Given:
A driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m.
To find:
The current location of the driver.
Solution:
In this problem, negative sign is used for downward direction or the distance below the surface of the water.
Initial location = -15 m
Dives down by 6m, it means - 6m, then rises 4m, it means 4 m.
Now, the current location is



Therefore, the correct location of the driver is at -17 m it means her is 17 m below the surface of the water.

Answer:
600 baboons
Step-by-step explanation:
Half the number of marked baboons showed up in the sample, so we expect the sample size to be about half of the total population. 300 is half of 600.
___
Many assumptions are involved in such an experiment and analysis. Not the least of which are the assumptions that the marked baboons end up evenly distributed through the population, and that the sample is a fair sample of the entire population.
Answer:
1) 12.7 cm
2) 8580.24 cm³
Step-by-step explanation:
given,
Radius of moon(Rm) = 1700 Km Radius of Earth(Re) = 6350 km
Model radius of Moon(Mm) = 3.4 cm
2) Volume of earth model =
= 
= 8580.24 cm³
1) radius of earth = 
= 
= 12.7 cm
