In what ways is our confidence in our predictions often wrong? (AP Psychology)

It entails being out of touch with reality, where your optimism isn't grounded in comparison to the situation you're in.
For example, imagine climbing Mount Everest and you underestimate the weather, which are underestimating obstacles and risks.

Iam guessing it’s a metallic because it is powdery and so belongs to group 2it is also light. so i would guess it’s graphite.if available, additional information would be very for-example its color. if black it would be division e. also try to mark it on a paper.

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:
