Homework Statement I was wondering what exactly the difference between a regular (proper? is that the term) hessian is and a bordered hessian. It is difficult to find material in the book or online at this point. I mean mathmatically so that were i to do a problem i would know the layout and...

Im sorry I just realized that this should be in Homework help. If a moderator would move it please. I am sorry for cluttering yalls forum.

Not sure if this is where I should put this but currently I am taking math for econ and we are on special determinants (jacobian, Hessian, Bordered Hessian, some Leontiff) So I have this problem in my notes that I am basically basing my exam studying around since the book isn't the best. It...

i asked my professor. She said that it was the 1.5% answer. It may be that she is filipino some of the other questions are somewhat vague in the wording as well.

according to the question in the way it is worded it only is 10.

n= 50 τ= .10 x= 10 those are the numbers i plugged in. x= number of successes. int his case a success is if the card is defective.

bump... trying to understand I am not trying to be difficult.

Values of x in what formula? The one I used? I called it a bernoulli becasue in my statistics book and because in class we used that formula and called it bernoulli

it calls it bernoulli. all i have to do is plug in the values.

hmmmm... ok i will try. Bernoulli P(x)= n!/x!(n-x)! * τ^x(1-τ)^n-x n= 50 τ= .10 x= 10 plug and chug.

Thank you for your help!

n/a. Actually I tried doing a bernoulli process which seems logical and I ended up with a result of 1.5%. I was wondering if this was accurate. I would write out the process but i don't really have the needed icons. It is like most of stats mostly basic math though with some factorials i...

Homework Statement 2. Photocards-R’-Us is a photo card printer. For this year, they have found that 10% of the cards they make are of inferior quality (blurred picture, faded colors, etc.) To attract customers to have their holiday cards printed with them, they are offering a 50% discount to...

well i actually did a hypergeometric. but otherwise multiplying it out manually it is like 25/30 * 24/29 * 23/28 etc. until you do 16 trials. im going to be asking another question in a different thread which i hope is okay?

what is it 1.4% that you reach by multiplying it out?
