Question

1) The line plot shows the weight gain, in pounds, of several dogs seen on Monday by a veterinarian at the animal clinic. How many dogs gained fewer than 3 lb? The 1st picture is for the 1st question

2) Which has data value the highest frequency? The 2nd pic is for the 2nd question

1/16

3/16

3/8

5/8

Answer 1

1. If including the gained-three-pound-guy, then it is four because we have to count the dots on 0.5, 1.5, 2, and 3.
2. Highest frequency basically just means what is the most often occuring number (mode) in fancy language. The answers we can rule out are 5/8, 3/8, and 3/16. The answer is 1/16 because it has the most. :) Hope I helped 

Answer 2

I believe the answer is 3.
