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%
Answer:
Joe would be paying $700 in 5 years time.
Explanation:
I = Pin
where : I - interest
P - principal
i - the interest rate
n - the number of years
I = Pin, plug in the given data as provided in the problem.
P = $2,000
i = 0.07 per year
n = 5 years
I = ($2,000)(0.07/year)(5 years)
= ($2,000)(0.07)(5)
= $700
Answer:
radius=d/2 = 8/2 = 4inch.
Step-by-step explanation:
area = πr²
16π(inch)². or 352/7 (inch)².
hope this helps you.
3) 1 yard is 3 feets so 19 yards
4) 1 lb = 16 oz so 104 oz
The answer is 8.36 hope this helps
