ABF= 28 degrees
BCD= 28 degrees since vertical angle are congruent
ABC= 180 -28 = 152 degrees
[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5

Two rolls of die
one of the outcomes is 6
atleast one is 6
Required
P(E|A)
First, list out the outcome of each


So:

Where:



So:

Answer:
y = k/x
k = y.x = 7 x 9 = 63
Hence equation is
yx = 63
