Hi there!
Let's solve this inequality step by step!

First collect the terms on the left.

In order to solve, we must isolate r. Therefore we need to bring them all to the left. Our next step will therefore be to add 3r to both sides of the equation.

Finally we need to divide both sides of the equation by -1. Because we divide by a negative, the sign flips.

Hence, the answer is r < -3.

Answer:
it is 4

The answer or value to this question will be D
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.
288 divided by 12 = 24
240 divided by 10 = 24
