Jordan wants to estimate the number of students in his school who have their own cell phone. He surveys every eighth person who enters the cafeteria for lunch. Is this sample biased or unbiased. Explain.

Step-by-step explanation:

I wouldn't consider it biased, but I'll bet a stats person would. Their reason would be that those who enter the cafeteria are select segment of a school population.

Those are just four exceptions. There must be others -- like a staggered lunch period.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

i can't solve unless i know what the line is
