For part of the first year of a dog's life, its growth can be approximated using a linear function. Emilie has two puppies:
a Border collie and a younger Saint
Bernard. During a 4-week period,
the Border collie grows from
13.4 kg to 17 kg, while the Saint
Bernard
grows from 6 kg to 12.4 kg.
Suppose each dog grows at a
constant rate. Will the dogs
ever have the same mass? If
so, approximately what is
the mass?

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Which inequality has a dashed boundary line when graphed ?

Abag contains 3 red marbles, 2 blue marbles, and 2 green marbles. one marble is picked, then another marble. assume that the selections are made with replacement. a) find the probability of picking two red marbles with replacement. b) find the probability of picking a red marble and a blue marble. assume the selections are made without replacement. c) find the probability of picking two red marbles without replacement. d) find the probability of picking a red marble and a blue marble without replacement.
