Suppose Celine wants to choose a box that maximizes the amount of cereal it can hold.

Volume of Box 1: 3x5
Volume of Box 2: 4x5 – x4

If Celine decides the width of the cereal boxes will be greater than 1, which box will hold more cereal? Explain.

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
