Systematic sampling refers to a method of random sampling during which sample members are extracted from a larger population and then collecting corresponding observations using a constant interval between samples taken. This interval, called the sampling interval, is measured by deducting the size of the population by the required sample size. As per the question, the store manager asks every 25th person about the sales which is a classic example of systematic sampling.
Answer: 1/3
Step-by-step explanation:
If RY + YC = RC
7x+4=10x-2
3x=6
x=2
18+18=36=RC
The value of RC is 36
Answer:
OPTION 1
Step-by-step explanation:
You just basically plug in x and y values in all the equations and check if you get the same answer each time.
Option 1 is correct because when you plug in let's say the first coordinates,10 and 4 it does give you 6 which is right.
Or you can test it the other way, just plugging in x values and see if you get the right y value for it shown above in the table.
Hope this helps!
59 is a prime number, so no two intergers can multiply together to make it.
