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:
84
Step-by-step explanation:
substitute n = 5 into the expression
16n + 4
= 16(5) + 4
= 80 + 4
= 84
Answer:
g(x) = |x-7|+4
Step-by-step explanation:
If we imagine trying to find the vertex of f(x) or the lowest part, we can always input x and y into each equation and see if they equal on either side.
The vertex is at points (7,4)
4=|7-7|+4 : 4=4.
Answer:
1) claire's stone at 1.25 seconds
2) 0.5 seconds and its max height was 9
3) lin at 8ft
Step-by-step explanation:
the intercepts tell you the first and third question and then the max height is the highest point on the graph
not sure what measurements you were supposed to use so I used seconds and feet and if that's not it then it's the same numbers just different words
36^2 + 27^2 = C^2
1296 + 729 = C^2
2025 = C^2
C = 45
45 feet is the length of the hypotenuse
Have a great day!!
