Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=
+
+
a) Zx b) Zy
In differentiation, if y = axⁿ, y' =
. Applying this in question;
Given the function z = x⁸+
+

Note that y is treated as a constant since we are to differentiate only with respect to x.
For Zy;

Here x is treated as a constant and differential of a constant is zero.
Answer:
The probability that the service desk will have at least 100 customers with returns or exchanges on a randomly selected day is P=0.78.
Step-by-step explanation:
With the weekly average we can estimate the daily average for customers, assuming 7 days a week:

We can model this situation with a Poisson distribution, with parameter λ=108. But because the number of events is large, we use the normal aproximation:

Then we can calculate the z value for x=100:

Now we calculate the probability of x>100 as:

The probability that the service desk will have at least 100 customers with returns or exchanges on a randomly selected day is P=0.78.
Y = 12x - 40
the x variable represents the number of hours Sam works at the airport
the y value represents the amount in dollars that Sam has after paying Daniel
the 12 is the amount in dollars that Sam earns per hr
the 40 is the amount in dollars Sam owes Daniel
Answer:
At most 800 magazines the company can print daily with the remaining number of ink cartridges.
Step-by-step explanation:
We are given the following in the question:

The above inequality gives the relation for daily supply of ink cartridges where N is the number of newspaper and M is the number of magazines.
Number of newspaper to be printed daily,N = 8000
We have to find the number of magazines at most can the company print daily with the remaining number of ink cartridges.
Puting the value in the given inequality,

Thus, at most 800 magazines the company can print daily with the remaining number of ink cartridges.
