I believe that the answer to the question provided above is that standard deviation in definition is how scattered the data are, thus it will determinr possible outliers.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

The mean is 52 inches.

49, 50, 51, 52, 53, 54, 55 add the numbers all together then divide 364 by 7 = 52

A line passes through the points (7, 8) and (–7, 10). What is its equation in slope-intercept form?

iris [78.8K]

Answer:

$y=-\frac{1}{7}x+9$

Step-by-step explanation:

The slope-intercept formula is:

$y=mx+b$

y= keep as variable

m= slope of the line

x= keep as variable

b= y-intercept of the line.

Hope this helped!

Let A be a 3 by 6 , B be a 6 by 7 and C be a 7 by 3 matrix. Determine the size of the following matrices (if they do not exist,

kozerog [31]

Answer:

a. AB: 3 by 7

b. BA: N by N

c. A^TB: N by N

d. BC: 6 by 3

Step-by-step explanation:

Given

$A =3\ by\ 6$

$B =6\ by\ 7$

$C =7\ by\ 3$

Required

The dimension of the following matrices

As a general rule:

For A * B to be successful, the columns in a must equal the rows in B

Using this rule, we have:

$A_{m*n} * B_{n * p} = AB_{m*p}$

So:

$(a)\ AB$

$A_{3*6} * B_{6*7} \to AB_{3 * 7}$

$(b)\ BA$

$B_{6*7} * A_{3*6} \to AB_{N * N}$

The column numbers of B does not equal the row numbers of A.

Hence, BA does not exist

$(c)\ A^TB$

$A^T$ implies that:

If $A =3\ by\ 6$ , then

$A^T = 6\ by\ 3$

So:

$A^T_{6*3} * B_{6,7} \to A^TB_{N*N}$

The column numbers of A^T does not equal the row numbers of B.

Hence, $A^TB$ does not exist

$(d)\ BC$

$B_{6*7} * C_{7*3} \to BC_{6,3}$
