For a science experiment, Jason measures the time it takes for different liquids to flow out of a container with a small hole at the bottom. He displays his results for one particular liquid in a table as shown. Let y represent the height of the liquid above the hole and x represent the time in seconds it takes for the container to empty. The equation that represents the relationship of x and y is

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.
