24. One explanation for why so many of us are addicted to our phones and social media is that It follows a partial reinforcement schedule.
deep down all human are narcissists,
the Premack principle suggests that rewards can be addicting
the continuous reinforcement schedule does not allow breaks in reinforcement
social learning is a powerful contributor to reward pathways in the brain

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
