a question about activaton function on my neural network project

I want to plement a model of neural network using sckitlearn . and I want to know which activation function should I use ? I have 10 input variable and one output . all variable are floats(positive ). and the Output is a pecentage ( 0 to 100).

and my model is note linear to the output variable, so i'll creat regression model with one hidden layer!!
