Answer:
Step-by-step explanation:
Because x=5y-4 you can substitute 5y-4 into the x in the other equation. This makes 5(5y-4) + 4y = 38. When simplified it gives 25y -20 +4y = 38. Move like terms to each side to get 29y = 58 and get y=2. Then you can substitute 2 into the y in either equation to find x. I will do x=5(2)-4 to get x=6. So x=6 and y=2
Answer:
x=9
Step-by-step explanation:
2x=x+9
Subtract x from both sides;
2x-x=x+9-x
Simplify;
x=9

Answer:
The true statements about the sample described in the scenario above are:
The sample should be larger to give more reliable information.
The sample size is too small to represent the population.
The sample size is too small and can lead to false inferences.
Step-by-step explanation:
The sampling technique employed is a systematic random sampling where samples are chosen at every specified interval. Hence, the sample is randomly selected.
