Answer:
A good maximum sample size is usually 10% as long as it does not exceed 1000. A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a population of 200,000, 10% would be 20,000.
Step-by-step explanation:
Looks like an arithmetic sequence where
a =4 and d = 5
term(n) = a + (n-1)d = 4 + (n-1)(5) = 4 + 5n - 5 = 5n -1
term(100) = 5(100) - 1
To find the diameter, find the circumference, i.e the length covered in one revolution, and then subject the diameter from formulas.
Circumference = 3.6 ÷ 18 = 0.2m = 2πr
πr = 0.2 ÷ 2 = 0.1
r = 0.1 ÷ (22/7) = (0.1 * 7) ÷ 22 = 0.7 ÷ 22
r = 0.0318
Diameter = 2r
Diameter = 2 * 0.0318 = 0.0636m ...//Ans ...
