7? im not sure though, i thnink im wrong though
Answer:
17
Step-by-step explanation:
The sum of squares of the coordinates is (−8)²+(15)²= 289.
Therefore, the magnitude ∥v⃗ ∥ =√289= 17
vector magnitude is ∥v⃗ ∥= 17.
8/7 This is the correct answer please mark it brainly!
Number of brown trout = 6
Number of lake trout = 18
Total number of trouts = 
Probability to catch a lake trout first time = 
As the fisherman let the trout go, so probability for the second time is =

Hence, the probability becomes=

= 
The probability to find the brown trout is 
as , 
=
