Answer:
0.52474, 0.47526
Step-by-step explanation:
given that based in the U.S. Census Bureau’s American Community Survey of 2017, 12.9% of the U.S. population was foreign-born.
The U.S. Census Bureau uses the term foreign-born to refer to anyone who is not a U.S. citizen at birth.
Hence for a randomly selected citizen to be foreign born has constant probability 12.9% since each person is independent of the other and there are only two outcomes.
For the sample of 5 students, X = foreign born is binomial (5, 0.129)
1) the probability that none of the students are foreign-born (x=0)
=
2 p(x>=1) (that at least one is foreign-born)
=
By direct computation, arctan(0) = 0, arccot(0) = pi/2, arctan(1) = arccot(1) = pi/4.
Let a = arctan(sqrt(2)). Then cot(3*pi/2 - a) = cot(pi/2 - a) = tan(a) = sqrt(2), so arccot(sqrt(2)) = 3*pi/2 - a. Therefore, arctan(sqrt(2)) + arccot(sqrt(2)) = 3*pi/2.
Similarly, arctan(sqrt(3)) + arccot(sqrt(3)) = 3*pi/2.
So the answer is 0 + pi/2 + pi/4 + pi/4 + 3*pi/2 + 3*pi/2 = 4*pi.
Infinite solutions they are a set of equations that express a set of quantities
Answer:
