Answer:

  • x = 9.9

Step-by-step explanation:

An equilateral triangle is the triangle with equal interior angles.

<u>Each angle has measure of 60°, therefore:</u>

  • m∠A = 60°

<u>Substitute and solve for x:</u>

  • 7x - 9.1 = 60
  • 7x = 69.1
  • x = 69.1/7
  • x = 9.9 (rounded)

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.
