Answer:
<em>Std. dev. = 3.46</em>
<u><em>Explanation:</em></u>
The standard deviation is the square root of the variance.
Given that, Varience of 10 numbers = 12
S.D = √V
Where,
S.D = Standard Deviation
V = variance
S.D = √12
S.D = 3.46
Both standard deviation and variance are derived from the mean of a given data set. If the mean is simply the average of all data points, the variance measures the average degree to which each point differs from the mean.

Answer:
x = -48
Step-by-step explanation:
3/8 x - 6 = -24
Add 6 to each side
3/8 x - 6+6 = -24+6
3/8 x = -18
Multiply each side by 8/3 to isolate x
8/3 * 3/8x = 8/3 *-18
x = -48
Let check
3/8 (-48) -6 = -24
-18 - 6 = -24
-24=-24
This checks so this is the solution
