Answer:
x=−22/13
Step-by-step explanation:
Let's solve your equation step-by-step.
2x−8(5+3x)=4(x+1)
For this case we have the following expression:
When multiplying to the power of 100 we have:
We have to:
0: Unit
0: Ten
9: Hundred
1: One thousand unit
2: Ten thousand

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.
