On an engine, the timing chain has colored links, and you have to line up these colored links on timing marks on the engine. There's typically marks on sprockets, bearing caps, gears. A understand that you have to line these up in order to get proper timing. I understand that is the reason why...

The solution code is like this-: ACTIVITIES_WEIGHTAGE=30.0 SPORTS_WEIGHTAGE=20.0 EXAMS_WEIGHTAGE=50.0 EXAMS_TOTAL=200.0 ACTIVITIES_TOTAL=60.0 SPORTS_TOTAL=50.0 exam_score1=int(input("Enter marks in first examinations out of 100"))...

To approach this, I first assumed the case when the students attempts all the remaining questions. Probability that they gain 4 marks for a guess = ##\frac 1 4## Probability that they lose 1 for a guess = ##\frac 3 4## Now let us say the number of correct guesses = ##r## Now we should have at...

Greetings, I am a twelve year old currently attending an academically selective school, intrigued by theoretical astrophysics and working on laying the ground for my mathematical intuition (which I am lacking greatly). At the succession of each science unit, we must undertake an assessment of 25...

I am a physicist wannabe but have come full circle to the realisation that average marks in physics isn't going to cut it in this field. My laziness in my critical thinking and life in general, my focus on marks (which haven't produced marks anyway), and lack of engagement with anything but...

I'm confused as to how far apart the hash marks should be on a minkowski spacetime diagram that shows the rocket frame overlapped over the lab frame. Should the hash marks that represent space in the rocket frame be spaced apart exactly the same length as the hash marks that represent space in...

I got low marks in all my exams and i am sure i will continue to do so. Now what will happen to me?

My teacher says I have to solve all the limits at once, but I don't understand why it is mathematically incorrect to solve one limit before the other. The test is here:

Hi, I have been upset lately due to getting a low mark in one of the most important courses in my life. I am a fourth year nuclear engineering student. I have been an average student since high school. my uni gpa is average too. I don't know if it's the way I study is what I am doing wrong or...

Homework Statement Homework EquationsThe Attempt at a Solution I'd first like to apologise in advance because I may be making a few more threads like this. I have an exam on Tuesday and am looking at past papers which don't have any answers for me to check whether I'm doing the right thing...

I've looked around for this and so far haven't found anything close enough to what I'm after. In matplotlib, I want to get a specific tick on the x-axis to label a particular value. I know how to use axvline to get a vertical line marking that point, which is good, and I know how to add...

I am a computer engineering student at UofT. Last semester, my marks were all A's/A+'s in math and computer science, but I got a B- in physics and some other course (team project screwed my marks over, we got a 50% but I managed to pull my marks up by acing the final) which killed my GPA...

Hi guys, I am currently in the "ib program" and my grade 11 mid terms marks are chem:74% biology:77% English:83% French:75% I do not think I can bring my chem mark up to an 80% by finals This is worrying me so much.. I haven't really tried this first semester and my marks have dropped...

heyy im from delhi, india. i completed my 12th grade 2 years ago with science subjects and scored 44% overall. to improve my marks, i did my 12th grade again by giving 'improvement examinations' (improvement examinations are normal 12th grade/high school final exams that take place every...

I'm in year 3 currently. I'll be applying for grad school in the US in the fall, and based on what I've seen on the internet and heard from others, most applications are due in December, some early January. My school is on a semester system, and our fall term grades aren't made official until...

Hello, I'm 16, live in Australia and am senior in high school. I do the highest levels of Mathematics which i can at school, and thoroughly enjoy them! I enjoy them so much infact, that i was considering math as a career. Here's my dilemma, after observing my marks i noted that i am hovering...

Hi, This may sound like a weird question. I have extremely painful burning sensation on my lower buttocks and down the back of my upper leg. I have been to the doctor and he has no answers. Is it possible that I came in contact with some substance that could cause the extreme burning, but...

Hi all, I recently got my grades back for the fall term, and I already knew they wouldn't be very good by the way the exams went (74 in rings/fields, 80 in real analysis/metric spaces). I'm worried that they will impact my chances for graduate school, and I am wondering about other people's...

hi, i am currently in grade 12 (last year of high school) i really want to apply to physics (i live in Canada, Ontario), my school level insanely high, and and i am passing math with an average of about 55%. i hate chemistery but i still have to take it as it is required. i am also getting a...

1) in my exams there were 3 simple questions on integration carrying 5 marks each, i solved them correctly but the only mistake i did was at the end of each step i didnt write "+c" like for example the final step of an integration problem is suppose say: x2+9x2+c so how much marks i will...

I am having some trouble deciphering how to plot a histogram in MATLAB. My main problem is that I want the x-axis labels to line up with the tick marks. I do NOT want the labels centered and under the bars themselves. I have been looking into the histc() function...

The minute hand of a 12 hour analog clock is situated precisely on a minute mark, while the hour hand is situated exactly 2 minute marks behind the minute hand. What time is it? Note: For purposes of the problem, each hour mark is deemed as a valid minute mark.

I'm trying to add a tick mark at the origin of a plot in mathematica, but seem to be having trouble. Any advice? My command looks like this right now: Plot[S[v], {v, 0, 6}, PlotRange -> All, AxesLabel -> {"Voltage", "Current"}, Ticks -> {{{6,V_th},{{0,"0"},{1,I_max}}}] The tick marks at...

just out of curiosity, has anyone ever received good marks on their final exams by cramming all the material you learned for the class for two days? I crammed once for a calculus class, and its no walk in the park I tell ya.

I'm hoping that I can get some honest answers here. I'll start off by saying that I wanted to be a doctor since I was very small, and that it is like a dream job for me. I have a passion for biology and health. But the only thing standing in my way is grades. I am not a bad student but I'm not a...

I have come to the realisation that most students seem to keen up so much when a piece of work is going to be marked and counted towards their final grade (compared to when the work is not assessable). It draws a very close resemblance to people keening up when doing a job that they are paid to...

Hi everybody. I'm just wondering what kind of marks (in %) would be enough to consider a career in Theoretical Physics. It's an area I've become interested in, though I'm only in Grade 10, so things might change by the end of high school. I have a 97% in "Pure" Math 10, which is the toughest...
