Your answer would be a = 74°

Due to the Corresponding Angles Postulate, angle RMN is congruent to angle a. So, I added 34 + 40 to get the value of angle RMN, which is 74.

Hope this helps!

Troyanec [42]

Answer:

0.29

Step-by-step explanation:

z-score is given by the formula:

z=(μ-M)/σ where

  • μ is the hypothesis drive distance, which is 222
  • M is the mean sample drive distance
  • σ is the standard deviation of the sample drive distance

Therefore

z=(222-218)/14≈0.29

What defines a circle?
frez [133]

The answer is choice D. All coplanar points equidistant from a given point.

In other words, all points that arethe same distance away from a fixed point. For example, if you have some fence post and you are 2 feet away from the fencepost, then that marks one point on the circle. Then move to another point that is also 2 feet away from the fencepost. Repeat until you have a bunch of points. All of these points will form a circle. The term "coplanar" means "all in the same plane". A plane is a flat surface like a flat piece of paper that doesn't bend or curve.
