Answer : 0.0129
Step-by-step explanation:
Given : Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is years and standard deviation is years.
Sample size :
Let X be the random variable that represents the age of fleets.
We assume that the ages of the fleets of the 10 largest U.S. commercial passenger carriers are normally distributed.
For z-score,
For x=14
By using the standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be :-
Hence, the required probability = 0.0129
Answer:
Step-by-step explanation:
Table 1: Add 7 to each output too get the answer for each input. Example output 1 +7 =Output 8
Table 2: Multiply each input by 6 to get the answer for each output. Example input 4 x 6=output 24
Table 3: Add 10 to each input to get output. Example 10+10=20 output
The area is 452.39
Hint : If you know the radius of a circle , you can use it to find the area of what that circle . Just plug that value into the formula for the area of a circle and solve .
I hope that's help !
750,000 you round the 4 up because of the 5 next to it. Id the number to the right of it is 5 or higher you round up :)
