if the variance of the data values in a sample is 361, what is the standard deviation of the data values​

The standard deviation is 15 in the sample of data values

Step-by-step explanation:

Variance is simply the square of the standard deviation  

(  v  =  σ  2 ) .

So if the variance is 225,  

σ  =  √

225  or 15.

the answer is 19

Step-by-step explanation:

a p e x

step-by-step explanation:

i hope this : )

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
