Answer:
AUB={1,2,4,5,7,9}
ANB={ }
Explanation:
AUB means that you have to combine all the element in each set whereas ANB is the set of similar elements in set A and set B. As there is no same elements in set A and set B therefore ANB will be called as null set.
Answer: Suppose that the starting salaries for faculty at Super University ... distribution with mean of $80,000 and standard deviation of $10,000. ... chosen starting faculty member has a salary greater than $90,000? ... If a teacher is selected at random, find the probability that he or she makes more than $36,000.
Explanation:
What are you wanting from this.
By conservation of momentum,
(900 kg) (15.0 m/s) i + (750 kg) (20.0 m/s) j = (900 kg + 750 kg) v
where v is the velocity vector of the combined cars. Solve for v :
(13,500 i + 15,000 j) kg•m/s = (1650 kg) v
v ≈ (8.18 i + 9.09 j) m/s
Then the direction of v relative to East is θ such that
tan(θ) ≈ 9.09/8.18 ⇒ θ ≈ 48.0°
so the wreckages would move at approximately 48.0° north of east.
