Answer: 0.7887
Step-by-step explanation:
Let x be the random variable that represents the diameters of the corks .
Given : The first produces corks with diameters that are normally distributed with mean 3 cm and standard deviation 0.08 cm.
i.e. 
Acceptable corks have diameters between 2.9 cm and 3.1 cm.
Then, the probability that the first machine produces an acceptable cork will be :_

∴ The probability that the first machine produces an acceptable cork= 0.7887
-10 F
Subtract 6 from 8 three times for each hour, and you get -10 F.
