SpletThe arithmetic mean of 100 observations is 24. So sum of all observations = 24*100 = 2400 Now, 6 is added to each of the observations, so the sum = 2400 + 100*6 = 3000 Then, each of them is multiplied by 2.5. So, the new sum of all observations = 3000*2.5 =7500 Hence new mean - 7500/100 = 75 So the correct answer is option B. SpletDuring a 24 h period of continuous minisodar observations, it was established that the mean kinetic energy density dominated in the surface atmospheric layer at altitudes below ~50 m. At altitudes from 50 to 100 m, the relative contributions of the mean and turbulent wind kinetic energy densities depended on the time of the day and the sounding ...
