The set is linearly dependent.
To explicitly prove this, we need to show there is at least one choice of constants
such that

or equivalently,

which is the same as solving the system of equations

From the first and last equations, we have
and
. Substituting these into the second equation leaves us with
, and so the overall solution set is

for which there are infinitely many not-all-zero solutions.
I believe it’s 8^3 I’m sorry if it’s wrong!!!!
Use A' for A complement, etc. and n = intersection ∩.
n(A' n B')
=n(A u B)' by the de Morgan's law
=nU-n(nA+nB-n(AnB)) n(A u B) = nA + nB - n(AnB) and nX'=nU-nX
=400-(135+80-60)
=400-155
=245
Asumming that 3/5 is the number of miles Jennifer has gone in 1/5 of an hour. We can take 60 (# of minutes in an hour) divided by 5, which equals 12. So 3/5 is 36 minutes. to figure out how many 1/5 are in 8 miles we would take 8 times 5 which is 40. We would then take 3 times 8, which is 24. 40 - 24 = 16. So 16 times 5 = 80 minutes. 80 divided by 60 (# of minutes in an hour) is 1 hour and 20 minutes. So it takes Jennifer 1 hour and 20 minutes to travel 8 miles.
