Answer:
y=-2x+7
Step-by-step explanation:
![Slope=m=\frac{1-(-7)}{3-7}=-2\\Since,y=mx+c\\y=-2x+c](https://tex.z-dn.net/?f=%20Slope%3Dm%3D%5Cfrac%7B1-%28-7%29%7D%7B3-7%7D%3D-2%5C%5C%3C%2Fp%3E%3Cp%3ESince%2C%3C%2Fp%3E%3Cp%3Ey%3Dmx%2Bc%5C%5C%3C%2Fp%3E%3Cp%3Ey%3D-2x%2Bc)
To find "c" put one of the points in the equation. Put$(3,1)$
$1=-2(3)+c$
$c=1+6=7$
Answer:
i) Assigning women at random ensures that the two groups are comparable.
iv) A control group provides a baseline for comparisons to determine treatment effects.
Step-by-step explanation:
(a)
It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.
(b)
A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.
