1 answer

(a) To calculate the percentage increase in population from 1950 to 2014:

Percentage Increase = ((2014 population - 1950 population) / 1950 population) * 100
Percentage Increase = ((7,087,000 - 4,714,900) / 4,714,900) * 100
Percentage Increase = 2,372,100 / 4,714,900 * 100
Percentage Increase = 0.5025 * 100
Percentage Increase = 50.25%

Therefore, the population of Switzerland increased by 50.25% from 1950 to 2014.

(b)
(i) The 1950 population correct to 3 significant figures is 4.71 million.

(ii) The 2014 population in standard form is 7.087 x 10^6.
