For car speeds the mean speed record it was 77.83 mph with a standard deviation of 5.27 mph to see how many cars are speeding john subtract 37 mph from all speeds

1. what is the mean and standard deviation now what does this tell us about the speed of the cars

2. his friend in berlin wants to study the speed so john convert all the original miles per hour readings to kilometers per hour by multiplying or speeds by 1.609 (km per mile) what is the mean and standard deviation now

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
