Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2

Answer:
Sampling bias. Remedy is to use Systematic Random Sampling techniques
Step-by-step explanation:
It is a sampling bias because it denies the other party the opportunity to respond to same question to determine their opinions
The possible remedy to this study is to adopt the systematic random sampling approach to make provision for other party to also respond to same question before an inference or conclusion is reached.
Because all you do is times that number by itself then when you divide you have to take half of the number then divide it
