Researchers found that there are 164 raccoons on an island when they return a year later they find that there are 366 what is the growth factor for the raccoon population

Growth Factor = 2.2317 (rounded to 4 decimal places)

Step-by-step explanation:

The formula we will use is the growth formula, that is:

Where

F is the future population (366)

P is present population (164)

r is the growth rate (we need to find this)

"(1+r)" is the growth factor

t is time in years (t=1 given)

Now, substituting, we find:

We haven't boiled down to r = something because we don't want growth rate (r), rather, we want growth factor (which is 1+r). So

Growth Factor = 2.2317

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
