The weights of passengers and their luggage are normally distributed with a mean of 192 pounds with a standard deviation of 30 pounds. Oceanic Airlines flight 815 with 100 passengers has fuel sufficient to make it to its destination if the total weight of the passengers and their luggage does not exceed 10 tons. What is the likelihood that they have sufficient fuel

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
