If v(x) represents the volume of water, in cubic inches, in a tank when the height of the water is x inches, give a practical interpretation of v^-1(10). a.)the volume of the water in the tank is 10 cubic inches.
b.)the volume of the water in the tank, in cubic inches, when the height is 10 inches.
c.) the height of the water in the tank is 10 inches.
d.)the height of the water in the tank, in inches, when the volume is 10 cubic inches.
e.)the volume of the water in the tank, in cubic inches, after 10 minutes.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
