Answer:
And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution 
and for this case we know that the distribution is given by:
And the standard error would be:
And replacing we got:
Step-by-step explanation:
For this case we know the population deviation given by:

And replacing we got:
Answer:
5a - 30
Step-by-step explanation:
Okay, so a kilometer=1000 meters, knowing that we can multiply 350*300 for the area, which would give us 105000 meters squared, then we divide 105000 by 1000, giving us 105 square kilometers.
The formula for the volume of a cone, V, is:
V = [1/3] * π * (radius)^2 * height
Here radius = 6 feet / 2 = 3 feet
Height = 15 feet
V = [1/3] π (3 feet)^2 * 15 feet = 45π feet^3
Answer: 45π feet^3
