Answer:
Vertical distance between dolphin and the bird is 7.9 meters.
Step-by-step explanation:
Eva sees a Dolphin at the distance 3.2 meters below the sea level.
At the same time she sees a bird meters above the sea level.
Therefore, vertical distance between the dolphin and the bird = Distance of dolphin below the sea level + Distance of the bird above the sea level

Step-by-step explanation:
Given that according to a certain news poll, 71% agreed that it should be the government's responsibility to provide a decent standard of living for the elderly,
Let A be the event that it should be the government's responsibility to provide a decent standard of living for the elderly, and B the event that it would be a good idea to invest part of their Social Security taxes on their own
P(B) = 41%=0.41
A and B are independent
Hence P(both)=
the probability that a person agreed with both propositions
= Probability for both A and B
= P(A) P(B) since A and B are independent
= 0.3157
