Answer:
Step-by-step explanation:
The relation between the variables is given by
This is a separable differential equation. Rearranging terms:
Multiplying by -1
Integrating
Where D is a constant. Applying expoentials
Where , another constant
Solving for P
With the initial condition P=0 when t=0
We get C=-M. The final expression for P is

<span>solution:
we have, mean =8.4 hrs, std. deviation = 1.8 hrs, sample size n = 40 , X = 8.9
Probability(X<8.9) = ?
we know that, Z = (X - mean)/(std. deviation/(sqrt. n)) = (8.9 - 8.4)/(1.8/(sqrt.40))
Z = 1.7568
from standard normal probabilities table, we have , P(Z<1.7568) = 0.9608
Hence, probability that the mean rebuild time is less than 8.9 hours is 0.9608</span>
Answer:
-4 ± 2*sqrt(3)
Step-by-step explanation:
Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)
