Answer:
D. Systematic sampling
Step-by-step explanation:
- Systematic sampling is a type of probability sampling method in which sample members of a large population are selected according to a random starting position and a constant, periodic interval.
- This interval, called the sample interval, is calculated by dividing the population size by the desired sample size.
- so correct option is D. Systematic sampling .
The line that has the steeper slope is line b
Answer:
B divides A and B in the ratio of 1:2 internally.
Use this formula :
B (X,Y)=(m1x2+m2x1/m1+m2,m1y2+m2y1/m1+m2)
9 : 2 = 18 : 4
As: 9 x 2 : 2 x 2 = 18 : 4
--------------------
36 : 8 = 18 : 4
As: 18 x 2 : 4 x 2 = 36 : 8
--------------------
72 : 16 = 18 : 4
As: 18 x 4 : 4 x 4 = 72 : 16
