Miriam took a survey, asking each family in her neighborhood how many pets they have. She made a graph showing the results: [asy] size(5.5cm); draw((0,30)--(0,0)--(41,0)); for(int i=1; i<7; i+=1) {draw((0.6,5i)--(-0.6,5i)); draw((0.6,5i)--(41,5i),black+0.5+ dashed); }; path a=(3,0)--(3,30)--(9,30)--(9,0)--cyc le; path b=(9,0)--(9,15)--(15,15)--(15,0)--c ycle; path c=(15,0)--(15,15)--(21,15)--(21,0)- -cycle; path d=(21,0)--(21,30)--(27,30)--(27,0)- -cycle; path e=(27,0)--(27,5)--(33,5)--(33,0)--c ycle; path f=(33,0)--(33,5)--(39,5)--(39,0)--c ycle; fill(a, gray); fill(b, gray); fill(c, gray); fill(d, gray); fill(e, gray); fill(f, gray); draw(a); draw(b); draw(c); draw(d); draw(e); draw(f); label(rotate(-45)scale(0.8)"0 pets",(5,-1),SE); label(rotate(-45)scale(0.8)"1 pet",(11,-1),SE); label(rotate(-45)scale(0.8)"2 pets",(17,-1),SE); label(rotate(-45)scale(0.8)"3 pets",(23,-1),SE); label(rotate(-45)scale(0.8)"4 pets",(29,-1),SE); label(rotate(-45)scale(0.8)"5 pets",(35,-1),SE); label(scale(0.8)"1",(-0.6,5),W); label(scale(0.8)"2",(-0.6,10),W); label(scale(0.8)"3",(-0.6,15),W); label(scale(0.8)"4",(-0.6,20),W); label(scale(0.8)"5",(-0.6,25),W); label(scale(0.8)"6",(-0.6,30),W); label(scale(0.8)rotate(90)"Number of families",(-3.5,15),W); [/asy] What is the average number of pets per family?
