The answer is given to be 0 but I can't get to it. My answer isn't even a whole number.

So can somebody help me and provide me with a solution. I think there's something wrong with the options.

Hi I desesperatly need help, I have a presentation about Jacques Demy in a week and due to have been overworked last week I didnt have time to prepare, I'm starting now but I can't find a plan, I really can put my mind into it. I already have my problematic and I can't change it; Its ; "How does Jacques Demy manage to tackle deep and serious themes under the guise of light and entertaining films?" I was planning on using the three films "*The Umbrellas of Cherbourg", "The Young Girls of Rochefort"* and *"Donkey Skins".*

If you have any ideas about a plan, thats will be very helpful.

I already have a lot of informations and understanding about the director and its films but I really can't seem to find a plan in 2/3 parts that could compare the seriousness of the films and its light aspect.

Thank you in advance!

Want to find cointegrated pairs from a list of 50 financial instrument's prices. However, all the pairs that have been found as "cointegrated" aren't and at a loss of what's going wrong. Looking for any solutions or advice of where to look.

price of instrument 15 and 42 along with its difference (which is clearly not stationary)

Hello, I’m trying to write a paper and I’m trying to find reliable sources for the number of people who die from Ibuprofen, aspirin, viagra, benadryl - diphenhydramine, Imodium - lopermide, and other over the counter medications. When conducting the searches for some reason google and DuckDuckGo is censoring my search results and bringing up allot of article about Muslim pilgrims dying during Hajj and illicit drug overdoses when I’m typing nothing that even remotely relates to those subjects. I don’t understand what is happening. Can someone or some group of someone’s please help me find reliable sources for the number of people who die from these medications every year? Thank you!

I've been getting different answers, they're supposed to be rounded to the nearest tenth I've gotten

2: 23.3

4: 0.6

6: 0.869

- 50

12: 45.1

I don't know what I am doing wrong.

I need some help clarifying some assessment requirements

It's a paper for a positive psychology class, if that helps

I'm just having a hard time with determining the difference between two separate requirements

“Explain how sociocultural factors influence how scientists think about behavioral and mental processes within positive psychology”

“Explain how global factors influence how scientists think about behavioral and mental processes within positive psychology”

I'm not understanding the differences between global factors and sociocultural factors… because I'm feeling like the answer is the same for both of them.

Note: Emailing the professor isn't an option at this point because it needs to be in before I'd end up getting a response. know, I know… procrastination is bad.

I am given a bipartite graph (A U B, E) with the following property: for every a in A, b in B fow which ab in E, d(a) >= d(b). I must show that |A| <= |B|.

I realised that this is not true in general, since if A has as many vertices as B connected to each other and extra isolated vertices then the hypothesis is satisfied but the conclusion is wrong. Am I missing something here? So the only way I saw to prove this is further assume that the graph is connected. My idea was to try proof by contradiction, and so assume that |A| > |B| and start specifically with the graph which connects every vertex of A with at least one vertex of B and using the pigeonhole principle show that there is at least one vertex of B with degree greater than one of its connected vertices which contradicts our hypothesis and then argue that every other connected bipartite graph can be constructed from this one graph by adding edges which always causes the same issue.

Any feedback on my approach or alternative and/or better ways to prove it?

If f(x) and g(x) are differentiable functions, and given that f(1)=2 , f'(1)=5 , g'(1)=2 , and g''(1)=-1 .

what is the value of (g'/f)(1)?

I tried solving it in the two ways that our teacher taught us, but I couldn't figure it out.

Can anyone help please?

Hi, I would like to ask you: How are political candidate polls (who will win an election) different from polls about issues (abortion, gun rights, personal beliefs) and is it true that polls about issues are notoriously more difficult than candidate polls?

I've been scratching my head over this for several hours, unable to find a solution. I've scoured all corners of the internet, including ChatGPT, and nothing has returned an answer or a method to find the answer that has been 100% correct as per the given requirements. Any help would be greatly appreciated!

I would like to focus on Healthcare Utilization in 45 Least Developed Countries, specifically using Ambulatory Services as the indicator, and conduct a Panel Data Analysis (every three years or "triennial")...

I decided that my Dependent Variable is:

Y = Outpatient Visit Rates (triennial/per capita)

Then my Independent Variables are:

X1 = GNI Income (triennial/per capita/$) X2 = Adult Literacy Rate (triennial/per capita) X3 = Share of Population in Low-elevated Coastal Zones (triennial/%)

I already have data for my independent variables, which are fixed data. However, I'm confused about my X3, whether it's applicable or too broad?

Because these 45 LDCs obviously have different total populations and different percentages of populations living in coastal zones.

So, do you have any comments on whether I will have difficulty with my panel data analysis? Or will I have problems if I choose 45 LDCs and then conduct a statistical panel data analysis for each of them?

I need help! 😭
