Answer:
The restocking level is 113 tins.
Step-by-step explanation:
Let the random variable <em>X</em> represents the restocking level.
The average demand during the reorder period and order lead time (13 days) is, <em>μ</em> = 91 tins.
The standard deviation of demand during this same 13- day period is, <em>σ</em> = 17 tins.
The service level that is desired is, 90%.
Compute the <em>z</em>-value for 90% desired service level as follows:

*Use a <em>z</em>-table for the value.
The expression representing the restocking level is:

Compute the restocking level for a 90% desired service level as follows:


Thus, the restocking level is 113 tins.
Answer:
D. 
Step-by-step explanation:
Given

Required
Determine its equivalent
<em>From the list of given options, the correct answer is</em>

This is shown as follows;

Multiply both sides by 

Open Bracket


Subtract x from both sides


Multiply both sides by -1


Reorder

<em>Hence, the correct option is D</em>

Answer:

Step-by-step explanation:
The first case is a special case of the second one, so we will solve the question for the second case first.
Consider
. Using the properties of derivatives and the derivatives of trigonometric functions we get that


We have the equation
. Note that since
then we have the equation
,
which implies that
. Then, 
Note that in this case, the value of k doesn't depend on the values of A and B. So, it applies to every value of A and B. The first case is included, since it is the case in which A=0 and B=1.
Answer:

Below is the procedure that was used to find the answer.
Step-by-step explanation:
Let be "e" the weight in pounds of the elephant and "c" the weight in pounds of the cat.
According to the information provided in the exercise, we know that The weight of an elephant is
times the weight of a cat. Based on this we can write the following equation:

If the weight in pounds of the elephant is:

We must substitute this value into the equation and then solve for "c" in order to find the weight in pounds of the cat.
Then we get:
