<h3>
Answer: D) 4</h3>
===========================================================
Explanation:
The width of the confidence interval is 20-12 = 8 units. That cuts in half to get 8/2 = 4 which is the margin of error.
The center of the confidence interval is (12+20)/2 = 32/2 = 16. Add four onto this to get 16+4 = 20, which is the right endpoint. Subtract four from the center to get 16-4 = 12, which is the left endpoint.
Effectively, it's like saying "an archer aims for the value 16 on the number line, and the arrow could land as high as 20 or as low as 12".

Answer:
The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.
Explanation:
For a cell reaction to be sponteanous, the standard cell potential must be positive.
<h3>What is a sponteanous cell reaction?</h3>
We define a cell reaction as sponteanous when the value of the standard cell potential is positive. If the standard cell potential is negative then the reaction is not sponteanous.
The question here is incompete but we know that the reactions that are sponteanous will all have a positive standard cell potential.

A long string can be easily stretched. The Two points on the string are labeled A and B is that A should be at 90 degrees with same magnitude and B should be at 270 degrees with same magnitude.
<h3>What is Angle magnitude</h3>
- This is known as the amount of rotation via which one of the arms is said to be rotated about vertex to result in a given position of the other.
Equal vectors are known to have the same magnitude and direction. Two vectors are said to be equal when their magnitude and direction are said to be same.

A long string is stretched and its left end is oscillated upward and downward. Two points on the string are labeled A and B.At the instant shown, orient v(A) and v(B) to correctly represent the direction of the wave velocity at points A and B.At each of the points A and B, rotate the given vector to indicate the direction of the wave velocity.Figure:A string is attached and moving up and down
