The entire output of a factory is produced on three machines. The three machines account for 20%, 30%, and 50% of the output, re
Sliva [168]

Answer: 0.20833

Step-by-step explanation:

This is a case of inverse probability.

We first determine the probability that an item is defective generally.

To do this we sum the possible options of having the item produced from the first machine and is defective or having the item produced by the second machine and is defective or having the item produced by the third machine and is defective.

Mathematically,this becomes :

(0.2 * 0.05) + (0.3 * 0.03) + (0.5 * 0.01)

0.01 + 0.009 + 0.005 = 0.024.

Probability an item is defective in general = 0.024

Probability a third machine produces a defective item = 0.5 * 0.01 = 0.005.

Hence, given that the item is defective, the probability that it was produced by the third machine becomes:

= (probability of the item being produced from the third machine and is defective) / (probability of the item being defective in general)

= 0.005/0.024

= 0.20833.

The revenue each season from tickets at the theme part is represented by t(x) = 3x. The cost to pay the employees each season is
Triss [41]

Answer: The profit after 5 seasons is $239.94.

Step-by-step explanation:

Since we have given that

Revenue function is given by

t(x)=3^x

Cost function is given by

r(x)=1.25^x

So, We need to find the total profit:

As we know the formula for profit:

Profit = Revenue - Cost

P(x)=t(x)-r(x)\\\\P(x)=3^x-1.25^x

We need to evaluate the profit after five seasons:

P(5)=3^5-1.25^5\\\\P(5)=\$239.94

Hence, the profit after 5 seasons is $239.94.
