All cases rewritten in the form of <em>difference</em> expressions are listed below:

  1. <em>x - 1/2 = 0</em>, <em>x + 1/3 = 0</em>
  2. <em>x + 3 = 0</em>
  3. <em>x - 5 ≤ 0</em>
  4. <em>x + 1/3 ≥ 0</em>
<h3 /><h3>How to translate equalities and inequalities into difference expressions</h3>

Equalities represent relationships between two expressions, in which one expression is equal to another. An equality (<em>x = a</em>) is equivalent to the following <em>difference</em> expression:  

<em>x - a = 0</em>   (1)

And inequalities represent relationships between two expressions, in which one expression is not necessarily to another. An inequality (<em>x < a, x > a, x ≤ a, x ≥ a</em>) is represented by the following <em>difference</em> expression:

<em>x - a = b</em>   (2)

Where b have the following cases:

  1. If <em>x < a</em>, then <em>b < 0</em>.
  2. If <em>x > a</em>, then <em>b > 0</em>.
  3. If <em>x ≤ a</em>, then <em>b ≤ 0</em>.
  4. If <em>x ≥ a</em>, then <em>b ≥ 0</em>.

Now we proceed to rewrite each case in term of <em>difference</em> expressions:

  1. <em>x - 1/2 = 0</em>, <em>x + 1/3 = 0</em>
  2. <em>x + 3 = 0</em>
  3. <em>x - 5 ≤ 0</em>
  4. <em>x + 1/3 ≥ 0</em>

c²=24²+26²

c²=576+676

c²=1252

c=√1252

c=2√313

A die is rolled one thousand times. The percentage of aces should be around ____ or so. the first step iin computing this proble
Katyanochek1 [597]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

Box \ average =\frac{1}{6}  \\\\SD = \frac{1}{6}  \times \frac{5}{6} = \frac{5}{36} \approx 0.373\\\\Expected \ value= 1000 \times \frac{1}{6}  \approx 166.7\\\\SE = 1000 \times 0.373 \approx 11.8\\\\

The total number of aces is approximately 167, 12 or more. The SE is 12 out of 1000, which is 1.2 percent.

The percentage of aces is expected to be around 16.67% , or 1.2%.
