Sample size=entire data set. The probability of A=55.6%, B=52.3%, and C=52.4%. The probability of AB=35.4%, and BC=39.7%. Finally, the probability of ABC=30.3%.

Assuming that the various events are "dependent", is the "conditional probability" of ABC, given G (30.3/55.6=54.5%)? Similarly, is the "conditional probability" of ABC, given AB (30.3%/35.4%=85.6%)?

Thank you in advance.

ABCDE is a convex pentagon in the plane. Through each vertex draw a straight line which cuts the pentagon into two parts of the same area. Prove that for some vertex, the line through it must intersect the "opposite side" of the pentagon. (Here the opposite side to vertex A is the CD, the opposite side to B is DE, and so on).

All my life I've known that a boy's penis is much larger in adulthood than it was in infancy, and when you consider how small a baby is in comparison to a man, it makes perfect sense. However, what they DON'T tell you is how and when it goes from the average size of 1.5" (flaccid) at birth to 3.5" at age 18, so I guess I always assumed it grew in tandem with the rest of the body -- 2" by age 4 and 3" by age 10 so it retained the same proportion with his height. However, I recently read that at the onset of puberty it is still fairly close to the size it was in infancy and early childhood (1.5" to 2"). Then, during the years of puberty, it nearly doubles in length while only the last 20% of the adult height is achieved. Freud's "latency period" in gradeschool corresponds with the lowest penis-length/body-height ratio of the lifespan because there is a lull where the sexual organs grow much slower than do the rest of the child's body. How true is this?

There you have 2 triangles of the same exact size, and the only thing they do is substitute the pieces, so logically there can't be an empty space, why is there an empty space?

Say if I was to factor x^2+2x-1 and I used the quadratic equation and I end up with 1 plus or minus i square root of 3 over 2. So if that's simplified its 1/2 Plus or minus 1/2 i square root of three. This answer is complete arbitrary but why is like i(square root of 3) over 2 = to 1/2 i square root 3. It is it because there's always a 1 infront of square root 3?

When I type in the integral of e^x^2 in Mathematica it gives me this weird answer that has erf(). I know that this indefinate integral does not actually exist but I thought I'd try it anyway. Is erf() something from complex analysis?

Put the function in the form y = a(x - h)2 + k.
What is the line of symmetry
Graph the function using the equation in part a. Explain why it is not necessary to plot points to graph when using y = a (x – h)2 + k.
In your own words, describe how this graph compares to the graph of y = x2?

Calculate the return (A) if the bank compounds quarterly (n = 4). Round your answer to the hundredth's place.
Calculate the return (A) if the bank compounds monthly (n = 12). Round your answer to the hundredth's place.
Calculate the return (A) if the bank compounds daily (n = 365). Round your answer to the hundredth's place.
What observation can you make about the size of the increase in your return as your compounding increases more frequently?
If a bank compounds continuously, then the formula takes a simpler, that is

where e is a constant and equals approximately 2.7183.
Calculate A with continuous compounding. Round your answer to the hundredth's place.
