X^2 +2x-24
C is the answer
Given:
square shape.
diagonal = 44 inches
The frame is square shape therefore its side lengths are equal. We need to solve for the side length using the diagonal.
a = √2 d/2
a = √2 44/2
a = √2 22
a = 1.414 * 22
a = 31.112 or 31 inches
Perimeter: 31 inches * 4 sides = 124 inches
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%
