(6m^2-2-5+m)-(3m-4+11m^2) =
<h2>
6m^2 - 2m - 124</h2>
Here BD is perpendicular bisector
So

Apply Pythagorean theorem





Answer:
0.384
Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier
we need to find the chance of getting exactly one blue from 3 parakeets

n=3, r=1, p = 0.2 , q=0.8

0.384
