Find the surface area or the approximate surface area of each figure,
96 square inchios
16 square inches
94 square indies
75 square inches
3 square pyramid with a base length and
slant height of 5 inches
a rectangular prism with a length of 5 inches,
8 width of 4 inches, and a height of 3 inches
3 cube where the length of each edge is
4 inches
a triangular prism where the area of each
base is about 20 square inches, the length
of each side of the base is 6 inches, and
the height of the prism is 2 inches

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
