubes of 10cm side length = 1000 liters.
the pool is 5 m × 15 m × 1.5 m = 112.5 m³ = 112500 liters
we need 2 kg salt for every 10000 liters water, so we have how many units of 10000 liters in the pool ?
112500 / 10000 = 11.25
so, we need
11.25 × 2 = 22.5 kg salt

12 seconds = 1/5 of a minute.
so, batman runs at 3 km / min (= 60×3 km/hour = 180 km/h - not possible in real life for any human being, but let's play ...) for 12 seconds = 1/5th of a minute, and so he runs 3km/5 = 600 meters in that time.
that means he has 2km - 600m = 1400m left to run in the 2 km race.
it takes him 1400/3000th of a minute (3000 m would take him the full minute)
1400 m × minute / 3000 m = 14/30 = 7/15 minutes
1/15th minute = 60 seconds / 15 = 4 seconds.
so, 7/15th of a minute = 7×4 seconds = 28 seconds.
the bionic woman runs the full 2000 m with 5 km / minute.
it takes her 2000/5000th of a minute
2000 m × minute / 5000 = 2/5th of a minute.
1/5th of a minute is 60 seconds / 5 = 12 seconds.
so, 2/5th of a minute is 12×2 = 24 seconds.
therefore, the bionic woman wins by 4 seconds (24 seconds vs. 28 seconds).
12.
there is enough food for 150 students for 5 days = 150×5 =750 "food units".
therefore, if there were only 100 students, the food would last 750/100 = 7.5 days.
and if the food runs out after 4 days it means there are
750/4 = 187.5 students (how much sense that makes to have half a student ...).

x = the workload to be done
Michelle's work speed is x/6 days
Danielle's work speed is x/4 days
on each day working together they achieve
1× x/6 + 1× x/4 of the total work load.
that is
2x/12 + 3x/12 = 5x/12
so, they need 5x/12 × a days to finish the whole x.
5x/12 × a = x
5/12 × a = 1
5a = 12
a = 12/5 = 2.4 days to finish the whole work when working together.

Which set of numbers are rational numbers but not integers whole numbers or natural numbers?
The set of numbers are rational numbers but not integers whole numbers or natural numbers are { 1/2, 1/4, 1/8}.
Hence the third option is correct.
Use the concept of rational number defined as:
A rational number is a number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
It can be represented as p/q,
Where p and q are integers and q is not equal to zero.
Examples of rational numbers include 1/2, -3/4, and 5/7.
Now analysing the given options we can see that,
The numbers 1/2, 1/4 and 1/8 are rational but not an integer.
Therefore,
The set { 1/2, 1/4, 1/8} is the correct one, which is option third.

help please i need the answer to this
Answer:
140 degrees
Step-by-step explanation:
first start by making the given angles equal each other because they are congruent.
2x+28=6x+4
Subtract 4 on both sides
2x+24=6x
subtract 2x on both sides
24=4x
divide both sides by 4 to get x
24/4=4x/4
6=x
next to find the actual number of the angle, plug 6 back into either one of the equations. Im gonna use the first one.
2x + 28
2(6) + 28
12+28= 40
Now that we have the number, we already know that a full circle is 360 degrees so half a circle is 180.
Take 40 and subtract from 180
180-40= 140
Well, m∠1 and m∠3 are congruent by the Vertical Angle Congruent Theorem (VACT). This means that because the angles are opposite of each other, their angles are the same because they are formed by the same two intersecting lines.
Because of this, we can set m∠1 and m∠3 equal to each other:
m∠1 = m∠3
(2x + 28) = (6x + 4)
2x + 28 = 6x + 4
-4x + 28 = 4
-4x = -24
-x = -6
x = 6
Knowing that x equals 6, we can use this to find m∠2. By the Supplementary Angles Theorem (SAT), angles that are on the same line add up to equal 180°. To use the SAT, we need to plug x in to find m∠1 or m∠3, because they are both the same:
x = 6
m∠1 = (2x + 28)
m∠1 = 2(6) + 28
m∠1 = 12 + 28
m∠1 = 40°
m∠3 also equals 40°.
Now that we have the value for ∠1 (or ∠3), we can use the SAT:
m∠2 + m∠3 = 180 ← You could also use m∠1, because they both equal the same!
m∠2 + 40 = 180
m∠2 = 140°
So, the measure of ∠2 is 140°.

The length of a rectangular field is 6 metres longer than its width. If the area of the field is 72 square metres, What are the width and the length of the field?
Answer:
The length is 12metres, the width is 6metres
Step-by-step explanation:
Suppose the width is x, the length is x+6
The square is 72. The square of rectangular field is equal to product of length and width.
so x(x+6)=72
x^2+6x-72=0
a=1 b=6 c=-72
D= b^2-4ac= 6*6+288= 36+288= 324
sqrtD= 18
x1= (-b-sqrtD)/2a=(-6-18)/2= -12 (it is negative, but width is only positive. So this root doesn't match)
x2=(-b+sqrtD)/2a= (-6+18)/2= 12/2=6 - the width
The length is 6+6=12

The equation be (x/2) - 3 = x/3 then, the number of x = 18.
How to estimate the value of x?To estimate the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to estimate the result.
Let x be the number
From the given information, we get
(x/2) - 3 = x/3
The set all the fractions on one side and constants on another side
(x/2) - (x/3) = 3
Multiply by LCM
3x - 18 = 2x
Add 18 to both sides
3x - 18 + 18 = 2x + 18
simplify
3x = 2x + 18
Subtract 2x from both sides
3x - 2x = 2x + 18 - 2x
x =18.
Therefore, the number is x = 18.
