This is a geometric series
r = 4
a1 = 0.25
n = 5
Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
Two eventis are independent if knowledge about the first doesn't change your expectation about the second.
a) Independent: After you know that the first die showed 4, you stille expect all 6 numbers from the second. So, the fact that the first die showed 4 doesn't change your expectation about the second die: it can still show numbers from 1 to 6 with probability 1/6 each.
b) Independent: It's just the same as before. After you know that the first coin landed on heads, you still expect the second coin to land on heads or tails with probability 1/2 each. Knowledge about the first coin changed nothing about your expectation about the second coin.
a) Dependent: In this case, there is a cause-effect relation, so the events are dependent: knowing that a person is short-sighted makes you almost sure that he/she will wear glasses. So, knowledge about being short sighted changed your expectation about wearing glasses.
P = 3x + 0.5x + 9 - 3.4x - 25
P = 0.1x - 16
answer
