The overhead reach distances of adult females are normally distributed with a mean of 200 cm and a standard deviation of 7.8 cm. a. find the probability that an individual distance is > 210.00 cm. b. find the probability that the mean for 25 randomly selected distances is > 197.80 cm. c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?

4. find the geometric mean of 4 and 12. 24 8

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
