Common Tangents
You have studied the properties and theorems of circles related to radii, chords,
secants, and tangents. These components help to create angles and segments inside
and outside a circle. However, there are also properties and components associated
with two circles together. All circles are similar to each other and all circles are
congruent when their radii have the same length. For this project, let's consider the
intersection of two circles. There are three possible arrangements.
1. No points of intersection:
АВ ВА
2. One point of intersection:
BAC. ACB
3. Two points of intersection:
D A. C. B

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
