Postsecondary • 2yr.Dans la région 1, le pourcentage des gens en faveur de la vaccination est de 70% tandis que la région 2, le pourcentage des gens en faveur de la vaccination est de 60%. La population de la région 1 est 4 fois plus nombreuse que celle de la région 2. Est-ce que le fait d’être en faveur de la vaccination est indépendant de la région? Justifier votre réponse dans la plage de réponse.
Je sais que pour que les variables soient indépendantes, il faut que P(AnB)=P(A)*P(B) et P(AnB) est l'intersection entre P(A) et P(B).
Mais je ne comprends pas comment il pourrait y avoir une intersection entre le fait d'être en faveur de la vaccination et le fait de venir d'une région soit 1 ou 2. Merci

Postsecondary • 2yr.Hello!
I sent a question a few minutes ago and received an answer. However, because I cannot respond back on the same post, I am putting the answer here since I still need a bit of help :)
The spring scale reads the measures in Newtons, so I know I can find the force with that. However, I am not sure how to do the procedure experimentally more specifically. I was thinking I could pull the person in the cart with a constant force for a certain distance and a certain amount of time to find it's constant velocity. Then I could release the person and measure the distance and time taken to stop, so the constant velocity calculated earlier would be my Vinitial and Vfinal=0. Finally, with that data, I could manipulate the equations to find the unknown. Does that sound right?
Also, would the acceleration calculated from the kinematic equations be same one that is used in F=ma and the force with which I pulled the person is F. So the only thing missing would be m, right?
Thanks!!

Postsecondary • 2yr.Hello!
I have a lab that involves Newton's law. Basically, one person has to sit on a moving cart and we are required to find the weight of the person and the cart together experimentally. We cannot weight them. However, we have a rope, a spring scale, a timer and tape measure. I am not sure exactly how to proceed. We can use newton's second law (F= ma) to find the acceleration and we can also use the kinematic equations. Can you please help me with the procedure? What steps should I do?
Thank you!
