10x6=60 so 180-60=120 and 120 divided by 8 is 15 so the answer is 15 hours

Dmitry_Shevchenko [17]

Answer:

a) 131/450

b) 1233/1276  

Step-by-step explanation:

P(bad) = P(1st batch)*P(bad 1st batch ) + P(2nd batch )*P(bad 2nd batch) + P(3rd batch )*P(bad 3rd batch)

p(bad) =(60/360)*(1/3) + (120/360)*(1/4 ) + (180/360)*(1/5)

= 43/180  

And that of  P(good )

= 1 - 43/180

= 137/180

a)

P(defective) = P(bad)*P(defective /bad) + P(good)*P(defective /good)

= (43/180)*(9/10) + (137/180)*(1/10)

= 131/450

b)

P(Bc I Dc ) = P(good)*P(not defective |good) / P(not defective)

= (137/180)*(1 - 1/10) / (1 - 131/450)

= 1233/1276

Last Week we drove to Detroit. At an Average Speed Of 50 Miles Per Hour, the trip Took 4 1/4 hours. How Far Was it?
Mkey [24]
212.5 miles

If the car is moving at 50 miles per hour, that means in 1 hour, it traveled 50 miles. In 2:100, 3:150, & 4:200. 1/4 of 50 is 12.5. So, when travelling for 4 1/4 hours, the vehicle traveled for 212.5 miles.
