Answer:

option - d

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + b^2 = 13^2

81 +b^2 = 169

b^2 = 169 - 81 = 88

b= \sqrt{88} = \sqrt{2 x 2 x2 x 11} ( take the one doubling out )

           \sqrt[2]{2  x 11 } = \sqrt[2]{22}

Answer:

d

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

 x² + 9² = 13²

x² + 81 = 169

       x² = 169 - 81

      x² = 88

      x = \sqrt{88}

     x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}

The scatter plot shows a correlation between the years and the rainfall in centimeters in Tennessee.
nataly862011 [7]

Answer:

7

4

Step-by-step explanation:

The <u>actual values</u> are shown on the given graph as <u>blue points</u>.

The <u>line of regression</u> is shown on the given graph as the <u>red line</u>.

From inspection of the graph, in the year 2000 the actual rainfall was 43 cm, shown by point (2000, 43).  It appears that the regression line is at y = 50 when x is the year 2000.

⇒ Difference = 50 - 43 = 7 cm

<u>In 2000, the actual rainfall was </u><u>7</u><u> centimeters below what the model predicts</u>.

From inspection of the graph, in the year 2003 the actual rainfall was 44 cm,  shown by point (2003, 40).  It appears that the regression line is at y = 40 when x is the year 2003.

⇒ Difference = 44 - 40 = 4 cm

<u>In 2003, the actual rainfall was </u><u>4</u><u> centimeters above what the model predicts.</u>
