Q
Q: In a study, it was found that 70% of patients with a certain disease are male. If there are 400 patients, how many are expected to be male? (2020)
Solution:
Expected male patients = 70% of 400 = 0.7 * 400 = 280.
Steps: 5
Show Steps
Step 1: Understand that 70% means 70 out of every 100 patients are male.
Step 2: Convert 70% into a decimal. 70% as a decimal is 0.7.
Step 3: Multiply the total number of patients (400) by the decimal (0.7).
Step 4: Calculate 0.7 * 400 to find the expected number of male patients.
Step 5: The result of the calculation is 280, which means 280 patients are expected to be male.
