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.

Without actually carrying out the steps of multiplication, determine whether the product of 15.1 and 0.9 will be larger or small
yan [13]

Answer: Smaller

Step-by-step explanation: The product of 15.1 and 0.9 will be smaller than 15.1. This is because 0.9 is smaller than 1 and since 15.1 * 1 is 15.1, we know that anything smaller than 1 will result in the product of it and 15.1 being smaller.
