Answer:
D. The equation has a variable multiplied by itself. A squared variable.
Step-by-step explanation:
A quadratic equation will always start with a term being squared. For example, 
+ 5x + 7 = 44. Another example would be 
+ 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!

Answer:
Throw this sample out and start over again with a better sampling method
Step-by-step explanation:
Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.
Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.
Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
Answer:
2 pounds
if you add .5 4 times with each other, you get 2
Step-by-step explanation:
Notice that
9y² - 4xy + 4x²/9 = (3y - 2x/3)².
Therefore (9y² - 4xy + 4x²/9) / (3y - 2x/3)
= (3y - 2x/3).
