H.W 1: A (6 m) layer of sand overlies a (5 m) thick layer of clay with a sand deposit beneath. The water table is to be lowered permanently from (1 m) below ground level to (4 m) below ground level, by pumping from the sand over a period of (6 weeks). Determine the settlement due to consolidation of the clay layer 6 months) from the start of pumping. For the clay: m2 my = 0.45 m² / MN and cy = 5.5 year 0.008 0.031 0.071 0.126 0.196 0.287 0.403 0.567 Ty U% 10 20 30 | 40 50 60 70 80

Step-by-step explanation:

To complete your questions, the missing parts are shown below

                   Sample 1                  Sample 2        total

Country            5                               3                 8  

Pop                  4                                3                 7

Classical          3                                5                 8

Jazz                 2                                4                  6

Rock                6                                5                11

Total                20                               20             40

The proportion that would predict the number of jazz songs that Mr. McElroy has stored on his MP3 player is given by 6/20

Hence, our required proportion would be

6/20 =x/2000

We cross multiply  

20x = 2000 x 6

20x = 12000

Divide both sides by 20

X = 12000/20

X = 600

Hence, our required proportion would be

6/20 = x/2000
