The answer is 4.5, since integer is the opposite.
Answer:
220/4
55 x min
Step-by-step explanation:
they tell you its 220 beats in 4 mins to find the beats per minute divide 220 by 4
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)
=0.1667
=16.67%
Answer:
The value of x is 11.
Step-by-step explanation:
The given number is 0.27272727..., and it is converted to the fraction as
..... (1)
Multiply both sides by 100.
![0.272727...\times 100=\frac{3}{x}\times 100](https://tex.z-dn.net/?f=0.272727...%5Ctimes%20100%3D%5Cfrac%7B3%7D%7Bx%7D%5Ctimes%20100)
.... (2)
Subtract equation (1) from equation (2),
![27.272727-0.272727...=\frac{300}{x}-\frac{3}{x}](https://tex.z-dn.net/?f=27.272727-0.272727...%3D%5Cfrac%7B300%7D%7Bx%7D-%5Cfrac%7B3%7D%7Bx%7D)
![27=\frac{300-3}{x}](https://tex.z-dn.net/?f=27%3D%5Cfrac%7B300-3%7D%7Bx%7D)
Multiply both sides by x.
![27x=297](https://tex.z-dn.net/?f=27x%3D297)
Divide both sides by 27.
![x=\frac{297}{27}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B297%7D%7B27%7D)
![x=11](https://tex.z-dn.net/?f=x%3D11)
Therefore the value of x is 11.
