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

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.

Select all expressions that are equivalent to 2(3x + 7y). question 1 options: 6x + 14y 6x + 7y 1(6x + 14y)

Marking brainliest rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.
