Iii i think sorry if im wrong
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
=>
=>
We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have 
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
Answer:
A) because b=c it is an equlateral triangle.
The interior Angles of a triangle is always equal to 180 .
Therefore 180-38 =142
because B=C
142÷2 =71
