Answer:
The minimum cost per unit is obtained for an order of 8 units.
Step-by-step explanation:
Since the total cost is modeled by;
C(x)=5x²+320
Then;
1 unit costs; C(x)=5(1)²+320 = 325
cost per unit 325/1 = 325
8 units costs; C(x)=5(8)²+320 = 640
cost per unit = 640/8 = 80
80 units costs; C(x)=5(80)²+320 = 32320
Cost per unit = 32320/80 = 404
The minimum cost per unit is obtained for an order of 8 units.
30% of number A means

similarly, 40% of number B means

These must be equal, so we have

Multiply both sides by 10 to get

So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.
Answer:
D 6
Step-by-step explanation:
substitute in 1 for x
2(1)= 2
2+4= 6
y=6 when x=1
Answer:
96, 64, 42.6 or (
)
Step-by-step explanation:
Results and Discussion are definitely very relevant for examining an observational study - they contain the core of the study, so they will definitely be considered when evaluated.
So we choose between "Bias" and "Introduction".
I think that the correct answer is "Introduction" -as it doesn't include any new information about the study, and only summarizes previous work.
