Answer:
(a)
(b) After an infinite period of time; we will get back to a result similar to after the two time period which will be
Step-by-step explanation:
The Markov Matrix can be interpret as :
From (a) ; we see that the initial population are as follows: 130 individuals in location 1, 300 in location 2, and 70 in location 3.
Le P represent the Population; So ;
The objective is to find How many are in each location after two time periods;
So, after two time period ; we have the population
where;
Now; Over to after two time period ; when the population
(b) The total number of individuals in the migration process is 500. After a long time, how many are in each location?
After a long time; that is referring to an infinite time (n)
So;
where ;
; if we determine the respective values of we will always result to the value for ; Now if is said to be a positive integer; then :
After an infinite period of time; we will get back to a result similar to after the two time period which will be
Answer:
(7/12)*pi
Step-by-step explanation:
ACD/circumference = [35*pi/180]/2pi
<=>
ACD/[2*pi*3] = [35*pi/180]/2pi
The answer is B) all sides are the same length. Hope this helps! :D
Answer:
A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68
Step-by-step explanation:
Consider the provided information.
A random sample of 21 checking accounts at the bank are chosen,
That means n=21
df = n-1
df = 21-1=20
We need to Construct and interpret a 95% confidence interval.
Determine t critical value for 95% confidence interval.
0.95=1-α
α=0.05
The sample size is small and it is a two tailed test.
From the t value table confidence interval is 2.086
An average daily balance is $303 and a standard deviation of $63.
Substitute the respective values.
A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68
