Answer:
![x^3+1](https://tex.z-dn.net/?f=x%5E3%2B1)
Step-by-step explanation:
![26(x^3+1)^2-22(x^3+1)-3=0](https://tex.z-dn.net/?f=%2026%28x%5E3%2B1%29%5E2-22%28x%5E3%2B1%29-3%3D0%20)
Comparing to
![A(u)^2+B(u)+C =0](https://tex.z-dn.net/?f=%20A%28u%29%5E2%2BB%28u%29%2BC%20%3D0%20)
Where A,B,C are constants
You should see that we need to substitute the
with u.
Answer:
63%
Step-by-step explanation:
This is a problem of conditional probability.
The two events that are given are:
- Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
- Require a tow truck - Let it be event T.
We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)
We are also given the conditional probability, which is P(T | S) = 90% = 0.90
Using the given formula for our case we can modify the formula as:
![P(T|S)=\frac{P(S \cap T)}{P(S)}](https://tex.z-dn.net/?f=P%28T%7CS%29%3D%5Cfrac%7BP%28S%20%5Ccap%20T%29%7D%7BP%28S%29%7D)
![0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63](https://tex.z-dn.net/?f=0.90%3D%5Cfrac%7BP%28S%20%5Ccap%20T%29%7D%7B0.70%7D%5C%5C%5C%5C%20P%28S%20%5Ccap%20T%29%3D0.90%20%5Ctimes%200.70%5C%5C%5C%5C%20P%28S%20%5Ccap%20T%29%3D0.63)
Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out
Answer: The answer is 40 minutes.
Equation: If m is the total number of minutes it takes him to complete his homework, 30% of m is given by 0.3m. Since 30% was done in 12 minutes, we have 0.3m=12.
