  Dark matter seems to account for flat velocity curves in spiral galaxies,
with further evidence for dark matter from observations of the colliding
"bullet cluster" galaxies 1E0657-56. However, the baryonic Tully-Fisher
relation and the mass discrepancy-acceleration relation have been cited
(arXiv:1112.3960) as "challenges for the LambdaCDM model." MOND (MOdified
Newtonian Dynamics), a modified law of gravity,is invoked in arXiv:1112.3960 to
account for those relations.
  This note shows that the HLSS model in arXiv:1301.0304, employing the
holographic principle within the standard LambdaCDM paradigm, readily accounts
for the MOND acceleration, the baryonic Tully-Fisher relation, and the mass
discrepancy-acceleration relation. After first posting this note, I learned
that Man Ho Chan (arXiv:1310.6801) previously reached the same conclusion using
a dark matter based analysis independent of the holographic approach used in
this paper. These results indicate that the MOND hypothesis is unnecessary.
