Answer:
181
Step-by-step explanation:
The tagged deer seem to represent about 17/110 of the population. Since there are 28 deer with tags, the population (p) is estimated to be ...
110/17 = p/28
p = 28(110/17) ≈ 181
There are about 181 deer in the woods.
By the way, it's pi, not pie. just wanted you to know as you may lose marks in tests for spelling (but i may be wrong)
we know circumference is pi multiplied by the diameter.
the diameter is 2x the radius
we can re-arrange the first fact to get:
diameter (or 2x radius) = circumference divided by pi.
since the circumference is 24pi we can cancel off pi from the circumference (24pi) and pi.
now we have the diameter = 24
since the diameter is 2x the radius you divide both sides by 2 and get:
radius=12cm
We are interested in selecting 2 people from the 7-person task force.
n = 7
r = 2
nPr = n! / (n-r)!
7!

Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° = 
, then
tanf° = 
= 
= 
= ( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
