    Three Times the Probability Question

    i understand p=3q, meaning the probability is three times more likely to occur than not but what do you mean by another condition? Like the probability of something being 3 times as likely to NOT occur than to occur?

    Three Times the Probability Question

    hey, i came upon this question in the textbook " for what probability will an event be three times as likely to occur than not to occur?" I'm not really sure how to even go about this question so any hints or help would be appreciated -thanks

    Solving X-Intercepts of 30x^4+23x^3-29x^2+6x/x

    hey, I was given this function to analyze, and when it came to the x-intercepts i think i must be getting confused. The equation is (30x^4+23x^3-29x^2+6x)/x which i made into 30x^3+23x^2-29x+6x to make it easier to work with. Anyways i used Newton's method and let my first value =0 to...

    Why Do Logarithmic Graphs Vary Despite Similar Equations?

    I graphed y=logx+log2x and y=log2x^2 and the graphs came out a lot different. However when you simplify y=logx+log2x you actually get y=log2x^2! Any ideas about why the graphs are so different yet the equations are pretty much the same? thanx

    Finding the Point of Tangency Theoretically

    Hey I was given the question: A (x1,y1) and B (x2,y2) are two points on the parabola y=ax^2+bx+c. At what point is the tangent to the parabola parallel to the secant AB. Here are the steps I took, I am just wanting to know if I am heading in the right direction. First I just made the slope...

    Double Slit: Find Longest Wavelength

    so the biggest possible wavelength that could be created would be slightly under the width between the two slits?? and thanks a lot for your help:smile:

    Double Slit: Find Longest Wavelength

    yeah i get what that means and that theta could not be greater then 90 or less then -90, so then how do i incorperate that into the equation? and get 12 nm?:confused:

    Double Slit: Find Longest Wavelength

    Question: Calculate the longest wavelength of light falling on double slits separated by 1200nm for which there is a first-order maximum. In what part of the spectrum is the light? Answer in Book: 12nm my problem: the formula i thought you would use is...

    Interference of Light: Explaining Transparency & Opacity

    if all the light went through wouldn't it be "invisible" but how could it be opaque?, like i guess some reflected rays and incident rays would create destructive interferance, but wouldn't you still be able to see through?

    Interference of Light: Explaining Transparency & Opacity

    hey found this question in my textbook... explain using interferance why a super thin film is transparent or invisible in transmitted light but seems to be opaque when viewed with reflected light. Draw a diagram for your solution. any ideas?? i really have no idea. thanks for your time though.

    Finding the Mass of a Puck in a 2-Dimensional Collision

    bah! sorry for wasting your time, i measured the one angle wrong it was 45 instead of 54! thanks for your time though, with that change the problem does work out to the solution in the back.

    Finding the Mass of a Puck in a 2-Dimensional Collision

    yeah i assumed that it was pure elastic, the equation used was.. (m1x)(v1x) +(m2x)(v2x) = (m1x)(v1fx) +(m2x)(v2fx) (m1y)(v1y) +(m2y)(v2y) = (m1y)(v1fy) +(m2y)(v2fy)

    Finding the Mass of a Puck in a 2-Dimensional Collision

    having trouble with this problem in my textbook two pucks collide, puck A has a mass of 0.32kg, and an initial velocity of 0.04 m/s [54 N of E], and a final velocity of 0.034 m/s [N] puck B's mass is unknown but has an initial velocity of 0.038 m/s [S of W] and a final velocity of 0.028 m/s...

    Coefficient of static friction graph

    hey I did this experiment where I dragged a mass by a scale until it moved to find the static friction. Then weight was added to the mass and the process reapeated. My question when graphed and the mass or Fn on the x-axis and the applied force or Fs on the y-axis should it not plot a...
