Of Course!

Thanks, will do!

Glad it was helpful!

Yes for sure, I will help you. This evening I will make a video of how to solve this problem. Besides the concept of uniform distribution, you know integration, am I right?

I have posted a solution to this question in ua-cam.com/video/w-eV621AorY/v-deo.html

Good to know from one of my number one subscribers 👍

I’m glad you have found it useful. Please feel free of ask any question in the comments.

Hi Bashiru, Thanks for your interest. I understand your problem. Every calculator is different but every scientific or financial calculator has a key for the exponential function. You can see the following video in which I explain how to use that ba II + calculator of Texas instrument for solving a similar problem: ua-cam.com/video/NtmBrDzoKRI/v-deo.html. This is a long video, but the explanation of the calculator is from about minute 18

😋I m glad you’ve found it useful

Thanks. I am Hernando. If you have further questions do not hesitate and type them in the comments. I’m looking for students questions for making videos of interest. A little about me can be found in the Wikipedia page en.m.wikipedia.org/wiki/Hernando_Burgos-Soto

Thanks for sharing. If the function does not have indetermination, just make a substitution, example g(1). If the function is a ratio with an indetermination 0/0, as the one in the example, you cannot make the substitution. So, you will need to use the graph of the function and click on the point of the graph that has x coordinate given by the value x approaches.

Glad you think so!

I’m really glad you like it

it really helped me in my final exam @@theaplusproject1

You are really welcome! Yes, I have followed the notation of some textbooks (Groebner's textbook from Pearson for example) that show the difference between the average (lambda) in the segment of the information of the question, and the average (mu) in the interval of the actual question of the problem. Some other classical textbooks only consider in their explanation the average in the actual question of the problem, and for them, mu and lambda are the same thing. So we need to be careful what type of notation your book is using. Thanks a lot for your participation.

Thank you so much for your time giving further information. good day Sir @@theaplusproject1

Hola Adrianmonk, gracias por tu pregunta y por tu interés en el tema. Por supuesto una vez la teoría de conjunto entra en escena el concepto que ahora conocemos como función queda casi por completo determinado. En efecto Cantor lo utiliza en definiciones y demostraciones. Por ejemplo en la sección 4 del artículo de 1895 "Contribuciones a los fundamentos de la teoría de números transfinitos" Cantor define la operación exponenciación entre números naturales n^m, como el número de posible funciones (el llama a las funciones "cubiertas" del primer conjunto), entre un conjunto que contiene m elementos y otro que tiene n elementos. Incluso, en este artículo, Cantor llama función de x y denomina f(x) a lo que nosotros conocemos como imagen de x.

Gracias, Información recibida@@theaplusproject1

Your very welcome. Please feel free to ask any question related to this topics@@adrianmonk4468

Me alegra mucho que lo hayas encontrado útil.

Muchisimas gracias. Comentarios como este me invitan a seguir en esta labor.

Thanks for your question. I understand that your question is how to compute e^-5. Well e=2.7182818, approximately. So, one way to compute this will be using this approximation in your calculator and use minus 5 as the exponent. However, every Financial and Scientific calculator has a key for the exponential function (e^x) you can use this function of your calculator. If you want to know more about the number e, you can see my video: ua-cam.com/video/6ShLN8B8xDs/v-deo.html

You’re very welcome. Please let me know if you need to see the solution of other problem in a UA-cam video

Hi Alifia, Thanks for your words. Any time that we want to compute a probability of the form, P(X<=a) (with a less than or equal to), we need to inform Excel that this is a problem of cumulative probability. For doing that we can type in Excel, as final argument, "TRUE", or a 1, that has the same meaning in Excel. With this, we inform Excel that is true that this is a cumulative probability. If the problem is an exact probability, that is to say is of the form P(x=a), then we need to inform Excel that it is not cumulative typing as a final argument "FALSE" or a 0. If you have further questions, do not hesitate in asking us. Thanks again

Your really welcome Adrian :)

Hello MM-ys4fx, Could you provide more information about the context of your question. I will be very happy helping you and providing a video explaining. However, I will need more information. What is the topic? What do you mean when you say "crash multiple"? What is the subject you are studying?

@@theaplusproject1 I am not good at English but I am a moment that the responsibility is giving a number and predicting the result The Data Are 6.51 and 9.51 The Result Is = 33.88 The result is the number of prediction I want it because I discovered that one of the games are going on this pattern

@@MM-ys4fx I still want to help you. however I do not understand exactly what Is the actual question. If you want, you can write the whole question in your mother tongue ( if is taking from a book, type exactly as it is), and I will try to translate using a digital translator.

@@theaplusproject1 شكرا لك حقا انك انسان رائع ما اقصده اني العب لعبه اسمها الطيارة وهذه الطيارة تتحطم في ارقام مميزه وكأنها تستخدم معادلة معينة او خورازميه معينة ولذالك بحثت حتى حصلت على هذه المعادلة التي تستخدمها اللعبة

@@MM-ys4fx Great I like the problem, and I think I can help you to solve it. But Still I have some questions: The plane can crash in any real number, from minus infinite to infinite with the same probability? You told me that there are two data 6.51 and 9.51. What role do these two numbers play?

I am very glad that you found this video useful. Unfortunately, I do not tutor at this time. However, if you make a comment asking me a math question, I'll be happy to make a video of the answer and post it here in this channel.

e is approximately 2.7182818285. It is la base of natural logarithms. Every scientific calculator has a function to compute its powers, e^x. In this channel there is a video showing deduced to how this constant can be obtained here it is the link ua-cam.com/video/6ShLN8B8xDs/v-deo.html

Hi Yuyu, Thanks for your question. This problem is solved using the probability of the complement of an event P(A)=1-P(complement of A). When you ask P(x>3), 3 is not included, so you need to include it in the complement. In case of a discrete variable, as a poisson variable, to be more than 3 is actually to be or 4, or 5 or,6, etc. 3 is not included. Then if you are going to use the complement, this will take into account all the numbers that are not there: 0, 1, 2 and 3. For that reason you compute 1- P(x=<3) to include the 3 in the complement of the event

@@theaplusproject1 thank you Sir 🙏🏻

Hi Ibeth, Thanks a lot for your question. If you consider that is necessary, I will make a video in two days (Please let me know). Anyway, here is the answer to your question. In case you are not allowed to use Excel, you will need to have a t-distribution table in your hands. You won't be able to calculate exactly the p-value, but you will be able to have an estimation and take a decision. In this example, because there are 17 degrees of freedom, you should check the row of the table corresponding to 17 df. and notice that the t-value we obtain in this problem -1.768 is lower than -1.740 (in the table the values are positive) which is the value in that row and the column corresponding to two-tails 0.10. That means that the p-value is lower than 0.10 and you can reject the null hypothesis.

@@theaplusproject1 Thank you so much. If you do a video about that. Please tag me 🙏🏻

@@ibethdiaztapia1033 Hi Ibeth, I posted a solution of the same problem, now using a t-distribution table. the link of the video is this ua-cam.com/video/Saku8bXIMu4/v-deo.html.
