The estimated value is given by the expected value. The estimated number of clownfish in the store that have fin rot will be 216.
<h3>How to find that a given condition can be modeled by binomial distribution?</h3>
Binomial distributions consist of n independent Bernoulli trials.
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
The expected value of X is:
Nemo's fish store has 12 tanks of clownfish: each tank holds 30 fish.
He collects and inspects 5 fish from each tank and finds that 3 fish have fin rot
Then the estimated number of clownfish in the store that have fin rot.
The number of the clownfish in the store will be
n = 12 × 30
n= 360
Then the value of p will be
Then the estimated number of clownfish in the store that have fin rot will be given by the expected value. Then we have

Answer:
3225
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
[ 2a + (n - 1)d ]
where a is the first term and d the common difference
here a = 6 and
d = 13 - 6 = 20 - 13 = 7, hence
= 
[ (2 × 6) + (29 × 7) ]
= 15(12 + 203) = 15 × 215 = 3225
Answer:
The second bubble
Explanation
You need to make your exponents equal the other side so to do this;
Distribute the 3 in the exponent "3(x-2)"
Which is 3x-6
And since multiplying exponents adds them, you need a -6 to make the two equal.
So your exponent should equal -6 to make that statement true
we have that

statements
case a) The domain is {x|x ≤ –2}-------> Is False
the domain is all real numbers---------> the interval (-∞,∞)
case b) The range is {y|y ≤ 6}.------> Is True
The range is the interval (-∞,6]
case c) The function is increasing over the interval (–∞ , –2).-----> Is True
See the attached figure
case d)The function is decreasing over the interval (−4, ∞).-----> Is False
In the interval (-4,-2) the function is increasing and in the interval (-2,∞) the function is decreasing (See the attached figure)
case e)The function has a positive y-intercept.------> Is True
The value of y-intercept is
