#36.The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 5054 births, 4567 deaths, 25 immigrations and 52 emigrations.
Calculate the per capita growth rate. Express your answer as a value between 0 and 1 rounded to two decimal places.  If the population is decreasing indicate this with a negative sign.
given: Ni=11800- intial population
birth=5054
immigrations =25
death=4567
emigrations=52
cgr= ∆N/Ni.
cgr=(b+i)-(d+e)
cgr=(5054+25)-(4567+52)
cgr=4060/11800
cgr=0.0389 or 0.04?

#38.In a particular population of Paramecium species, 30 Paramecia were found in 4 mL of sample pond water. At another location, 85 Paramecia were found in 40 mL of sample pond water.
What is the change in density of the Paramecium species?
Express your answer rounded to two decimal places.
 Paramecia/mL

given: V=4mL, 40mL
Ni=30
Nf=85
find dp=?
Dp=N/V
85-30/40-4

Dp=55/36
Dp=1.527777778 or 1.53?

i have no idea if this is right or not. Have given the formulas's i used but if i used the wrong formula here is the biology 30 data booklet first page has all of the formulas needed for these questions:
