Answer:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:
Where and
We want to find this probability:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using this formula we got:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
Domain: (-6, 0, 3) Range: (-9, -7, 3, 5)
5m − 3h = 45
Subtract 5m from both sides
-3h = 45 - 5m
Divide both sides by -3
h = (45 - 5m)/ -3
h = -15 + 5m/3
