Answer:

Step-by-step explanation:
<u>Differentiation</u>
We have a relationship between x and y as follows:

Both variables depend on time t for t≥0.
Differentiating with respect to time:

Applying the derivative of a power function:

Recall the derivative of a constant is 0.
Dividing by 2:

Solving for y':

At some specific time, we have:
x=3, y=4, dx/dt = x' = 6. Substituting:

Operating:

Simplifying:

The equation would be: C = 5.5T, where C is the Cost and T is the number of tubes.
If you divide all of the outputs by the inputs, you will get 5.5. That means it's a proportional relationship. Just multiply the number of tubes by 5.5 and you will have your cost.
Answer:
2/3
Step-by-step explanation:
So we have 10%+5%=15% of clients under the condition "permanent", and we can find the probability that a client in that group requested a haircut:
P(haircut | permanent)=10%/15%=2/3
