- A florist offers three sizes of flower arrangements containing roses, daisies, and chrysanthemums. Each small arrangement contains one rose, three daisies, and three chrysanthemums. Each medium arrangement contains two roses, four daisies, and six chrysanthemums. Each large arrangement contains four roses, eight daisies, and six chrysanthemums. One day, the florist noted that she used a total of 24 roses, 50 daisies, and 48 chrysanthemums in filling orders for these three types of arrangements. How many arrangements of each type did she make?arrow_forwardThe average monthly residential gas bill for Black Hills Energy customers in Cheyenne, Wyoming is (Wyoming Public Service Commission website).

- A table has 6 rows and 6 columns. The 36 entries are pairs of faces of dice, one blue and one white, so each pair corresponds to one of the 36 possible rolls of two dice. Faces are depicted as colored squares, either blue or white, marked with 1, 2, 3, 4, 5, or 6 dots (pips). Column numbers correspond to values of the blue die in each pair: all pairs in column 1 have blue 1, all pairs in column 2 have blue 2, and so on. Row numbers correspond to values of the white die in each pair: all pairs in row 1 have white 1, all pairs in row 2 have white 2, and so on. For example, the top left pair at column 1, row 1 is blue 1, white 1. The column 1, row 2 pair is blue 1, white 2. The column 2, row 1 pair is blue 2, white 1, and so on. The bottom right pair is blue 6, white 6. A.
