Q1: Two jokers are added to a standard 52 card deck. The deck is then shuffled, what is the probability that someone draws 5 cards and two of those 5 cards happen to be both jokers. is this what you do? 5C3 / 54C5 ? This one looks like a hypergeometric distribution where you have dependent...

What exactly is the difference between the mean waiting time and the median waiting time for an exponential distribution? I'm looking for a slightly intuitive understanding. I know the formulae, with the mean waiting time as 1/λ and the median as ln2/λ (which I notice is also the formula for...

I'm sorry, I just realized I put this in the wrong subsection. While I figure out how to fix that, please have a look anyway. __ Homework Statement Given x \inℝ And s =\frac{4(x^{2}) + 3}{2x-1} Prove that s^{2} -4s - 12 ≥ 0 Homework Equations The discriminant Δ, (in order for which to be...

Homework Statement This is a piecewise function; Part 1: y = 360(1.029x) For domain 0 < x < 54 Find the area from x=24 to 54 hours And Part 2: y = 3900(0.98x) + 472 For domain 54 < x < 144 Find the area from x=54 to 120 Homework Equations...

Homework Statement This is the function: y= 360(1.0297^x) Find the area between x=24, and x=48. The graph looks like this: http://tinypic.com/r/30w4bjp/5 And the points are: 24, 740.8379 30, 883.0544 36, 1052.572 42, 1254.631 48, 1495.479 ASAP svp. =]Homework Equations Ah... You know it =/...

Here's another idea I can investigate if any factors can affect the heat capacity of matter without a change of state.

Homework Statement ^Not quite relevant to follow the template, unfortunately. I need to do an investigation in Physics (not just a research paper) and I need help finding a suitable topic Some of the good ones that have been done so far mainly involved looking at the aerodynamics of aeroplanes...

I find this an interesting idea. It also has scope for me to conduct a few experiments for study.

I'm afraid the template for homework help doesn't quite apply here since my problem is the lack of a problem in itself. I'm an International Baccalaureate student, and I've decided to do a research topic (about 4000 words) on physics. I need help with this. I'm looking for suggestions for...

Homework Statement The problem is the same as the title; to find the relation between wave speed and tension for a standing wave in a string. (Fixed ends) Given data (from the experiment) String length = 1.62m, mass is negligible Frequency = 48.2 Hz Basically one end of the string was...
