Answer:
<h2>10 units</h2>
Step-by-step explanation:
It's important to know that the centroid is always two-thirds of the median. Which means

Which means
.
But, the centroid has always the same distance from each vertex, which means

Therefore, BG is 10 units long.
Answer: 0.26
Step-by-step explanation:
As per given , we have
P(green tail) = 0.36
P(red fins) = 0.59
P(both a green tail and red fins ) = 0.21
Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )
<em>[P(neither A nor B)= 1- P(either A or B)]</em>
= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))
<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>
= 1- (0.36+0.59-0.21)
= 1-(0.74)
= 0.26
Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26
The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.
If x = 2 bisects ab, then a and b are equal distances from x = 2.
a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.
The coordinate of b is (8, 1)
