Ian is bisecting line segment CD. First, Ian places the compass on point D and opens it to a width larger than half of the segme
1 answer:
The next step that should be taken by Ian to bisect segment CD is: A. swing arcs on both sides to intersect the first two arcs created.
<h3>What is a line segment?</h3>A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length (numerical value).
In Geometry, a line segment can be measured by using the following measuring instruments:
- A scale (ruler).
- A divider.
- A compass.
In Geometry, an arc can be defined as a trajectory that is generally formed when the distance from a given point has a fixed length (numerical value).
Based on the information provided, the next step that should be taken by Ian to bisect segment CD is swinging arcs on both sides to intersect the first two arcs created.

<u>Complete Question:</u>
Ian is bisecting segment CD. First, Ian places the compass on point D, opens it to a width larger than half of the segment, and swings an arc on both sides of segment CD. Then, Ian keeps the compass the same width and places it on the other point C. What is the next step?
Swing arcs on both sides to intersect the first two arcs created.
Swing an arc that intersects the segment.
Swing arcs that intersect a point that is not on the segment.
Swing an arc that intersects the opposite endpoint.

Answer:And we can find this probability with this difference:
And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.
So then the best answer would be 21.82 %
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the time it takes to trim a tree of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:And we can find this probability with this difference:
And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.
So then the best answer would be 21.82 %
