Worked Solution & Example Answer:In the UK in 2016, there were 525 048 deaths - AQA - A-Level Biology - Question 5 - 2020 - Paper 1
Step 1
Calculate total cancer deaths
Answer
To find the total number of cancer deaths, we calculate:
Total cancer deaths = Total deaths × Percentage of deaths from cancer\nTotal cancer deaths = 525,048 × 0.304 = 159,825.792
Rounding to the nearest whole number, there are approximately 159,826 cancer deaths.
Step 2
Calculate throat cancer deaths
Answer
Next, we find the number of deaths from throat cancer by calculating:
Throat cancer deaths = Total cancer deaths × Percentage of deaths from throat cancer\nThroat cancer deaths = 159,826 × 0.05 = 7,991.3
Rounding to the nearest whole number, there are approximately 7,991 deaths from throat cancer.
Step 3
Calculate mean monthly throat cancer deaths
Answer
Finally, we find the mean number of throat cancer deaths per month by dividing the total throat cancer deaths by 12 (months):
Mean monthly throat cancer deaths = Throat cancer deaths / 12\nMean monthly throat cancer deaths = 7,991 / 12 ≈ 666 (rounded to the nearest whole number).
Therefore, the mean number of people who died of throat cancer per month in 2016 is approximately 666.
