in wich of the tables are x and y inversely proportional

x=1,3,4,24
y=24,8,6,1
D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2

Answers

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values

Aada saves and spends her salary at a ratio of 9:4. Find the percentage of her saving.

Answers

Answer: 225%
As you can see, 9 is greater than 4, so the percentage would be greater than 100%. You have to do 9 divided by 4 to find the percentage. Once you do that, you'll get 2.25, but that's just the decimal form. To find the percentage, you have to multiply by 100 which gives you 225%.

What is the definition of a four-dimensional (4-D) shape?

Answers

A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).

A salesman at a jewelry store gets paid 30% of the selling price of each piece of jewelry he sells. About how much will he get paid for selling a ring that costs $495?

Answers

Answer:

$148.50

Step-by-step explanation:

Concepts

To find <x% of y> or a certain percent of a number, you have to:

Convert the percent into a decimal (by moving the decimal point two place to the left. e.g. if the percent was 25%, it would be 0.25.)Multiply that decimal by the other number

Application

In this case, we're asked to find how much the salesman makes, knowing that makes 30% of price of the item he sells. We're given the price of one item as $495. Now, we have to multiply 30% by 495 by follow the two aforementioned steps.

Solution

Step 1: Convert 30% into a decimal

30%0.30

Step 2: Multiply 0.30 by 495.

0.3 · 495$148.50

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

How to simplify the expression?

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Here ‘j’ is the variable.

To find ‘j’ we just need to 12 from 25.

So, 25 - 12 = 13

Hence, now we know that ‘j’ is equal to 13.

Deanna gets 3 problems incorrect on her quiz. Her score is 85%. How many questions are on the quiz?

Answers

Let's start by seeing what percentage is incorrect.

100-85=15

So, 15% is incorrect when answering 3 problems wrong. So let's divide 15 by 3.

15÷3=5

So, each problem is worth 5%, let's divide 100 by 5. The reason I'm doing this is to find out how many questions are on the quiz since if you got them all right, it's 100.

100÷5

There are 20 questions, let's make sure this is correct.

If she got 3 wrong, she got 17 right. Let's calculate her percentage and make sure it is the right one.

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!

Answers

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.

2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.

3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.

4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).

5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.

6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.

7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

$\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}$

♥️ $\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}$

To create a box plot for this data set, we need to find the minimum value, maximum value, median, and quartiles.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38

The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.

In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

Hey, do you guys like my speech!??? I wrote it and if you have any pointers on how to make is better :)???Classical Music is the type of music that is very serious or conventional, which follows long-established principles different from jazz. I believe it is very important for almost everyone, as it helps people feel relaxed and rejuvenate their spirits. It helps in experiencing a huge gradual range of emotions, such as despair, love, happiness, and even sadness. This specific type of music is important as it serves various purposes; it helps people in getting away from all the confusion in life and focus on lifes goals, such as a job opportunity, or just an accomplishment.This fascinating type of music helps put me into a zone to just completely focus on whatever subject I need to. I believe Classical Music is something most people find beautiful, and I think others may not even understand. My thoughts to do this speech immediately went to classical music and how I find it not just beautiful, but emotionally sole-shatteringly sometimes. Classical music, I believe, has the power of moving someone emotionally without speaking a word, it isn't just noises thrown together, it's something that a person has learned to create so carefully. Each note is put together to make the perfect piece. It can feature one instrument or multiple and can be replicated so that it's never lost.There is a world-renowned composer, which I am sure all of you know. His name is Ludwig van Beethoven. Beethoven was a German composer and pianist, born December 1770, Bonn, Germany. Beethoven was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western classical music. His works span the transition from the classical period to the romantic era in classical music. They are famous for their great strength to empower you in his pieces of music. My most personal favorite is Beethoven Moonlight Sonata - Piano Sonata No. 14, this piece was designed to let you focus. Beethoven music you can listen to for hours, they are absolutely fascinating to hear and almost feel how wonderful it is.Classical music expresses the deepest thoughts of our civilization. Composers paint an image of the society and times within which they lived. you'll be able to expertise the greatness and achievements of another generation through its music. If we tend to dont die this unbelievable thread of artistic living history that binds the United States of America one generation to the opposite then we diminish all of the humanity that came before us and definitely leave an open hole for the future. we tend to bear in mind however necessary the musical genre is in a very world that perpetually appears as it stands on the precipice of a scarily dark chasm. Music continues to bridge the nice divide between cultures and countries. It will bring hope for peace within the darkest of times.Classical music has its own noble history just like the remainder of the music types. each culture and tradition has its own type of classical music that competes with the help of various instruments for instance Indians, Chinese, Arabs, and Europeans had their own traditions for classical music. The genre may be a broad, somewhat inexact term, pertaining to music produced, or frozen within the traditions of art, religion, and concert music. Music is classical if it includes a number of the subsequent features: a learned tradition, support from the church or government, or larger cultural capital. genre is additionally delineated as complex, lasting, transcendent, and abstract.Thank you.

She threw a kitchen towel at him, and it unfurled in midair and landed on his head, draping itself over the brim of his cap.Okay, okay, I'll do it.Ji-Suk had made a name for herself in Kansas City, especially after a local magazine wrote a big cover story when she left her job as an attorney at a law firm after seven years to start a food truck business. If her own mother had still been alive, she would have been quite upset with Ji-Suk for that. Her mother had spent years learning to speak relatively good English, and shed been determined to make sure Ji-Suk graduated from a respectable college and became a lawyer. Even though she'd made Ji-Suk take Korean lessons every Saturday morning followed by violin lessons in the afternoonand cooked kimchi and other Korean delicacies with her at least once a weekJi-Suk's mother had wanted her to succeed by American standards. And she had. She'd become a lawyer, just like her mother wanted, but she'd also learned to love burnt end barbecue, a local culinary favorite. She was an avid fan of the Kansas City Chiefs. She even loved playing softball; she had a wickedly fast windmill pitch, having played throughout college and graduate school and on the law firm's recreational team. Ji-Suk had succeeded by American standards in ways her mother couldn't have imagined, and in ways her mother probably didn't want, but Ji-Suk couldn't do anything about that. She was American, just as much as she was Korean, and even though her mother wouldn't have wanted her to do it, starting the food truck was Ji-Suk's way of honoring her mother and showing that she valued what her mother had taught her.Still, she was determined not to force Seo-Jun to do the things her mother had forced her to do. He wouldn't have to take violin lessons, nor would he have to learn Korean. She was more than willing to let him take Korean lessons if he showed any interest, but he never did.She wasn't sure, however, whether she was doing the right thing, as Seo-Jun didn't seem to want to play sports, nor did he have any serious hobbies. He got by in school, but he didnt apply himself. He was mostly interested in his friends. She hadn't been any different at his age, and she would have spent most of her time with her friends, too, but her mother would never have allowed it.Seo-Jun finished chopping a stalk of scallions and put down his knife in order to glance at his phone.
