Answer:
2x - 3y
Step-by-step explanation:
-1/4(-8x+12y) = 2x - 3y
1000 + 500 + 250 + 125 + 62.5 = 1,937.5

Answer:
1. Even
Step-by-step explanation:
A function is even when it is symmetric over the y-axis. In this case, we have a parabola that has its vertex at (0,10), this means that it is indeed symmetric over they y-axis, so it is even.

which follows from the definition for expected value,

where

is the probability density function for
