A set of data has a mean of 12 and a standard deviation of 3. A data point of the set has a z-score of 1.3. What does a z-score of 1.3 mean?
The data point is 1.3 standard deviations away from 3
The data point is 1.3 standard deviations away from 12.
The data point is 3 standard deviations away from 1.3.
The data point is 3 standard deviations away from 12.
its B
A metallic wire carrying current is not charged - it is electrically neutral.
This is because a wire, or any type of conductor, cannot store charge - the fact that it is carrying current means that charge carriers that already existed in the wire are in motion. There are as many electrons as there are protons in the wire, which makes it neutral - there is no buildup of charge.
Answer:
299,792 kilometers
