Worked Solution & Example Answer:The graph shows some data about smoking tobacco in the UK - Edexcel - GCSE Biology - Question 1 - 2015 - Paper 1
Step 1
Calculate the decrease in the percentage of females who smoked tobacco from 1990 to 2010.
Answer
To find the decrease in the percentage of females who smoked tobacco, we first look at the graph to determine the percentages in 1990 and 2010. From the graph, the percentage of females who smoked tobacco in 1990 is approximately 36%, while in 2010 it is around 27%. Thus, the calculation is:
ext{Decrease} = ext{Percentage in 1990} - ext{Percentage in 2010} = 36 ext{%} - 27 ext{%} = 9 ext{%}.
Therefore, the decrease in the percentage of females who smoked tobacco from 1990 to 2010 is 9%.
Step 2
