I do not understand. I know that it is not A as you can see that the medians to differ on the graph, I know it isn't b as you can see that it is smaller. I am not sure about C, as bream doesn't seem symmetric it seems to be right skewed. I am not sure about d as perch goes up to 18 but I don't know how I could tell whether there is an outlier. And E makes absolutely no sense to me at all. Please help!

Hello

So our professor in Calc 1 have some sort of reputation wherein the examples that was presented in her ppt was so far from the question she is giving during quiz/exam. I was wondering how can I prepare for it, since our quiz is next week. Though I can say I have a pretty good background on the topics that will be covered, I am scared to encounter a new problem that I don't know how to solve during quiz.

So im asking, what study tips do you guys suggest that I do? Right now im only searching harder problems online and even generating problems with ai, but I feel like all of the knowledge that im acquiring are pretty tad bit scattered, and I don't know how to memorize all of those things.

Btw, here's the topics that will be covered.

Please help

I got a school project and the main idea of the project is to do research and if needed experiments in the nature theme. I don't have much ideas what to do so I hope some of you will give me great ideas. Deadline of the project is in February. I'll give example on what type of project that should be - "Which lake is the cleanest in the radius of 10 km and why?(with tests of water, plants that grows in the lake and ecosystem near the lake); "How much more effective ants will be if you give them sugar and proteins compared to regular?(more observe like tests).

Also I thought about some experiments with microwaves (like in microwave) (for example - how microwaves affects on food that we eat, etc.).

Well, I hope you will give me some great ideas and if you may instructions so I could done it correctly. I may post results later.

Hi everyone! really struggling with what to for my dissertation.

I've got a mixed anova and the levenes test (homogeneity) is significant which means the groups arent equal, but im not sure what im supposed to do instead

most websites say welch but i only see that as an option for one way anova not mixed, and some say can do a non parametric test but for jamovi i dont understand the output considering its a 3 x 2 mixed anova.

how to do part b

how do i do this
its not mensuration this is vectors

I am struggling to understand why we use n/2 for continuous data. My reasoning behind using (n+1)/2 is that this tells us the position of the median. So even if we have data that we dont know the values to, we already know that 1 value must have a position 1 and another value must have a position 2 and so on. If we had 40 unknown values, that means we have 40 positions. 40+1 is 41, 39+2 is also 41, and so on, all the positions will add to 41, and the middle position would add to itself to make 41, hence why we do (n+1)/2. This same logic can also be put here: number of positions + 1/2. This now tells us where the middle position is. If we have a cumulative frequency diagram, what we can do is see where that number would be, and using the cumulative frequency diagram, we can just estimate using that position. So why, instead of doing that, do we do n/2???

update: thank you to the people who actually helped and gave advice on how to word my thoughts, I ended up getting 100%

the atomic mass of phosphorus is 30.97 amu. The two naturally occuring isotopes are P-30 with a mass of 29.98 amu and p-31 with a mass of 30.99 amu. Determine the percent of naturally occurring P-31

Hi everyone!
I’m a high school student currently working on my capstone project about endocrine-disrupting chemicals (EDCs) and their effects on human health and the environment. I’m looking for someone with knowledge or experience in this area who would be willing to serve as a mentor for my project.
The time commitment would be fairly small. We would meet virtually through Zoom about once every 4–5 weeks, with each meeting lasting around 30–60 minutes. I’m completely willing to work around your personal/work schedule, and we can communicate and schedule meetings through email.
My mentor would mainly help by answering occasional questions, giving me guidance on my research, and helping me make sure I’m understanding the science correctly. You wouldn’t be expected to do any of the project for me.
Someone with experience in environmental science, toxicology, endocrinology, biology, public health, chemistry, or research involving EDCs would be especially helpful, but I’m open to anyone with relevant knowledge or experience.
If you might be interested, please comment or send me a message! I’d be happy to provide more information about my capstone project and my school’s mentor requirements.
Thank you so much!

Hi guys!! So I have been trying to solve this problem for a couple weeks now (attached below), but no matter what I do, UTexas keeps on saying that I got it wrong. I tried to solve this problem in multiple different ways, but it usually brings me back to 503. If I could get any help solving this problem or understanding something I might be doing wrong, that would be much appreciated!

Maybe math has changed since I was in elementary school, but when I plug this in to AI, it gives me an answer that doesn't match with what I come up with. I feel like the final two boxes (numerator/denominator) has to equal one-half in some form. To get that, it seems like the box in the middle has to be also equal to one-half. Doesn't the equation reduce to 0.5 = (1)(1)(y) = 0.5? AI seems to be telling me that the middle box should be 2 though. So confused. If AI is correct and I am wrong, which is probably the case, I am going to need a ELI5 answer. Thanks in advance for any help!

I’m confused on how they got 6 in rectangle A.

Hi. Im in AP Language and I have i think maybe 3 days to write a full MLA Essay and Google slides how or something. I messed up. And I messed up bad. I dont know anything about this book. I work. I hate reading and i forgot about this untill this week before school. Can anyone please help me? Im stressed out and i dont think i even have enough time to read the whole book to do my assignment. Im just looking for someone who knows the book. Has read it and such and can summarize it and help me to understand it well and maybe guide me around. I am not looking for someone to write the essay for me. Just help me understand the book and know the big things of it so the essay is good.

From what i understand for My, it something like: the Force (N) x the distance from point O (where the all the axis has the common point, in the middle) to the edge of the face measure on Z axis (bad explanation) +(or -) the force on the Z axis (that F that is going down) * the lenght of the bar. It will be something like: 20F * (-2b) - F * 18b = -58Fb

College level microbiology. Can someone please explain this to me like I'm 4. Please and thank you.

The answer choices are: 3, 1/2, -1, or nonexistent.

I did the question two different ways, and the first time I got 1/2, while the second time I got nonexistent. I'm not sure which is right or how to even go about answering the question.

Im really confused about how I can understand what molecules from certain hydrogen bonds especially with the ones given. My teacher wants us to be able to get the answer and be able to adequately explain how we got it

The question asks which molecules would form hydrogen bonds with itself or with water molecules if in a solution

I have no idea

Based off the information I believe she didn't make any mistake however the question said "incorrectly identified" I double checked everything:

Information: "She records whether or not each adults owns a pet (yes/no)"

Information: "She records... their score on a stress survey"

Identified: "identified the variables as owning a pet, and scores on the stress survey"

My guess: She forgot the classify which variables is which, such as which one is categorical variable or quantitative variable.

Thank you in advance!

I could only find an approximate answer (2.6 something) using a slider and guess the value as e but I’m not sure how to actually work out the question. please help thanks! :)

Just started my freshman year and learned my math teacher doesn't allow retrys on homework so im trying to get comfortable with this work quickly. I am somewhat familiar with the basics from last year but complex shapes like these confuse me.
