Answer:
The probability that the random you randomly select species that are greater than 200 kg is = 7/62
Step-by-step explanation:
Step One: Load the data set in to the R work space
data(mammals,package="MASS")
attach(mammals)
Step 2 : Obtain the list of the species that are greater than 200 and store it on y variable.
y <- subset(mammals,body>200)
Step Three : Obtain the total size
nrow(mammals)
Step Four : Obtain the sum of species greater than 200
sum(body > 200)
total size = 62
size with body > 200 = 7
hence
required probability = 7/62
We are given:
There seems to be nothing I can do to simplify this equation. However, I can factor out an since they both have at least an
. Here is what we get:
This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.
Answer:
$10579.49
Step-by-step explanation:
The formula for amount gotten after a period of time (in years) on a principal which is compounded continuously is given as:
where P = principal (amount borrowed)
r = interest rate
t = number of years
Peter accumulated $7,500 in credit card debt with interest rate as 3.5% per year and he does not make any payments for 10 years.
Therefore, his debt is:
A = $10579.49
He will owe $10579.49 after 10 years
