<h2>Solving Compound Inequalities</h2><h3>Answer:</h3>

The third Choice

x > 1 \text{ or } x < -1

<em>Please</em><em> refer</em><em> to</em><em> the</em><em> attached</em><em> image</em><em> </em><em>for</em><em> the</em><em> </em><em>graph</em>

<h3>Step-by-step explanation:</h3>

Given:

2x +1 > 3 \text{ or } 2x -1 < -3

Let's solve for the 2x +1 > 3 part of the Compound Inequality first.

2x +1 > 3 \\ 2x > 3 -1 \\ 2x > 2 \\ x > \frac{2}{2} \\ x > 1

Now, let's solve 2x -1 < -3:

2x -1 < -3 \\ 2x < -3 +1 \\ 2x < -2 \\ x < \frac{-2}{2} \\ x < -1

We can now rewrite our Compound Inequality as x > 1 \text{ or } x < -1

What’s the answer? I can’t divide anything if it’s just x. Example: 12x+24x+30 = 467. Then you can just divide the numbers after they are added up to see what x equals. 30 and 24x + 12x won’t go together because they have x, 30 doesn’t. Move your x’s to Texas.

Public health officials believe that 90% of children have been vaccinated against measles. A random survey of medical records at
Vikentia [17]

Answer:

The answer to the question is;

Yes, it is very significant as the number of of observed vaccinated children is below the number of actually vaccinated children by 78.

Step-by-step explanation:

The result of the survey of more than 13,000 children indicate that only 89.4 % had actually been and the P-value indicate that the chance of having a sample proportion of 89.4 %  vaccinated is 1.1 %.

P is low at 0.011 for which however the proportion of those vaccinated is between 0.889 and 0.899 using a 95% confidence interval, whereby the decrease from 90 % believed to 89.9 % is small, albeit it depends on the size of the population.

At 89.4 %, in a sample of 13,000, the number of children expected to have been vaccinated but were missed is equal to 90 - 89.4 = 0.6 % = 0.006

Therefore the children missed = 78 children which is significant.
