91 divided by 7 is 13. so he can paint 13 in 1 week. 13 x 4 equals 52 so he can paint 52 portraits in 4 weeks.
<span> 6.022 x 1023 i think thats how much
</span>
Median:15 1,11,14,15,31,37,47
Mean:22 (1+11+14+15+31+37+47)/7=22
The end of the bar should end in the exact middle of 8 and 10.
Hope this helps! :)
