In a previous problem, you calculated how much energy was needed to accelerate a 2,100-kg tesla model s from 0 to 100 km/hr, and found that the value was not dependent on how long it took. however, the power is! unlike gas engines, electric engines supply equal power regardless of their speed. a tesla model s is capable of generating 345 kw of power. assuming no losses of energy to friction, what is the minimum length of time it takes to accelerate a tesla model s from rest to 100 km/hr?

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
