Answer:
<h2>MN = 9.1 cm</h2>
Step-by-step explanation:
If MN is tangent of a circle then the angle M is a right angle.
We have a dimeter of acircle d = 8 cm.
Therefore the radius CM = 8 cm : 2 = 4cm.
In a right triangle CMN use the Pythagorean theorem:

Substitute CM = 4cm and CN = 9.9 cm:

<em>subtract 16 from both sides</em>

There is literally no question
r = correlation coefficient

If: Sxx = 10, Syy = 40, Sxy = 10, then:

They are equal because
1 yd=3ft
25 yds= x feet
x= 25*3
feet=75
