Answer:
260 machines for minimum cost.
Step-by-step explanation:
c(x) = 0.3x^2 - 156x + 26.657
Finding the derivative:
c'(x) = 0.6x - 156
0.6x - 156 = 0 for maxm/minm cost.
x = 156 / 0.6
= 260
The second derivative is positive (0.6) so this is a minimum.
Answer: the equation is 6+5x=3x+10.
Step-by-step explanation:
to find the number
add 5x+3x
then add 10+6
8x=16
divide by 2 each side.
x=2
The equation is: 3x^3 = 4x + 8
The form is ax^2 + bx + c = 0
Rewrite the given equation to equal 0:
Subtract 3x^2 from both sides to get:-3x^2 + 4x + 8 = 0
Now give each letter their value:
a = -3, b = 4, c = 8
With 
, we have identical PDFs

, and 0 otherwise, where
Since 
are independent, the joint PDF is
for points 
in the unit square, and 0 otherwise.
1. The distribution is continuous, so 
.
2. 
is the region in the 
plane contained within the unit square and above the line 
. This region is empty, because this line lies above the square altogether, so 
.
3. 
is the region in the same square below the line 
. So we have
