Write y=0.83 x + 39 in standard form

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.

Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

PEMDAS

Parentheses
Exponents
Multiply
Divide
Add
Subtract

BODMAS

Brackets
Order
Divide
Add
Subtract

First, do parentheses.

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

Do multiply and divide.

6*9=54

54/3=18

Then, rewrite the problem down.

$\Longrightarrow: \sf{3+18-7}$

Add.

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

Therefore, the correct answer is "C. 14".

I hope this helps, let me know if you have any questions.
