Answer: 0.2119
Step-by-step explanation:
We assume that the random variable X is normally distributed.
Given : Population mean : 
Standard deviation : 
Z-score : 
Then, z-score corresponds to 116

By using the standard normal distribution table for z , we have


Hence, the required probability = 0.2119
Answer:
9 minutes
Step-by-step explanation:
12 divided by 1.5 is 9.
(a) x = 0.36--, 100x = 36.36--, 100x-x = 36, x = 36/99 = 4/11
(b) x = 0.36-, 100x = 36.6-, 100x-x = 36.3, x= 363/990=11/30
(c) 36/100 = 9/25
