Answer: This study uses a control group, this study uses repeated measures design, and this study uses random sampling
Step-by-step explanation:
Whole number- is zero and positive integers and Natural numbers- are counting numbers example (1,2,3,4.....) natural numbers do not contain 0
Answer:
No solution.
Step-by-step explanation:
2x + y = 7
-2x - y = 6
From the first equation:
y = 7 - 2x
Plug this into the second equation:
-2x - (7 - 2x) = 6
-2x + 2x = 6 + 7
0 = 13
this doesn't make sense so theer is:
No solution.
