Approximately what percentage of population health is due to health behaviors? (a) 5 percent

The correct answer is about 30 percent.  

Health behaviors are affected by the cultural, social, and physical surroundings in which an individual work and live. They are structured by external constraints and individual choices. The positive behavior encourages health and inhibits disease, while the reverse is true for risk behaviors.  

Environmental exposure, social circumstances, and health care are the other prime determinants of health, holding for about 70% of the population health.

The answer to your question is 2, 1/2, 1, 2

Step-by-step explanation:

a) 3² 4³ 2⁻¹ / (3 4)² = (3²)(4²) 4 (2⁻¹) / (3 4)² = (3  4)² 2² 2⁻¹ / (3  4)² = 2

b) 2⁴ 3⁵ / (2 3)⁵ = 2⁴ 3⁴ 3 / (2 3)⁵ = (2 3)⁴ 3 / (2 3)⁵ = 3 / 2 3 = 1/2

c) 3⁻³ 2⁻³ 6³ / (4°)² = (3 2)⁻³ 6³ / 1² = 6⁻³ 6³ = 1

d) (3 2)⁴ 3⁻³ / 2³3 = 3⁴2⁴ 3⁻³ / 2³3 = 3 2 / 3 = 2
