Answer:
Total área: 9+9+8+6= 32 mm^2
Step-by-step explanation:
Square = 3x3 = 9mm^2
Triangle= Heigh: sqrt (3^2+3^2) = 9 and base=3
A = (9x3)/2 = 9mm^2
Rectangle= 4x2= 8mm^2
Triangle (high: 5-2=3)
(4x3)/2 = 6mm^2
Total area
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define systemmatic sampling
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size
STEP 2: Determine the answer
The option that follows the systematic sample of workers is the last option because it follows a fixed, periodic interval of "every 4th worker until 80 workers are selected".
Hence, the answer is:
The consultant takes a list of the workers and selects every 4th worker until 80 workers are selected.
