![(1)p(x)\geq 0\\(2)\int_{0}^{\infty} p(x) dx=0](https://tex.z-dn.net/?f=%281%29p%28x%29%5Cgeq%200%5C%5C%282%29%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20p%28x%29%20dx%3D0)
Explanation:
A function f(x) is a Probability Density Function if it satisfies the following conditions:
![(1)f(x)\geq 0\\(2)\int_{0}^{\infty} f(x) dx=0](https://tex.z-dn.net/?f=%281%29f%28x%29%5Cgeq%200%5C%5C%282%29%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20f%28x%29%20dx%3D0)
Given the function:
![p(x)=\dfrac{1}{r}e^{-x/r} \: on\: [0,\infty), where\:r=\dfrac{20}{ln(2)}](https://tex.z-dn.net/?f=p%28x%29%3D%5Cdfrac%7B1%7D%7Br%7De%5E%7B-x%2Fr%7D%20%5C%3A%20on%5C%3A%20%5B0%2C%5Cinfty%29%2C%20where%5C%3Ar%3D%5Cdfrac%7B20%7D%7Bln%282%29%7D)
(1)p(x) is greater than zero since the range of exponents of the Euler's number will lie in ![[0,\infty).](https://tex.z-dn.net/?f=%5B0%2C%5Cinfty%29.)
(2)
![\int_{0}^{\infty} p(x)=\int_{0}^{\infty} \dfrac{1}{r}e^{-x/r}\\=\dfrac{1}{r} \int_{0}^{\infty} e^{-x/r}\\=-\dfrac{r}{r}\left[e^{-x/r}\right]_{0}^{\infty}\\=-\left[e^{-\infty/r}-e^{-0/r}\right]\\=-e^{-\infty}+e^{-0}\\SInce \: e^{-\infty} \rightarrow 0\\e^{-0}=1\\\int_{0}^{\infty} p(x)=1](https://tex.z-dn.net/?f=%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20p%28x%29%3D%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20%5Cdfrac%7B1%7D%7Br%7De%5E%7B-x%2Fr%7D%5C%5C%3D%5Cdfrac%7B1%7D%7Br%7D%20%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20e%5E%7B-x%2Fr%7D%5C%5C%3D-%5Cdfrac%7Br%7D%7Br%7D%5Cleft%5Be%5E%7B-x%2Fr%7D%5Cright%5D_%7B0%7D%5E%7B%5Cinfty%7D%5C%5C%3D-%5Cleft%5Be%5E%7B-%5Cinfty%2Fr%7D-e%5E%7B-0%2Fr%7D%5Cright%5D%5C%5C%3D-e%5E%7B-%5Cinfty%7D%2Be%5E%7B-0%7D%5C%5CSInce%20%5C%3A%20e%5E%7B-%5Cinfty%7D%20%5Crightarrow%200%5C%5Ce%5E%7B-0%7D%3D1%5C%5C%5Cint_%7B0%7D%5E%7B%5Cinfty%7D%20p%28x%29%3D1)
The function p(x) satisfies the conditions for a probability density function.
Answer:
Explanation:
F = ma. For us, this looks like
60 = 30a and
a = 2 m/s/s
If the force goes up to, say, 90, then
90 = 30a and
a = 3...if the force goes up, the acceleration also goes up.
If the mass goes up to say, 60, and the force stays the same, then
60 = 60a and
a = 1...if the mass goes up, the acceleration goes down.
Answer:
discrimination: prejudice towards a person/group based on their race, sex, age, and/or sexual orientation
Explanation:
People of color face discrimination because of the color of their skin.
