Answer:
True
Step-by-step explanation:
The least total cost method is the method in which the total cost of the ordering cost and the total carrying cost is equal among various lot size available.
The order quantity should be choose when the total ordering cost and the total carrying cost equal to each other
The formula to compute the economic order quantity is shown below:
a. The computation of the economic order quantity is shown below:

It is always be expressed in units
The formula to compute the ordering cost is

And, the formula to compute the carrying cost is

Hence, the given statement is true
Answer:
.b. It is one‐half as large as when n = 100.
Step-by-step explanation:
Given that a simple random sample of 100 batteries is selected from a process that produces batteries with a mean lifetime of 32 hours and a standard deviation of 3 hours.
i.e. s = 0.3
we obtain se of sample by dividing std devitation by the square root of sample size
i.e. s= 
when n =100 this = 0.3 and
when n =400 this equals 0.15
We find that when sample size is four times as large as original, std deviation becomes 1/2 of the original
Correction option is
.b. It is one‐half as large as when n = 100.
Answer:
96.9cm squared
Step-by-step explanation:
Answer:
f( - 2) = 23
Step-by-step explanation:

Consider the circle with center X, as shown in the figure.
Draw the diameter of the circle which is parallel to cherd AB, as shown in the figure.
Since the diameter and AB are parallel, then the line segment XC which bisects AB at C, will be perpendicular to AB.
SO triangle XCB is a right triangle. Thus the length of CX, by the Pythagorean theorem is

units.
Answer: 8 units
