Answer:
45 feet
Step-by-step explanation:
4 and 1/2 inches
1/2=5 feet
put the mixed number into an improper fraction
9/2 *5= 9*5= 45 feet
So, to find the answer you'd first add up how many patients you have:
20+50+100 = 170.
In a fraction your total would go on the bottom. Then you'd take how many patients are taking a real drug, which is represented by 20+50 = 70. This number would go on top.
So, the probability of a patient NOT getting a placebo is 70/170. Simplified would be 7/17.
The answer is D. 7/17.
