A survey indicated that 3 out of 5 doctors use brand X aspirin.
If 2000 doctors were surveyed, how many used brand X?
can somebody tell me is this the right answer yes or no,
2000/ 3/5 400*5/3*5
400/3 133 1/3
No.
You can't have 1/3 of a doctor.
3/5 = x/2000
Cross multiply and solve for x.
i still dont get it
To find out how many doctors used brand X aspirin out of the 2000 surveyed, we need to multiply the total number of doctors by the proportion who use brand X.
First, let's calculate the proportion of doctors who use brand X aspirin: 3 out of 5 doctors.
Proportion = 3/5
Next, multiply the proportion by the total number of doctors surveyed:
2000 * (3/5)
To simplify this multiplication, we can rewrite 3/5 as 3/5 * 1/1:
2000 * (3/5 * 1/1)
Multiplying the numerators and denominators, we get:
2000 * 3/5 = 6000/5 = 1200
Therefore, the correct answer is 1200 doctors out of 2000 used brand X aspirin.
No, that is not the right answer. To calculate how many doctors used brand X aspirin based on the survey results, you can use the following steps:
1. Identify the number of doctors who participated in the survey: In this case, it's given that 2000 doctors were surveyed.
2. Calculate the ratio of doctors who use brand X aspirin: The survey indicated that 3 out of 5 doctors use brand X aspirin. This can be written as a fraction: 3/5.
3. Multiply the ratio by the total number of doctors surveyed: To find how many doctors used brand X aspirin, multiply the ratio (3/5) by the total number of doctors surveyed (2000).
Let's calculate it step by step:
Step 1: Total doctors surveyed = 2000
Step 2: Ratio of doctors using brand X aspirin = 3/5
Step 3: Calculation - Multiply the ratio by the total number of doctors surveyed:
(3/5) * 2000 = (3 * 2000) / 5 = 6000 / 5 = 1200
Therefore, based on the survey results, 1200 doctors used brand X aspirin out of the 2000 doctors surveyed.
