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
The -4 will translate the graph of f(x) 4 units to the right.
Then the -2 before the x will stretch it vertically with factor 2, then reflect it in the y -axis.
Finally the + 5 will translate the graph 5 units vertically upwards
Answer:
FE
Step-by-step explanation:
The radius of a circle is the line segment from the centre of the circle to a point on the circle.
F is the centre of the circle, thus
FA, FE, FD, FC and FB are all radii of the circle

Step-by-step explanation:
La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.
f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz
El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.
T = t / n = 3/15 = 0,2 segundos
