Let's say there's a 3.9% chance I'll have green eyes, a 13% chance I will have blue skin, and an 8% chance I will have red hands. What is the percentage chance that I will have all of these attributes?

I haven’t started revising yet, I got a C on my trial, (34%) 😭. And my teacher hasn’t even finished teaching all the topics yet 😭😭

Applications are stored in binary (Base 2), and numbers can also be written in base 2. Due to this, are programs actually just very large, but not infinite numbers?

I know the results can get very large. 2^1024 is just 1kb, and a CD's can contain a number up to 2^7.16800000.

Just something interesting to think about

Upon checking on internet, got the formulae for volume of bucket as

What is bucket?

A cone of radius r1 from which the bottom part ( another cone of radius r2 ) is removed.

So, shouldn't the volume of bucket equals to volume of cone of radius r1 minus volume of another cone having radius r2. That is

Thanks in advance.

if l z+4 l <=3 then max value of l z+1 l = ?

sum of binomial coefficients of (x+2y)^n is ??

14C1 + 14C2 + 14C3 + ........... 14C13 = ?

like, which formula are we using ??

I’m currently repeating some modules from my second year of uni due to too much missing work. since i’m only going part time i want something else to occupy my time with as i feel like i’ve already wasted too much time and feel quite guilty about it (no idea why i did it, kinda feels like i lost track of my studies once a long time ago and just never recovered). i’m so sick of feeling like i’m not doing enough academically so i’ve come up with a plan for this year but i’m not sure how realistic it is. i’m doing a computer science course because i’ve always liked maths but unfortunately i feel like it involves way less maths than i was expecting. i’m planning on retaking my a level maths (didn’t actually show up to the exams when i originally had to sit them), and it’s been bugging me ever since, i feel like i’ve really let myself down by doing that. maths alone wont be an issue as i’ve gone over the content many times, I’ll just go over it again quickly to remind myself of the topics and practice exam questions. my question is how realistic is it to want to do further maths too, given that i’ll be starting this November and sitting the exams in may/june? i’m willing to spend 10 hours a day practicing if i have to, i sometimes do maths for fun already anyway. if i didn’t have two uni modules on top of it to worry about, i wouldnt be stressing, but if i decide to do it i’ll basically have the workload of 2 modules and 2 a levels ( although for the modules i’ll mainly just have to worry about assignments, as i’ve already gone through most of the content last year). for my masters i want to pick something in the field of physics, astrophysics or some sort of engineering, I feel like that’ll be impossible unless i build a stronger foundation in maths. if i put in hours of work every day, do i have any chance of finishing it all in time?

basically, i got a 6 in gcse maths (15 marks off a 7) which is like 5 marks off each paper and i want to study a level maths however i can’t do it through my school as they want a 7 so i was wondering if it would be possible to teach myself it. i wanna study economics bsc at uni and top unis require you to have a level maths. do you think it’s possible? it’s only been 2 months into y12. any tips, recommendations? a structured plan possibly? anything would be appreictaed. thanks

I understand what spans are but every time I get to a question like this I'm completely lost. I've tried to understand it but I'm struggling

Hi everyone,

I am working with some students at the moment on questions with linear and non-linear SEs. When you have found your first value (usually from a quadratic generated from both equations), is it always acceptable to substitute that value into the linear equation? Is there a case when it would be better to sub back into the other non-linear equation?

My question comes from the case where you need to prove that a line is tangent to a circle. When you find the first value, if you sub that back into the equation of the circle then you will get two values for the other coordinate. It's therefore necessary to sub back into the linear equation to prove tangency.

In the above situation, is it sufficient just to show that the quadratic produces two of the same value. Is it necessarily implied that substituting the same value into the same linear equation will only ever yield one result? Or is it necessary to go through that bit of working? Hope this part makes sense.

In summary, is it always safe to sub back into the linear equation or is there a case I haven't considered? I just want to give them the best advice. I will always encourage them to think about context but also students are naturally very efficient when studying for exams.

Hi, i am doing a project for school and have just read in an exemplar that r^2 is not a good measure for non-linear equations. All my equations are non linear. What is a good thing to use instead to calculate how well the function models the data points that is fairly easy to understand and calculate if possible?
