Answer 1

Answer: The average percentage change per year was 0.3652%.

Step-by-step explanation:

Given: In 1992, 18.6% of the world population was undernourished.

In 2015, 10.9% of the population was undernourished.

The  average percentage change per year will be

$\dfrac{\text{Percentage in 2015- Percentage in 1992}}{201-1992}\\\\=\dfrac{18.6\%-10.9\%}{2015-1992}\\\\=\dfrac{8.4\%}{23}\approx0.3652\%$

Hence, the average percentage change per year was 0.3652%.
