<span>3 black ribbons and 12 green ribbons
so P(</span><span>Lila selects a black ribbon)=3/(3+12)
=1/5
</span>2 black ribbons and 12 green ribbons left
P(<span>Jessica selects a green ribbon)=12/(12+2)
</span>=6/7
so P(<span>Lila selects a black ribbon and Jessica selects a green ribbon)
</span>=1/5*6/7
=6/35
ans is D
Answer:
the real answer is -1/3
Step-by-step explanation:
6lyl +6=4 subtract 6 from both sides
6lyl =-2 divide both sides by 6
lyl = -1/3
But absolute value is always a positive quantity, so this is impossible.....
Answer:
hence the required minimum production level is 12units
Step-by-step explanation:
Given the cost function expressed as c(x) = x^3 - 24x^2 + 30,000x
The average cost function will be c(x)/x
Dividing the cost function through by x
Average cost function = c(x)/x = x³/x - 24x²/x + 30,000x/x
Average cost function = x²-24x + 30,000
A(x) = x²-24x + 30,000
If the average cost is minimized, hence dA/dx = 0
dA/dx = 2x - 24
0 = 2x - 24
-2x = -24
Divide both sides by -2
-2x/-2 = -24/-2
x = 12
For the second deriviative
d²A/dx² = 2 which is greater than zero
Hence a production level that will minimize the average cost per item of making x items is 12
