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
Lets use substitution
y=7x-10
y=-3
so
-3=7x-10
7=7x
1=x
now lets check
y=7(1)-10
y=-3
therefore both equations have the same value
Answer:
I think its 4.10152
Step-by-step explanation:
The answer is
(0,0)
Goodluck
2x-12=4
put the 12 in place of y since they equal each other
2x=16
add 12 to both sides
x=8
divide both sides by 2
