Answer: 93
Explanation:
Firstly, we need to know the rural.scire for the 4 tests. Since the mean for the 4 tests is a 92, the total score will be:
= 4 × 92
= 368
Since we want to know the score for he 4th test, we add the score for the 3 tests that she remembers and subtract from 368. This will be:
= 368 - (100 + 95 + 80)
= 368 - 275
= 93
She had 93 in her last test.
Answer:
Last Option
Explanation:
I'm not sure about this one so I had to google the equation real quick.
The equation for the derivative of an inverse is:
![[f^{-1}(x)]'=\frac{1}{f'(f^{-1}(x))}](https://tex.z-dn.net/?f=%5Bf%5E%7B-1%7D%28x%29%5D%27%3D%5Cfrac%7B1%7D%7Bf%27%28f%5E%7B-1%7D%28x%29%29%7D)
From my understanding of the format, it might look like a hard equation to understand but its pretty simple.
The inverse derivative is 1 divided by the derivative of f(x), except you plug in f⁻¹(x) into that derivative.
