Answer: The number of people can be expected to have cold = 34
Step-by-step explanation:
Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.
If a doctor sees 40 patients, then the number of people can be expected to have cold = [tex]40\times\dfrac{6}{1+6}[/tex]
[tex]=40\times\dfrac6{7}[/tex]
[tex]=\dfrac{240}{7}\\\\=34.29\approx34[/tex]
Hence, the number of people can be expected to have cold = 34
