The link to the motor is here: http://www.savoxusa.com/Savox_SC1256TG_Digital_Servo_p/savsc1256tg.htm In the description tab, it lists all the specs. My question is in regards to the speed specs. e.g., "Speed(@4.8V sec/60): .18" I don't understand what that is saying. 0.18 what? 0.18 sec per...

Sorry, I don't undertand what you mean here. I believe you cannot since the sign in the numerator can be +/- for A&B depending on the magnitude of w&z.

I attached a pic of a practice GRE problem. The answer is D) relationship cannot be determined. I understand this answer and it is actually what I picked, but my 2 methods of doing this problem is contradicting each other. If you use the method of plugging in random #s you'll discover...

let's say I have 10 data points. And one of my data points is 270. Then let's say two of my bins are 260-270 and 270-280. Which bin would you put the 270 in? Or would such a choice of bin range be inappropriate and new ranges have to be chosen?

Ah I see. I see. So I guess it's a subjective thing. I was given a problem with the following 10 data ptns: 289.1 269.6 270.7 277.5 279 267.8 283.7 271 261.9 282.6 I attached this problem. I was asked to "calculate and plot the histogram with 3 bins." I'm not sure what they mean by...

Thanks. The width of each bin should be the same right?

If you're given a set of data and asked to plot the histogram with x amount of bins. How do you determine which range each bin covers?

Thanks for the reply. Regarding #1, yes, that is what I used, except my (1-P(A does not happen)) is equal to the probability that one is consuming one or more insect fragments in ONE bar. I am just confused on how to apply this to ONE OR MORE bars. The probability I calculated for #2 is...

Homework Statement Data from www.centralhudsonlab.com determined the mean number of insect fragments in 225-gram chocolate bars was 14.4, but three brands had insect contamination more than twice the average. Assume the number of fragments (contaminants) follows a Poisson distribution...

I have attached the problem of interest. I think I am having trouble calculating the standard deviation for part a. D=A-B-C E(A)=10 E(B)=2 E(C)=2 sigma(A)=0.1 sigma(B)=0.05 sigma(C)=0.1 where sigma=standard deviation so to find SD...

The name.

Sorry, my example was a bad one. The actual shape I'm interested in is a trapezoid which I think, theoretically, does not have an aspect ratio defined, but for the purposes of my project I have one defined. If you imagine a trapezoid with the parallel sides oriented vertically, is there a ratio...

So if we imagine a rectangle. The aspect ratio is width/height. What if you want the ratio of the parallel sides? Is there a terminnology for that ratio?

I don't watch Mythbusters. Oh I see. I've never tried dye visualization. Have you tried smoke visualization using the smoke-wire technique in Lex Smits' Flow Visualization book? I presume that can only be done in wind tunnels?

Btw, why are flow visualization techniques easier in water tunnels?
