The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives
20.8
20.820, point, 8 years; the standard deviation is

Step-by-step explanation:

Let n be the maximum number of packages, that Shawn can carry with himself in the elevator if he is the only passenger.

Since each package weighs 5 pounds and Shawn weighs 100 pounds.

Total weight = Shawn's weight + (Weight of each package ) x (Number of packages)

= 100+5n

Since , the elevator can carry a maximum of 340 pounds at a time , then

Subtract 100 from both sides , we get

Divide both sides by 5 , we get

So , the inequality shows the maximum number of packages, n, that Shawn can carry with himself in the elevator if he is the only passenger is .
