What does 5/9-1/12 equal to?

Elena-2011 [213]

$\frac{5}{9} - \frac{1}{12} = \frac{5 \times 4}{9 \times 4} - \frac{1 \times 3}{12 \times 3}$
$= \frac{ 20}{36} - \frac{3}{36}$
$= \frac{17}{36}$

Please help me compute standard deviation! Here is the problem, as written.

aleksandr82 [10.1K]

Answer:

The standard deviation for the income of super shoppers is 76.12.

Step-by-step explanation:

The formula to compute the standard deviation for the grouped data probability distribution is:

$\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}$

Here,

<em>x</em> = midpoints

$\mu=\sum x\cdot P(x)$

Consider the Excel table attached below.

The mean is:

$\mu=\sum x\cdot P(x)=32.3$

Compute the standard deviation as follows:

$\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}$

$=\sqrt{259.71}\\\\=76.1155204\\\\\approx 76.12$

Thus, the standard deviation for the income of super shoppers is 76.12.

Which equations are in standard form? Check all that apply

professor190 [17]

Answer:

2x + 3y = -6

-4x + 3y = 12

5x + 3y = }

x - y = 5

Step-by-step explanation:

Standard Form is $Ax+By=C$ .

2x + 3y = -6, -4x +3y = 12, 5x + 3y = '?', and x - y = 5 are the equations that are in standard form.

'2x+3 = 6' does not have the 'y' to make it standard form.

'y = 2x + 5' is slope-intercept form.
