Thomas has devised a scheme for splitting up the test and training set. For each row from coordinates: Rows for Stanford students have a 50% chance of being placed in the train set and 50% chance of placed in the test set. Rows for Berkeley students have a 80% chance of being placed in the train set and 20% chance of placed in the test set. Given that a row is in the test set, what is the probability that it corresponds to a Stanford student? Assign that probability to prob_furd.

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

using pemdas, (order of operations) you'll see the answer is 24.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
