AACE International CCP Exam With Confidence Using Practice Dumps

To calculate the mean unit cost, you add up all the unit costs and divide by the number of data points.

Mean Unit Cost=Sum of All Unit CostsNumber of Data Points\text{Mean Unit Cost} = \frac{\text{Sum of All Unit Costs}}{\text{Number of Data Points}}Mean Unit Cost=Number of Data PointsSum of All Unit Costs​

Adding the unit costs:

55.00+34.50+37.30+55.00+40.00+26.78+46.59+75.00+65.00=434.1755.00 + 34.50 + 37.30 + 55.00 + 40.00 + 26.78 + 46.59 + 75.00 + 65.00 = 434.1755.00+34.50+37.30+55.00+40.00+26.78+46.59+75.00+65.00=434.17

Number of data points: 9

Mean Unit Cost=434.179≈48.24\text{Mean Unit Cost} = \frac{434.17}{9} \approx 48.24Mean Unit Cost=9434.17​≈48.24

The closest match to the available options isB. $48.22.

You need to find the relative frequency of unit costs from Atlanta, GA.

Steps:

Identify the number of bids from Atlanta, GA:

8/31/05: 530 units at $55.00/unit

11/19/04: 308 units at $40.00/unit

1/26/05: 45 units at $26.78/unit

Total number of instances: 3

To calculate the volume of concrete required for a slab, the formula for volume in cubic feet is:

Volume=Length×Width×Depth\text{Volume} = \text{Length} \times \text{Width} \times \text{Depth}Volume=Length×Width×Depth

Given:

Length = 13.5 feet

Width = 10 feet

Depth = 6 inches (which is 0.5 feet)

Volume=13.5×10×0.5=67.5 cubic feet\text{Volume} = 13.5 \times 10 \times 0.5 = 67.5 \text{ cubic feet}Volume=13.5×10×0.5=67.5 cubic feet

To convert cubic feet to cubic yards (since 1 cubic yard = 27 cubic feet):

Cubic Yards=67.527=2.5 cubic yards\text{Cubic Yards} = \frac{67.5}{27} = 2.5 \text{ cubic yards}Cubic Yards=2767.5​=2.5 cubic yards

Upon review, there seems to be a mistake in the available options, as the calculation yields 2.5 cubic yards, which would suggest a correct answer is not listed. Given the options provided, I would selectD. 2.5 cubic yardsas the closest accurate calculation. However, if constrained to the given answers,B. 2.0 cubic yardsis incorrect by calculation standards.
