According to astronomers, what is a "light year"

Answers

Answer 1

Answer: A light year is the distance light travels in one year.

Let's figure out what this distance is shall we...?

We know that speed = distance / time, therefore distance = speed x time.

Speed of light = 299,792,458 m/s

Time (One year) = 31,536,000 s

That is a ridiculous:

9.454254955 x 10¹⁵ metres,

Which is approximately:

9,400 trillion metres.

Only "one light year" away... That's a hell of a distance.

Answer 2

Answer: Here's a hint : A light year is a distance, not a time.

A light year is a unit of length used informally to express astronomical distances.

What is the standard error of the proportion if 80% of the 1,200 respondents in a yes/no survey answered "no"?

Answers

standard error for a sample proportion, p = 0.8, n = 1200

$SE= \sqrt{ (p(1-p))/(1200) } = \sqrt{ (0.8(1-0.8))/(1200) } \approx 0.015 * 100\%=1.15\%$

Please solve, -8-2(7r+1)=-94

Answers

Answer:

r = 6

Step-by-step explanation:

Hello!

-8 - 2(7r + 1) = -94

Add 8 to both sides

-2(7r + 1) = -86

Divide both sides by -2

7r + 1 = 43

Subtract 1 from both sides

7r = 42

Divide both sides by 7

r = 6

Hope this Helps

-8-14r-2=-94
-10-14r=-94
-14r=-84
r=6
