Answer:
a) 256
b) 1/256
Step-by-step explanation:
_ _ _ _ _ _ _ _
every position has two possibilities (head or tail)
So,
2×2×2×2×2×2×2×2 = 2⁸ = 256
b) all tails is one of the 256 possible outcomes, so the probability is 1/256

Answer:
C) Neither
Step-by-step explanation:
These two equations are not parallel, because they don't have the same slope. And they're not perpendicular to each other either, because perpendicular lines have negative reciprocals of the slopes. Therefore, the answer is C) Neither.
Answer:
Coordinates of E is (-2,7)
Step-by-step explanation:
Midpoint = ((x1+x2)/2,(y1+y2)/2)
xK = (xW + xE)/2 => xE = 2xK - xW = 2(0) - 2 = -2
yK = (yW + yE)/2 => yE = 2yK - yW = 2(3) - (-1) = 7
