The amounts a soft drink machine is designed to dispense for each drink are normally distributed, with a mean of 11.711.7 fluid ounces and a standard deviation of 0.20.2 fluid ounce. A drink is randomly selected. Find the probability that the drink is between 11.511.5 and 11.611.6 fluid ounces.
1 answer:
Answer: 0.1499
Step-by-step explanation:
Given : The amounts a soft drink machine is designed to dispense for each drink are normally distributed, with mean
Standard deviation :
z-score :
For X = 11.5
For X = 11.6
Now, the probability that the drink is between 11.511.5 and 11.611.6 fluid ounces will be :-
Hence, the probability that the drink is between 11.511.5 and 11.611.6 fluid ounces =0.1499

Answer: The volume of the tent is 293.33 ft.
Explanation: 11 x 10 x 8 = 880
The formula for the volume of a right rectangular pyramid is lwh/3.
880/3 = approximately 293.33
4% of $8000 is $320 x 9 = $2880 The answer is $2880
0.5 x 4 = 2 feet / 2 feet in 4 seconds 15 - 2 = 13 New depth: 13 feet 0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds 13 - 1.2 = 11.8 New depth: 11.8 feet
