We need to find the probability that a selected animal will be an threatened given they are a bird: P(T/B). So,
![P(T/B)= \frac{P(T\cap B)}{P(B)}](https://tex.z-dn.net/?f=%20P%28T%2FB%29%3D%20%5Cfrac%7BP%28T%5Ccap%20B%29%7D%7BP%28B%29%7D%20%20)
Where, Probability of threatened animal that are birds:
= ![\frac{15}{475}](https://tex.z-dn.net/?f=%20%5Cfrac%7B15%7D%7B475%7D%20%20)
and probability of bird=![\frac{90}{475}](https://tex.z-dn.net/?f=%20%5Cfrac%7B90%7D%7B475%7D%20%20)
Therefore, P(T/B)= \frac{P(T\cap B)}{P(B)}
= ![\frac{\frac{15}{475}}{\frac{90}{475}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Cfrac%7B15%7D%7B475%7D%7D%7B%5Cfrac%7B90%7D%7B475%7D%7D%20%20%20%20)
=![\frac{15}{90}](https://tex.z-dn.net/?f=%20%5Cfrac%7B15%7D%7B90%7D%20%20)

Answer:
y = 36
Step-by-step explanation:
so there directly proportional..so lets make a proportion
if y = 9 when x = 5, what is the value of y when x = 20...
5 20
------ = ----- (cross multiply)
9 y
(5)(y) = (20)(9)
5y = 180
y = 180/5
y = 36 <=== so when x = 20, y = 36
Answer:
x = 14
BE = 6
Step-by-step explanation:
to find 'x': BG = 1/2[(x-9) + (3x-13)]
BG = 4x-22 / 2
BG = 3x-25
3x-25 / 1 = 4x-22 / 2
cross-multiply:
4x-22 = 2(3x-25)
4x-22 = 6x-50
-2x = -28
x = 14
to find 'BE': CB = BE
2x+4 = 7x-1
-5x = -5
x = 1
BE = 7(1) - 1
BE = 6
The pree tax amount count as 100%, then there's the 7% tax and lastly the 20% tip. therefore, one would pay (100+20+7)% of $84.00.
127% of $84.00
(127/100) * $84.00 = $106.68
