Hope this helps!
Answer:
A
Step-by-step explanation:
The distance from the centre to a point on the circle is the radius.
Calculate radius r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, - 2)
r = 
= 
=
= 8 → A
Answer:
(B) An uncontrolled experiment.
Step-by-step explanation:
In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled
Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the cholesterol level is decreased after particular time period,
Hence, it is an uncontrolled experiment.
Thus, option B is correct.
Answer:
Option C
Step-by-step explanation:
From the graph attached,
Slope of the line passing through two points A and B will be,
m = 
= 
= 
Triangles having same ratio of Height and base (slope) will lie on the line graphed.
Option A
Slope pf the triangle = 
Slope of the line ≠ Slope of the triangle
Therefore, triangle will not lie on the line.
Option B
Slope of the triangle = 

Triangle will not lie on the line.
Option C
Slope of the triangle = 
Since, slope of the line = slope of the triangle
Triangle will lie on the line.
Option D
Slope of the triangle = 
But 
Therefore, triangle will not lie on the given line.
