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.
this is your answer, i hope this helps you
Answer:
96 sq. m
Step-by-step explanation:
If the width is x, the length is x + 4 and since perimeter = 2 * (length + width), we can write:
40 = 2(x + x + 4)
40 = 2(2x + 4)
20 = 2x + 4
16 = 2x
x = 8 so x + 4 = 12, therefore the area is 8 * 12 = 96 square meters.
