The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
m = (y2-y1) / (x2-x1)
Substituting the values we have:
m = (76-70) / (28-30)
m = -3
answer:
the slope of the line between points a and b is
m = -3
8 caps => 4 balls
6 caps => (6 x 4)/8 = 24/8 = 3 balls.
Answer:
This is an example of placebo testing.
Step-by-step explanation:
This is an example of placebo testing in which, the two groups are given two substances that are said to have an effect on the condition that is being treated but one of them is the actual medicine that is being tested while the other one has no real effect over the medical condition. But the volunteers are not given information on which of the medicines is real and which is not, so that this does not affect the outcome of the experiment.
I hope this answer helps.
