Simplify the complex fraction: ((3x-7)/x^2)/(x^2/2)+(2/x)

\dfrac{ \dfrac{3x-7}{x^2} }{ \dfrac{x^2}{2} } + \dfrac{2}{x} =\qquad \qquad x \neq 0\qquad x^4 \neq 0 \\  \\  \\  \dfrac{(3x-7)*2}{x^2*x^2}+ \dfrac{2}{x} =  \\  \\  \\   \dfrac{6x-14}{x^4}+ \dfrac{2}{x} =\\  \\  \\  \dfrac{ 6x-14 }{ x^4 }+ \dfrac{2(x^3)}{x(x^3)}=\\  \\  \\  \boxed{  \dfrac{ 6x-14 +2x^3}{ x^4 } }

Can you explain it and help me out please​
shusha [124]

Answer:

D. two real solutions

Step-by-step explanation:

p²+5 = 6p

p² - 6p +5 =0

D = b² - 4ac = (-6)² - 4*(1)*5 = 36 - 20 = 16

D > 0, so this equation has 2 real solutions

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours. What is the mean absolute deviati
Irina-Kira [14]

The mean absolute deviation for the number of hours students practiced the violin is 6.4.

<h3>What is the mean absolute deviation?</h3>

The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.

Given

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.

The given data set is;

45, 38, 52, 58, 42

Mean Deviation = Σ|x − μ|/N.

μ = mean, and N = total number of values

|x − μ| = |45 − 47| = 2

|38− 47| = 9

|52− 47| = 5

|58− 47| = 11

|42− 47| = 5

The mean absolute deviation for the number of hours students practiced the violin is;

\rm Mean =\dfrac{2+9+5+11+5}{5}\\\\Mean=\dfrac{32}{5}\\\\Mean = 6.4

Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.
