Suppose the line of best fit is being found for some points that have an r-value of 0.769. If the standard deviation of the x-co
jeyben [28]

r value i.e Correlation between x value and y value = 0.769

A_{x}=Standard deviation of the x-coordinate = 5.508

 A_{y}=Standard deviation of the y-coordinate = ?=k

Slope of line is given by formula

If slope of line is m, then

m = r\times \frac{ A_{x}}{A _{y}}

m= 0.769 \times \frac{k}{5.508}

Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.

Enter the indicated element.
Ymorist [56]

a_{1,3} = 9

Step-by-step explanation:

The elements of matrices are represented in the form

a_{r,c}

Here r is the row number and c is the column number.

Given matrix is:

A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]

The elements of matrix will be represented by a_{r,c}

We have to find a_{1,3}

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

So,

a_{1,3} = 9

Is 4y - 8 &gt; 10 true?
steposvetlana [31]

4y-8>10

Add 8

4y-8+8>10+8

4y>18

Now divide both sides by 4

4y/4 > 18/4

y>9/2


Now let's see if it will be true

Replace y by its value

4(9/2)-8>10

36/2 -8 > 10

18-8 > 10

10 > 10

That's false because 10 can not smaller than 10

so it should be = instead


Answer : False


I hope that's help:)
