To answer this item, we take the differential of the equation and equate to zero.
C(x) = 0.8x² - 256x + 25939
Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160.
Thus, the number of machine to be made in order to minimize the cost should be 160.
Answer:
Total periodic pension costs (TPPC) is equal to the contributions plus change in the pension liability during the year. Each period, the periodic pension cost is recognized in profit or loss (P&L) and/or in other comprehensive income (OCI).
596 x 25% = 149
This implies 149 persons over the age of 65 voted.
I hope this helps.
The sampling technique used when A scientist chooses twenty people at random from each class is stratified sampling.
<h3>What is
stratified sampling?</h3>
Stratified sampling can be described as the type of sampling method whereby the total population is been divided into smaller groups or strata.
This usually done to complete the sampling process, hence The sampling technique used when A scientist chooses twenty people at random from each class is stratified sampling.
