Step-by-step explanation:

5/3x +35-3/2x+12=0

5/3x -3/2x+35+12=0

1/6x+47=0

1/6x=-47

divide through by 6x

×=1/282

5 (1/3x + 7) - 3 (1/2x - 4)

1/3x = x/3

1/2x = x/2

5 (x/3 + 7) - 3 (x/2 - 4)

Expand with the multiplier 5

= 5x/3 + 35 - 3 (x/2 - 4)

Expand with the multiplier -3

= 5x/3 + 35 - 3x/2 + 12

Simplify the problem

= x/6 + 47

Therefore 5 (1/3x + 7) - 3 (1/2x - 4) is equivalent to x/6 + 47

Consider the equation ay'' + by' + cy = d, where a, b, c, and d are constants. (a) find all equilibrium, or constant, solutions

Orlov [11]

Rewrite equation so that it is homogeneous .
$ay'' +by' + cy = 0$

Solve characteristic equation:
$ar^2 +br + c = 0 \\ \\ r = \frac{(-b) \pm \sqrt{b^2 -4ac}}{2a}$

The solutions to the homogeneous equation are:
$y = k_1 e^{r_1 t} + k_2 e^{r_2 t}$

Finally you need the constant term in "cy" to equal 'd' to satisfy the particular solution.
$y= k_1 e^{r_1 t} + k_2 e^{r_2 t} + \frac{d}{c}$

What is the Z-score for Paula if she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275? step by step how

Setler [38]

mu = 1100 = population mean

sigma = 275 = population standard deviation

x = 1400 = raw score

z = z score

z = (x-mu)/sigma

z = (1400-1100)/(275)

z = 300/275

z = 1.0909090909091 approximately

z = 1.09

Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).

The positive z score is due to Paula's raw score being above the mean.
