If A is the center of the circle, then which statement explains how segment ED is related to segment FD? Circle A with inscribed

Sveta_85 [38]

Answer:

The correct option is;

Segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A

Step-by-step explanation:

All chords perpendicular to the radius of a circle are bisected by the radius of the circle

Given that DA can be extended to the circumference of circle A to form a radius of the circle A, and that DA is perpendicular to EF, therefore, DA bisects EF or EF is bisected into two equal parts by DA such that segment ED is congruent to segment FD

Therefore, the correct option is that segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A.

More than three-quarters of the nation’s colleges and universities now offer online classes, and about 23% of college graduates

RUDIKE [14]

Answer:

0.1997 or 19.97%

Step-by-step explanation:

Have taken course online (H) = 23%

Have NOT taken course online (N) = 77%

Have taken course online and don't believe they provide same value (H&D) = 61%

Have NOT taken course online and don't believe they provide same value (N&D) = 73%

The probability that a student has taken a course online given that she does not believe that online courses provide the same educational value as one taken in person is;

$P(H|D)=\frac{P(H)*P(H\&D)}{P(H)*P(H\&D)+P(N)*P(N\&D)}\\P(H|D)=\frac{0.23*0.61}{0.23*0.61+0.77*0.73}\\P(H|D)=0.1997$
