What are the relationships among radii, chords, tangents, and inscribed and circumscribed angles?

2 answers:

6 0

These are all parts of circles.

A radius is the distance from the center of a circle to the edge.

A chord is a line segment from 2 different places on a circle.

A tangent is a line that touches the edge of a circle in only 1 place.

Inscribed angles are inside a circle and circumscribed angles are on the outside of a circle.

Step-by-step explanation:

Radii : Radii is the plural of radius. A radius is the distance measured from the the center of the circle to one side of the circle touching the circumference of the circle.

Chords : A chord is any straight line segment touching any two points on the circumference of the circle.

Tangents : A tangent is a straight line passing through a point at the circumference of the circle . Tangent is always at right angle to the radius at that point. It passes through only one point at the circumference.

Inscribed angles : Inside a circle when two chords meet at a point, they make an angle called as the Inscribed angle. An inscribed angle is always formed inside the circle.

Circumscribed angle : A circumscribed circle is formed when two tangents of a circle intersect s at a point. A circumscribed angle is always formed outside the circle.

Answer:

-Convenience Sampling

Step-by-step explanation:

Convenience Sampling is a sampling method that is employed simply because the samples are easy to reach or access. It is a non-probability system of sampling and not a very strong method of sampling. For a serious research such as the one being conducted by the Superintendent, who has ample time to perform the research, this is not a very good sampling method. A Convenience style of research would mean that he can just walk into a cafeteria with students and administer the test to them.

Since he has detailed information of the students, he should choose any of the other mentioned sampling techniques in the options provided to randomly select the subjects. This would help to prevent bias, and enable him to make generalizations with the result of the research.

yan [13]

Answer:

There are 2,598,960 ways to receive 5 cards from a deck of 52.

Step-by-step explanation:

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

a. How many ways are there to receive 5 cards from a deck of 52?

$C_{52,5} = \frac{52!}{5!(47)!} = 2598960$

There are 2,598,960 ways to receive 5 cards from a deck of 52.

IRINA_888 [86]

Answer:

$52$ roses and $117$ sunflowers

Step-by-step explanation:

Since the ratio of roses to sunflowers is $4:9$ , we can represent how many there are of each as $4x$ and $9x$ , respectively. We know that there are $65$ more sunflowers than roses, so we can set up the following equation to solve for $x$ :
