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.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
