Suppose that an airplane is asked to stay in a holding pattern near an airport. the distance of the plane to the airport is described by the following. =dt+14978sinπ6t in this equation, dt is the distance of the plane to the airport (in miles), and t is the time (in minutes) after the plane enters the holding pattern. during the first 12 minutes after the plane enters the holding pattern, when will the plane be 190 miles from the airport? do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a minute. (if there is more than one answer, enter additional answers with the "or" button.)

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
