Given that a machine produces defective parts with three different probabilities depending on its state of repair.
condition Good order Wearing down Needs main Total
Prob 0.8 0.1 0.1 1
Defective 0.02 0.1 0.3
Joint prob 0.016 0.01 0.03 0.056
a) 0.016
b) total = 0.056
c) If not defective from needs maintenance
Prob for not defective =
From machine that needs maintenance = 0.07
So reqd prob =

10%
Step-by-step explanation:
Given: CP of lemon is $600.
3/4 of lemon sold at 20% loss
Remaining lemon at 20% gain.
Considering the quantity of lemon remain constant.
Cost price of 3/4 of lemon=
As given, 3/4 of lemon sold at 20% loss.
∴ Selling price of
Selling price=
Hence, selling price of 3/4 lemon is $360.
Now, the cost price of remaining lemon
∴ The cost price of
As given, remaining
∴ Selling price of
Selling price of
Hence, selling price of 1/4 lemon is $180
Loss\profit percent=
∴ Loss\profit percent=
Hence, the loss percentage is 10%
Answer: Last Option
Step-by-step explanation:
The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.
If m represents the number of months elapsed then the equation for the height of the plant of species A is:
For species B the initial height is 10 cm and it grows 8 cm each month
If m represents the number of months elapsed then the equation for the height of the plant of species B is:
Finally, the system of equations is:
The answer is the last option
