The branching ratio for the decay mode D+→K*0μ+ν has been measured with two methods. The first uses D0→K-μ+ν for normalization, and yields the result B(D+→K*0μ+ν)=(3.25±0.71±0.75)%. From this method we also obtain the direct measurement Γ(D+→K*0μ+ν)/Γ(D0→K-μ+ν)=0.43±0.09±0.09. The second method uses the mode D+→K-π+π+ for normalization and yields B(D+→K*0μ+ν)=(4.18±0.66±0.96)%. Combining the results of the two methods yields B(D+→K*0μ+ν)=(3.57±0.96)%.
