The area of the rectangle is 2x(3x - 5)
From calculus, to determine the maxima or minima of the graph, get the derivative of the equation and equate to zero. So, we derive first the equation of the graph and equate to zero.
C = 0.25x² - 80x + 30000
dC/dx = 0 = 0.5x - 80 + 0
0.5x = 80
x = 80/0.5
x = 160 units
The minimum cost (although not asked) is:
C = 0.25(160)² - 80(160) + 30000
C = $23,600
The answer is 160 units.
The distributive property combines like terms.
Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean = 
<em> , where </em>
= population standard deviation , n= sample size.
Given : n= 45 , 
grams
The e standard error of the sample mean 
Hence, the standard error of the sample mean = 0.44
