Let Bi = {x ∈ ℝ|0 ≤ x ≤ i} for each integer i = 1, 2, 3, 4. (a) Find B1 ∪ B2 ∪ B3 ∪ B4. (Enter your answer using interval notation.) (b) Find B1 ∩ B2 ∩ B3 ∩ B4. (Enter your answer using interval notation.) (c) Are B1, B2, B3, and B4 mutually disjoint? Explain. Yes, because no two of the sets B1, B2, B3, B4 have any elements in common. Yes, because the union of the sets B1, B2, B3, B4 is empty. Yes, because the intersection of the sets B1, B2, B3, B4 is empty. No, because no two of the sets B1, B2, B3, B4 are disjoint. No, because the sets B1, B2, B3, B4 are disjoint.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
