What is the domain of the function y=3 in x graphed below?
2 answers:
Answer:
domain is x>0
Step-by-step explanation:
domain is the set of x values for which the function is defined
ln(negative value ) is undefined
So we take positive values for x because we have ln(x)
From the graph we can see that the given equation has a graph for x values greater than 0
the graph goes close to 0 but does not crosses y axis
So domain is x>0

Answer:
P(X=3) = 0.2013
Step-by-step explanation:
After taking and tagging the first 20 birds, then we have a proportion of 20% of tagged birds within the population, that is
Supposing that the probability (0.20) of capturing a bird <em>remains constant</em>, we may resolve it as it follows:
Capturing 10 birds can be considered as a binomial experiment with a success probability p = 0.2
Let, be the expression of the binomial distribution, for our case we have:
p=0.2
x = 3
n=10
Then,
Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%
