CDE is the only tangent to circle O.
A chord is a straight line segment that connects two points on the circle. The longest chords are the ones that go through the center of the circle. Those are called diameters.

Answer: TV = 10</h3>
==============================================
Explanation
Let x be some positive real number such that
leading to the ratio
ST:TU:UV = 6x:2x:3x = 6:2:3
Note how I effectively started with 6:2:3 and multiplied all parts of the ratio by x to get 6x:2x:3x
-----------------
The parts of the ratio add up to the longest segment SV
ST+TU+UV = SV
6x+2x+3x = 22
11x = 22
x = 22/11
x = 2
Therefore,
- ST = 6x = 6*2 = 12
- TU = 2x = 2*2 = 4
- UV = 3x = 3*2 = 6
Note how ST+TU+UV = 12+4+6 = 22, which is the length of SV. This helps confirm we have the correct x value.
-----------------
The last step is to find the length of TV
TV = TU+UV
TV = 4+6
TV = 10
Or you could do
ST + TV = SV
12+TV = 22
TV = 22-12
TV = 10
Answer:

<em>Expected number of bower-birds that have bowers featuring reflective decor</em>
<em> μ = 0.9</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Sample size 'n' = 20
Given data A population consists of twenty bower-birds, six of which have bowers featuring reflective decor.
<em>probability of success </em>
Given three of the bower-birds are randomly sampled with replacement from this population.
So we will choose sample size 'n'= 3
Let 'X' be the random variable in binomial distribution
Expected number of bower-birds that have bowers featuring reflective decor
<em> μ = n p</em>
= 3 × 0.3
=0.9
<u><em>conclusion:-</em></u>
<em>Expected number of bower-birds that have bowers featuring reflective decor</em>
<em> μ = 0.9</em>
