Answer:
x=4 and x= - 5
Step-by-step explanation:
In order to solve this we should re-arrange the equation:

This is equal to:

Then we can seperate this into:

So solving for x in both cases we get

Answer:
159/day
Step-by-step explanation:
Answer:
Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:

To break this down, we have:


By solving the equation:
n = 23
Thus, relating to the needed condition; n ≥ 23
The needed number of the components that should be in stock should be at least 23.
The two dice have PMFs


The sum of the two rolls can take on 8 different values:

The outcome of either roll is independent of the other, so that

a. Then PMF of
is

b. The histogram is nothing special, same as the discrete uniform distribution over the interval [0, 7].
