The strategy is following
Smaller number subtract from the greater. Result is distance between two numbers
For example you have 3 and 8
8-3-5
5 is the distance between 3 and 8
It also works with the negative numbers, for example 3 and -5
3-(-5)=8
Answer:
Rhion did better in maths test.

Given that:
Rhion scored 14 out of 17.
We will find percentage and then compare them.
Percentage = 
Percentage = 
Percentage = 82.35%
Rhion scored 31 out of 39.
Percentage =

Answer:
2
Step-by-step explanation:
A parallelogram is 4 sided figure. Since it is a irregular, the sides and angles must be in different measures.
When we rotating the irregular parallelograms about the midpoint of its diagonal, it will coincide with its pre-image at 180 degrees and 360 degrees.
Therefore, the answer is 2.
Answer:
Sampling interval = 9.323
Step-by-step explanation:
Given that:
Population size, N = 9500
Require sample, n = 1019
Sampling interval :
Population size / required sample size
Sampling interval = 9500 / 1019 = 9.3228
Interpretation :
In other to obtain a sample of 1019 drawn systematically from the population, a sample will be drawn at every 9.323 units from the population of 9500
