Answer:
Now we can find the expected value with this formula:
And replacing we got:
Step-by-step explanation:
For this case we know the following probability mass function given:
For this case we need to satisfy the following condition in order to have a probability distribution function:
And we have this:
Now we can find the expected value with this formula:
And replacing we got:
Answer:
Sneakerheadz produced 900 pairs on Sunday. And on Monday, they produced shoes at a rate of 300 per hour.
Then the total number of pairs produced is:
S(t) = 900 + 300*t
where t represents the number of hours worked on Monday.
We know that Nuckicks only worked on Monday, and the same amount of time as Sneakerheadz, but at a rate of 480 sneakers per hour.
We can write the total number of pairs as:
N(t) = 480*t
Now we know that Nukcicks produced in Monday the sane number of pairs than Sneakerheadz produced in the two days, then we have that:
S(t) = N(t)
900 + 300*t = 480*t
900 = 480*t - 300*t = 180*t
900/180 = t
5 = t
So the factories operated 5 hours on Monday.
