Answer:
For Sarah's dogs, we have:
Morning:
39, 21, 12, 27, 23, 19, 19, 31, 36, 25
if the ranges are:
A) 10 pounds to 19 pounds: here we have the dog of 12, and two dogs of 19.
B) 20 to 29: one of 21 pounds, one of 27, one of 23 and one of 25, so here we have 4 dogs.
C) 30 to 39. here we have the left 3 dogs.
then the table is:
[tex]\left[\begin{array}{ccc}range&dogs\\10to19&3\\20to29&4\\30to39&3\end{array}\right][/tex]
For the afternoon, the weights of the dogs are:
15, 51, 8, 16, 43, 34, 27, 11, 8, 39
So the ranges:
0 to 9: here we have two dogs of 8.
10 to 19: 3 dogs, 15, 16 and 11.
20 to 29: 1 dog of 27
30 to 39: 2 dogs of 34 and 39
40 to 49: one dog of 43
50 to 59: one dog of 51.
the table is:
[tex]\left[\begin{array}{ccc}range&dogs\\0to9&2\\10to19&3\\20to29&1\\30to39&2\\40to49&1\\50to59&1\end{array}\right][/tex]
