4. the company is building a scale model of the theater’s main show tank for an investor's presentation. each dimension will be made one eight of the original dimension to accommodate the mock-up in the presentation room. what is the volume of the smaller mock-up tank?

5. using the information from #4, answer the following question by filling in the blank: the volume of the original main show tank is % of the mock-up of the tank.

4) Volume model = 1723 ft³

5) The percentage of the original tank is 51200% of the mock-up

Step-by-step explanation:

4) ∵ The volume of the main tank is 882,158 ft³

∵ The dimension of the scale model is 1/8 of the original model

∵ V model/v original = (dimension model/dimension original)³

∴ Volume model/882,158 = (1/8)³

∴ Volume model = (1/512) × 882,158 = 1722.965 = 1723 ft³

5) The percentage of the original tank is

    (882158/1722.965) × 100% = 51200%

the expected value of the random variable : 0, 1 and 2
