FILL IN THE BLANK. Study with Quizlet and memorize flashcards containing terms like ____ are the categories by which data are grouped
Data categorization is a process of organizing and grouping data into meaningful classes or categories.
This process is often used to simplify data and make it easier to understand and analyze. Data categorization involves breaking down a large set of data into smaller, more manageable groups. For example, a company may group customers into categories based on their age, income, or location. Each group can then be analyzed separately to better understand customer behavior. Categorizing data can also help identify trends or patterns that may not be visible when looking at the data as a whole. Categorization can also be used to identify outliers or anomalies in the data. By breaking down the data into smaller groups, it becomes easier to see which elements don’t fit the pattern or are not part of the normal range. Categorizing data can be done using a variety of methods. For example, data can be divided into numerical ranges or grouped into categories such as low, medium, and high. Data can also be grouped using descriptive terms, such as customer type or product type. Once the data is categorized, calculations such as averages, medians, and modes can be used to analyze the data. This can help to identify patterns or trends that can be used to make decisions or draw conclusions.

Find the volume of the solid produced by rotating this two-dimensional shape using the axis shown.
Please help
Check the picture below.
so the solid produced will be a cylinder with a hole in the middle, like you see in the picture, hmmm so we could get its volume by simply getting the outer cylinder and subtracting the inner cylinder, or we can just get the volume of the ring on the left and multiply it by its length, so let's do the that.
\(\textit{volume of a ring}\\\\ V=\pi (R^2-r^2)~~ \begin{cases} R=\stackrel{larger}{radius}\\ r=\stackrel{smaller}{radius}\\[-0.5em] \hrulefill\\ R=3\\ r=1 \end{cases}\implies V=\pi (3^2-1^2)\implies V=8\pi \\\\\\ \stackrel{\textit{\large volume of the hollow cylinder}}{\stackrel{\textit{volume of the ring}}{(8\pi )}\qquad \stackrel{length}{(6)}\implies 48\pi ~~\approx~~150.80}\)
cardioid in the first quadrant find the area of the region cut from the first quadrant by the cardioid
The area of the region cut from the first quadrant by the cardioid is 3π/8 +1
A cardioid is a two-dimensional plane figure that has a heart-shaped curve. The equation of cardioid is r = a(1 ± sinθ) .
The area of the polar function can be calculated if the boundary condition that form the reason is given or can be found from the given information now we use the formula using the polar formula of the area as:
\(A = \int\limits^b_a {\frac{r^{2}}{2}} d\theta\)
The Area of the region cut from the first quadrant by cardioid,
\(A = \int\limits^\frac{\pi}{2}_0 {\frac{r^{2}}{2}} d\theta\)
Substituting r = 1 + sin ∅
\(A = \int\limits^\frac{\pi}{2}_0 {\frac{(1+ sin\theta)^{2}}{2}} d\theta\)
Opening square ,
\(A = \frac{1}{2}\int\limits^\frac{\pi}{2}_0 {1 +2sin\theta + sin^{2}\theta d\theta\)
=> \(A = [ \frac{1}{2} (\theta - 2cos\theta + \frac{1}{2} (\theta - \frac{1}{2}sin2\theta))]^\frac{1}{2}_{0}\)
=> 3π / 8 - (-1)
=> 3π/8 +1

A kangaroo hops 9 kilometers in 3 minutes. at this rate how far does the kangaroo travel in 2 minutes
Answer: If a kangaroo hops 9km in 3 minutes, that means he runs 3km every minute, which we can multiply by 2 in order to get 6km in the first 2 minutes. [EXTRA: In one hour, the kangaroo can hop 180km, which means his top speed is 180km/h without accounting for fatigue]

Can someone tell me what the area of this is?
Answer:
Area of Gray Triangle: 66m^2
Area of White Triangle: 30m^2
Area of Larger Triangle: 96m^2
Step-by-step explanation:
For this problem, we will find the area of the gray triangle by first finding the area of the larger triangle and subtract the area of the white triangle.
First note that the general formula for the area of a triangle is:
Area = ( 1 / 2 ) * Base * Height
Using this formula, we can find the area of the larger triangle and the area of the white triangle.
Area of Larger Triangle:
Base = 5m + 11m = 16m
Height = 12m
Area = ( 1 / 2 ) * 16m * 12m = 8m * 12m = 96m^2
Area of White Triangle:
Base = 5m
Height = 12m
Area = ( 1 / 2 ) * 5m * 12m = 5m * 6m = 30m^2
Now that we have the areas of the Larger triangle and the white triangle, we can find the area of the gray triangle by subtracting the area of the white triangle from the larger triangle:
Area of Gray Triangle:
Area = Area_Of_Larger_Triangle - Area_Of_White_Triangle
Area = 96m - 30m = 66m^2
Now we have the areas of all three triangles depicted.

marvin is trying to get to his friend's house. he walks 4 blocks north to the park, then turns right and walks 3 blocks. finally he turns right and walks 4 blocks. how far from his starting point does he wind up?
Answer: Marvin walks a total of 4 + 3 + 4 = 11 blocks.
To find how far he is from his starting point, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, the 4 blocks north and 3 blocks east form the legs of a right triangle, and the distance Marvin is from his starting point is the hypotenuse.
So we can calculate it as follows:
distance = sqrt(4^2 + 3^2) = sqrt(16 + 9) = sqrt(25) = 5
Therefore, Marvin is 5 blocks from his starting point.

Assumed it is:
f(x) = - x² + 16x - 13Converting into vertex form:
f(x) =- x² + 16x - 13 = - (x² - 16x + 64 - 64) - 13 = - (x - 8)² + 64 - 13 = - (x - 8)² + 51Given :-

As per the given Ratio difference between the amount of money spent and the amount of money saved in a week is $2.
In mathematics, what is a ratio?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other.
What exactly is the ratio formula?The ratio formula can be used to represent a ratio as a fraction. For any two quantities, say a and b, the ratio formula is a:b = a/b. Because a and b are separate amounts for two portions, the total quantity is given as (a + b).
