he number of undergraduates at Colby College is approximately 1800; the number at Penn State University is approximately 39,000. Suppose that at both schools an SRS of about 3% of the undergraduates is taken. In that case, we can conclude that:

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180
