Answer 1

for every person who actually has the flu, there are 6 people who have flu-like symptoms resulting from a cold.if a doctor sees 40 patients, determine how many of these you would expect to have a cold

According to this information, When a doctor sees a person with the flu, he sees 6 other patients that do not have the flu. The doctor has seen a total of 7 patients. so you can set this up as a proportion.

(Patients with a cold) / (Total patients seen) 6/7 = x/40 Take cross products

7 x = 6 (40)

7 x = 240

x = 34 2/7 Since there can'tbe a fraction of a person.

We will round the answer to the nearest whole person
