Answer:
C
Step-by-step explanation:
Zscore = - 0.18 ; Z = 1.23
To find the percentage :
P(Z< 1.23) - P(Z < - 0.18)
Using the Z probability calculator :
P(Z < - 0.18) = 0.42858
P(Z < 1.23) = 0.89065
0.89065 - 0.42858
= 0.46207
= 46.2%
Suppose that U (the universal set), A and B are sets, given as shown below. U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10), A = {1, 4, 6, 8

Answer:
A' U B = {2,3,5,7,8}
A' n B' = {2,3,7}
A n B' = {4,6,8,10}
Step-by-step explanation:
In our problem, the universal set is:
U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
We also have:
A = {1, 4, 6, 8, 9, 10}
B = {1,5,9}.
The complement of a set is a set made by every element that is contained in the universal set and is not contained in the set. So
A' = {2,3,5,7}
B' = {2,3,4,6,7,8,10}
The union of two sets is the set that contains every element that is in at least one of those sets: So
A' U B = {2,3,5,7,8}
The intersection of two sets is the set that contains every element that is in both of those sets. So:
A' n B' = {2,3,7}
A n B' = {4,6,8,10}

Answer:
X=10
AB=12
BC=27
Solution: solving the algebraic equation we get x=10, then plug in x for each of the equations separately

Answer:
Using Green's theorem we have:
int F.dr =
int int d/dx ((y^2-x^2)/(x^2+y^2)^2) - d/dy (2xy/(x^2+y^2)^2) =
(2x^3 - 6xy^2) / (x^2+y^2)^3 - (2x^3 - 6xy^2) / (x^2+y^2)^3 =
0
Therefore:
int F.dr = 0
