Option B
Step-by-step explanation:
Although the difference is quite small (72 seconds—or just over a minute), the effect was statistically significant (P-value < 0.0001).

Answer:
x = 5
Step-by-step explanation:
-3(4x-8) = -36
Divide each side by -3
-3/-3(4x-8) = -36 /-3
4x-8 = 12
Add 8 to each side
4x-8+8 = 12+8
4x = 20
Divide each side by 4
4x/4 = 20/4
x = 5
