Start by changing the -2x to plus a negative 2x.

Now combine your terms.

So -10x + -2x is -12x and 14 + 12 is 26.

So our answer is -12x + 26.

Answer:

Assuming population data

$\sigma = \sqrt{0.000354}=0.0188$

Assuming sample data

$s = \sqrt{0.000425}=0.0206$

Step-by-step explanation:

For this case we have the following data given:

736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.

The first step in order to calculate the standard deviation is calculate the mean.

Assuming population data

$\mu = \frac{\sum_{i=1}^6 X_i}{6}$

The value for the mean would be:

$\mu = \frac{736.352+736.363+736.375+736.324+736.358+736.383}{6}=736.359$

And the population variance would be given by:

$\sigma^2 = \frac{\sum_{i=1}^6 (x_i-\bar x)}{6}$

And we got $\sigma^2 =0.000354$

And the deviation would be just the square root of the variance:

$\sigma = \sqrt{0.000354}=0.0188$

Assuming sample data

$\bar X = \frac{\sum_{i=1}^6 X_i}{6}$

The value for the mean would be:

$\bar X = \frac{736.352+736.363+736.375+736.324+736.358+736.383}{6}=736.359$

And the population variance would be given by:

$s^2 = \frac{\sum_{i=1}^6 (x_i-\bar x)}{6-1}$

And we got $s^2 =0.000425$

And the deviation would be just the square root of the variance:

$s = \sqrt{0.000425}=0.0206$

Alaska has 49 comic book stores with a state population of 741,204. How many people does the state have per comic book store? Ro

The number of people that the state have per comic book store 25,559

Alaska has 49 comic book stores

The population of the state is 741,204

The store has 49 comic books

Hence the number of people that the state have per comic book store can be calculated as follows

= 741,204/29

= 25,558.75

= 25,559 (to the nearest whole number)

Hence the state has 25,559 people per comic book
