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.
Answer:
110,000 base 2
Step-by-step explanation:
column 1 [the first position in the number]:
1+1=0, (carry 1<u>)</u>
column 2:
0+1 +<u>1</u> <em>(carried)</em>=0, (carry 1)
column 3:
1+0+<u>1</u><em> (carried)</em>=0, (carry 1)
column 4:
0+1+1 <em>(carried)</em>=0, (carry 1)
column 5:
1+1+1=1, (carry 1)
then you write the last 1 'cause there is n number to add with:
In binary system the highest number to write is 1, if you add 1+1, it jumps to 0, and you have to carry 1 to the next position.
If you are not sure about the sum, you can convert the numbers in base 2, to base 10, so you can know if it is correct:
So 21+27=48.
<em>In decimal system when you add 9+1, it jumps to 0 and then you have to carry 1 to the next position, because the the highest number you can write is 9.</em>
Answer:
225
Step-by-step explanation:
A = 5. 3A = 3(5) cubed. So 3 times 5 is 15. 15 cubed is 225.
Answer:
Acute scalene triangle
Step-by-step explanation:
The triangle is acute because all of the angles are less than 90 degrees.
It is scalene because the 3 sides are all different lengths.
