Yes, I didn´t see the sign So it would be VT=2+3+5=10V
4. ### Engineering Series circuit problem

The first one is=-2 The second has the same polarity, and it has a rise of potential For the third, it has the same polarity and it has a rise of potential. that's correct?
5. ### Engineering Series circuit problem

VT=2-3+5=4V it's correct?
6. ### Engineering Series circuit problem

According to the Kirchoff's law of voltages: RT=6 ohms VT=? -2+3-2I+5-4I=0 6+-6I=0 6I=6 I=6/6=1A is the result right? I have some doubts in the signs of the voltages.

I made a procedure and I get that the voltage=4.8V and the current for the resistance of 3 Ohms it´s equal to 1.6A, am I right?
9. ### Engineering Parallel circuit problem

According what I understand, the 2.4A would help me to get the voltage using Voltage=(current)(resistance), or in what way can it help me?
10. ### Engineering Series and parallel circuit

I know that the sum of the currents in the circuit must be equal to zero and that the algebraic sum of the voltages must be equal to zero, I know this because I am self studying this topic, bue I don't have idea of the procedure to follow.

Homework Statement Solve the next circuit to find the voltages Homework Equations I=V/R GT=(1/R1)+(1/Rn) V=V1=V2=V3 The Attempt at a Solution My background is that I know that in a parallel circuit, the voltage for each component is the same and electric current it's equal to the sum of the...
14. ### -- cumulative distribution function, probability density

Thank you so much, I really appreciate your help and that you shared your knowledge with me!
15. ### -- cumulative distribution function, probability density

Another question, this method only applies in cases similar to this one, cases in which the probability is less than one? In a case when I already have the probability equal to one, do I only need to evaluate the function in the intervale (a,b) or I have to do another procedure?
16. ### -- cumulative distribution function, probability density

I'd be interested in doing a chart of CDF values. How can I get the values?
17. ### -- cumulative distribution function, probability density

Ok, so now I have the answer for the two questions. And for example, if I want to make a chart with the probability of the values of x, in that case, do I need to evaluate, or what I have to do?
18. ### -- cumulative distribution function, probability density

The formula for probability function is ##f(x) = Cx/4## ##f(x)=2x/4## F(x) would be ##x^2/4## and for evaluate do I need to substitute x vith the values (0,1 and 2)? Am I correct?
19. ### -- cumulative distribution function, probability density

I should multiply by 2, and if then I evaluate I get 2(2^2)/8-0=1-0=1, right?
20. ### -- cumulative distribution function, probability density

I think that the result of integrate x/4 is equal to x^2/8 +c, right? And then , the result of evaluate is equal to 1/2-0=1/2
21. ### -- cumulative distribution function, probability density

My background is that I know a little about integral calculus, I can do some indefinite integrals, I am working with the notes of my older brother and I only have the exercise but not the answer or procedure. About probability, these are my first steps on the subject and I´m doing this because I...
22. ### -- cumulative distribution function, probability density

Ok please, can you explain me in more detail? I'm a little confused about the topic and for your information I'm 17 y/o, so please take this into consideration.
23. ### -- cumulative distribution function, probability density

Yes, the probability is less than one, so how can I do to make the probabability be 1?
24. ### -- cumulative distribution function, probability density

I don´t know how to explain the reason, but the function is like it were incomplete, so the first step is to find the correct function, right? How can I do that? Or what are the steps?
25. ### -- cumulative distribution function, probability density

I suppose that the probability function is given in the exercise, and for the CDF, do I only need to solve the integral? Then, which is the next step?
26. ### -- cumulative distribution function, probability density

Homework Statement For the next probability function: f(x)=x/4 for 0<x<2 Homework Equations a) Get the probability function b) Get the cumulative distribution function The Attempt at a Solution I don´t know if the problem is well written, and for that I'm lost with the first question...

Honestly, I only used before the quadratic formula, but with its derivation I was not familiarized.
31. ### Help with the inverse of some functions

I've tried to solve it by using a factorization, but I get lost on the next steps, and I don't know how to do it exactly. I attach a file with my attempts (I don´t know if I am correct or not).
32. ### Help with the inverse of some functions

Homework Statement Hi! Does anyone know how to solve the inverse of these functions? y=(4x^2+2x-2)/(8x^2-4x+6) y=(x+1)/(x^2) Sincerely, I would appreciate your help with these exercises. The Attempt at a Solution For the first one: 8yx^2-4xy+6y=4x^2+2x-2 For the second exercise: yx^2=x+1...
