What is the solution to the equation 4|x| − 8 = -8? A.
x = -4 or x = 4
B.
x = 0
C.
x = -16
D.
No solutions exist.

4x - 8 = -8

or, 4x = -8 + 8

or, 4x = 0

or, x = 0/4 = 0

The answer is option B. 0

option b. 4.9%

Explanation:

1) The probability that a dart thrown at random within the dart board will hit the bull's eye is equal to the ratio of the areas:

probability = area of the bull's eye / aera of the dart board.

2) Area of the dart board = π × (radius)² = π × (18 in)²

3) Area of the bull's eye = π × (radius)² = π × (4 in)²

4) So, the probaility is:

  π (4 in)²           4²
= = 0.0494
 π (18 in)²         18²

5) The percent probability is that number times 100: 0.0494 × 100 = 4.94%
