Answer:

A) True

Step-by-step explanation:

In an experiment that has the purpose of testing the efficacy of a procedure or drug, comparison is made against the efficacy of a placebo, a procedure or drug that is <em>intended to have no effect whatever</em>.

Famously, a placebo is often found to be nearly as effective (or even more effective) than the procedure or drug on trial. This effect is known as "the placebo effect."

The points (0, −4) and (3, 2) lie on the graph of a linear function. What is the rate of change of the function? Enter

docker41 [41]

I don't entirely know what you mean by 'rate of change', but I'll assume that you mean slope.

0, -4 and 3, 2 are on the coordinate plane.

From 0, we go over three to reach 3.
From -4, we go up six to reach 2.

Since slope is in essence, rise/run, we have the following fraction:

6/3, which can be re-written as 2/1 or just 2.

Hope this helps!
