Question 2 (4 points) (07.01)
1
Consider two events such that P(A) =
6
P(B) =
2
, and P(ANB) =
15
. Are events A and B independent events? (4 points)
O a
Yes, they are independent because P(A) - P(B) = P(ANB)
No, they are dependent because P(A) - P(B) = P(ANB)
Ob
oc
Yes, they are independent because P(A). P(B) = P(ANB)
Od
No, they are dependent because P(A) - P(B) + P(ANB)
Question 3 (4 points)
(07.01)

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

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.
