<span>Diamond is an evolutionary biologist, interested in adaptations, and he proceeds to speculate that New Guineans exhibit these heightened-mental-activity traits in response to their environment, which presents them with constant and varied challenges. He gets away with it because (1) this statement is buried inside his main thesis, which is in accord with the fundamental dogma (Western superiority is just an accident of geography), and (2) his superior racial group is non-white, and it's okay to call whites inferior</span>
Answer:
Explanation:
Part D
For d, the very first thing you need to do is figure out which one of the steps you are going to use. You have 2 in b^2 + 2, so even if b = 0 the two still matters. It means that you use f(x) = -x + 3 because that's what you use when you have 2 or above.
The second thing you have to realize is that f(x) = -x + 3 has the meaning of what ever you see on the left in the place of x, you put on the right wherever there is an x.
In this case f(b^2 + 2) = -b^2 - 2 + 3 = 1 - b^2
I'm not sure enough to give you an answer for the domain and range, not this time of night.

Answer: 93
Explanation:
Firstly, we need to know the rural.scire for the 4 tests. Since the mean for the 4 tests is a 92, the total score will be:
= 4 × 92
= 368
Since we want to know the score for he 4th test, we add the score for the 3 tests that she remembers and subtract from 368. This will be:
= 368 - (100 + 95 + 80)
= 368 - 275
= 93
She had 93 in her last test.
