A foreman for an injection-molding firm admits that on 55% of his shifts, he forgets to shut off the injection machine on his li
motikmotik

Answer:

0.8594

Step-by-step explanation:

Let a denote the event of forgetting to shut off machine and b be the event of being defective.

-A foreman forgets to shut off machine 55% of the time.

-If he forgets, 15% of molds are defective.

-If he does not, 3% of molds are defective.

#The probability that he forgot to shut off the machine is calculated as:

P(a \ and \ b)=0.55\times 0.15\\\\=0.0825\\\\

P(a and ~b)=0.55(1-0.15)=0.4675

P(~a and b) = (1-0.55)*0.03=0.0135

P(~a and ~b) = (1-0.55)*(1-0.03)=0.4365

#Conditional probability is defined as:

P(a|b)=\frac{P(a \ and\  b)}{P(a)}\\\\=\frac{P(a \ and \ b)}{[(P(a \ and \ b)+P(\~a \ and \ b)}\\\\\\=\frac{0.0825}{0.0825+0.0135}\\\\\\=0.8594

Hence,  the probability that the foreman forgot to shut off the machine the previous night is 0.8594

Need help with 3 and 4 consumer math plz
ratelena [41]

Answer:

3) C) $792.50

4) D) $707.50

Step-by-step explanation:

3) Home price = $ 253,600

Mortgage rate = 3.75% APR

Therefore, monthly rate = 3.75% divide by 12

= 0.0375/12

= 0.003125

1st month interest = principle * 0.003125

= 253600*0.003125

=$792.50

3) Answer: $792.50

4) You paid $1500

The first monthly interest = $792.50

Principal paid in the first month = 1500 - 792.50

= $707.50

Answer: D) $707.50

Thank you.
