Answer:
(c) $72
Step-by-step explanation:
Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...
12 × 12 = 144
tiles will be needed to cover the area.
The cost of 144 tiles at $0.50 each is ...
(144)($0.50) = $72.00
The probability of profiting $5.2 million is 5% = 0.05
The probability of profiting $0.9 million is 50% = 0.5
The probability of breaking even, meaning no profit gain, is 45% = 0.45
Expected profit values of the CD is given by
(0.05×5.2) + (0.5×0.9) + (0.45×0) = 0.26+0.45+0 = 0.71 million
Only thing I can tell you is to use a corner to a piece of paper. The corner is 90 degrees. It's acute if the corner is bigger than the angle. Obtuse if its smaller.
The Solution is 5.68 x 10^5
