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.

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.

Mika taught her sister the steps for dividing a decimal by a decimal. which instructions are correct? 1. multiply the divisor by a multiple of 10 to create an integer divisor. 2. multiply the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. multiply the dividend by a multiple of 10 to create an integer. 2. multiply the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the divisor by a multiple of 10 to create an integer divisor. 2. divide the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the dividend by a multiple of 10 to create an integer. 2. divide the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. huy
