The variance of a data set with 10 numbers is 12 . what is the standard deviation ? a. 1.2 b. 3.46 c. 6 d. 144

Std. dev. = 3.46

Explanation:

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.

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

it has the same slope and a different y-intercept

hope this : )
