Where did the k come from? I was expecting the index to be t.

Thank you for your reply Simon. That definitely helped me understand the confidence interval. I am struggling to put it into context now. Say for example I am loading 300 lines of data into a database. Now I want to figure out the # of errors that would occur during the load (data not loaded...

Hello guys, I would like to calculate the confidence interval of the data in which the data is correct. In otherwords I would like to know how much confidence we have that the data is correct. Could anyone direct me where to start? Thank you.

Okay, so I solved for theta1 and theta2 and got the positive angles to be 3.8 rads and 5.6 rads. I got there by plotting down the corresponding angle for -0.716 rads and the other solution for this angle which would be in quadrant 3. I then added pi to that 0.716 to get 3.8 and then I subtracted...

By using the averages of high and low tide levels. The depth of the water in a seaport can be approximated by the sinusoid d=3.2sin0.166pi(t-2.5)+14.1 where d is the depth and t is the hours after midnight. if a ship needs at least 12 m of water in a seaport to dock safely, how long could the...

Ahh I think I got it... so what I am supposed to do is set the argument at pi/5 equal to pi/2 and solve for c like this... 2(pi/5 -c) = pi/2 Thanks for your help!

Yes, but the correct answer for the argument is 2(x+pi/20)

My argument is 2(x+3pi/10)

Find the equation of a sine function with its first positive maximum point at (pi/5,8) and its next minimum point at (7pi/10,-2). With the sin form as y=a*sin[b*(x-c)] + d I found: a=[max-min]/2 = 5 b= 2pi/period= 2pi/(2*[max-min])=2 d=max+min/2=3 I am having troubles determining...

Find y' y=(x2+1)7(x9+2)5(x3+1)3(x8+7)3 Is there a shortcut to doing this problem? Or do I have to actually use the product rule more than 3 times?

I have attached a file of the alcohol I need to synthesize and my futile attempt... I was thinking of using a hydration reaction to make the alcohol from the alkyne group. So basically I would mix the alkyne group with H2O and some how produce the alcohol group. Am I heading in the right...

The definition of stress (at least in my case) is a change in temperature, pressure or concentration in the system. For concentration we are talking about adding concentration to the system as a stress. I was thinking maybe we can reduce the volume to shift the equilibrium concentrations downwards.

Hi guys, I have been wondering if its possible to alter equilibrium concentrations without adding stress to the system? Thanks, Larry

Right so for M2 Vout > Vth , For triode, VDS2 < VGS2 - Vth 0 < Vout - Vth and since Vout > Vth, M2 will be in triode.

So assuming Vin = 0, for the FET to be on VGS > VTH. Where VG = VDD and VS = Vbias therefore, VDD - Vbias > VTH Vbias < VDD-VTH I don't quite see where you got Vbias > Vdd + Vth from :confused:
