Which of the following functions If entered in F4 and copled down through F6 will compute the weighted average across the row for all three sets of four values? - L.e. what formula(s) can be entered in F4 and copied down such that - F4=0.2800+0.3600+0.4300+0.1600 - F5=0.2600+0.3800+0.4200+0.1100 - F6=0.2400+0.3200+0.4700+0.1100 Select one or more: =SUMPRODUCT(B2:E2,B4:E4)=SUMPRODUCT(B2:E2,$B$4:$E$4)=SUMPRODUCT($B$2:$E$2,B4:E4)=SUMPRODUCT(SB2:$E2,BS4:E$4)=SUMPRODUCT(B$2:E$2,B4:E4)==SUMPRODUCT(SB2:$E2,B4:E4)
