21 and -4, because -4x21 = -84, and 21+-4 (– 4) = 17
First off, your chances of red are not really 50-50. You are overlooking the 0 slot or the 00 slot which are green. So, chances of red are 18 in 37 (0 slot) or 38 (0 and 00 slots). With a betting machine, the odds does not change no trouble what has occurred before. Think through the simplest circumstance, a coin toss. If I toss heads 10 times one after the other, the chances of tails about to happen on the next toss are still on a 50-50. A betting machine has no ability, no plan, and no past.
Chances (0 slot) that you success on red are 18 out of 37 (18 red slots), but likelihoods of losing are 19 out of 37 (18 black plus 0). For the wheel with both a 0 and 0-0 slot, the odds are poorer. You chances of red are 18 out of 38 (18 red slots win), and down are 20 out of 38 (18 black plus 0 and 00). It does not really matter on how long you play there, the probabilities would always continue the same on every spin. The lengthier you play, the more thoroughly you will tie the chances with a total net loss of that portion of a percent in accord of the house. 18 winning red slots and either 19 or 20 losing slots.
The annual interest rate of her investment would be = 4%
<h3>Calculation of annual interest rate</h3>
The principal amount invested= $500
The period of investment= 4years
The interest received= $80
The interest rate= ?
To calculate the interest rate use the formula,
SI = P×T×R/100
80 = 500 × 4 ×R/100
Make R the subject of formula,
R= 80 ×100/500×4
R= 8000/2000
R= 4%
Therefore, the annual interest rate of her investment would be = 4%.

1. And the meeting house windows, blank and bare, / Gaze at him with a spectral glare.
This is a <em>couplet</em>. You can tell this because there are two lines, a couple, as indicated by the slash between the phrases, as well as the end words rhyming.
2. A glimmer, and then a gleam of light / He springs to the saddle, the bridle he turns / But lingers and gazes, till full on his sight / A second lamp in the belfry burns.
This excerpt, I believe, is meant to highlight the <em>end rhymes</em>. You see, in the first and third lines, the last words rhyme, and the second and fourth lines' last words rhyme.
3. ...the Mystic meeting...
Seeing as how this is so incredibly short, and both "mystic" and "meeting" start with an "m", it is safe to assume that this is meant to highlight an <em>alliteration</em>. An alliteration is when two or more words in a row start with the same letter. A famous alliteration is in the tongue twister, "she sells seashells by the sea shore."
4. ...like a sentinel's thread / The watchful night wind...
This is a <em>simile</em>. Both similes and metaphors compare one thing to something generally more abstract in order to describe it better. In order to tell if something is a simile or a metaphor is to look for the words "like" or "as," because those are used in similes, but not metaphors. Since this uses the word "like," it is safe to assume that this is a simile.
