Answer:
Option B is the right choice,congruent to are .
Step-by-step explanation:
If we look on to the diagram and the options we can sort out the angles on the basis of our requirement.
There are three sets arising from the angles.
[Corresponding angles]
The corresponding angles are the ones at the same location at each intersection.
[Vertically opposite angles]
And
[Alternate interior angles]
Now
[Corresponding angles]
[Vertically opposite angles]
[Vertically opposite angles]
So the correct pair from the options given is B which includes
Answer:
a) Figure attached
b)
c)
d)
Step-by-step explanation:
2 hr = 120 min
2hr 20 min = 120+20 = 140 min
Let X the random variable that represent "flight time". And we know that the distribution of X is given by:
For this case the density function for A is given by:
And for other case
Part a
For this case we can see the figure attached. We see that the probability density function is defined between 120 and 140 minutes.
Part b
The arrival time is 2hr 5 min = 125 min. So then 5 minutes leate means 130 min
For this case we want to find this probability:
And we can use the cumulative distribution function for X given by:
And if we use this formula we got:
Part c
For this case more than 10 minutes late means 125 +10 = 135 min or more, so we want this probability:
And using the complement rule we have:
Part d
The expected value for the uniform distribution is given by:
Answer:
1/343
Step-by-step explanation:
If you multiply 1/7*1/7*1/7 (1/7^3) then you would get 1/343.
