The asteroid belt is the circumstellar disc in the solar system, located roughly between the orbits of mars and jupiter, that is occupied by many irregularly shaped bodies called asteroids. the inner edge of zone 2 of the asteroid belt starts right at the outer edge of zone 1 and is located at a radius of about 2.5 au. the outer edge of zone 2 of the belt is located at a radius of about 2.82 au, with zone 3 starting right beyond. a) what is the flux from the sun (w/m²) at the outer edge of zone 1 and at the inner edge of zone 3 of the asteroid belt? b) if there was a dyson sphere at either radius, how much energy would it receive from the sun?

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?
