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:
Carol bought 3.8 pounds of meat.
Step-by-step explanation:
1 pork chop = 0.35 pounds.
4 pork chops x 0.35 pounds = 1.4 pounds.
1 steak = 0.8 pounds.
3 steaks x 0.8 pounds = 2.4 pounds.
2.4 pounds of steak + 1.4 pounds of pork chops = 3.8 pounds of meat.
Now that's a lot of meat.
Yes. If the diagonals of a quadrilateral are perpendicular to each other, then the quadrilateral is always rhombus.
