Found a similar question on the Internet. Their answer is - The light that a star actually gives off is the apparent magnitude. Upon further research, apparent magnitude term is used by astronomers to describe how bright a star is or any celestial object as seen by an observer on Earth. There's also what they call as absolute magnitude. It represents how bright a star would look like if it were 10 parsecs or 3.26 light years<span> </span>away from the Earth.

The standard deviation of the data set is D. ABOUT 13.4

14, 34, 23, 50, 25, 16, 48

Arrange in ascending order: 14, 16, 23, 25, 34, 48, 50

mean = (14 + 16 + 23 + 25 + 34 + 48 + 50) / 7 = 210/7 = 30

|14 - 30| = 16 ⇒ 16² = 256
|16 - 30| = 14 ⇒ 14² = 196
|23 - 30| = 7 ⇒ 7² = 49
|25 - 30| = 5 ⇒ 5² = 25
|34 - 30| = 4 ⇒ 4² = 16
|48 - 30| = 18 ⇒ 18² = 324
|50 - 30| = 20 ⇒ 20² = 400

(256 + 196 + 49 + 25 + 16 + 324 + 400) / 7 = 1,266/7 = 180.85  variance
√180.85 = 13.45 standard deviation.

Guess my rule......<br>​
aniked [119]

Answer:

The rule in what is shown to be a graph and a in-out machine is:

y = 2x + 5

Step-by-step explanation:

2(5) + 5 = 15

10 + 5 = 15

15 = 15

TRUE RULE

2(7) + 5 = 19

14 + 5 = 19

19 = 19

TRUE RULE

2(8) + 5 = 21

16 + 5 = 21

21 = 21

TRUE RULE

y = 2x + 5 is your rule!
