We are building a foundation for a utility building. The building will be 24' X 16'. The footing will be
16" wide and will be poured to a depth of 8". The
foundation wall will be 32" tall. How much
concrete is required for the footing? How many
bricks do we need for the outer wythe? How
many CMU's do we need for the inside wythe?
Extra Credit: How much sand and mortar do we
need?

How do you find the circumfrance of a circle?

What is the ordered pair of m’ after point m (5, 6) is rotated 90° counterclockwise?

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
