18. Given the following four lines, pick the true statement. Line 1:
Line 2:
Line 3:
3y = 4x + 3
4y = 3x - 4 3x + 4y = 8
Line 4:
4x + 3y = -6
O
A. Lines 1 and 4 are parallel
B. Lines 2 and 3 are parallel
C. Lines 2 and 4 are perpendicular
D. Lines 1 and 2 are perpendicular

Lines 2 and 4 are perpendicular

Step-by-step explanation:

Line 2: 4y=3x-4

y=3/4x - 1

Line 4: 4x+3y=-6

3y=-6-4x

y=-2 - 4/3x

The two lines are perpendicular since -4/3= - (inverse of 3/4)

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
