<h2>Population becomes 550 in 27 days</h2>
Step-by-step explanation:
The population of spiders in a lab is modeled by the function
, where
represents the number of days since population was first counted.
Consider that after
days, the population of spiders has grown to 550. We need to find such
.


Applying logarithm on both sides,


∴ It takes about 27 days for the population to become 550.

Answer:

Step-by-step explanation:
z=5x-11y
+11y on both sides
z+11y=x
divide by 5 on both sides

Step-by-step explanation:
To obtain, the maximum likelihood ratio, we use the following method.
l(σ) = Xn
i=1 "
− log 2 − log σ −
|Xi

Let the derivative with respect to θ be zero:
l
0
(σ) = Xn
i=1 "

= 0
and this gives us the MLE for σ as
σˆ =

i=1 |Xi

Again this is different from the method of moment estimation which is
σˆ =
sPn
i=1 X2
