Circumference=2pi*r
20.7=2pi*r
r=3.296 or 3.3
A=pir^2
a=34.1946 or about 34.19
Answer:
336 squirrels
Step-by-step explanation:
-This is a Mark-Recapture method.
-The population is estimated using the formula:
![N=\frac{MC}{R}](https://tex.z-dn.net/?f=N%3D%5Cfrac%7BMC%7D%7BR%7D)
where:
- N-is the estimated population size.
- M-is the number of individuals tagged
- C- is the total number captured the second time(both tagged and untagged)
- R-is the total number of tagged individuals recaptured.
#We substitute our values as follows to estimate N:
![N=\frac{MC}{R}\\\\=\frac{114\times 97}{33}\\\\=335.0909\approx336](https://tex.z-dn.net/?f=N%3D%5Cfrac%7BMC%7D%7BR%7D%5C%5C%5C%5C%3D%5Cfrac%7B114%5Ctimes%2097%7D%7B33%7D%5C%5C%5C%5C%3D335.0909%5Capprox336)
Hence, there are approximately 336 squirrels in the conservation area.
*population is always rounded up to the next whole number.
Answer:
2 and -9
Step-by-step explanation:
2 times -9 is -18
2 plus -9 is -7
Hope this helped!
Number of Neutrons = Atomic mass - Atomic number
= 16 - 7 = 9
In short, Your Answer would be 9
Hope this helps!
Answer:
x=9
Step-by-step explanation:
given;
x\y = 3\4
to find;
x\12=?
solution;
using both equations,
3\4=x\12
by cross multiplication,
36\4=x
9=x
x=9
