Answer:
-20
Step-by-step explanation:
i used a calculator.
Answer:
The answer is 3x+2
Step-by-step explanation:
2(3x-1)-3x+4
I did distributive property on 2(3x-1) how I did that was I multiplied 2 times 3x which is 6x (2 times 3x=6x). Then I multiplied 2 times -1 which equals -2 (2 times -1=-2).
new expression:
6x-2-3x+4
I combined all the numbers with the variables (6x and -3x) and by subtracting both of them you get 3x (6x-3x=3x). After that you combine -2 and 4 which equals 2 (-2+4=2).
This is now the final expression (your answer):
3x+2

It is the systematic random sampling
Step-by-step explanation:
I found this definition online on a khan academy website that will prove that the systematic random sampling is correct:
"Systematic random sample: Members of the population are put in some order. A starting point is selected at random, and every n^th member is selected to be in the sample."
Hope this helps!
