No, he has not watched the whole movie. The answer would be D. he only has 2/15 to watch.
Hope I helped!

Answer:
The required null and alternative hypothesis are and .
Step-by-step explanation:
Consider the provided information.
A person who claims to be psychic says that the probability, p, that he can correctly predict the outcome of the value of a card drawn from a deck of cards in another room is greater than 1/13, the value that applies with random guessing.
To test this claim we need to use the data from an experiment in which he predicts the outcomes for n trials.
Since, alternative hypothesis represents the effect and null hypothesis represents no effect,
Therefore null hypothesis will be: The person can predict outcome of the value of a card drawn in another room 1/13.
The alternative hypothesis will be the person can predict outcome of the value of card is greater than 1/3.
Hence, the required null and alternative hypothesis are and .
Distance=speed*time
distance traveled by plane A after 40 minutes:
distance=570×40/60=380 miles
Distance traveled by B after 40 minutes
distance=20/60×585=195 miles
Thus the distance between them will be given using cosine law:
c^2=a^2+b^2-2ab Cos C
thus we shall have:
c^2=380^2+195^2-2*380*195*cos22
c^2=45016.35275
c=212.171 miles
Thus the distance between them after 40 minutes is 212.171 miles
The correct answer is the last one: 675 pi cm3.
