Answer:


And we can find this probability with this difference:

And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
Explanation:
For this case we can define the random variable X as "hours that a person watches television". For this case we don't have the distribution for X but we have the following parameters:

We can assume that the distribution for X is normal

And we want to find this probability:

And we can use the z score formula given by:

And we can find the z score for each limit and we got:


And we can find this probability with this difference:

And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
Answer:
[a]. 0.49.
[2]. 0.536
[c]. 4.15 kmol; 5.84 kmol.
Explanation:
Without mincing words let's dive straight into the solution to the question above.
[a].
The initial external reflux ratio, LD that must be used = [(0.85 - 0.57)/ 0.85 - 0]/ [ 1 - (0.85 - 0.57)/ 0.85 - 0].
The initial external reflux ratio, LD that must be used = 0.329/ 1- 0.329 = 0.49.
[b].
The final external reflux ratio that must be used = [ 0.85 - 0.13/ 0.85 - 0]/ [ 1 - 0.85 - 0.13/ 0.85 - 0].
Hence, the final external reflux ratio that must be used =0.847/ 1 - 0.847 = 5.536.
[c].
The amount of distillate product that is withdrawn:
4 = 0.85 H(t) + 0.8 - 0.08.
H(t) = 4.15 kmol, and the value of Wfinal = 5.84 kmol.
Answer: Comer bien ayuda a reducir el riesgo de problemas de salud física como enfermedades cardíacas y diabetes. También ayuda con los patrones de sueño, los niveles de energía y su salud en general. Es posible que haya notado que su estado de ánimo a menudo afecta los tipos de alimentos que elige, así como la cantidad que come.
English Translation: Eating well helps to reduce the risk of physical health problems like heart disease and diabetes. It also helps with sleeping patterns, energy levels, and your general health.
