Step-by-step explanation:
Answer:
7, 14, 21, 28, 35
Step-by-step explanation:
Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130
-----------------------------------------
S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)
-----------------------------------------
32.5+W=130
W=97.5
-----------------------------------------
Answer:
a) 0.3889
b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:

The probability of finding a value of X between c and d is:

The mean and the standard deviation are, respectively:


A random variable follows the continuous uniform distribution between 160 and 340.
This means that 
a)

b)

c)

d)


The mean is 250 and the standard deviation is 51.96.
