x+3-1.26923+4.12821 so if I am wrong it took me a while to work this out
Student 4 has the largest percent error.
Step-by-step explanation:
The percent error of a measurement is given by
![p=\frac{|x-x_{true}|}{x_{true}}\cdot 100](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B%7Cx-x_%7Btrue%7D%7C%7D%7Bx_%7Btrue%7D%7D%5Ccdot%20100)
where
x is the value of the measurement
is the actual value
For student 1:
![x=49\\x_{true}=50](https://tex.z-dn.net/?f=x%3D49%5C%5Cx_%7Btrue%7D%3D50)
Percent error:
![p=\frac{|49-50|}{50}\cdot 100=0.02\cdot 100=2\%](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B%7C49-50%7C%7D%7B50%7D%5Ccdot%20100%3D0.02%5Ccdot%20100%3D2%5C%25)
For student 2:
![x=25.5\\x_{true}=25](https://tex.z-dn.net/?f=x%3D25.5%5C%5Cx_%7Btrue%7D%3D25)
Percent error:
![p=\frac{|25.5-25|}{25.5}\cdot 100=0.0196\cdot 100 = 1.96\%](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B%7C25.5-25%7C%7D%7B25.5%7D%5Ccdot%20100%3D0.0196%5Ccdot%20100%20%3D%201.96%5C%25)
For student 3:
![x=7.5\\x_{true}=8](https://tex.z-dn.net/?f=x%3D7.5%5C%5Cx_%7Btrue%7D%3D8)
Percent error:
![p=\frac{|7.5-8|}{8}\cdot 100=0.0625\cdot 100 = 6.25\%](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B%7C7.5-8%7C%7D%7B8%7D%5Ccdot%20100%3D0.0625%5Ccdot%20100%20%3D%206.25%5C%25)
For student 4:
![x=2.1\\x_{true}=1.6](https://tex.z-dn.net/?f=x%3D2.1%5C%5Cx_%7Btrue%7D%3D1.6)
Percent error:
![p=\frac{|2.1-1.6|}{1.6}\cdot 100=0.3125\cdot 100 = 31.25\%](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B%7C2.1-1.6%7C%7D%7B1.6%7D%5Ccdot%20100%3D0.3125%5Ccdot%20100%20%3D%2031.25%5C%25)
So, student 4 has the largest percent error.

Answer:
r = ∛(3V/4π)
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³.
We want to solve this first for r³ and then for r.
Multiplying both sides of V = (4/3)πr³ by 3 yields an equation without fractions: 3V = 4πr³.
Dividing both sides of this equation by 4π isolates r³:
3V
r³ = -------
4π
To find r, take the cube root of both sides of
3V
r³ = -------
4π
obtaining r = ∛(3V/4π)
