The price of binders and paper decreases: would the price decrease or increase and would the quantity decrease or increase. also what would be the determinant (tribe) or (rotten)?

price: decrease ( ) or increase ( )

quantity: decrease ( ) or increase ( )

determinant: demand (tribe) or supply (rotten)

The decrease of what? The way you worded the question makes absolutely no sense to me.

The bystander effect  for some reason my history teacher was talking about this 

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:
