Ok, thank you so much for the help.

10V-(6 ohms*I)=0 10V=6 ohms*I I=10V/6 Ohms I=1.66 A

Yes, I didn´t see the sign So it would be VT=2+3+5=10V

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?

VT=2-3+5=4V it's correct?

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.

If all it's Ok, I think that this exercise is solved, thanks for your help with this problem.

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?

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?

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.

Thank you so much, I really appreciate your help and that you shared your knowledge with me!

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?

I'd be interested in doing a chart of CDF values. How can I get the values?

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?

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?

I should multiply by 2, and if then I evaluate I get 2(2^2)/8-0=1-0=1, right?

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

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...

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.

Yes, the probability is less than one, so how can I do to make the probabability be 1?

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?

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?

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...

Now I share the answer for the first exercise, I expect don't have mistakes. y(x) = (2 x+1)/(4 (2 x-1))±sqrt(-44 x^2+12 x+9)/(4 (2 x-1))

Ok, I think I have the answer for the second exercise, and now I share with you y(x)=(1+-sqrt(4x+1))/2x

So you are telling me that I can solve it by using the quadratic formula and finding the valuex of x?

Honestly, I only used before the quadratic formula, but with its derivation I was not familiarized.

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).
