In general, the most probable distribution is in the ratio of the respective types, namely
Number of blue tails
=12*(53/(53+40))
=6.84
To check between 6 or 7, we use the hypergeometric distribution:
P(B=6)
=C(40,6)C(53,6)/(C(93,12)
=3838380*22957480/416579843773639
=0.211530
P(B=7)
=C(40,5)C(53,7)/(C(93,12)
=658008*154143080/416579843773639
=65563917120/269282381237
=0.243476
Hence the most probable number of blue tail fishes is 7
Note: it would be prudent to calculate P(B=8)=0.194443 to show that P(B=7) is indeed the highest value.
Answer:
y=1
Step-by-step explanation:
Let's solve by opening the bracket first
-5-(15y-1)=2(7y-16)-y
Open the bracket
-5-15y+1=14y-32-y
Collect like terms
-5+1+32=14y-y+15y
-5+33=14y+14y
28=28y
Divide both sides by 28
y=1
Therefore the final answer is 1
1. being destroyed would be a negative number
2. water increasing in temperature is a positive number
3.descending would be a negative number
4. credit card charge would be a positive number
Rohanfighter is right, it's D
Pretty sure that's right.
