    Undergrad Optimizing Defective Rates with Bayes' Formula

    Okay, I made it way too complicated in my head. Thank you very much!

    Undergrad Optimizing Defective Rates with Bayes' Formula

    I have might been sitting with this problem for too long, if it something I should be able to do "in my head". You wrote I should just change some stuff around in question 2), but that is also dependent on the conditional probability from question 1)?

    Undergrad Optimizing Defective Rates with Bayes' Formula

    Oh right, so basically I will hand it in as A_D = 1*0.03 = 3.0% B_D = 1.8*0.03 = 5.4% C_D = 1.5*0.03 = 4.5 %

    Undergrad Optimizing Defective Rates with Bayes' Formula

    I express the defection rates of B and C in terms of A's defection rate (x1). From your explanations I think it's correct, as 2) gives the same answer when I plug it in.

    Undergrad Optimizing Defective Rates with Bayes' Formula

    Alright, that was my conclusion as well. If they were all different, one would have to remain the same. So is my result in the last image correct? It does ensure that they are all equal to 1/3.

    Undergrad Optimizing Defective Rates with Bayes' Formula

    Thanks for your replies! I might misunderstand you, but it says the defective rates can only increase, so how can we keep B and C constant?

    Undergrad Optimizing Defective Rates with Bayes' Formula

    As I understand, it wants me to minimize the defective rate overall while ensuring the companies have the same probability of being identified with a defect apparatus. Don't know if that helps.

    Undergrad Optimizing Defective Rates with Bayes' Formula

    Hello! I'm sitting with a problem that is causing me some troubles.. First part is using Bayes formula. We have 3 companies that produce some apparatus. Each company has some defective percentage. Company Produced (%) Defective (%) A 45 3 B 25 6 C 30 5 1) Suppose we pick up a...

    Decrease of Solar radius per year using Virial Theorem

    Ahh, okay we always write it with other symbols. I have no idea why they changed it, but naturally I know what luminosity is.. :woot: Alright, so I set it equal LG = 3.839 * 1026 W and solve for(dR/dt)? Thank you so much for explaining this!

    Decrease of Solar radius per year using Virial Theorem

    No, I have no idea. I looking for it in the Virial Theorem section, but without any luck. It hasn't been mentioned in the chapter we've been reading this week.

    Decrease of Solar radius per year using Virial Theorem

    Right, so I want to solve for (dR/dt) to get the change over time, so I can't multiply by dt on both sides to get energy on the left hand side. Not quite sure what to do with LG

    Ahh it is J / s right?

    Decrease of Solar radius per year using Virial Theorem

    I know it's energy, if that's what you're hinting :D

    Decrease of Solar radius per year using Virial Theorem

    Hello, I am trying to solve this question: Assume that the Sun's energy production doesn't happen by fusion processes, but is caused by a slow compression and that the radiated energy can be described by the Virial Theorem: $$L_G = - \frac{1}{2} \frac{GM^2}{R^2} \frac{dR}{dt} $$ How much must...

    Extinction law -- How big is the extinction in the H-band?

    Yes, I figured it out :)
