Joe is lending Frank $500 and Frank has 4 years to pay it back. Joe is charging 6% interest. Frank has determined how much interest he'll pay over the 4 years.
He sets up the formula, interest (i) = loan amount (l) x rate (r) x time (t).
What is $120?

Many samples are taken from the same larger population and measured. A researcher finds that the means of the individual samples are systematically higher than the population mean. Accordingly, this is what the researcher would most likely conclude
What are either the sampling method is biased or the population mean has changed.

A zoologist studying reptiles observes that two populations of iguanas—the black-striped and red-striped varieties—have the same mean tail length. However, while both have normal distributions, the population of red-striped iguanas has a smaller standard deviation than the population of black-striped iguanas. If plotted, this is how the curves for the tail lengths of both populations compare
What is the curve for the black-striped iguanas would be shorter because it has a larger standard deviation?

A child jumps on a trampoline and rises at a rate of 10 ft/min. The child’s mother is watching from the patio 40 ft away. How fast, in rad/sec, is the angle of elevation between the trampoline and the mother’s line of sight of her child increasing when the child is 30 ft in the air?
1/375 rad/sec
