\frac{x}{x - 2} + \frac{x + 2}{x} \ \textgreater \ 2
\frac{x(x)}{x(x - 2)} + \frac{(x - 2)(x + 2)}{x(x - 2)} \ \textgreater \ 2
\frac{x^{2}}{x(x - 2)} + \frac{x^{2} - 4}{x(x - 2)} \ \textgreater \ 2
\frac{x^{2} + x^{2} - 4}{x(x - 2)} \ \textgreater \ 2
\frac{2x^{2} - 4}{x(x - 2)} \ \textgreater \ 2
2x(x - 2) \ \textgreater \ 2x^{2} - 4
2x^{2} - 4x \ \textgreater \ 2x^{2} - 4
-4x \ \textgreater \ 4

In a large county in Central Pennsylvania, 42% of all registered voters are Democrats and 53% are Republicans. What is the proba
AVprozaik [17]

Answer:

Probability [Randomly selected voter affiliated with other party] = 1/20

Step-by-step explanation:

Given:

Percentage of Democrats voters = 42%

Percentage of Republican voters = 53%

Find:

Probability [Randomly selected voter affiliated with other party]

Computation:

Percentage of other party voters = 100% - [Percentage of Democrats voters + Percentage of Republican voters]

Percentage of other party voters = 100% - [42% + 53%]

Percentage of other party voters = 100% - 95%

Percentage of other party voters = 5%

Probability [Randomly selected voter affiliated with other party] = Percentage of other party voters / 100%

Probability [Randomly selected voter affiliated with other party] = 5% / 100%

Probability [Randomly selected voter affiliated with other party] = 1/20

Point E is on line segment DF. Given DE<br> EF.<br> 6 and DF =9, determine the length EF
nlexa [21]

Answer:

<h2>3</h2>

Step-by-step explanation:

IF point E lies on the line segment DF, this means that all the points DEF are collinear and DE+EF = DF.

Given parameter

DE = 6

DF = 9

Required

EF

Substituting the given parameter into the expression above to get the required will be;

DE+EF = DF.

EF = DF-DE

EF = 9-6

EF = 3

Hence the length of EF is equivalent to 3
