Answer:
1 / 5
Step-by-step explanation:
Given that:
Number of white marbles = 5
Number of blue marbles = 3
Number of green marbles = 7
Required is the approximate probability of drawing 2 green marbles, Note that drawing is done without replacement :
Probability = required outcome / Total possible outcomes
Total possible outcomes = sum of all marbles = (5 + 3 + 7) = 15 marbles
First draw:
P(Green) = 7 / 15
Second draw:
Required outcome = 7 - 1 = 6
Possible outcomes = 15 - 1 = 14
P(green) = 6 / 14
Probability of drawing out two green marbles :
(7/15 * 6/14) = 42 / 210 = 1 / 5
H^2=13^2-5^2
h^2=169-25
h^2=144
h=V144
h=12
A=b*h/2=10*h/2
A=10*12/2=120/2=60 cm^2
The given function is
![h(x) = \{ (0,1), (2,3), (-4, 1) \}](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5C%7B%20%280%2C1%29%2C%20%282%2C3%29%2C%20%28-4%2C%201%29%20%5C%7D)
The inverse function is
![h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}](https://tex.z-dn.net/?f=h%5E%7B-1%7D%28x%29%20%3D%20%5C%7B%20%281%2C0%29%2C%20%283%2C2%29%2C%20%281%2C-4%29%5C%7D)
To get the inverse, we swap each x and y coordinate.
The rule is ![(x,y) \to (y,x)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Cto%20%28y%2Cx%29)
So that's why the point (0,1) becomes (1,0) for instance.
