Human Geography homework help please?!?

Question

Hey guys, I would appreciate it soooo much if you could see if you can figure out this homework sheet? I have been working on it forever and can't get it.

Here is the information that I have been provided - 
Population profile for Mongolia in 2010


Total Population: 3,086918
Crude birth rate: 21.03
Crude death rate: 6.08
Total fertility rate: 2.22
Net Migration: 0
Infant mortality: 38.56/1,000 births
Life expectancy: 67.98 years
Land area: 1,564116 sq km
Arable land: 76%
Employed in agriculture: 34% (@1/2 of those ages 15-64)

Ages 0 - 14 = 28.1% of population with 436,391 males and 418,923 females
Ages 15 - 64 = 67.9% of population with 1,031,819 males and 1,033,806 females
Ages 65+ = 4% of population with 52,439 males and 67,773 females

And this is what the worksheet says - 

Arithmetic density = _______________________
Physiological density = _____________________
Agricultural density = _________________
Doubling time = _____________________
Dependency ratio = _______________________
Sex ratio for ages 0 - 14 = __________: 100
sex ratio for ages 15 - 64 = ____________:100
sex ratio for ages 65+ = ____________:100

then it wants me to draw a 3-bar population pyramid for Mongolia.

I'm willing to pay anyone who can do this! I know you're having to take my word for it, but i will if you can help me get the correct answers to these. thanks!!

- Arithmetic density: The total number of people / area of land 3.086918/1.564116= 1.9735 person/sq km
- Physiological density: The total population / area of arable land. 3.086918/(1.564116x0.76)= 2.5968 per/sq km of arable land.
-Agricultural density: The total rural population / area of arable land. (3.086918x0.34)/(1.564116x0.76) = 0.8829 farmer/sq km of arable land
- doubling time: 70/(2.103-0.608) = 46.82 years. or 48.1 years if log2 is rounded to 72
- Dependency ratio: 100 x (436,391+418,923+52439+67,773) / (1,031,819+1,033,806) = 47.2266
- sex ratio 0-14: 436391/418923= 1.0417
 15-64= 0.998
 65+= 0.7737

use excel sheet to draw table using these numbers.
	male	female
65+	0-52439	67,773
15-64	0-1031819	1,033,806
0-14	0-436391	418,923

about 30 km under your ft is the Earth’s mantle. It’s a area of superhot rock that extends all the way down to the Earth’s midsection. This area is so warm that molten rock can squeeze out and variety massive bubbles of liquid rock spoke of as magma chambers. This magma is lighter than the encircling rock, so it rises up, searching cracks and weak point contained in the Earth’s crust. even as it ultimately reaches the floor, it erupts out of the floor as lava, ash, volcanic gasses and rock. It’s spoke of as magma even as it’s less than the floor, and lava even as it erupts onto the floor. Does that help? Ya, i understand I hate geography too. I stink at it! sixth grade geography is the most terrible ingredient contained in the completed international! convinced, I do this for my homework each and each of the time. isn't it effective!?
