What is the slope of 7x+3y<-26

pogonyaev

Answer:

-7/3.

Step-by-step explanation:

Convert to the form y < mx + c where m is the slope:

7x + 3y < -26 Subtract 7x from both sides:

3y < -7x - 26 Divide through by 3:

y < (-7/3)x - 26/3

So the slope is -7/3.

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
