Hi guys, Can you please post this as a separate question, not as a comment :) then it is easier for us to answer the questions and for you to see the answers too! Thanks for understanding !
Hi everyone, We are happy to answer questions again this year - just post them in the discussion board and we will try out best to answer them! Your Success Formula Team - Lena!
Hi, Ive got a stats question, just so that I get this right: Were using the students T model anytime we do statistical inference with means correct? So when I want to calculate a confidence interval for the true population mean and when I want to do a Hypothesis test about the population mean. Could anybody confirm? Is this exhaustive?
Yes that is indeed correct! Whenever you have quantitative data and you want to make an inference about the true population mean (either by doing a confidence interval or by performing a one sample t-test), you will use the Student t-distribution and hence the t-table!
Does this also apply to a situation where you deal with quantative data, but the standard deviation of the real data (so not of the sample, but sigma) is known? Or do these situations not even exist? 😅
Could someone post the written answers of the QM1 Resit 2018 vsf (EX. 12-13) on here? I really need them as I don't get exercise 12-13 and how they get the solution there. ( it's the exercise with K(cost) and demand)
Anyone offering QM1 private tutoring for the statistics part this week? Just reply to this post, thank you!
While we are fully booked for our private classes, we still have some spots available for our Stats Crash Course. :) It is a 4h class in which we go through all the important concepts and explain the theory, as well as do some practice exam-like questions!

Is there any way someone can explain the algebra on number 6 to me?
y denotes real per capita imcome and r representes average annual rate of growth.
Is it enough to just read the summaries of the stats chapters?

what Is Variablity
Were there any mistakes in the resit??? I need ONE point to pass ????
same haha
did you hear anything ?
I just don't get it, I get an outcome of 5??
For question 3, you can expand the entire equation to: 3((x^2)+2x+1) - 2x - 2 + 15 - (3x^2) + 2x - 15 = (3x^2) + 6x + 3 - 2x - 2 + 15 - (3x^2) + 2x - 15 The two (3x^2) cancel each other out The two 2x cancel each other The two 15s cancel each other And then you are left with 6x + 3 -2 = 6x +1
Can someone explain this?
Hi there :) in order to solve that question you have to make use of the price elasticity of demand (it is described in your Math reader under section on average elasticity). The formula is the following: (dq/q) / (dp/p) —> where d stands for delta, i.e. the change. In the question you are given that this price elasticity is equal to -0.2 and they want you to find out the price elasticity, which is dp in the formula. So you want to solve for dp in that formula. —> so price elasticity = (dq/q) /(dp/p) = -0.2 —> in the question your are also given the change in q (dq), which is the decrease per barrel from 31.3 to 30.5. So dq = - 0.8 —> further you have the current price (p) = 52.5 —> q, the quantity, is your total current supply, the 31.3 (OPEC) + 68.7 (other suppliers) = 100 Plugging this in the formula gives: (-0.8)/100/(dp/52.5) = -0.2 Now you have to solve this equation for dp --> dividing two fractions is the same as multiplying the reciprocal <=> (-0.8/100)*(52.5/dp) = -0.2 | / (-08/100) <=> 52.5/dp = 25 | * dp <=> 52.5 = 25dp | :25 <=> 2.1 = dp This implies that if they cut the supply from 31.3 to 30.5, the price will rise by 2.1 - so Answer D) We hope this helps!

Hey guys, that part there is wrong. The second partial derivative of xx is multiplied with the second partial derivative yy, not subtracted. Sorry!
Hi Marta!
Could someone explain how to calculate how many inflection points a certain function has? I also have problems with calculating how many stationary points there are. Thankyou!
Guys does someone have the answers key for QM1 resit in januari 2017? it would be very useful for me.. thanks !
could someone explain this ?

Does someone know why the Math exam is out of 22 and not out of 20 ?
Because they gave everyone two bonus points for the math part.
Does anyone have the answers to the course assignment of QM1? Would be most grateful. Am willing to pay.
How can I calculate my end score for the QM1 exam?
check on the portal in my grades how many bonus points you got and add them to your score
Hey everyone, can someone tell me the email address that we can complain to about the exam? I cannot find it somehow ?
its not an email adress its a link on the student portal called "exam comments"
Also can someone tell me why answer D is wrong? For question 40. Thanks
it is not wrong they published that two answers are right for question 40 (see answerkey)

How did you find the exam guys?
Hi, Does anyone know how to calculate Q20) from the trial exam? Thanks X

Hey, I also don't get how to go from the second to last step to the last step. Anyone can explain?
It's a bit confusing, but basically you have to rewrite it and see that 0.65 delta x / 5 = 0.13 delta x, same for the y; 0.29 delta y / 3 = 0.097 delta y
Last minute help needed!! When I calculate the standard deviation, do I really subtract the mean from every value?? Thank you!!

You are welcome - success for the exam today! :)
Thanks a lot!! Is there no faster way to get to the standard deviation? :)
Trial Exam Math 9) Could anyone explain to me how to derive this function to check on the extreme points? Thanks

A collegue of yours gave a different answer B... could you let me know what is the right answer?
B is the right answer
can someone help me with question 30? I don't know where to start and what to do...
Hi David, Please find attached my notes. In Q 30, they are looking for the conditional probability. Hope that helps! Best, Your Success Formula Team - Lena
Yeah perfect thanks :) took a few detours to understand that you need to combine conditional probability with z scores ?

Wat does the sign mean that looks like aan E? (Domain x E R)
It just means that x must be a real number. That's how we used to write it in my high school
It means “element of” so if you write x e(the weird one) R - it means element of all real numbers, as Angie also mentioned :)
how do you get to P ?
You have to set the derivative equals to the slope of the tangent line. The slope is -1 (p-x). So you find x=1. Tangent line is y-1 = -1(x-1), so p = 2 (y = -x + 2)
It's not "different" instead of equal ?
yes you're right !

Is mastery just 100% if you have 1/1 or should you look at the percentages in Sowiso and MSL? I know that in general I had around 94% everytime, however at my scores it does say 1/1. Should I fill in 94 or a 100?
How do you get to the final result? I get to x = y^2 / y^2 -1
Hi Anonymous Dice, What you got is correct and then they rearrange it further — I have done the calculation for you. Don’t ask me why they rearrange it - i don’t know, it is unnecessary for me ??‍♀️??‍♀️ Best, Your Success Formula Team - Lena
How did you get to this answer? Thank you ! Good luck for the preparation.
