E ∩ F = {}
Step-by-step explanation:
Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,
Given
E = {1, 2, 3}
F = {101, 102, 103, 104}
We have to find the intersection of both sets as indicated
So,
E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}
E ∩ F = {}
As there are no common elements in both sets the intersection will be an empty set

Answer:
Step-by-step explanation:
Let x represent the amount invested at 9%. Then 7000-x was invested at 4% and the interest earned was ...
9%·x +4%(7000-x) = 430
5%·x +280 = 430 . . . . . . . . . simplify
0.05x = 150 . . . . . . . . . . . subtract 280
x = 3000 . . . . . . . . . . divide by 0.05
$3000 was invested at 9%; $4000 was invested at 4%.
