Answer:
The value is
Step-by-step explanation:
From the question we are told that
The probability catching a young fish is q = 0.23
The number of fish that was caught is n = 5
Generally the probability of catching a adult fish is mathematically represented as

=>
=> 
Generally for a fish to be edible it must be an adult fish.
Generally the distribution of the number of fish the fisher man caught follows a binomial distribution
i.e

and the probability distribution function for binomial distribution is

Here C stands for combination hence we are going to be making use of the combination function in our calculators
So
=>
=>
Answer:
a. 75°
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Just replace 0 instead of x and simplify.
-20=-4x-6x
4x+6x=20
10x=20
x=20:10
x=2
proof:
-20=-4×2-6×2
-20=-8-12
(-8)+(-12)=-20
For 7 Yeah you're correct
You just need to implement the opposite
Since it's division then it turns to multiplication
For 8 also the same
