The correct question is
<span>Yuri computes the mean and standard deviation for the sample data set 12, 14, 9, and 21. he finds the mean is 14. his steps for finding the standard deviation are below. what is the first error he made in computing the standard deviation
</span>see the picture in the attached figure N 1

we know that
The formula for Sample Standard Deviation is indicated in the attached figure N2

in this problem
n=4 and Yuri had to divide in the formula by 3  

therefore
the answer is Yuri divided by n instead of n -1

What is the m12 in the matrix m
finlep [7]

Answer:

We have been given the matrix m as m = [874][205].

We can rewrite this matrix as

\begin{gathered}m=\begin{pmatrix}8 &7&4\\2&0&5 \\\end{pmatrix}\\\end{gathered}m=(827045)

Now, we need to the find m_{12}m12

It means we need to find the entity that is present in the first row and the second column.

From the above matrix, we can see that 7 is in the first row and the second column.

Therefore, we have

m_{12}= 7m12=7

Count the squares in between each letter.

Point Q is 6 units from Point R

Point R is 7 units from Point T

Point T is 3 units from Point S

For the area, it is easiest to take the area of each of those shapes and then add them.

(3*7/2) + (6*7)

10.5 + 42 = 52.5 Square Units
