Answer:
the length of the edge of a cube with a volume of 125 is 5.
Step-by-step explanation:
This is an increase and it increased by 40% because the difference between 140 and 100 is 40 which is 40% of 100.
Answer:
250mL
Step-by-step explanation:
500 * 0.75 = 375
375 * 2/3 = 250
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%
